SeaLion Airconditioners

General Instructions

Please read these instructions carefully before installing the airconditioner.

It is preferable that an appropriately qualified tradesperson or technician carries out the installation, or the warrantee may be voided.

Please follow the numbered sequence for correct installation.

Selection of Installation Locations

Indoor Unit

Do not install near doorways or areas affected by steam or heat from other items.

Ensure that there are no obstacles in the installation area, such as pre-existing pipes or electrical wires in the wall mounting area.

Ensure that there will be no obstructions or interference with the airflow.

Ensure that mounting clearances are observed (see diagram) between walls, ceilings or other obstacles (e.g., light fittings or cupboards).

Best performance is achieved by mounting the unit 2 meters above floor level.

Outdoor Unit

Ensure the mounting location is free of plants that may grow into or across the unit. Do not grow plants or place pet kennels near the unit, as variable airflow may adversely affect plants or animals.

Ensure that mounting clearances are observed (see diagram) between walls, roofs or other obstacles.

Keep the unit away from other heating/cooling outlets and any inflammable gases or fuel storage areas.

Ensure the installation base and any supporting frame is strong and well secured, and that the unit is mounted on a level surface.

If you cover the outdoor unit with a canopy or shelter, ensure that airflow is not restricted.

Outdoor Unit

Make sure the outdoor unit is firmly fixed to its base so it cannot be dislodged. A concrete base is recommended, with the unit positioned as indicated in the diagram.

If the unit is to be installed in a high wind location, the outdoor unit should be installed near a wall to allow normal fan operation, with a blocking plate.

If possible, place hard rubber matting sections between the unit base and the mounting location to reduce vibration.

Indoor Unit

Ensure the wall has suitably solid backing to safely hold the unit (refer to the weight chart for the unit selected).

Do not attempt to mount on plaster or similar walls. All screws must hold into concrete, steel or solid wood, or equivalent suitable substances.

Fasten the mounting block to the wall with 4 "+" head screws of suitable length and width.

The hole for pipe, electrical and drainage connections through the wall should be 70mm in diameter, and should slant slightly downwards from the inner to the outer wall.

Ensure the unit is level both horizontally and vertically. Failure to do so may prevent the drain from working, resulting in water dripping when the unit is operated in cooling mode.

When attaching the unit to the mounting block, ensure it is centred.

To lock in place, push the indoor unit back and down on both ends evenly against the mounting block until the hangers enter their grooves and a gentle "click" is heard.

Checking the Waste Water Discharge

  1. Remove the indoor unit front frame:
    1. Turn the airflow handle from vertical to horizontal
    2. Take off the two covers from the front frame and then unfasten the two fixture screws
    3. Pull the frame towards you and remove

    To return the front frame, turn the airflow handle back to vertical, replace the frame, screws and covers. Check that the front frame is firmly inside the fixture groove on top of the unit.

  2. Check the water discharge:
    1. Pour a cup of water into the drain discharge groove
    2. Check that the water flows through the drain discharge hole and then out through the drain

Shaping and Fitting Pipework

Use the supplied insulation material to thoroughly wrap all pipes, electrical wires and the water discharge (drain) line from top to bottom. (See diagrams.)

Cover all connection points and secure the insulation with the supplied plastic rings.

Make sure you use strong clips to secure the pipework and drain to the external wall. (These clips are not supplied.) Ensure that any extension to the drain is also securely fastened.

Pipe Connections

To connect the pipe to the unit:

  1. Place a small amount of oil from the supplied bottle over the flared pipe end, flare inside and unit connection thread. This will lubricate the pipe and thread and help ensure that easy threading takes place
  2. Carefully connect the pipe with the appropriate unit connection, ensuring it is properly centred to avoid cross threading
  3. Finish tightening by using an adjustable wrench or torque wrench (if using the latter, follow the torque settings in the table below)
Unit sizeConnection pipe typePipe diameter
23, 25, 33, 35Low pressure
9.52mm 3/8"

Air pipe (diameter) 12.7mm (1/2")55N. m
Air pipe (diameter) 15.88mm (5/8")75N. m

Do NOT over-tighten the pipe-work connections and do NOT use thread tape.

Purging Pipes

You MUST next purge the pipes of the dry gas to enable correct airconditioner operation. Purging (when cared out correctly) should remove ONLY the dry non refrigerant gas from the vapour and liquid pipelines and head (inside) unit. Severe damage will occur and any warrantee will be voided if these steps are not correctly followed.

The outdoor unit has two small brass post-valves on its right-hand end where the indoor unit pipe-work has been attached.

  1. Remove the post-valve covers from both
  2. The post-valve which has the large suction (or vapour) pipe attached has an additional single small valve and cover (1/4 inch flare cover); this cover should also be removed revealing the schrader valve (similar to a bicycle or car tyre valve)
  3. Insert an allen key (hexagonal wrench) into the post-valve with the smaller pipe, and turn it open to 90 degrees for eight seconds
  4. Close the valve
  5. Check whether there is any gas leakage from the system, and adjust and tighten as necessary. You can check for gas leakage by dripping a strong soap (e.g., liquid detergent) and water mixture over the parts involved. If there is a leak, bubbles are formed
  6. Gently push in the top of the schrader valve using a blunt soft object such as a wooden meat skewer or cotton bud, until all the gas has been released
  7. Repeat steps 3 to 6 again so that the unit has been purged twice
  8. Open the two post-valves fully using an allen key, then back them off quarter of a turn from fully open
  9. Replace all covers (including the auxilary - schrader valve - cover)
  10. It is preferable not to install pipe-work on wet, rainy or foggy days

Electrical Connections

  1. Unscrew the control panel cover screw and take off the control panel cover
  2. Connect the wires according to the colour
  3. Connect the signal (thin wire) connection plug
  4. Make sure the yellow and green wires are connected to the earth
  5. Fasten the cable connection fastener over the wire to the terminal board control panel
  6. Screw the control panel cover back into place

Test Operation

  1. Make sure all the pipes and wires are connected
  2. Make sure the liquid and suction line valves are correctly set
  3. Plug in the unit to mains power using the three pin plug
  4. Run the unit in cooling mode using the remote control to turn it on for 30 minutes or longer
  5. Make sure the air coming out of the unit is at least 8 degrees colder than the air going into the indoor unit
