2-4. Installation Instructions
a.
Due to conditions which may vary at the worksite detailed installation instructions are not provided with this
manual. Steps described in this paragraph are minimum installation requirements necessary for efficient operation of the
air conditioner. Adaptations should be made to conform with ductwork existing at the installation site. See figure 1-10 for
installation and base plan space requirements.
(1)
Using the lifting method described in paragraph 2-2c (1) or (2), position the airconditioner in the appropriate
location on the shelter (or trailer) so that the conditioned air outlet and recalculating air inlet ports line up with the provided
ducting at the installation site.
(2)
Make sure that unobstructed outdoor ambient air flow is available at the condenser air inlet, condenser air
discharge, and vent air inlet ports.
(3)
Secure the air conditioner to its mounting base using the eight mounting holes provided in the base of the air
conditioner (fig. 1-10). When necessary, ruse shilms to level air conditioner.
Note. An air tight seal must be maintained between external ducting and the air conditioner for efficient operation.
Make certain that the ducting and air conditioner are properly aligned after leveling air conditioner.
Mount the remote control box assembly on a wall or panel at a convenient level for operation.
Note
Remove electrical tray assembly panel (para 3-25) and store for future use.
(5)
