4-5. INSTALLATION INSTRUCTIONS. - continued
(e) Determine where control module is to be located. Note that sensing bulb controls thermostatic
action of TEMPERATURE SELECTOR. It should be mounted where a true room or enclosure
temperature will be indicated. Do not place near heat or cool producing items. False temperature
control would result.
(f)
Secure control module and sensing bulb.
(g) The receptacle and plug needed to fabricate the interconnecting cable are provided with unit.
Determine length of wire needed to connect plug and receptacle between unit and control
module.
(h) See remote control cable diagram, figure 4-4, sheet 7 and fabricate the interconnecting cable for
either the F9000H-3SA or F9000H-1SA. This cable will connect between P2A/B and J2A/B.
(i)
Connect cable.
(j)
(3) No other preparation is necessary if the air conditioner is to be installed by the typical exterior wall
opening method and operated as a self-contained unit.
b. Installation Instructions. Appropriate alterations to the facility to accommodate the selected method of
installation must be completed before actual installation of the air conditioner.
(1) Shelter/Enclosure Preparation. The following information describes a typical through the wall type
installation. You may want to alter these instructions to suit your specific application. See figure 4-6
for a through the wall installation that allows removal of the front and rear top panels for service with the
unit installed.
(a) Determine best location.
(b) Make cutout in wall slightly larger than overall dimension of air conditioner.
(c) Fabricate a mounting platform or braces. Provide mounting holes to match holes in bottom of air
(2) Lift air conditioner into position. Use adequate equipment or four people to lift the unit into position.
(3) Secure unit to mounting platform or braces with four sets of mounting hardware provided with unit.
See figure 4-1, sheet 3, for cross section view of bottom mounting holes and hardware.
Death on contact may result if personnel fail to observe safety precautions.
For safe operation, connect a 10 AWG (minimum) ground wire to the air conditioner
external ground. Make sure that shelter is properly grounded.
(4) Connect a 10 AWG (minimum) ground wire from shelter ground to air conditioner external ground.
The air conditioner external ground connection point is located on front left side of control module.
(5) Fill in and seal area around the air conditioner to prevent loss of conditioned air. Flexible plastic foam
and pressure sensitive tape may be used.
