The size ranges offered by Intensity allow you to mix or match components to meet actual job requirements, thus eliminating the need to use oversized or undersized equipment. quipment sized to meet the actual load will provide better operating economy, better humidity control, and longer equipment life. With an air cooled system, you have no water or sewer connections to make, and no troublesome and costly water treatment problems. Since the condensing unit is located outside the building, and the low profile air handling unit can be installed in the drop ceiling or in the conditioned space, you will not need a separate equipment room which takes up valuable building space. emote mounting of the already quiet condensing unit keeps the compressor and condenser fan noise outside, and the vertical discharge fans carry the sound up and away from the surrounding area. Because of the simple design of the Intensity condensing unit, installation is quick and simple, and very little maintenance is required. nergy fficiency atings ( s) to 11.2!

STANA NIT FATS CABINT Galvanized steel with a durable powder paint finish. Stamped louvered panels offer 100% protection for the condenser coil. CMPSS The Scroll Compressor is hermetically sealed with internal overload protection and durable insulation on motor windings. The entire compressor is mounted on rubber grommets to reduce vibration and noise. CNNS CIL Constructed with copper tubes and aluminum fins mechanically bonded to the tubes for maximum heat transfer capabilities. BAS PAN Galvanized steel with powder paint finish. FIGANT CNNCTINS Field piping connections are made through a fixed panel. This allows removal of access panels after piping connections have been made. CANKCAS HATS Standard, all models. Prevents refrigerant migration to compressor(s). LW AMBINT CNTL A pressure sensitive fan cycling control to allow unit operation down to 0 F [ 17.8 C] is standard. SVIC VALVS Standard on liquid and suction lines. Allows outdoor section to be isolated from indoor coil. SVIC ACCSS Control box as well as the compressor and other refrigerant controls are accessible through access panels. Control box may be open without affecting the normal operation of the unit. Condenser fan motors are accessible by removing wire grilles. FILT I Standard (uninstalled) on all models. Helps ensure refrigerant cleanliness. TANSFM Step-down type, line to 24 volts. Provides control circuit voltage. CNTACT The contactor is an electrical switch which operates the compressor and condenser fans. HIGH PSS CNTL pens the contactor circuit on high refrigerant pressure; manual reset. LW PSS CNTL Stops compressor operation in the event of loss of refrigerant. CNNS FAN MT (irect rive) Ball bearing 1075 PM motors are mounted to minimize vibration and noise problems. These are permanent split capacitor types. TSTING All units are run tested at the factory prior to shipment. nits are shipped with a holding charge of nitrogen. XTNAL GAG PTS Allows pressures to be checked without removing access panel. CIL LVS Helps prevent damage to outdoor coils. TIM LAY Supplied on tandem compressor models to provide a delay between stages. QIPMNTGN Lug for field connection of ground wire. 3

16 IGGING FTP INSTALLATIN If rooftop installation is required, make certain that the building construction is adequate for the weight of the unit. (efer to physical data chart.) Before placing the unit on the roof, make certain that the nylon rigging slings are of sufficient length to maintain equilibrium of the unit when lifting. nder no circumstances should the unit be lifted by only one corner for rooftop installation. Illustration ST-A GNAL INSTALLATIN The condensing unit should be installed outdoors. It should be located as near as possible to the evaporator section to keep connecting refrigerant tubing lengths to a minimum. The unit must be installed to allow a free air flow to the condenser coils. If several units are installed adjacent to each other, care must be taken to avoid recirculation of air from one condenser to another. In all installations, adequate space must be provided for installation and servicing. SLAB INSTALLATIN Condensing units should be set on a solid level foundation. When installed at ground level, the unit should be placed on a cement slab. If the pad is formed at the installation site, do not pour the pad tight against the structure, otherwise vibration will be transmitted from the unit through the pad. The unit must not be connected to any duct work. o not locate unit under a roof drip; if necessary, install gutters, etc., to prevent water run-off from hitting the unit. To prevent air recirculation, it is recommended that the unit not be installed under an overhang, but if necessary allow a minimum of 60 inches [1524 mm] above the unit for air discharge. 16

When the room thermostat is set on Cool, Fan Auto, and the temperature is higher than the thermostat setting, the thermostat Y1 circuit closes and energizes the compressor contactor (CC) through the closed contacts of the high pressure and low pressure controls. to the crankcase heater (CCH) will be de-energized by the auxiliary contacts (AX-1) 2. Simultaneously, the G circuit provides power to the indoor blower motor circuit and starts indoor air circulation through the evaporator coil. 3. When the discharge pressure increases to 450 psig, the contacts on the low ambient control (LAC) will allow supply power to start the outdoor fan motors (F) which begin to pull air through the condenser coils. 4. The system will continue cooling operation, as long as the room thermostat Y1 circuit and all safety device contacts are closed. The low ambient control (LAC) will open and close, allowing the outdoor fans to maintain discharge pressure between 250 and 450 psig. 5. When the thermostat is satisfied, the Y1 circuit will open and de-energize the compressor contactor (CC), stopping compressor operation and closing the auxiliary contacts (AX-1), which energizes the crankcase heater (CCH). 6. The thermostat G circuit will stop blower operation. SQNC F PATIN AWL-125, 150, 180, 240, Two Stage 1. When the room thermostat is set on Cool, Fan Auto, and the temperature is higher than the thermostat setting, the thermostat Y1 circuit closes and energizes the number one compressor contactor (CC1) through the closed cooling relay () contacts. to the crankcase heater (CCH1) will be de-energized by the auxiliary contacts (AX-1). 2. Simultaneously, the G circuit provides power to the indoor blower motor circuit and starts indoor air circulation through the evaporator coil. 3. When the discharge pressure increases to 450 psig, the contacts on the low ambient control (LAC) will allow supply power to start the outdoor fan motors (F) which begin to pull air through the condenser coils. The system is now in first stage cooling, operating at near fifty percent of full load capacity. 4. If the temperature at the thermostat continues to increase, the thermostat Y2 circuit closes and after a 30 second delay, power passes through the time delay control (TC) and energizes the number two compressor contactor (CC2) through the second set of closed cooling relay () contacts. to the crankcase heater (CCH2) will be de-energized by the auxiliary contacts (AX-2) 5. The system will continue cooling at maximum capacity, as long as the room thermostat is demanding full load and all safety device contacts are closed. The low ambient control (LAC) will open and close, allowing the outdoor fans to maintain discharge pressure between 250 and 450 psig. 6. As the temperature at the thermostat drops enough to satisfy Y2, the circuit will open and de-energize the compressor contactor (CC2), stopping compressor operation and closing the auxiliary contacts (AX-2), which energizes the crankcase heater (CCH2). 5. When continued cooling satisfies the Y1 circuit, it will open and de-energize the compressor contactor (CC1), stopping compressor operation and closing the auxiliary contacts (AX-1), which energizes the crankcase heater (CCH1). 6. The thermostat G circuit will stop blower operation. 21
