INSTALLATION INSTRUCTIONS A. Choosing Proper Location For Unit This unit is specifically designed for installation on the roof of an RV. When determining your cooling requirements, the following should be considered: ●● Size of RV; ●● Window area (increases heat gain); ●● Amount of insulation in walls and roof; ●● Geographical location where the RV will be used; ●● Personal comfort level required. 1.

INSTALLATION INSTRUCTIONS The opening created must be framed to provide adequate support and prevent air from being drawn from the roof cavity. Framing stock 3/4″ or more in thickness must be used. Remember to provide an entrance hole for power supplies, indoor temperature sensor (if applicable), thermostat communication cable, and furnace wires (if applicable) at the front of the opening. See (FIG. 7). a. This supply wire must be located in the front portion of the roof opening. b.
INSTALLATION INSTRUCTIONS 6. (CCC 2 system only) If an Energy Management System (load shed feature) is to be used with the control, two wires must be routed to the roof opening of the zone to be managed. The signal required for this function is normally an open relay contact. When the EMS calls for the compressor to shut off, the relay contacts should close. Make sure that at least 15″ of the EMS wire extends into the roof opening. 7.
INSTALLATION INSTRUCTIONS c. Optional Indoor Temperature Sensor I. Refer to the instructions provided with the indoor temperature sensor for details of installation. d. Thermostat Installation I. Carefully separate the thermostat base plate from the thermostat cover. Insert a small screw driver into the slot on bottom of thermostat and disengage the tab. See (FIG. 11). FIG. 11 cable (3 conductor cable) match the wire colors in the unit wire harness and the wire harness at the LCD SZ electronic control box.
INSTALLATION INSTRUCTIONS Lift and place the unit over the prepared opening using the gasket on the unit as a guide. See (FIG. 14). FIG. 16 Duct Divider FIG. 14 Ceiling Template Lift And Place Front ADB Do Not Slide 3. All models in this manual will use a four (4) bolt pattern for installing the ADB kit. H. 4. Place the electronic control box kit (if applicable) and the ADB kit inside the RV. These boxes contain mounting hardware for the unit and will be used inside the RV.
INSTALLATION INSTRUCTIONS FIG. 17 Models Using Electronic Control Kit Electrical Cord 4. Route the previously run 120 Vac power supply wire through the strain relief and into the junction box. Tighten strain relief making sure not to damage wires. Leave enough wire inside junction box to connect to unit 120 Vac wires. 5. Connect white to white; black to black; and green to green or bare copper wire using appropriate size wire connectors. 6.
INSTALLATION INSTRUCTIONS 5. Hold the clear strain relief cover with the bottom facing upward. See (FIG. 26).

Insert the freeze control sensor into the evaporator coil fins approximately 2″ to 3″ above the bottom of the coil fins and on the left side. See (FIG. 32). Bend fins over sensor to secure in place.
INSTALLATION INSTRUCTIONS Dip switches are in the "OFF" position when shipped from the factory except heat pump and factory installed heat strip models. On these models the appropriate dip switch, heat pump or heat strip, is in the "ON" position from the factory. e. Plug the indoor temperature sensor cable (if applicable) into the 2 pin matching connector protruding from the roof opening or the P4 (white) 2 pin matching connector in the electronic control box. f.
INSTALLATION INSTRUCTIONS g. Dehumidify - Dehumidify is not used on this unit. Leave in the "OFF" position. h. Gen Start selection - Leave in the "OFF" position. i. Install unit electrical box cover and out side plastic shroud or the electronic control box cover whichever applies. j. Repeat this procedure for each additional zone. 2. If your installation includes the optional electric heat kit, install it at this time. Follow the instructions with heat kit package for its installation procedure. 3.
INSTALLATION INSTRUCTIONS Mounting Bolt Pattern Table See (FIG. 40) Mounting Bolt Pattern Table See (FIG.
INSTALLATION INSTRUCTIONS 2. Install two (2) (supplied) sheet metal screws inside return air opening to secure ADB to ceiling template. See (FIG. 43). 3. Install eight (8) (supplied) wood screws inside the front, rear, and side doors to secure ADB to ceiling. See (FIG. 43). FIG. 43 6. Install return air vent grille into the ADB. Slide return air vent grille tab into slot in ADB and rotate up and snap in place. See (FIG. 45). FIG.
INSTALLATION INSTRUCTIONS 2. System Checkout a. Verify that all features of the installed system work. See CCC 2 thermostat Operating Instructions or User's Guide. Check the fan mode, cooling mode, heating mode (if applicable), and furnace mode (if applicable) operation. If features do not work, disconnect the 120 Vac and 12 Vdc power supplies and verify that all wiring is correct and that the correct dip switches have been set to the "ON" position. Q. FIG.
GENERAL INFORMATION A. Frost Formation On Cooling Coil C. Frost on a small portion of the coil is not unusual. Under certain conditions, ice may form on the evaporator coil. This is indicated by very cold output at very low air speed and the icing can be seen through the air inlet hole with the filter removed. If this should occur, inspect the filter and clean if dirty. Make sure air vents are open and not obstructed. Units have a greater tendency to frost when the outside temperature is relatively low.
