RECEIVING THE AIR CONDITIONER

Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents,

scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill.

Damage should be brought to the attention of the delivering carrier -- NOT to Pentair Equipment Protection --

within 15 days of delivery. Save the carton and packing material and request an inspection. Then file a claim with

the delivering carrier.

Pentair Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any

way possible.

HANDLING AND TESTING THE AIR CONDITIONER

If the air conditioner has been in a horizontal position, be certain it is placed in an upright, vertical or mounting

position for a minimum of five (5) minutes before operating.

Do not attempt to operate the air conditioner while it is horizontal

or on its side, back or front. The refrigeration compressor is filled

with lubricating oil. This will cause permanent damage to the air

conditioner and also voids the warranty.

CAUTION

TEST FOR FUNCTIONALITY MOUNTING THE AIR CONDITIONER TO THE ENCLOSURE.BEFORE

Refer to the nameplate for proper electrical current requirements, and then wire the unit to a properly grounded

power supply using copper conductors only. Power supply wiring should be restrained after field installation to

ensure no contact with internal fan. Minimum circuit ampacity should be at least 125% of the amperage shown on

the unit nameplate. No other equipment should be connected to this circuit to prevent overloading

Immediately after applying power, the evaporator blower (enclosure air) should start running. Operate the

air conditioner with the compressor running for five (5) to ten (10) minutes. You will need to set the cooling

thermostat or controller setpoint below the ambient temperature to operate the compressor.

Condenser air temperatures should be warmer than normal room temperatures within a few minutes after the

condenser impellers start.

See Sequence of Operation on page 4 for specifics on how the unit operates when powered up.

HOW TO READ MODEL NUMBERS

G28 06 G1504 6

12345

1. Identifies the type/family of air conditioner and the approximate height (i.e. G28 = Global family

about 28 inch high).

2. This is the air conditioner’s listed capacity in BTU/Hr. at rated conditions. (i.e. 06=6,000 BTU/Hr. at

131/131 F)

3. 1 = 115 Volt, 2 = 230 Volt, 4 = 460 Volt.

4. 6 = 50/60 Hz or 60 Hz only.

5. Unique set of numbers for each air conditioner which identifies the accessories on a model.
