3-12. INSTALLATION INSTRUCTIONS . All alterations to the shelter or facility where the air conditioner is to be installed
should be complete before installation of air conditioner.
WARNING
Do not allow the unit to swing while suspended from a lifting device. Failure to
observe this warning may result in injury to personnel and damage to the
equipment.
CAUTION
Use care in handling to avoid damage to the air conditioner. If an overhead lifting
device must be used, use an appropriate sling so that the weight of the unit is
supported by the base of the shipping container.
a. Attach an overhead hoist, sling, and spreader bar to lifting fittings on each side of cabinet.
b. Move air conditioner into position and align mounting holes.
c. Secure unit with appropriate mounting hardware.
d. Seal all openings around cutouts for air conditioned air and water tight. Use gasket, caulking, or other suitable
material (Item 19, Appendix E).
e. The air conditioner is provided with a drain hole in the lower left rear corner of the housing. If plug has not been
removed from this drain opening, remove this plug now to allow for drainage of condensate water. If water from this drain
will be objectionable or create a hazard, external overboard drains can be connected. Install pipe to tube fitting (Item 1,
Appendix D) to connect base drains. Any type of hose or tubing may be used as a drain line. The drain line should lead
to an appropriate facility drain, storm sewer, dry sump, or an acceptable outside area. Be sure the entire length of the
drain line is lower than the base to ensure gravity drainage.
f. (Refer to Figure 3-5). Attach a ground cable to ground screw (1) on front of unit.
