HANDLING THE UNIT — To avoid overturning the unit,
the angle of inclination should not be more than 15 degrees
when carrying the unit
.
LIFTING UNIT WITH CABLES — Make sure the lifting
cables can withstand the weight of the unit. Use 2 cables.
Make sure each cable is at least 26.3 feet long to avoid
excess tension and force on the surfaces of the unit. To
avoid damage while lifting the unit, do not remove the
original packaging or unscrew from its original pallet.
Connect lifting cables diagonally as shown in Fig. 5 below.
Note the center of gravity in Fig. 5 below, which results
from the weight of the compressor and other components
located within the right-end section of the unit.
CONCRETE BASE REQUIREMENTS
• The unit’s base must be made of solid concrete.
• Ensure that the base is level and that the weight of the
unit is distributed evenly. See Fig. 6 below for reference.
Fig. 6 —Concrete Base
• Create an outlet near the base for drainage. Refer to
Fig. 7 below for main drain connection.
Fig. 7 —Drain Connections
• Ensure the roof can handle the unit weight if mounted on
the roof.
Step 3 — Connect Refrigerant Piping and
Wiring —
Refrigerant pipe connections are made on the side
of the unit. Remove the L-shaped metal plate, and route piping
through the exposed opening. Route power and control wiring
through the two separate, adjacent knockouts. See Fig. 8 for
details.
INSULATION — Liquid lines and suction lines must be
insulated separately. Closed-cell insulation with fire-retardant
properties is recommended.
• For copper pipes less than
1
/
2
inch. OD, recommended
insulation thickness is
1
/
2
inch.
• For copper pipes equal to or greater than
5
/
8
inch. OD,
the recommended insulation thickness is
3
/
4
inch.
