Installation for indoor unit

Dimension drawing of indoor unit installation

Mounting plate

1. The wall for installation of the indoor unit shall be hard and firm, so as to prevent vibration.
2. Use the “+” type screw to fasten the peg board, horizontally mount the peg board on the wall, and ensure the lateral horizontal and longitudinal vertical.
3. Pull the peg board by hand after the installation, to confirm whether it is solid.

Wall-through Hole

1. Make a hole with an electric hammer or a water drill at the predetermined position on the wall for piping, which shall slant outwardly by 5°-10°.
2. To protect the piping and the cables from being damaged running through the wall, and from the rodents that may inhabit in the hollow wall, a pipe protecting ring shall be installed and sealed with putty.

Note : Usually, the wall hole is Ф 2.4″~Ф3.2″. Avoid pre-buried power wire and hard wall when making the hole.

Route of Pipeline

1. Depending on the position of the unit, the piping may be routed sideway from the left or the right (Fig 1), or vertically from the back( Fig 2 )(depending on the pipe length of the indoor unit). In the case of sideway routing, cut off the outlet cutting stock of the opposite side.

Install the connection pipe

1. Remove the mountings and pull the indoor unit pipe out of the housing.
2. Connect the connecting pipe to the indoor unit: Aim at the pipe center, tighten the Taper nut with fingers, and then tighten the Taper nut with a torque wrench, and the direction is shown in diagram on the right. The torque used is shown in the following table.

IMPORTANT: For units with quick connectors, please refer to the booklet of “Install the connection pipe(the unit with the quick connectors)”.

Wrap the Piping

1. Use the insulation sleeve to wrap the joint part of the indoor. unit and the connection pipe, and then use insulating material to pack and seal insulation pipe, to prevent generation of condensate water on the joint part.
2. Connect the water outlet with drain pipes, and make the connection pipe, cables, and the drain hose straight.
3. Use plastic cable ties to wrap the connecting pipes, cables and drain hose. Run the pipe sloping downward.

Fixing the Indoor Unit

1. Hang the indoor unit on the peg board, and move the unit from left to right to ensure that the hook is properly positioned in the peg board.
2. Push toward the lower left side and the upper right side of the unit toward the peg board, until the hook is embedded in the slot and makes a “click” sound.

Interconnection cord installation

Connect interconnection cord of indoor unit

1. Open the panel, remove the screw on the wiring cover and then take down the cover.

2. Make the interconnection cord go through the cable-cross hole at the back of indoor unit and then pull it out from the front side. (Some models do not have a signal cable.)

3. Remove the wire clip; connect the interconnection cord to the wiring terminal according to the wiring diagram; tighten the screw and then fix the interconnection cord with wire clip.
   NOTE:

   • Conditioner. We cannot delete the possibity that some special type of wiring diagrams are not included.
   • The diagram are for reference only. If the entity is different from this wiring diagram, please refer to the detailed wiring diagram adhered on the unit which you purchased.

4. Put wiring cover back and then tighten the screw

5. Close the panel.

After installation check

1. The screws whether have been fixed effectively and there is no risk of loosening.
2. Connector of display board whether put in the right place and do not touch the terminal board.
3. Control box cover whether cover tightly.

Dimension drawing of outdoor unit installation

Install the connection pipe
Connect the Outdoor Unit with Connecting Pipe: Aim the counter-bore of the connecting pipe at the stop valve, and tighten the Taper nut with fingers. Then tighten the Taper nut with a torque wrench.

When the length of the connecting pipe is changed, extra amount of refrigerant need to be added or reduced, so that the operation and performance of the air conditioner will not be compromised.

Note: This table is for reference only.
IMPORTANT: For units with quick connectors, please refer to the booklet of “Install the connection pipe(the unit with the quick connectors)”.

Wiring Connection

1. Loosen the screws and remove E-parts cover from the unit.
2. Connect the cables respectively to the corresponding terminals of the terminal board of the outdoor unit (see the wiring diagram), and if there are signals connected to the plug, just conduct butt joint
3. Ground wire: Remove the grounding screw out of the electric bracket, cover the grounding wire end onto the grounding screw and screw it into the grounding hole.
4. Fix the cable reliably with fasteners (Pressing board).
5. Put the E-parts cover back in its original place and fasten it with screws.

Wiring diagram

NOTE:

• This manual usually includes the wiring mode for the different kind of air conditioner. We cannot exclude the possibility that some special type of wiring diagrams are not included .
• The diagram are for reference only. If the entity is different from this wiring diagram, please refer to the detailed wiring diagram adhered on the unit which you purchased.

Expelling the air

Outdoor unit refrigerant discharging method
After the pipe side connection is complete, proceed as follows.

• Vacuum Pumping Method (R410A refrigerant evacuation must use the vacuum pumping method) Before working on the air conditioner, remove the cover of the stop valve(gas and liquid valves)and be sure to re-tighten themafterwards. (to prevent the potential air leakage)

1. To prevent air leakage and spilling tighten all connecting nut of all flare tubes.
2. Connect the stop valve, charge hose, manifold valve, and vacuum pump.
3. Fully open the handle Lo of the manifold valve and apply vacuum for at least 15 minutes and check that the compound vacuum gauge reads -0.1MPa(-76cmHg).
4. After applying vacuum, fully open the stop valve with a hex wrench.
5. Check that both indoor and outdoor connections are free of air leakage.

IMPORTANT: The unit with the quick connectors does not require vacuum pumping.

Outdoor condensation drainage(Heat pump type only)

When the unit is heating, the condensing water and defrosting water can be out reliably through the drain hose.

Installation: Install the outdoor drain elbow in @ 25 hole on the base plate, and joint the drain hose to the elbow, so that the waste water formed in the outdoor unit can be drained out to a proper plate.

Check after installation and test operation

Check after installation

Electrical Safety Check

1. If the supply voltage is as required.
2. If there is any faulty or miss connection in each of the power, signal and grounding wires.
3. If the grounding wire of the air conditioner is securely grounded.

Installation Safety Check

1. If the installation is secure.
2. If the water drain is smooth.
3. If the wiring and piping are correctly installed.
4. Check that no foreign matter or tools are left inside the unit.

Leak test of the refrigerant
Depending on the installation method, the following methods may be used to check for suspect leak, on areas such as the four connections of the outdoor unit and the cores of the cut-off valves and t-valves:

1. Bubble method: Apply of spray a uniform layer of soap water over the suspected leak spot and observe carefully for bubble.
2. Instrument method: Checking for leak by pointing the probe of the leak detector according to the instruction to the suspect points of leak.

Test Operation

Test Operation Preparation:

• Verify that all piping and connection cables are well connected.
• Confirm that the values at the gas side and the liquid-side are fully open.
• Connect the power cable to an independent power socket.
• Install batteries in remote control.

Test Operation Method:

1. Turn on the power and push the ON/OFF switch button of the remote controller to start the air conditioner.
2. Select COOL, HEAT (not available on cool-only models), SWING and other operation modes with the remote controller and see if the operation is ok.

Specific caution
