Page 4: Inspection
1.1 INSPECTION As soon as a unit is received, it should be inspected for possible damage during transit. If damage is evident, the extent of the damage should be noted on the carrier's delivery receipt. A separate request for inspection by the carrier's agent should be made in writing. - Page 5 AIR DISCHARGE: ALLOW 60” MINIMUM CLEARANCE.

3.0 UNIT INSTALLATION 3.1 LOCATION Before starting the installation, select and check the suitability of the location for both the indoor and outdoor unit. Observe all limitations and clearance requirements. The outdoor unit must have sufficient clearance for air entrance to the condenser coil, for air discharge and for service access. -
Page 7: Precautions During Line Installation
CAUTION This system uses R410A refrigerant which operates at higher pressure than R-22. No other refrigerant may be used in this system. Gauge sets, hoses, refrigerant containers, and recovery system must be designed to handle R410A. If you are unsure, consult the equipment manufacturer. The outdoor unit must be connected to the indoor coil using field supplied refrigerant grade copper tubing that is internally clean and dry. -

Page 9: Precautions During Brazing Service Valve
CAUTION Dry nitrogen should always be supplied through the tubing while it is being brazed, because the temperature required is high enough to cause oxidation of the copper unless an inert atmosphere is provide. The flow of dry nitrogen should continue until the joint has cooled. Always use a pressure regulator and safety valve to insure that only low pressure dry nitrogen is introduced into the tubing.Only a small flow is necessary to displace air and prevent oxidation. -

Page 14: Evacuation
5.0 EVACUATION It will be necessary to evacuate the system to 500 microns or less. If a leak is suspected, leak test with dry nitrogen to locate the leak. Repair the leak and test again. To verify that the system has no leaks, simply close the valve to the vacuum pump suction to isolate the pump and hold the system under vacuum. - Page 15 TABLE 2: SUCTION LINE LENGTH/SIZE VS CAPACITY MULTIPLIER(R410A) Unit Size 1 1/2 Ton 2 Ton 2 1/2 Ton 3 Ton 3 1/2 Ton 4 Ton 5 Ton Suction Line Connection Size 3/4" I.D. 3/4" I.D. 3/4" I.D. 3/4" I.D. 3/4" I.D. 7/8"...

9 .1 CHARGING BY LI Q UID PRESSURE The liquid pressure method is used for charging systems in the cooling and heating mode. The service port on the liquid (small valve) and suction (large valve) is used for this purpose. Verify that the outdoor unit is running and the indoor air mover is delivering the maximum airflow for this system size. -
