Page 6: Condensing Unit Placement
Condensing Unit Placement Space and Location Requirements The most important consideration which must be taken into account when deciding upon the location of air- cooled equipment is the provision for a supply of ambient air to the condenser, and removal of heated air from the condensing unit or remote condenser area. -
Page 7: Condensing Unit Rigging
Condensing Unit Rigging Figure 3. Condensing Unit Rigging Adequate rigging measures must be tak- en to support unit weight and to protect the unit from damage during unloading and placement process. Rigging holes have been provided in legs and under the unit compressor compart- ment frame to assist. -
Page 8: Refrigeration Piping And Line Sizing
Refrigeration Piping And Line Sizing Refrigeration Piping And Line Sizing The system as supplied by Heatcraft Refrigeration Products, was thoroughly cleaned and dehydrated at the factory. Foreign matter may enter the system by way of the evaporator to condensing unit piping. Therefore, care must be used during installation of the piping to prevent entrance of foreign matter. - Page 9 Suction Lines NOTE: If the suction line must rise to the point higher than the suction connection on the evaporator, a suction line trap at the outlet of the evaporator must be provided. Horizontal suction lines should slope away from the evaporator toward the compressor at the rate of 1/4’ per 10 feet for good oil return.
- Page 10 Figure 6. Example of Pipe Support Normally, any straight run of tubing must be supported in at least two locations near each end of the run. Long runs require additional supports. The refrigerant lines should be supported and fastened properly. As a guide, 3/8 to 7/8 should be supported every 5 feet, 1-1/8 and 1-3/8 every 7 feet;...

Page 11: Leak Detection And Evacuation
Leak Detection And Evacuation Leak Testing After all lines are connected, the entire system must be leak tested. The complete system should be pressurized to not more than 150 PSIG with refrigerant and dry nitrogen. The use of an electronic type of leak detector is highly recommended because of its greater sensitivity to small leaks. -
Page 12: Field Wiring
Field Wiring WARNING: All wiring must be done in accordance with applicable codes and local ordinances. The field wiring should enter the areas as provided on the unit. The wiring diagram for each unit is located on the inside of the electrical panel door. All field wiring should be done in a professional manner and in accordance with all governing codes. -
Page 13: Refrigeration Charging
Refrigeration Charging 1. Install a liquid line drier in the refrigerant supply line between the service gauge and the liquid service port of the receiver. This extra drier will insure that all refrigerant supplied to the system is clean and dry. 2. -
Page 14: Operational Checkout
After the system has been charged and has operated for at least 2 hours at normal operating conditions without any indication of malfunction, it should be allowed to operate overnight on automatic controls. Then a thorough re- check of the entire system operation should be made as follows: (a) Check compressor discharge and suction pressures. -
Page 15: Preventive Maintenance
Preventive Maintenance Routine preventive maintenance of any mechanical equipment is critical to its long term reliability. During normal operation all equipment will experience some deterioration during its lifetime caused by wear and evironmental influences. For that reason, regularly scheduled maintenance of your refrigeration equipment is required in order to keep it operating to its maximum efficiency while avoiding potentially costly repairs of a premature failure due to equipment neglect. - Page 16 Preventive Maintenance...
