2 Safety Information Read through and communicate safety information to the end user of this Waterous Fire Pump. WARNING Death or serious personal injury might occur if proper operating procedures are not followed. The pump operator, as well as individuals connecting supply or discharge hoses to the apparatus must be familiar with these pump operating instructions and manuals for the apparatus, water hydraulics and component limitations. WARNING Pressure Hazard. May result in personal injury. Pressure to connection or removal of hoses, caps or other closures with pump intake or pump discharge connections, relieve pressure by opening drains or bleeder valves. Bleeder valves should also be used while filling a hose connected to an intake with water.. WARNING Scalding Water Hazard. May result in serious burn. When operating the pump, be sure to open at least one discharge valve slightly to prevent the pump from overheating. If the pump runs for a few minutes completely closed, it may heat the water enough to scald someone when the valve is opened. Overheating can damage the packing, seals and other pump parts. If the apparatus builder has installed a by-pass system or other provision designed to prevent overheating, opening a discharge valve may be unnecessary. WARNING Rotating Parts Hazard or Unexpected Truck Movement. May result in serious personal injury or death. Stop the engine, set parking brake and chock the wheels before going under the truck to adjust packing or to check packing gland temperature. OEM Installation Warnings WARNING Unexpected Truck Movement. May result in serious personal injury or death. Failure to properly install the pump shift control and pump shift indicator system in the apparatus or failure to incorporate in the Pump Operator s Panel Engine Speed Interlock System may result in unexpected truck movement which may result in serious personal injury or death. WARNING Inability to Pump Water. May result in serious personal injury or death. Failure to properly install the pump shift control and pump shift indicator system in the apparatus or failure to incorporate in the Pump Operator s Panel Engine Speed Interlock System may result in unexpected truck movement which may result in serious personal injury or death. WARNING Exceeding Power Train Torque Ratings. May result in inability to pump water causing serious personal injury or death. This fire pump may have the capability under certain pumping conditions to exceed the torque rating of the power train. A means to control the engine output to a torque level no greater than the power train s continuous-duty torque rating must be considered when specifying power train components and engine control system parameter.

Drop values vary for other output ratios, see dimensional drawings for specific drops by ratio. Drop Dimensions NOTE: Remove shipping brackets and discard. Do not use for mounting pump. Select a mounting location which will make the pump and its accessories readily accessible for maintenance and which will make the pump driveshaft parallel with the output shaft of the chassis transmission or transfer case. Also, select the location so that when the apparatus is loaded, the universal joints on the propeller shaft will have a proper working angle. Note that the C20 Series transmission is available with a range of drop sizes (see Table 1 and Figure 1, Dimension A ). Figure 1. Drop Size Dimensions Drive Line Angles Table 2 gives maximum universal joint angles for installation where propeller shaft flanges are parallel and yokes are aligned. Refer to this when positioning a pump to determine proper shaft angles. Be sure to keep at least a minimum of 1 U-joint operating angle, but do not exceed those specified in the table. This is the preferred method of propeller shaft installation. For additional information on this method, or for alternative methods, see driveshaft installation guidelines such as Spicer /Driveshaft Installation Techniques. CAUTION Be sure the propeller shafts used are of the slip-joint design. Frame deflection, temperature changes and similar factors may cause a propeller shaft without slipjoints to produce severe axial loads on the bearings and damage the pump / transmission. Table 2. Maximum U-joint Operating Angles Driveshaft RPM Maximum Operating Angle NOTE: The angles shown in the table above are the maximum U-joint operating angles recommended by Waterous and are directly related to the speed of the driveshaft. Any U-joint operating angle greater than 3 will lower the U-joint life and may cause vibration 1. 1 From Spicer Driveshaft Installation Techniques, Form J F-1031, Section Page 4 of 19

5 CGVG Series Pumps with C20 Series Transmission Figure 2 shows a typical installation of a CGVGC20 where the pump is mounted on angle brackets attached to the outside of the chassis frame rails. To mount the pump, create angle brackets that will attach the pump to the vehicle's chassis. The CGVGC20 is equipped with two (2).563 (9/16) in. through holes on each side of the crosspipe. To help create the angle brackets, Figure 13, Pump Mounting Holes in Angle Brackets, shows the locations of the holes in the crosspipe. Drill a suitably sized hole in the angle bracket where the corresponding hole in the crosspipe is located. Using only one tapped hole on each side of the adapter, fasten the angle bracket to the pump. Repeat this procedure for each side of the pump. Fasten the angle brackets to the chassis frame rails using a 3-point mounting technique shown in Figure 3. This mounting technique allows for slight truck frame twist. NOTE: Tighten the mounting screws to standard torque specifications. Figure 3. Three-Point Mounting Diagram Adjust pump angle to achieve proper driveline angles (See Table 2). 1/2 Mounting Screws, Grade 5 Minimum (One bolt on each side of adapter - 4 per pump) CAUTION Do not use the 4-bolt mounting pads on the output shaft side of the C20 case for mounting CGVG model pumps to prevent excess stress on the transmission case. Figure 2. CGVGC20 Mounting Chassis Frame Rail Angle brackets on both sides (See Figure 13 on Page 10 for Mounting Holes). Anti-seize should be applied to the shaft threads before installing end yoke or companion flange. Do not reuse self-locking nuts.

