Mestic-RTA-2500-Rooftop-Air-Conditioner-FIG-25

Before installation, please check whether the unit is assembled with three pieces of rubber pads and square sealing strip.

WARNING
Moving parts may cause personal injury. Be careful when test the unit. Do not operate the unit with exterior cover removed.

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 opening must be cut (if there is no hole) or you may use existing vent holes.

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 356x356mm, the opening must be enlarged. If the opening exceeds 356x356mm, a mounting plate (frame) must be fabricated to reduce the opening size (See Figure 1).

CASE B.
If a roof ventilation opening is not used, a new opening must be cut into the roof of the vehicle. A matching opening will also have to be cut into the ceiling inside the vehicle. Be careful as the roof piece can get stuck if the roof is multi-layered. When the opening in the roof and the ceiling are the correct size, a support structure must be fitted between the outside roof and the ceiling inside. The reinforced framework must comply with the following guidelines:

Mestic-RTA-2500-Rooftop-Air-Conditioner-FIG-26

  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.
  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

  1. 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.
  2. 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.
  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.
  4. 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.
  5. The point end (nose) of the shroud must face toward the front of the vehicle.

Note : Try your best to put the unit on the horizontal surface for operation. The unit can only operate for a short time at the maximum sloping angle of 5º for preventing water leakage.

MOUNTING OUTDOOR UNIT

  1. Open the package and take out the outdoor unit 1) When taking out the outdoor unit after unpacking, do not lift the air outlet grille at the back of outer case (see Figure4-1).
  2. Fix the outdoor unit at the roof of vehicle and then drill holes. 1) 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 sealing strip may fall off (see Figure4-2).

INSTALLING THE CEILING ASSEMBLY

NOTICE
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 30mm~80mm.
  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 installing the outdoor unit of recre- ational vehicle air conditioner on the vehicle’s top, preinstall the plate of air vent and foam (upper) on the chassis of the outdoor unit with 4pc of screws (25mm long) (See fig.5-1) .
  4. Then carry the outdoor unit to the vehicle’s top and align with the openings on the vehicle’s top. Use 2 sets of mounting plate assembly and 4 screw bolts to mount the outdoor unit (See fig. 5). the basepan gasket has been evenly compressed.
  5. Before installing the air duct assembly of the indoor unit of recreational vehicle air conditioner, assemble the foam assembly according to the thickness of the vehicle’s top. After simulated installation, use an appropriate amount of sponge and foam assembly. Stick the sponge and foam assembly with double faced adhesive tape (prepared by user) (See fig.5-2, 5-3)..
  6. Install the foam assembly on the air duct assembly. Use 4 screw bolts to fix the air duct assembly onto the mounting plate. After connecting the outdoor unit with indoor unit, check whether the foam assembly has come loose (See fig.5).

You must start (thread) themounting bolts by hand to avoid cross-threading. DO NOT START THE MOUNTING BOLTS WITH AN AIR GUN. The mounting bolts should be tightened, process is completed when

ROUTING 220-240V AC 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. After the interior ceiling assembly frame is properly secured to the roof top air conditioner, the following electrical connections must be performed.

  1. As shown in fig.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 the power supply terminal while the latter one should be connected to the control signal wire of the indoor unit.
  2. As shown in fig.8, the indoor unit has one set of control signal wires, with 4 wiring terminals in total.
  3. As shown in the picture, connect the wiring terminals of indoor and outdoor units one by one. Then use a piece of sponge to wrap the wiring terminals together, with each terminal separately encircled by the sponge. Avoid gaps between each wire.Mestic-RTA-2500-Rooftop-Air-Conditioner-FIG-33
  4. shown in the picture, use a piece of thermal insulating jacket to enclose the wiring terminals and sponge. Then glue the thermal insulating jacket and fasten it with cable ties.

NOTE

  1. Cable ties must be attached to the area with both sponge and thermal insulating jacket;
  2. Before installing the front panel of indoor unit, put the thermal insulating jacket on top of the air duct.
