Drainpipe Installation

The drainpipe is used to drain water away from the unit. Improper installation may cause unit and property damage.

WARNING

• Insulate all piping to prevent condensation, which could lead to water damage.
- If the drainpipe is bent or installed incorrectly, water may leak and cause a water-level switch malfunction.
- In HEAT mode, the outdoor unit will discharge water. Ensure that the drain hose is placed in an appropriate area to avoid water damage and slippage.
- DO NOT pull the drainpipe forcefully. This could disconnect it.

NOTE ON PURCHASING PIPES

Installation requires a PVC tube (exterior diameter = 1in(25mm)) (depending on models), which can be obtained at your localhardware store or dealer.

Indoor Drainpipe Installation

Install the drainpipe as illustrated in the following figure.

Connect drainpipe to the indoor unit via drain adaptor.

Drainpipe Metal clamp connecting port Drainpipe

1-1.5m (39-59') Downward slope 1/100

NOTE ON DRAINPIPE INSTALLATION

• When using an extended drainpipe, tighten the indoor connection with an additional protection tube to prevent it from pulling loose.
• The drainpipe should slope downward at a gradient of at least 1/100 to prevent water from flowing back into the air conditioner.
• To prevent the pipe from sagging, space hanging wires every 1-1.5m (39-59").
• If the outlet of the drainpipe is higher than the body's pump joint, provide a lift pipe for the exhaust outlet of the indoor unit. The lift pipe must be installed no higher than 75cm (29.5") from the ceiling board and the distance between the unit and the lift pipe must be less than 30cm (11.8") (depending on models). Incorrect installation could cause water to flow back into the unit and flood.
• To prevent air bubbles, keep the drain hose level or slightly tiled up (<75mm / 3") (some models).

1 - 1.5m (39-59") ≤30cm (11.8") ≤53cm(20.8") 22cm(8.6") ≤75cm (29.5") 0 - 75mm (3"

0-53cm (20.8") ≥10cm (4")

Pass the drain hose through the wall hole. Make sure the water drains to a safe location where it will not cause water damage or a slipping hazard.

NOTICE

The drainpipe outlet should be at least 5cm (1.9") above the ground. If it touches the ground, the unit may become blocked and malfunction. If you discharge the water directly into a sewer, make sure that the drain has a U or S pipe to catch odors that might otherwise come back into the house.

Drill wall hole

1. Using a 65mm(2.5in) or 90mm(3.54in) (depending on models) core drill, drill a hole in the wall. Make sure that the hole is drilled at a slight downward angle, so that the outdoor end of the hole is lower than the indoor end by about 5mm to 7mm (0.2-0.275in). This will ensure proper water drainage.

2. Place the protective wall cuff in the hole. This protects the edges of the hole and will help seal it when you finish the installation process.

CAUTION

When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive components.

Wall Indoor Outdoor mm7-5 h1572.0-2.0(

NOTE: When the gas side connective pipe is 16mm(5/8in) or more, the wall hole should be 90mm(3.54in).

Refrigerant Piping Connection

When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit's capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.

NOTE ON PIPE LENGTH

Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between the indoor and outdoor units meets the requirements shown in the following table:

1. Using hexagonal wrench fully open both the high pressure and low pressure valves.
2. Tighten valve caps on all three valves (servive port, high pressure, low pressure) by hand. You may tighten it further using a torque wrench if needed.

! OPEN VALVE STEMS GENTLY

When opening valve stems, turn the hexagonal wrench until it hits against the stopper.

Do not try to force the valve to open further.

NOTE ON ADDING REFRIGERANT

Some systems require additional charging depending on pipe lengths. The standard pipe length varies according to local regulations. For example, in North America, the standard pipe length is 7.5m (25'). The refrigerant should be charged from the service port on the outdoor unit's low pressure valve. The additional refrigerant to be charged can be calculated using the following formula:

Liquid Side Diameter

Refrigerant	6.35(1/4")	9.52(3/8")	12.7(1/2")
R401A:(orifice tube in the indoor unit):	(Total pipe length-standard pipe length) x30g(0.32oz)/m(ft)	(Total pipe length-standard pipe length) x65g(0.69oz)/m(ft)	(Total pipe length-standard pipe length) x115g(1.23oz)/m(ft)
R401A:(orifice tube in the outdoor unit):	(Total pipe length-standard pipe length) x15g(0.16oz)/m(ft)	(Total pipe length-standard pipe length) x30g(0.32oz)/m(ft)	(Total pipe length-standard pipe length) x65g(0.69oz)/m(ft)

CAUTION: DOT NOT MIX REFRIGERANT TYPES

DURING TEST RUN

Check for Electrical Leakage During the Test Run, use an electroprobe and multimeter to perform a comprehensive electrical leakage test.

IF ELECTRICAL LEAKAGE IS DETECTED

If electrical leakage is detected, turn off the unit immediately and call a licensed electrician to find and resolve the cause of the leakage.

NOTE: This may not be required for some locations in North America.

Gas Leak Checks

There are two different methods to check for gaseous leaks. Use Fig. 8.1 below as a guide for the critical points to check for leaks.

Soap and Water Method Using a soft brush or spray bottle, apply a soapy water solution to all of the pipe connection points of the indoor and outdoor units, watching to see if any bubbles form. The presence of bubbles indicates there is a leak.

Leak Detector Method If using a leak detector, refer to the device's operation/instruction manual for proper usage instructions.

AFTER PERFORMING GAS LEAK CHECKS

After confirming that all of the refrigerant pipe connections points DO NOT leak, replace the valve cover on the outside unit and wrap and insulate the piping connections of the indoor unit.

Water Discharge Test

• Before the test, make sure that the water discharge pipeline is smooth, and check that each connection is sealed properly.

• Conduct the water discharge test in the new room before the ceiling is paved.

• Connect the power supply, and set the air conditioner to operate in the cool mode. Check the running sound of the drainage pump.

• Keep cool mode running at least 10 min.

• Stop the air conditioner. Wait for three minutes, and then check if there is anything unusual. If the water discharge iping layout is not correct, the excessive water flow will cause the water level error and "EE" error code will be displayed on the display panel. There may even be water overflowing from the water pan.

• Continue to add water until the alarm for excessive water levels is triggered. Check if the drainage pump drains water immediately. After three minutes, if the water level does not fall below the warning level, the unit will shut down. At this time, you need to turn off the power supply, and drain away the accumulated water before you can turn on the unit normally.

• Turn off the power supply, remove the water manually using the drainage plug, and put the test cap back to the original place.

CAUTION

The drainage plug at the bottom of the unit body is used to discharge accumulated water from the drain pan when the air conditioner malfunctions. When the air conditioner is operating normally, make sure the drainage plug is properly plugged to prevent water from leaking.

CAUTION

The power supply must comply with the rating label.
