SECTION 3: INSTALLATION IMT CAS45RS AND CAS45RS-CW 3.3 DETERMINING THE COMPRESSOR UNIT MOUNTING LOCATION When determining the location to mount the CAS45RS unit, the following criteria must be taken into consideration: Refer to Section 3.5, Installation. The location must allow for the machine dimensions (Figures 3-3A through 3-3D), and additional space requirements for minimum cooling, access and maintenance. The mounting surface must be level and able to accommodate the four [4] mounting bolts of the base frame. Refer to Figures 3-3A through 3-3D for mounting hole location dimensions. The mounting surface must be able to support the units weight (196 lbs.). The external display must be easily visible to the operator. It is recommended, for most installations, to mount the compressor on the driver s side of the vehicle. The unit should be situated in such a manner that the fan (rear) and intake side (front) are not obstructed. Do not place the compressor in any location where it can intake exhaust fumes, dust or debris. 3.4 HYDRAULIC SYSTEM OVERVIEW IMPORTANT IMT highly recommends consulting a hydraulic supply expert for specifying the correct hydraulic supply components for vehicle-side integration (including oil reservoir size, hydraulic pressure relief, hose size, etc.) for your application. IMPORTANT Contaminated hydraulic fluid allowed to enter the pump will cause malfunction of the pump controls. Hydraulic system hoses must be flushed and cleaned prior to being connected to the unit. Refer to Figures 3-3A through 3-3D for hydraulic pump system connections. Please take into consideration the following: The hydraulic flow and pressure requirements of the system. A continuous hydraulic load is necessary when compressor is running. The duty cycle and ambient operating temperatures. Other hydraulic equipment which may share that same hydraulic supply system (IMT recommends a dedicated pump and hydraulic circuit). WARNING Follow all applicable safety recommendations as outlined in Section 1: Safety of this manual. WARNING Improperly, or non-connected lines will damage the equipment. The hydraulic hoses must be run to the machine. Verify that hoses are hooked up properly to ensure proper flow. Also, verify that the hoses are laid out properly so that no chafing or kinking of the hoses is possible. Refer to Section 7.16, Hose Installation Guide, for assistance with proper hose layout and connecting functions. NOTE The temperature of the hydraulic oil should not exceed 160 F due to the rating of the IMT-supplied hydraulic motor. 3.4.1 HYDRAULIC SYSTEM FILTRATION IMT recommends using a 10 micron oil filter on the hydraulic oil return line. Flow rating of the filter must be equal to, or greater than, the maximum GPM at which the system will be operated. PAGE - 8 Manual #99906316 Rev.0

SECTION 3: INSTALLATION 3.4.2 HYDRAULIC OIL RESERVOIR 3.4.2.1 DETERMINING RESERVOIR SIZE In a conventional hydraulic system, minimum tank size, in gallons, should be equal to the maximum GPM flow rate, times two (x 2). 3.4.2.2 DETERMINING RESERVOIR SHAPE A KEY A B IMPORTANT Use only a filter that is specifically intended for hydraulic systems. The reservoir structure should be tall and narrow rather than shallow and broad (Figure 3-1). A tall, narrow tank is recommended because: 1. The oil level is well above suction line opening, avoiding the possibility of drawing air into the pump due to a vortex or whirlpool effect within the tank during operation flow. DESCRIPTION B PREFERRED SHAPE: TALL AND NARROW SHAPE TO AVOID: BROAD AND SHALLOW Figure 3-1: Reservoir Design Shape 2. Allows for better oil level tolerance level of the system if vehicle operates at an unusual (slightly off level) vehicle angle. 3. To keep return flow well below the surface so it does not break the surface and cause aeration (cavitation) of the oil. 3.4.2.3 MANDATORY RESERVOIR FEATURES The reservoir should incorporate the following design features: In terms of location of the reservoir tank within the hydraulic system, note that the hydraulic pump s inlet line (suction line out from the reservoir to the pump) should be located near the bottom of the tank, well below the oil level. The suction line should protrude a minimum of two (2 ) inches into the reservoir to keep it away from potential contaminant surface buildup. A baffle or baffles should be included to prevent sloshing, or centrifugal motion of the oil; the goal is to break up direct flow of the oil from the return point to the suction point. This allows for the cooling action contact with the tanks inner surfaces, and promote separation of any air or contaminants that interact with the flowing oil. An ideal baffle design would position several (but not too many) baffles to promote an S shape flow within the reservoir, as viewed from above. The area of the end gaps should be at least twice the area of the suction line diameter. A drain port with plug, situated at the lowest point of the reservoir, is needed to assure complete draining. It should be installed using an adapter or housing which does not protrude above the inner surface of the floor of the tank. It should be visible and accessible for removal, with sufficient space available for catching the waste oil. If the return line entrance to the tank is located near the top, it should be extended downward within the tank to minimize foaming and aeration of the circulating oil. This extends oil integrity, which in turn helps to maintain system performance and reliability. Manual #99906316 Rev.0 PAGE - 9

