Step 1: Stick Sponge (Sealing Strip) and Sponge on the Outdoor Unit

1. Before sticking, clean up the sundries at the sticking position (as shown in Figure 1) of the chassis of the outdoor unit to ensure that the sticking position is clean;
2. Take out one piece of sponge (sealing strip) and one piece of sponge from the accessories, and tear off the paper on the glue surface and align at the edge of the position as shown in Figure 1 to stick the sponge. If the sponge (sealing strip) is damaged or not stuck on the proper position, you must replace it with a new one and stick it properly;
3. Check whether the sponge (sealing strip) and the sponge are tightly adhered, and ensure that they will not fall off.

Step 2: Selecting an Installation Location & Installing the Roof Top Air Conditioner

Your air conditioner has been designed for use in recreational vehicles. Check the roof of the vehicle to determine if it can support both the roof top unit and the ceiling assembly without additional support. Make sure the interior ceiling mounting area will not interfere with existing structures.

Once the location for your air conditioner has been determined. A reinforced and framed roof. Hole must be cut (if there is no hole, please refer to CASE B) or you may use existing vent holes (See CASE A).

Case A: If a roof vent is already present in the desired mounting location for the air conditioner the following steps must be performed:

1. Remove all screws which secure the roof vent to the vehicle. Remove the vent and any additional trim. Carefully remove all chalking from around the opening so the surface is clear.
2. 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.
3. Examine the roof opening size, if the opening is small than (14-1/4”)x(14-1/4”), the opening must be enlarged.

Case B: If a roof vent opening is not used,a new opening(see figure 1-1)will be cut into the vehicle roof. A matching opening will also have to be cut into the interior vehicle ceiling,be careful when cutting the ceiling opening because if the ceiling opening is carpeted,snagging could occur. After the opening in the roof and interior ceiling are the correct size,a framed support structure must be placed between the exterior roof top and interior ceiling.The reinforced framed structure must follow the following guidelines:

1. It must be capable of supporting both the weight of the roof top air conditioner and the interior ceiling assembly.
2. It must be capable of holding the roof outer surface and interior ceiling apart and supporting them, so that when the roof top air conditioner and ceiling assembly are bolted together,no collapsing occurs. A typical support frame is shown in Figure 1-1 .
3. There must be an opening through the frame for the power supply wiring.Route the supply wiring through the frame at the same time the support frame is being installed.

Caution

The roof top air conditioner must be mounted on a level plane from front to rear and side to side when the vehicle is parked on a level plane. Figure 2 shows maximum allowable degrees that the unit can be mounted above or below level. If the roof of the vehicle is sloped (not level) such that the roof top air conditioner cannot be mounted within the maximum allowable degree specifications, an exterior leveling shim will need to be added to make the unit level. A typical leveling shim is shown in Figure 3. Once the roof top air conditioner has been leveled, some additional shimming may be required above the interior ceiling assembly. The roof top air conditioner and the interior ceiling assembly must be square with each other before they are secured together. After the mounting hole area is properly prepared, remove the carton and shipping pads from around the roof top air conditioner. Carefully lift the unit on top of the vehicle. Do not use the outer plastic shroud for lifting. Place the roof top air conditioner over the prepared mounting hole. The front section of outdoor unit of air conditioner must be in the same direction as the vehicle, which is useful for reducing wind resistance.

Step 3: Mounting Outdoor Unit

1. Open the package and take out the outdoor unit.

• When taking out the outdoor unit after unpacking, do not lift the air outlet grille at the back of outer case (see Figure 4-1).

2. Fix the outdoor unit at the roof of vehicle and then drill holes.

• Place the outdoor unit at the roof of vehicle;lift the outdoor unit and then place the outdoor unit after drilling holes at the roof of vehicle. Do not drag the outdoor unit. Otherwise, the seal may fall off(see Figure 4-2).

Step 4: Installing the Ceiling Assembly

Make sure that you have properly matched the roof top air conditioner and interior ceiling assembly. Caution before tightening bolts:

1. The applicable thickness of vehicle roof ranges from 1.2”~3.1”.
2. Before tightening bolts, screw in the four bolts manually and prohibit screwing forcibly.
3. When screwing bolts, you can use automatic tool. Do not tighten one bolt completely and then tighten other bolts, in order to prevent sticking of screw thread.
4. The max torque for tightening ranges from 2.3Nm~2.5Nm.

The following step by step instructions must be performed in the following sequence to ensure proper installation:

1. Carefully take the ceiling assembly out of the carton(The remote control packed with the ceiling assembly).
2. Remove the ceiling grille from the ceiling assembly.
3. Before the ceiling assembly can be mounted to the roof top air conditioner, the fabric duct collar must be fastened to the basepan of the roof top air conditioner with 4 screws by upper duct plate (see Figure 5- 2、Figure 6-1、Figure 5、Figure 5-1).
4. Before lifting the ceiling assembly, pull the fabric duct collar so it hangs out of the way and does not get caught under the ceiling assembly frame.
5. Secure the ceiling assembly frame to the roof top air conditioner with the mounting bolts (see Figure 5).You must start (thread) the mounting bolts by hand to avoid crossthreading. DO NOT START THE MOUNTING BOLTS WITH AN AIR GUN.The mounting bolts should be tightened, process is completed when the basepan gasket has been evenly compressed.
6. Set the fabric air duct into the duct opening of installation plate sub-assy and cut off four corner of fabric air duct. Because the thickness of vehicle top is different, the distance between the opening and the installation plate sub-assy is shown in figure 6.
7. Fasten each side of the fabric duct with fitting the bottom duct plate to the ceiling assembly frame with 4 screws (see Figure 6).Trim any excess fabric that may extend beyond edge of bottom duct plate.

Step 5: Electrical Wiring

Warning

Make sure that all power supply to the unit is disconnected before performing any work on the unit to avoid the possibility of shock or injury and/or damage to the equipment. When the interior ceiling assembly frame is properly secured to the roof top air conditioner, the following electrical connections must be performed.

Routing 115V AC Wiring

1. As shown in Figure 7, the outdoor unit has two sets of outgoing wires, which are power cord (high current) and the control signal wires respectively. The former one should be directly connected to terminal box while the latter one should be connected to the control signal wire of the indoor unit.
2. Route a copper ,with ground, supply wiring with minimum #14AWG , the wiring from its power source to the junction box. Do not attach them at this time.
3. Take the roof top air conditioner power cord to connect to the side of the junction box.
4. Remove the junction box cover (2 screws).Take the power cord and make it get into the box through the strain relief that is provided (see Figure 8).
5. Connect the power cord to the black, white and ground wires found in the junction box with a terminal board. CAUTION Connect black wire to black wire, white wire to white wireand the groundwiretoearth.(seeFigure9) Note:Figure 9,When connecting the power cord,please use the pipe for preventing cutting power wire.
6. Tighten the strain relief clamp to secure the supply power cord. DO NOT OVERTIGHTEN. Reinstall the junction box cover.
7. Connect connector and secure the clamp.

Step 6: Completing the Installation

To complete the installation and system checkout requirements, the following steps must be performed.

1. Check the thermostat position. Make sure the thermostat is routed through the holding guide and is not touching any metal surface.
2. Make sure the guide louver and the filters are properly positioned in the ceiling grille.
3. Secure the ceiling grille to the ceiling assembly frame with 4 screws. (see Figure 11).
