II. AIR CONDITIONING SIZING The ability of an air conditioner to cool down a vehicle or maintain a consumer desired temperature is dependent on the heat gain of the vehicle. The physical size, the window area, the quality and amount of insulation, the exposure to sunlight, the number of people using the vehicle and the outside temperature, may increase the heat gain such that the capacity of the air conditioner is exceeded. to 19 degrees C).
2. 3. B. IMPORTANT – Allow 600mm of supply wiring through the support frame (working length). It may be necessary to seal some of the old roof vent mounting screw holes which may fall outside of the air conditioner basepan gasket. After the support frame is installed, seal all gaps between the frame and both the roof exterior and the interior ceiling of the vehicle (cavity walls). Additionally, seal the gap around the electrical supply wiring. Examine the roof opening.
If the roof of the vehicle is sloped (not level) such that the air conditioner cannot be mounted within the maximum allowable degree deviations, an exterior leveling shim will need to be added to make the air conditioner level. A typical front to back leveling shim is shown in Figure 3. Once the air conditioner has been leveled, some additional shimming may be required above the interior ceiling assembly.
FIGURE 4 VI. ELECTRICAL WIRING ROUTING 240 VAC WIRING DANGER Following high voltage wiring specifications and all local and national electrical codes, route the roof top unit 240 VAC supply wiring from its power source to the wirebox. WHEN USING NON-METALLIC SHEATH CABLES (ROMEX, ETC.), STRIP SHEATH BACK TO EXPOSE 100-150mm OF THE SUPPLY LEADS. STRIP THE INDIVIDUAL WIRE LEAD ENDS FOR WIRE CONNECTION (ABOUT 19mm BARE WIRE). INSERT THE SUPPLY WIRES INTO THE ELECTRICAL CONNECTOR CLAMP.
IN NO CASE SHOULD CLAMPING OR PINCHING ACTION BE APPLIED TO THE INDIVIDUAL SUPPLY LEADS (NEUTRAL AND “HOT” WIRES). THIS COULD RESULT IN PINCHING THROUGH THE PLASTIC WIRE INSULATION AND CAUSE SHORTING OR “HOT” WIRES TO GROUND (SHOCK HAZARD). THE CLAMP IS INTENDED FOR STRAIN RELIEF OF THE WIRES. SLIGHT PRESSURE IS USUALLY SUFFICIENT TO ACCOMPLISH THIS.
K. Pull the fabric duct material through ceiling assembly discharge opening. Peel the release liner from the adhesive strip around the discharge opening. Press the fabric duct material firmly in place around opening. Cut off excess fabric on inside of ceiling assembly chute with a box knife taking care not to tear the fabric beyond the adhesive strip.
FIGURE 9 VIII. COMPLETING THE INSTALLATION (9000 SERIES) A. Make sure the non-allergenic filters are properly positioned in the ceiling grille. B. Install the ceiling grille by positioning on the bottom of the shroud and engaging the two 1/4 turn fasteners. C. Turn the selector switch to OFF position. D. Turn ON the power supply to the roof top air conditioner. E.
