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 functions, 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 equipment. Failure to do so could result in personal injury from electric shock.

GEMINI™ SELECT

with PURON® Refrigerant (R-410A)

50/60 Hz

CAUTION

Puron refrigerant (R-410A) systems operate at higher pressures 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 —

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 nomenclature 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 method 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 cables are detached.

CAUTION

All panels must be in place when rigging. Failure to comply 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 follow this caution could result in equipment damage or personal injury.

Inspect unit for dam-

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

sists of coil protection only. Skids are not provided. If overhead rigging is not available at the jobsite, place the unit on a skid or pad before dragging or rolling. When rolling, use a minimum of 3 rollers. When dragging, pull the pad or skid. Do not apply force to the unit. When in final position, raise from above to lift unit off the pad or skid.

EXPORT UNITS — All export units are mounted on skids with vertical coil protection. Leave the unit on the skid until it is in final position. While on the skid, the unit can be rolled or skidded. Apply force to the skid, not to the unit. Use a minimum of 3 rollers when rolling. When in final position, raise from above to remove the skid.

PLACING UNITS — When considering location of the unit, be sure to consult National Electrical Code (NEC, U.S.A.) and local code requirements. Allow sufficient space for airflow, wiring, piping, and service. The placement area must be level and strong enough to support the operating weight of the unit. (See Table 5.) When unit is in proper location, use of mounting holes in base rails is recommended for securing unit to supporting structure. For mounting unit on vibration isolators,

4 x 24 in. perimeter support ASTM “C” channels between unit and the isolators are recommended with a minimum of 4 channels per unit. Fasteners for mounting unit are field supplied. See Fig. 4.

Refer to Fig. 5-8 for airflow clearances. Recommended minimum clearances are 6 ft (1829 mm) for unrestricted airflow and service on sides of unit, 4 ft (1219 mm) on ends, and unrestricted clear air space above the unit. Provide ample space to connect liquid and suction lines to indoor unit. For multiple units, allow 10 ft (3048 mm) separation between airflow surfaces. If walls surround the unit, wall height should not exceed the top of the unit fan discharge. Installation in a pit is not recommended.

IMPORTANT: Be sure to mount unit level to ensure

proper oil return to compressors.

Refer to Fig. 9 for outdoor fan and compressor layout.

Refer to Fig. 10 and 11 for unit piping installation. See Table 6 for refrigerant specialties part numbers.
