INTRODUCTION
These instructions cover installation of 30HX liquid chill- ers with electronic controls and units with
IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with these instructions, this equip- ment may cause radio interference. The equipment has been tested and found to comply with the limits of a Class A computing device as de®ned by the FCC (Federal Communications Commission, U.S.A.) Regu- lations, Subpart J of Part 15, which are designed to provide reasonable protection against such interfer- ence when operated in a commercial environment.
INSTALLATION
Step 1 Ð Inspect Shipment Ð Inspect unit for dam- age upon arrival. If damage is found, ®le a claim with the shipping company right away. Do not store units in an area exposed to weather because of sensitive control mecha- nisms and electronic devices.
Locate unit indoors. When considering unit location, con- sult National Electrical Code (NEC, U.S.A.) and local code requirements. Allow sufficient space for wiring, piping, and service. Install unit in an area which will not be exposed to subfreezing weather. See Fig.
Allow the following clearances for service access:
Front . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 ft (914 mm) Rear . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 ft (914 mm)
Top | . . . . . . . . . . . . . . . 2 ft (610 mm) |
Ends | tube removal at one (either) end; |
| 3 ft (914 mm) at opposite end. |
Be sure surface beneath the unit is level and is capable of supporting the operating weight of the unit. See Fig. 5 and Tables 1A and 1B for unit operating weights. If necessary, add supporting structure (steel beams or reinforced concrete slabs) to ¯oor to transfer weight to nearest beams.
Step 2 Ð Rig and Place Unit
Rig unit from the top heat exchanger only. Rigging from the bottom heat exchanger will cause the unit to be lifted unsafely. Personal injury or damage to the unit may occur.
Do not remove unit from skid until unit is in its ®nal location. Rig from the rigging holes provided in the top heat exchanger. See Fig.
