Verify that all parts ordered were received as specified and that the unit is the

 

correct size and voltage necessary to fulfill your environmental control

 

needs. Report any damage discovered to the freight carrier. If necessary,

 

contact the APC field service department for help in repairing or replacing

 

damaged parts. While APC is not responsible for damage incurred in transit,

 

we want to make sure that you have no undue delays in your system start-up.

Rigging

The unit is manufactured with a formed steel frame for maximum strength

 

and unit integrity. However, as with all electrical and mechanical equipment,

 

you must take care with proper rigging of your unit.

 

When using a forklift to move the unit, use the shipping skid to protect the

 

bottom of the unit. When using chains, cables or rope to lift the unit, use

 

spreader bars to prevent damage to the finished panel.

Floorstand

Install a threaded pedestal into each leg of the floorstand. Use the washer and

 

nut on each panel to tighten against the floorstand leg.

Utility connections

All connections are made through the bottom left of the unit (the left side of

 

upflow discharge units) for ease of service connections. Refer to the

 

installation manual for pipe sizes and specific locations for your unit.

Power unit

The AFX unit uses 3-phase power for operation. Bring the service cable

 

through the bottom left of the unit and through the bulkhead hole into the

 

electrical box to the circuit breaker provided on he left side of the electrical

 

box. The ground lug is located near the 3-phase high-voltage connector. THE

 

UNIT MUST BE UTILITY GROUNDED OR THE WARRANTY IS

 

VOID.

Humidifier

The humidifier inlet connection is in the bottom of the mechanical section. A

connections

1/4" compression connection is supplied with the unit.

Condensate drain

Condensate from the evaporator pan and discharge from the humidifier

 

flushing system drain through a 7/8" ID drain trap in the bottom of the unit.

Water supply to

1. The humidifier fill valve orifice is sized for supply water pressure from

humidifier

30 PSIG (210 kPa) to 85 PSIG (590 kPa).

 

2. For cases above 90 PSIG (630 kPa), install a pressure-reducing valve in

 

the water feed line to the unit.

 

3. With extremely dirty or muddy water sources, proper filtration is

 

required on the units incoming water line.

 

4. DO NOT use softened water with the humidifier. Softened water is too

 

conductive.

 

5. DO NOT use completely demineralized water with the humidifier. The

 

minerals allow the electrode principle to work.

 

6. DO NOT use a hot water source. Doing so will cause deposits that will

 

eventually block the fill valve orifices.
