General Safety Information
General Safety Information
1. Installation and maintenance to be performed only by certified personnel who are familiar with this type of equipment.
2. Make sure that all field wiring conforms to the requirements of the equipment and all applicable national and local codes.
3. Avoid contact with sharp edges and coil surfaces. They are a potential injury hazard.
4. Make sure all power sources are disconnected before any service work is done on units.
Inspection
Responsibility should be assigned to a dependable individual at the job site to receive material. Each shipment should be carefully checked against the bill of lading. The shipping receipt should not be signed until all items listed on the bill of lading have been accounted for. Check carefully for concealed damage. Any shortage or damages should be reported to the delivering carrier. Damaged material becomes the delivering carrier’s responsibility and should not be returned to the manufacturer unless prior approval is given to do so. When uncrating, care should be taken to prevent damage. Heavy equipment should be left on its shipping base until it has been moved to the final location.

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. Where this essential requirement is not adhered to, it will result in higher head pressures, which cause poor operation and potential failure of equipment. Units must not be located in the vicinity of steam, hot air or fume exhausts. Corrosive atmospheres require custom designed condensers.
Another consideration which must be taken is that the unit should be mounted away from noise sensitive spaces and must have adequate support to avoid vibration and noise transmission into the building. Units should be mounted over corridors, utility areas, rest rooms and other auxiliary areas where high levels of sound are not an important factor. Sound and structural consultants should be retained for recommendations. (Refer to actual building plans for unit locations.)

Condensing Unit Rigging

Adequate rigging measures must be taken 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 compartment frame to assist.
Spreader bars may be used to protect unit from damage.

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. Install all refrigeration system components in accordance with applicable local and national codes and in conformance with good practice required for the proper operation of the system. The refrigerant pipe size should be selected from the tables in Refrigeration System Installation Manual, Part Number 25001201. The interconnecting pipe size is not necessarily the same size as the stub-out on the condensing unit or the evaporator.
The following procedures should be followed:
(a) Do not leave dehydrated compressors or filter-driers on condensing units open to the atmosphere any
longer than is absolutely necessary. (b) Use only refrigeration grade (ACR) copper tubing, properly sealed against contamination. (c) Suction lines should slope 1/4” per 10 feet towards the compressor (in direction of flow). (d) Suitable P-type oil traps should be located at the base of each suction riser to enhance oil return to
the compressor. (e) For desired method of superheat measurement, a pressure tap should be installed in each evaporator
suction line in the proximity of the expansion valve bulb. (f) When brazing refrigerant lines, an inert gas should be passed through the line at low pressure to
prevent scaling and oxidation inside the tubing. Dry nitrogen is preferred. (g) Use only a suitable silver solder alloy on suction and liquid lines. (h) Limit the soldering paste of flux to the minimum required to prevent contamination of the solder joint
internally. Flux only the male portion of the connection, never the female. After brazing, remove
excess flux. (i) Wrap expansion valves with wet rags during brazing to the liquid line.
CAUTION: If the temperature gets too high, these components may be damaged. Heat absorbing
compounds or wet rags must be used to protect the expansion valve when brazing to the refrigerant piping/line connections, and the suction line sensor must be removed per above instructions.
(j) Do not use “bull head” tees. This will cause oil return problems and can cause poor performance. (k) If isolation valves are installed at the evaporator, full port ball valves should be used.
