CONNECT THE DRAIN PIPE

1. Install indoor unit drain pipe

The outlet has PTI screw thread, Please use sealing materials and pipe sheath (ﬁ tting) when connecting PVC pipes.

Cautions

• The drain pipe of indoor unit must be heat insulated, or it will condense dew, as well as the connections of the indoor unit.

• Hard PVC binder must be used for pipe connection, and make sure there is no leakage.

• With the connection part to the indoor unit, please be noted not to impose pressure on the side of indoor unit pipes.

• When the declivity of the drain pipe downwards is over 1/100, there should not be any winding.

• The total length of the drain pipe when pulled out traversely shall not exceed 20m, when the pipe is over long, a prop stand must be installed to prevent winding.

• Refer to the ﬁ gures on the right for the installation of the pipes.

Put as deep as possible (about 10cm)

NORMAL FUNCTION OF THE AIR CONDITIONER

The following symptoms do not indicate air conditioner malfunction.

1. The system does not operate

• The system does not restart immediately after the ON/OFF button is pressed. If the OPERATION lamp lights, the system is in normal condition. The safety device operates to prevent overload of the system. After 3 minutes, the system will turn on again automatically.

• The system does not restart immediately when TEMPERATURE SETTING changed. If the OPERATION lamp lights, the system is in normal condition. If the timer light is ﬂ ashing operation is being delayed by the safety device. It does not restart immediately because the compressor has been stopped and requested to start within the delay period. A safety device operates to prevent overload of the system. After 3 minutes, the system will turn on again automatically.

• The system does not start immediately after the power supply is turned on. Wait one minute until the microcomputer is prepared for operation.

1.1 White mist comes out of a unit

• When humidity is high during cooling operation. (In dusty locations or after construction work) If the inside of an indoor unit is contaminated, the temperature distribution inside a room may become uneven. It is necessary to clean the inside of the indoor unit. The unit should be cleaned by a qualiﬁ ed service person familiar with the unit.

• When the system is changed over to HEATING OPERATION or after DEFROST OPERATION. Moisture generated on the coil by the DEFROST becomes vapour and exists.

1.2 Noise of air conditioners

• A continuous ﬂ ow “Shuh” sound is heard when the systems is in COOLING or DEFROST OPERATION. This is the sound of refrigerant gas ﬂ owing through both indoor and outdoor units.

• A “Shuh” sound which is heard at the start or immediately after operation. It may also be heard at the start or immediately after a DEFROST OPERATION. This is the noise of refrigerant caused by the start and stop of the ﬂ ow.

• A “Pishi-pishi” squeaking sound is heard when the system is in operation or just after operation. Expansion and contraction of plastic parts caused by temperature change makes this noise.

1.3 Dust from the units

• Dust may blow out from the unit when starting after long off cycles. Dust absorbed by the unit blows out.

• The units give off odours. The unit absorbs the smell of rooms, furniture, cigarettes, etc., and then emits them.

EMERGENCY OPERATION

• Units are equipped with a switch to run emergency operation mode. Pushing the emergency switch turns the unit on; pushing it again turns if off (toggle action). During emergency operation, the remote controller cannot be used and the power LED light will ﬂ ash at intervals, while the other LED lights will indicate the operation of the Diagnostic Codes. In Emergency Operation and cooling units the temperature will be set at 24°C and the fan on Auto. Heating units will switch to auto mode at a temperature set point of 24°C and the fan will run on auto mode.

• After a power failure the unit restarts automatically in the same mode as before the failure, when power is resumed.

EMERGENCY OPERATION

PROTECTION FUNCTION

Auto Restart Function

• The unit will automatically restart after loss of the electrical power supply. When power is restored; the unit operation will restart according to all parameters set before the loss of power.

ANTI-ICE and ANTI-OVERHEAT

• This feature is used to prevent the indoor unit from freezing during cool or dry operation and overheating in heat mode. During execution of anti-ice operation and anti-overheating, the compressor will stop operating and the fan will continue to run until the coil temperature reaches predetermined set points, at which time the unit will resume normal operation.

Low Voltage

• The feature is used to protect against any damage to the unit caused by ﬂ uctuation of voltage. If voltage is lower than the lower limit for approximately 10 seconds or longer, compressor operation will be temporarily stopped. Normal operation will resume when the voltage returns above the set limit for a minimum of 10 seconds. If the time elapsed is less than 3 minutes then the compressor start up will be delayed until 3 minutes has passed.

Filter Care and Filter Alarm

• Replace Air Purifying ﬁ lter if ﬁ tted.

• The ﬁ lters should be cleaned regularly, i.e, once a month, or more frequently depending on conditions. The control is equipped with a ﬁ lter alarm; After a certain numbers of hours of operation, ﬂ ashing lights will indicate that it is time to clean the ﬁ lter. The alarm is reset by pressing the ﬁ lter button or the transmitter.

MAINTENANCE

The units are designed to operate for long periods of time with a minimum of maintenance. However, the following operation must be performed regularly.

Air ﬁ lter Clean Every month or more often if necessary

Unit casing Clean Every month or more often if necessary

Drain pan and evacuation piping Clean and check for obstructions Each season before start up*

Indoor/outdoor coils Clean Each season before start up*

Compressor No need

* This operation must be carried out by qualiﬁ ed personnel only.

S Turn off the main breaker or disconnect the main power supply.

Notes

• Don’t spill water : There is a danger of electric shock.