SECTION 3: INSTALLATION IMT CAS45RS AND CAS45RS-CW An in-line filter on the return line is needed to protect the system against contaminants being introduced into the oil. The filter should be mounted externally from the reservoir in a location that allows for easy of service access. A breather and fill cap is needed at the oil fill port, which needs to be located above the system oil level. The breather cap acts to both filter air that is drawn into the reservoir as the oil level diminishes, and bleeds air out as the level is regained. This maintains constant atmospheric pressure in the air volume within the reservoir. A sight-glass provides a direct visual indication of the oil level without having to open, or otherwise access, the reservoir. 3.4.2.4 RECOMMENDED RESERVOIR OPTIONS Although not essential for an adequately functioning reservoir, the following components will contribute to maximize the hydraulic system s efficiency and maintain a quality operational level. Magnetic drain plug: Attracts and concentrates ferrous contaminants at the drain plug source for easier accessibility and removal when cleaning tank interior. A temperature gauge: Located in approximation to, or built in to, the sight glass assembly allows for temperature reading at a glance. Filler port strainer: Prevents large contaminant particles from blending with system oil when adding new oil. Return line diffuser (splash) plate reduces velocity of oil flow before return oil stream merges with the main reservoir oil volume. A reservoir heater: For those systems that are exposed to cold climate ambients, having the ability to preheat the hydraulic oil prior to start up will make for easier startups, and reduce the strain of warming up the system under adverse cold conditions. 3.4.2.5 RESERVOIR FEATURES TO AVOID A strainer used to screen the suction line is not recommended for systems designed for mobile equipment use. Having equipment that likely experiences long suction lines, cold startups and non-tracked or infrequent maintenance practices may cause this strainer to potentially promote system strain (cavitation) than prolong fluid integrity through filtration. A pressurized reservoir is not recommended for vehicles, as its complexity invites too much potential for loss of system reliability if it is not properly maintained. 3.4.3 RECOMMENDED HYDRAULIC SYSTEM SPECIFICATIONS WARNING Do not operate machine without hydraulic system completely assembled. Refer to Figures 3-3A through 3-3D. Flow controller is optional to reduce flow if necessary. Consult IMT. HYDRAULIC LINES The following is a minimum requirement and NO quick disconnects may be used. Lines are to be kept as straight and short as possible. Pressure port = Standard, #12, 3/4 hose (located at manifold block) Load sense = #4 JIC = 1/4 hose (Used for closed center system only) Pressure relief/case drain = #6 JIC = 3/8 hose Hydraulic suction = Standard, #16, 1 hose 3.4.4 STANDARDS GUIDELINES Hydraulic pressure relief factory set at 3200 psi.

SECTION 3: INSTALLATION 3.5 INSTALLATION 3.5.1 MACHINE LOCATION It is vital to locate the machine so that there is no restriction of cooling air through the enclosure (Refer to Figure 3-2). Cooling air enters the enclosure at the rear (cooler) package end of the machine, passes through the cooler and exits through vents in the upper sides and the front. 3.5.2 CLEARANCES A KEY A B C D E Refer to Figure 3-2. Ensure that adequate surrounding clearance space exists around the machine to allow for adequate cooling ventilation through the canopy shroud, unobstructed service access, and a clear B DESCRIPTION BACK SIDE CLEARANCE = 10 MINIMUM LEFT SIDE CLEARANCE = 10 MINIMUM FRONT SIDE CLEARANCE = 10 MINIMUM I RIGHT SIDE CLEARANCE = 10 MINIMUM TOP SIDE (OVER HEAD) CLEARANCE = 42.63 MINI- MUM, FOR (OPENED) HOOD ACCESS I The front (control panel) side may need additional clearance for both access to the service panel there, and/or access to view the controller panel. Figure 3-2: Minimum Installation Clearances C E D view of the control panel. An approximate recommendation of ten (10) inches clearance, minimum, is needed for proper cooling circulation, plus any additional service access room included where needed. 3.5.3 MOUNTING Mounting surface or support should be adequate for the weight of the machine (196 lbs.), and should be level for normal operation. Mounting holes are located in the frame footing for four (4) 1/2 hold down bolts. 3.5.4 SERVICE CONNECTIONS Refer to Figure 3-3A through 3-3D. Service connections are conveniently grouped at the lower rear section of the unit in the base frame. 3.5.5 ELECTRICAL CONNECTIONS Refer to Figure 3-3A through 3-3D. This system is offered with either 12V DC or 24V DC circuits. 3.5.6 HYDRAULIC SUPPLY CIRCUIT Refer to schematic drawings in Sections 7.15A through 7.15D. It is recommended that the compressor unit possesses a separate pump/flow/return hydraulic circuit to other hydraulic equipment. This is to prevent the possibility of pressure/flow drops that may occur if other hydraulically-powered equipment is activated during compressor operation, which may in turn, cause the compressor to stall out. Alternatively, use of a diverter valve will permit hydraulics to power different equipment selectively. 3.5.7 ROUTING Refer to Figures 3-3A through 3-3D, and the wiring diagram. Ensure that all supply hoses and electrical wiring are correctly specified, adequately supported, and do not touch or rest on any sharp edges. Wiring should be protected with split loom to prevent corrosion, and consequently, loss due to down time. Manual #99906316 Rev.0 PAGE - 11