7 CGVG Series Pumps with WB Series Transmission Figure 6 shows a typical installation of a CGVGWB where the pump is mounted on angle brackets attached to the outside of the chassis frame rails. To mount the pump, create angle brackets that will attach the pump to the vehicle's chassis. The CGVGC20 is equipped with two (2).563 (9/16) in. through holes on each side of the crosspipe. To help create the angle brackets, Figure 13, Pump Mounting Holes in Angle Brackets, shows the locations of the holes in the crosspipe. Drill a suitably sized hole in the angle bracket where the corresponding hole in the crosspipe is located. Using only one tapped hole on each side of the adapter, fasten the angle bracket to the pump. Repeat this procedure for each side of the pump. Fasten the angle brackets to the chassis frame rails using a 3-point mounting technique shown in Figure 7. This mounting technique allows for slight truck frame twist. NOTE: Tighten the mounting screws to standard torque specifications. Figure 6. CGVGWB Mounting Chassis Frame Rail Oil Pressure Gauge An oil pressure gauge may be used to show that the transmission lubrication pump is working. Following are guidelines on installing an oil pressure gauge. 1. Mount the gauge away from the operator's panel and preferably at the right hand side panel (passenger or curb side). This will prevent a pumper from being shut down due to a failed pressure gauge. NOTE: Do not use a gauge with a low pressure zone marked in red or wording on the gauge face indicating that operation in the low pressure zone is dangerous. 2. The gauge should be identified as: FOR MAINTENANCE CHECKS ONLY. 3. The end user should be instructed to use the gauge only as part of monthly maintenance checks. These checks should be done while the lubricant is not hot and with the pump turning fast enough to give a good pressure indication on the gauge. 4. No specific pressure value should be given to prove the lubrication pump is working, but instead, a range from 3-30 PSIG is satisfactory. Note that any movement of the pointer on the gauge with a change in pump speed indicates that the lubrication system is working. Figure 8. Oil Pressure Gauge Angle brackets on both sides (See Figure 13 on Page 10 for Mounting Holes) Anti-seize should be applied to the shaft threads before installing end yoke or companion flange.

12 CGV, CGVN and CGVR Series Pumps with C20 Series Transmission Figures 14 and 16 shows the mounting areas on CGV, CGVN and CGVR pumps. There are mounting holes on the output side of the transmission as well as the pump intake. To mount the pump/transmission to the vehicle chassis, attach brackets (not supplied by Waterous) on either side of the transmission. Position the pump/transmission within the vehicle frame rails, blocking temporarily to provide correct shaft angularity. With the pump/transmission in the correct position, secure the brackets (not supplied) to the vehicle frame using a three point mounting technique. The bracket on one side of the transmission shall use only one bolt when attaching to the rail. The bracket on the other side of the transmission should be attached to the chassis rail using two bolts. This three point technique will allow for slight vehicle frame twist without undue stress on the pump/transmission assembly. The transmission cap also contains five (5) mounting holes for further support of the CGVC20, CGVNC20 or the CGVRC20. Support the pump by fashioning a bracket (not supplied by Waterous) and mount it to the intake side of the pump using the existing intake mounting screw holes. NOTE: You will need to remove one or more intake mounting screws from the intake side of the pump and replace them with longer screws to compensate for the thickness of the bracket.

18 Optional Corrosion Protection Zinc Intake Screens Waterous offers zinc intake screens that fit 4, 4-1/2, 5 and 6 inch intake fittings sizes. The screen is designed to fit in the counter bore in the inside diameter of the fittings. There must be a strong electrical contact between the screen and the intake fitting. Remove any corrosion, debris or paint from the counter bore that will insulate the screen from the intake fitting. If the screen does not fit tightly, adjust the gap of the slot on the outside diameter of the screen to ensure a tight fit. NOTE: Zinc intake screens are die-cast which results in a slight taper from one side to the other. Install the screen with the thinner cross-section facing out to minimize flow restriction. Zinc Anodes Zinc anodes may be mounted in the intake piping or, if no intake pads are available, in the discharge piping. NOTE: The zinc must make contact with water to be effective. Do not paint or use any other coating on the zinc elements. Zinc anodes are available for the following: Pads machined with 2-1/2 in., 4-bolt mounting patterns Pads machined with 2-1/2 in. or 3 in. NPT taps. Zinc Anodes - Bolt On Pads Machined with 2-1/2 in., 4-bolt Mounting Pattern Pads Machined with 2-1/2 in., 4-bolt Mounting Pattern Zinc Anodes - Threaded Pads Machined with 2-1/2 in., or 3 in.
