SAFETY CONSIDERATIONS
Installation, start-up and servicing of this equipment
can be hazardous due to system pressures, electrical
components and equipment location.
Only trained, qualified installation and service per­
sonnel should install, start-up or service this equipment.
When working on this equipment, observe precautions
in the literature, tags, stickers and labels attached to the
equipment and any other safety precautions that apply.

INSTALLATION
Step 1 — Prepare for Installation
PREPARE EQUIPMENT ROOM — Locate compres­
sor or condensing unit in a well-ventilated area. If natural
ventilation is inadequate, provide forced ventilation
through ductwork. Check applicable code requirements.
Provide freeze-up protection for water-cooled con­
densers, water lines and accessories if freezing tempera­
tures can occur during winter shutdown periods.
Provide sufficient clearance for removal of compressor
cylinder heads and valve plates. Allow space on the oil
pump end for crankshaft removal as follows:
5F20, 30, 40, and 60 compressors...............................20in.
5H40, 46, 60, and 66 compressors.............................. 20 in.
5H80, 86, 120, and 126 compressors..........................30 in.
Provide space equal to condenser length for tube
removal and cleaning.
Step 2 — Receive Machine (Fig. 1 through 8)
BEFORE UNLOADING — Check unit nameplates
against model and serial numbers recorded in job speci­
fications. Check all items against shipping list, and
examine items carefully for any shipping damage. If
damage is found or any major component has torn loose
from its anchorage, have transportation inspectors
examine it before unloading. File claim immediately with
shipping company for any loss or damage.