SECTION 5: MAINTENANCE SECTION 5: MAINTENANCE 5.1 GENERAL INFORMATION A good maintenance program is the key to long compressor life. This section contains a program that, when adhered to, should keep the compressor in top operating condition. However, it should be understood that these intervals are for normal operation in a good clean environment. More frequent inspections, oil changes and general maintenance should be carried out in dusty environments, high ambient temperatures, heavy load applications or extended light load conditions. Follow the prescribed periodic maintenance schedules given in Table 5A: Routine Maintenance Schedule, in this section as recommended. Failure to follow the prescribed periodic maintenance at the recommended intervals will impair the package safety, performance characteristics, shorten the package s life, and will negatively affect the warranty coverage of the package. IMPORTANT It is important to keep in mind that operating the compressor package in a severe environment may require more frequent service intervals than prescribed in the periodic maintenance schedule. Before starting the compressor system, inspect the machine package for any suspect condition that may cause a safety hazard or hamper operation. Replace damaged components with Genuine IMT Replacement Parts. WARNING Follow all applicable safety recommendations as outlined in Section 1: Safety of this manual. WARNING DO NOT remove caps, plugs and/or other components when compressor is running or pressurized. Stop compressor and de-pressurize system prior to maintenance of system. Wear personal protective equipment such as gloves, work shoes, and eye and hearing protection as required for the task at hand. WARNING DO NOT work on any electrical components unless the battery is disconnected. WARNING Follow the prescribed periodic maintenance (PM) schedule as recommended. Perform the required PM schedule at recommended intervals. Failure to follow this prescribed periodic maintenance at the recommended intervals will impair the package safety, performance characteristics, shorten the package s life, and will negatively affect the warranty coverage of the package. CAUTION Compressors and drive motors generate heat and create hot surfaces. Use caution when operating or servicing the compressor system. Some surfaces and components may be hot. IMPORTANT It is important that the compressor oil be of the recommended type and that it is inspected and replaced together with the oil filter and air filters, and (when necessary) the coalescer separator in accordance with this manual.

SECTION 5: MAINTENANCE IMT CAS45RS AND CAS45RS-CW IMPORTANT DO NOT mix oils of different types. Use only original IMT equipment filters. Mixing of different types of oils, or using non-imt equipment filters will VOID THE WARRANTY. 5.2 MACHINE MAINTENANCE SCHEDULE Refer to Table 5A: Routine Maintenance Schedule. A routine maintenance schedule based on time and/or hours logged, is given in Table 5A. The intervals are determined from machine usage under typical operation conditions. However, the operator must be aware that operating conditions will vary depending on such things as specific customer requirements, environmental temperatures and cleanliness of the ambient air. With this in mind, the specifications given in Table 5A should be used as a guideline instead of a fixed agenda. A safe approach to routine maintenance would be to perform the given maintenance task more frequently under harsher conditions. IMT provides a routine maintenance parts list in Section 7, Table 7A. Should a non-routine part need replacement or servicing, peruse the various parts list illustrations in Section 7 to help determine the exact part and part number in question. Our parts and service departments are ready to assist in identifying and/or replacing non-routine parts. For assistance in obtaining routine maintenance or replacement parts, consult Section 7.1, Parts Ordering Procedure, and Table 7A: Recommended Spare Parts List. 5.3 REPLACEMENT PARTS Replacement parts should be purchased through your local IMT representative or where the compressor system was purchased.
