SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service mechanics should install, start up, and service this equipment.

Untrained personnel can perform basic maintenance func- tions, such as cleaning coils. All other operations should be performed by trained service personnel.

When working on the equipment, observe precautions in the literature, and on tags, stickers, and labels attached to the equipment and any other safety precautions that may apply.

•Follow all safety codes.

•Wear safety glasses and work gloves.

•Use care in handling, rigging, and setting bulky equipment.

WARNING

Open all remote disconnects before servicing this equip- ment. Failure to do so could result in personal injury from electric shock.

CAUTION

Puron refrigerant (R-410A) systems operate at higher pres- sures than standard R-22 systems. Do not use R-22 service equipment or components on Puron refrigerant equipment. If service equipment is not rated for Puron refrigerant, equipment damage or personal injury may result.

INSTALLATION

Step 1 — Inspect Shipment — Inspect unit for dam- age upon arrival. If damage is found, immediately file a claim with the shipping company. Verify proper unit delivery by checking unit nameplate data and the model number nomen- clature shown in Fig. 1. See Tables 1-4 for unit physical data.

Step 2 — Rig and Place Unit — All units are de- signed for overhead rigging, and it is important that this meth- od be used. Lifting holes are provided in the frame base rails. It is recommended to use shackles in the lifting holes (see rigging label on the unit and Table 5, and Fig. 2 and 3 for rigging weights and center of gravity). All panels must be in place when rigging.

IMPORTANT: To maintain unit stability while lifting, use 4 cables, chains or straps of equal length. Attach one end of each cable to shackle attachment point and the other end of each cable to the overhead rigging point.

Use spreader bars or frame to keep the cables, chains, and straps clear of the unit sides. Leave standard coil protection packaging in place during rigging to provide protection to coils. Remove and discard all coil protection after rigging ca- bles are detached.

CAUTION

All panels must be in place when rigging. Failure to com- ply could result in equipment damage.

CAUTION

For unit sizes 025 to 060 when handling with a forklift, handle only through fork pocket holes. Failure to follow this caution could result in equipment damage or personal injury.

CAUTION

For unit sizes 070 to 100, do not forklift the unit unless unit is attached to a skid designed for forklifting. Failure to fol- low this caution could result in equipment damage or per- sonal injury.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
