3) Selection of copper and heat insulation materials

• When utilizing business copper pipes and fittings, observe the next: 1) Insulation materials: Polyethylene foam Heat switch fee: 0.041 to 0.052W/mK (0.024 to 0.030Btu/fth°F (0.035 to 0.045kcal/mh°C)) Be positive to make use of insulation that’s designed to be used with HVAC Systems.

Step7. install the mounting plate

• The mounting plate should be put in on a wall that can support the weight of the indoor unit.

1) Temporarily secure the mounting plate to the wall, be sure that the plate is the degree, and mark the boring factors on the wall.

2) Secure the mounting plate to the wall with screws.

Step8. Boring a wall gap and putting in wall embedded pipe

• For partitions containing steel frames or steel board, you should use a wall embedded pipe and wall cowl within the feed-through gap to forestall potential warmth, electrical shock, or fireplace.

• Be positive to caulk the gaps across the pipes with caulking materials to forestall water leakage.

 1) Bore a feed-through gap of 3-1/Eight inch (80mm) within the wall so it has a downward slope towards the surface.

2) Insert a wall pipe into the opening.

3) Insert a wall cowl into the wall pipe.

 4) After finishing refrigerant piping, wiring, and drain piping, caulk pipe gap hole with putty.

Step9. Laying piping, hoses, and wiring

1. Right-side, right-back, or right-bottom piping

1) Attach the drain hose to the underside of the refrigerant pipes with adhesive vinyl tape.

 2) Wrap the refrigerant pipes and drain hose along with insulation tape.

3) Pass the drain hose and refrigerant pipes using the wall gap, then set the indoor unit on the mounting plate hooks through the use of (triangle icon) the markings on the high of the indoor unit as information.

2. Left-side, left-back, or left-bottom piping

1) Replace the drain plug and drain hose.

 2) Attach the drain hose to the underside of the refrigerant pipes with adhesive vinyl tape.

3) Be positive to attach the drain hose to the drain port instead of a drain plug

4) Shape the refrigerant pipes alongside the pipe path marking on the mounting plate.

5) Pass drain hose and refrigerant pipes using the wall gap, then set the indoor unit on mounting plate hooks, utilizing the(triangle icon) markings on the high of the indoor unit as information.

 6) Pull within the inter-unit wire.

 7) Connect the inter-unit pipes.

8) Wrap the refrigerant pipes and drain hose along with insulation tape as the suitable determine, in case of setting the drain hose using the again of the indoor unit.

 9) While exercising care so that the inter-unit wire doesn’t catch the indoor unit, press the underside fringe of the indoor unit with each hand till it’s firmly caught by the mounting plate hooks. Secure indoor unit to the mounting plate with indoor unit fixing screws 3/16 × half-inch (M4 × 12mm)

3. Wall embedded piping

• Insert the drain hose to this depth so it gained be pulled out of the drain pipe.

Step10.  Wiring

1) As proven within the illustration on the right-hand aspect, insert the wires together with the bottom wire into the conduit and save them with a lock nut onto the conduit mounting plate.

2) Insert the wires together with the bottom wire into the tube.

3) Strip wire ends (9/16 inch (15mm)).

4) Match wire colors with terminal numbers on indoor and outside unit’s terminal blocks and firmly screw wires to the corresponding terminals.

 5) Connect the bottom wires to the corresponding terminals.

 6) Pull the wires and test that the wires are securely fastened to the terminal block.

 7) In case of connecting to an adapter system, run the distant controller cable and connect the S21. (Refer to P5 when connecting to an HA system.)

 8) Shape the wires so that the service lid matches securely, then shut the service lid.

Step11. Drain piping

1) Connect the drain hose, as described properly.

2) Remove the air filters and pour some water into the drain pan to test the water flows easily.

3) When the drain hose requires an extension, get hold of an extension hose commercially obtainable. Be certain to thermally insulate the indoor part of the extension hose.

4) When connecting an inflexible polyvinyl chloride pipe (nominal diameter 1/2 inch (13mm)) onto the drain hose connected to the indoor unit as with embedded piping work, use any commercially obtainable drain socket (nominal diameter 1/2 inch (13mm)) as a joint.

Step12. Trial operation

1) Measure the provision voltage and guarantee that it falls within the specified vary.

2) Trial operations ought to be carried out in both cooling and heating mode.

• In cooling mode, choose the bottom programmable temperature; in heating mode, choose the very best programmable temperature.

a) Trial operation could also be disabled in both modes relying on the room temperature. Use the distant controller for trial operation as described below.

b) After the trial operation is full, set the temperature to a standard stage (78°F to 82°F (26°C to 28°C) in cooling mode, 68°F to 75°F (20°C to 24°C) in heating mode).

c) For safety, the system disables restart operation for Three minutes after it’s turned off.

3) Carry out the check operation following the operation guide to make sure that all features and components, equivalent to fin motion, are working correctly.

• The air conditioner requires a small quantity of energy in its standby mode. If the system shouldn’t be for use for a while after setting up, shut off the circuit breaker to remove pointless energy consumption.

• If the circuit breaker journeys to close off the ability to the air conditioner, the system will restore the unique operation mode when the circuit breaker is opened once more.

  Trial operation from the distant controller  
1) Press the “ON/OFF” button to activate the system.  
2) Press the “TEMP” button (2 places) and the “MODE” button at a similar time.  
3) Press the “MODE” button twice. (“ T ” will seem on the show to point that trial operation mode is chosen.)
