These guidelines come from experiences people have had in actual applications. When sizing the generator, the total power usage of your RV must be considered. Keep in mind generators lose power at high altitudes and from lack of maintenance. *** CIRCUIT PROTECTION: Time Delay Fuse or Circuit Breaker Required. B. Roof Requirements ● A 14-1/4″ x 14-1/4″ (±1/8″) square opening (hereinafter referred to as “roof opening”) is required for install ing this unit. This opening is part of the return air system of the unit and must be finished in accordance with NFPA 1192. ● Roof construction with rafters/joists support frames on a minimum of 16 inch centers. ● Minimum of 2 inches and maximum of 4 inches distance between roof to ceiling of RV. 4

INSTALLATION PROCEDUREA. Choosing Proper Location For Unit This unit is specifically designed for installation on the roof of a recreational vehicle (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 FIG. 2 20″ 22″ 2-1/2″ Dimensions Are Nominal Air Distribution

used; ● Personal comfort level required. 1. For one unit installation: The unit should be mounted slightly forward of center (front to back) 2-7/8″ Box Perimeter Roof Opening Center Line

and centered from side to side. 20″ Of Opening Front

2. For two unit installations: Install one unit 1/3 and one unit 2/3’s from front of RV and centered from side to side. It is preferred that the unit be installed on a relatively flat and level roof section measured with the RV parked on a level surface, but up to a 8° tilt is acceptable. 3. After Location Has Been Selected: a. Check for obstructions in the area where unit will be installed. See (FIG. 1). FIG. 1 9-1/2″ 40″ 29″ Keep These Areas 3-7/8″ 3-7/8″ 2-7/8″ 22″ Dimensions Are Nominal B. Roof Preparation 1.  FIRE OR ELECTRICAL SHOCK HAZARD. Verify there are no obstacles inside RV roof and/or walls (wires, pipes, etc.). Shut OFF gas supply, disconnect 120 Vac power from RV, and disconnect positive (+) 12 Vdc terminal from supply battery BEFORE drilling or cutting into RV. Failure to obey these warnings could result in death or serious injury. Opening Requirements - Before preparing

12″ 4″ Center Line Of Unit Free Of Obstructions Roof Opening Front 4″ the ceiling opening, the type of system op tions MUST be decided upon. Read all of the following instructions before beginning the installation. Carefully mark and cut the required roof open ing. See section, "B. Roof Requirements" on page (4).

Dimensions Are Nominal b. Maintain structural integrity. Otherwise damage to product and/or RV could occur. The roof must be designed to support 130 pounds when the RV is in motion. Normally a 200 lb. static load design will meet this re quirement. c. Check inside the RV for air distribution box obstructions (i.e. door openings, room di viders, curtains, ceiling fixtures, etc.) See (FIG. 2). 5 2. Using the roof opening as a guide, cut the match ing hole in the ceiling. 3. Maintain structural integrity. Oth erwise damage to product and/or RV could oc cur.  NEVER create a low spot on RV roof. Otherwise, water will pool and could cause a leak. 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, 3 conductor cable, and furnace wiring (if applica ble). See (FIG. 3). INSTALLATION PROCEDURE FIG. 3 4. If system includes a gas furnace, route two 18 gauge thermostat wires from the furnace to the roof opening of the unit that will control it. If more than one furnace is to be used, route the second set of thermostat wires to the second unit. Make sure that 15″ of wire extends into the opening.

3/4″ Min. Leave Access For Power Supply Wiring Frame Opening So It Won't Collapse When Bolting Down Unit 15″ Min. At Front Of Opening portant to ensure that it will provide a comfortable RV temperature. Observe the following rules when selecting a location: 1. Locate the thermostat 54″ above the floor. 2. Install the thermostat on a partition, not on an outside wall. 3. NEVER expose the thermostat to direct heat from lamps, sun or other heat producing items. 4. Avoid locations close to doors that lead outside, windows or adjoining outside walls. 5. Avoid locations close to supply registers and the air from them.

C. Wiring Requirements 1. Route a copper, with ground, 120 Vac supply wire from the time delay fuse or circuit breaker box to the roof opening. The proper size wire can be determined from chart on page 4. a. This supply wire must be located in the front portion of the roof opening. b. The power MUST be on an appropriately sized separate time delay fuse or circuit breaker. The proper size protection can be determined from the chart on page 4. c. Make sure that at least 15″ of supply wire extends into the roof opening. This insures an easy connection at the junction box. d. Protect the wire where it passes into the opening with approved method. 2. Route a dedicated 12 Vdc supply wire (18-22 AWG) from the RV’s converter (filtered side) or battery to the roof opening. a. This supply wire must be located in the front portion of the roof opening. b. Make sure that at least 15″ of supply wire extends into the roof opening. 3. Route a 3 conductor cable, 18 to 22 AWG, from the roof opening to the Single Zone LCD (here inafter referred to as SZLCD) thermostat mount ing location. Make sure that at least 15″ of the wire extends into the roof opening and 6″ extend from the wall at the thermostat mounting loca tion. See "D. Choosing Thermostat Location" on page (6). 6. When multiple single zone thermostats are be ing utilized, each individual thermostat MUST be installed in the room that the air conditioner is responsible for cooling to prevent air condition ers from attempting to turn on at the same time and overloading the breaker. E. Thermostat and Thermostat Cable Installation 1. SZLCD Thermostat Wire colors listed for the three conductor cable match the wire colors in the harness at the SZLCD electronic control box. Avail able wire colors may vary. a. Remove the cover from the SZLCD thermo stat. Depress tab on bottom of thermostat and separate it from the base. b. Insert the previously run three (3) conductor cable through the hole in the base assembly. c. Cut back the outer cable shield approxi mately 3 inches and strip 1/4″ insulation from each wire. d. Mount the thermostat level on the wall using the screws provided. e. Make the following connections to the ther mostat. See (FIG. 4).
