| 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 |
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 |
| 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 |
| 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 |
| 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. |
