Installation Guidance

Installation instructions

• Read this Manual thoroughly before installation and understand the guidance.
• Do not add other parts or restructure the product in the installation.
• Consult with HOUGHTON or the local distributor in the case of unusual applications or installation conditions that are not specifically covered by this manual.

Installation requirements

• The RV or caravan roof shall be able to support the air-conditioner’s weight .
• Minimum thickness of roof is 25mm; maximum thickness of roof is 70mm.
• If the roof’s thickness is greater than 70mm, you can purchase a “Thick roof kit ” to suit your unit from HOUGHTON or the local distributor

Installation position

Before the installation, consider the installation position:

• The air-conditioner outdoor unit shall be installed at the center of the roof to make sure balance of the air flowing.
• The installation position of the outdoor unit shall be consistent with the traveling direction of the caravan. ŸWhen installing ensure that there is sufficient room for the plenum assembly to be installed.
• Consider the installation position and ensure that outlets are at least 400mm away from cupboards walls bulkheads that can redirect conditioned air back to the return air intake. If an outlet is closer than 400mm from an obstruction, then it should be sealed closed. Failure to do this will result in a unit that frequently cycles on and off.
• 360×360mm (400×400mm) cutting position shall avoid roof cladding joints where ever possible.
• There shall be a space of 100mm minimum all around the roof top unit to ensure suitable air flow and access for maintenance

Measures in mm.}

F = Direction of travel

1. Position of the outdoor unit
2. Position of the plenum
3. Square hole

• The figure below shows the minimum clearance distance required between the
  AEOLUS air-conditioner and any obstructions on the roof and the clearance required on the ceiling for the plenum installation.Measure from the reference position of the 360×360mm (400× 400mm) square hole.Remember to add 100mm clearance around roof top uint perimeter.

NOTE

• Angle of inclination of the air conditioner shall not be larger than 5° and the back part of the air-conditioner shall not be higher than the front part.
• For advice on installations outside of these limits please contact with HOUGHTON or the local distributor.

Load bearing of roof

• The roof shall be able to bear the weight of the air-conditioner and shall be level without accumulating water. It is suggested that the caravan manufacturer confirms the suitability of the roof for load bearing
  Schematic diagram after fixing the block
  

• if the installation hole is noe preexisting then consult your caravan manufacturer for the most suitable way to cut the installation hole.
  

• The 360×360mm(400×400mm) hole shall be boarded up with wood sections that are at least 20mm thick. This boarding is to ensure that the roof will not crush from the installation bolts and that air conditioned air does not enter the ceiling space.

Power supply
Electrical power supply cable

• Determine the battery position of the vehicle, reasonably arrange the direction and fixed position of the electrical power supply cable, and fix the electrical power supply cable with a tie to prevent vibration and wear.
• Confirm and mark the positive and negative poles of the battery group, and connect the red cable with “+”Pole, black connected to “-” pole .
• The electrical power supply cable must be ≥NO.8AWG and the communication cable must be ≥ NO.18AWG.

Installation of roof mount

• Make sure the roof is clean and dry and free from oil or grease.
• Confirm orientation by starting with the “this side up” logo upwards.
• Turn the part over and on the reverse side of “This side up”, apply the self-leveling RV Roof sealant uniformly over the path shown.
• Turn the part over again and make sure “This side up” is up. Press down firmly over the installation hole and remove any sealant that has squeezed out to form an effective seal.

Important – do not run sealant inside the mounting bolt holes.This will cause breaks in the seal.Always run the sealant around the outside of the bolt holes as shown.

Installation of outdoor unit

• Remove the outdoor unit from the carton and move it to the installation position on theŸroof.
• Put the outdoor unit over the chassis reinforced support and properly adjust the position to make sure they mate and the four bolt holes on the corners align

Connect the power supply and 485 communication

1. power connection cable
2.  485 communication cable
3. OT terminal block

• It is the installers responsibility to ensure that local wiring regulations are followed when connecting to mains supply.
• Look upward from inside the caravan, there are red power connection cable and black power connection cable. Connect the power connection OT terminal block to the large terminal block.
• Connect the extemal electrical power supply cable to the large terminal block and note the positions of the “+”pole and “-“pole
• Look upward from inside the caravan, there are red 485 communication cable and black 485 communication cable. Connect the 485 communication cables to the small terminal block.
• Connect the extemal 485 communication cables to the small terminal block and note the positions of the “+”pole and “-“pole.

NOTE

• Match the corresponding “+” pole and”-” pole and firmly tighten up the screws to make sure the power cable is not loose or improperly connected, otherwise a short circuit or fire could be caused.

Installation of the plenum mounting bracket

• Connect M8 bolts, washers and fixing metal plates in order shown.
• Lift the plenum mounting bracket toward the air conditioner.
• Insert M8 bolts, washers and metal clamping bars into the 4 corner holes of the plenum mounting bracket. Screw the bolts into their receiving threads by hand to ensure engagement.
• Ensure all bolts have started correctly for at least 2 or 3 rotations to avoid cross threading.
• Ensure the metal clamping bars align with the corresponding recess in the plenum mounting bracket as the bolts are tightened.
• Evenly tighten up all four bolts.

NOTE

• Tighten the bolts to 10-12 Nm torque.
• Do not exceed 12Nm(9 lbf ft).

Connection of air inlet duct

• Grasp the free end of the air inlet duct and pull it down until it touches the plenum mounting bracket.
• Continue to pull the rim of the duct down until it engages with the four latches on the plenum mounting bracket.
• The duct is correctly connected when you hear the four distinct clicking sounds of the latches and the rim of the duct is parallel to the surface of the bracket.
• If required to fix the rim with the plenum mounting bracket using 4 ST4×10 truss head tapping screw

Installation of the plenum assembly

• Remove the air filter from the plenum by pushing both tabs inwards and then downwards
  

• Connect the socket and plug of the display panel and outdoor unit.

• Note that colors of the wires match: yellow to yellow, red to red, etc.
  

• Attach the plenum assembly to the plenum mounting bracket by engaging the two parts. You will hear four clicks to as the parts connect together.
  

• Fix the plenum assembly on the plenum mounting bracket with four ST4×19 pan head screws.
  

• Remove the screw caps from around the perimeter of the plenum. ŸFix the plenum to the ceiling using the 8 countersunk head screws. ŸReplace the screw caps to the plenum
  

Installation of the air filter

NOTE

• This section is not compulsory – if required to pull the plenum up to the ceiling and remove any gaps

Holder remote control
