Installation Instructions for Remote Condenser

REMOTE CONDENSING UNIT

Refrigeration line installation

Refrigeration line installation: 5/8" suction / 3/8" liquid line (1010, 1410)

3.1

CAUTION

• The installer of the refrigeration line set must be USA Government Environmental Protection Agency (EPA)

certied in proper refrigeration handling and service procedures

• A qualied person must perform all roof or wall penetration

• Do not form unwanted traps in refrigeration lines. A service loop is not considered an oil trap.

• Never coil excess refrigeration tubing

• The compressor oil rapidly absorbs moisture. Minimize the exposure of the refrigeration system by not releasing

the condenser unit or evaporator unit holding charge until all line connections are nished and the system is

ready for evacuation.

WARNING

• This unit contains an R404A holding charge

1. Make and connect line set run from the condensing unit to the evaporator unit with all

specications found in the installation specications section. Do not overheat shut off valves on

the condenser unit or evaporator unit.

Note: Insulate entire suction line (not the liquid line) including shut off valves to prevent

condensation.

2. Leak check eld joints via the evaporator unit service valves.

3. Evacuate line set via the evaporator unit service valves.

5. Open the liquid line service valve and suction line service valve on the evaporator unit and

condenser unit.

6. Open the liquid line valve on the receiver, then the suction line valve on the compressor unit.

7. Liquid charge unit through liquid line shut off valve on the evaporator unit or receiver valve on

the condensing unit.

8. Isolate the refrigerant tank from high pressure side on the system.

9. Turn on power to condensing unit and evaporator unit.

10. Complete system charge through low pressure side.
