NOTICE

THIS UNIT IS SHIPPED WITH A NITROGEN/HELIUM HOLDING CHARGE ONLY. UNIT MUST BE EVACUATED AND CHARGED PER INSTALLATION INSTRUCTIONS WITH REFRIGERANT LISTED ON SERIAL RATING PLATE.

NOTICE

UNITS SHIPPED WITH A HOLDING CHARGE ARE INTENDED FOR COMPONENT REPLACEMENT ONLY ON EXISTING SYSTEMS, AND NOT INTENDED FOR USE IN NEW SYSTEMS OR NEWLY CONSTRUCTED HOMES. EPA REGULATIONS PROHIBIT THE SALE OR DISTRIBUTION OF APPLIANCES PRE-CHARGED WITH THE REFRIGERANT R-22 IF THOSE APPLIANCES ARE MANUFACTURED AFTER JANUARY 1, 2010. COMPONENTS OF EXISTING R-22 SYSTEMS MAY BE REPAIRED AND/OR REPLACED.

NOTICE

UNITS MUST ONLY BE USED AS REPLACEMENT COMPONENTS FOR PRE-2010 INSTALLED SYSTEMS.

NOTE: Holding charge must be removed before brazing.

CAUTION

Prolonged operation at suction pressures less than 20 psig for more than 5 seconds will result in overheating of the scrolls and permanent damage to the scroll tips, drive bearings and internal seal.

1.Open service valves before attaching vacuum pump.

2.Connect the vacuum pump with 250 micron capability to the service valves.

3.Evacuate the system to 250 microns or less using suc- tion and liquid service valves. Using both valves is nec- essary as some compressors create a mechanical seal separating the sides of the system.

4.Close pump valve and hold vacuum for 10 minutes. Typi- cally pressure will rise during this period.

If the pressure rises to 1000 microns or less and remains steady the system is considered leak-free; proceed to startup.

If pressure rises above 1000 microns but holds steady below 2000 microns, moisture and/or noncondensibles may be present or the system may have a small leak. Return to step 2: If the same result is encountered check for leaks as previously indicated and repair as necessary then repeat evacuation.

If pressure rises above 2000 microns, a leak is present. Check for leaks as previously indicated and repair as nec- essary then repeat evacuation.

Electrical Connections

WARNING

HIGH VOLTAGE!

Disconnect ALL power before servicing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death due to electric shock. Wiring must conform with NEC or CEC and all local codes. Undersized wires could cause

poor equipment performance, equipment damage or fire.

WARNING

To avoid the risk of fire or equipment damage, use copper conductors.

NOTICE

UNITS WITH RECIPROCATING COMPRESSORS AND NON-BLEED TXV’S REQUIRE A HARD START KIT.

The condensing unit rating plate lists pertinent electrical data necessary for proper electrical service and overcurrent protec- tion. Wires should be sized to limit voltage drop to 2% (max.) from the main breaker or fuse panel to the condensing unit. Consult the NEC, CEC, and all local codes to determine the correct wire gauge and length.
