3. Drill 6.4 mm diameter, 32.0 mm depth on the wall.

6. Drill a piping hole 70.0 mm diameter hole either from the right or to the left fan coil side and make sure that the hole is slightly slant downward.

7. If the wall is hollow please provide a sleeve for tube assembly to protect the drain line, pipings and ﬁ eld connection.

4. Insert the wall plugs.

5. Secure the mounting plate and check for stiffness.

PIPING AND DRAINAGE OF FAN COIL UNIT

1. Route the fan coil tubing with drain hose to the hole. There are four possible tubing routes. For the route 1, 2 and 4 cut the plate to pass the pipe through it, remove sharp edge left on the base pan.

2. Insert the fan coil unit pipings and drain pipe through the hole.

3. Tape the tubing, drain hose, and connecting cable.

4. For the horizontal piping, make sure they are laid along the groove at the back of unit and secure the piping using piping clamp (2 pieces) before ﬁ xing to mounting plate.

5. Secure the unit to the mounting plate.

START-UP NOTICE

1. Be sure that there is no obstruction in the air outlet and intake vents.

2. Check if the ﬁ lter is installed.

3. Check if the the power supply is connected.

4. Check if the ground wire is properly connected.

ADJUSTING AIR FLOW DIRECTION

The horizontal louver and air deﬂ ectors on the air delivery can arranged in two directions:

- Air deﬂ ectors to be oriented manually

- Horizontal louver, can be oriented only by means of the remote controller

ORIENT THE AIR DEFLECTOR:

- Turn the air deﬂ ector as indicated in the ﬁ gure

- Both in Heating and Cooling mode it is advisable for the air ﬂ ow not to hit people directly.

MOTORIZED HORIZONTAL LOUVER:

- Never orient the motorized horizontal louver manually. Any manual operation on the louver may cause damage in the system and cause malfunctioning. Adjust the horizontal louver using only the remote controller.

MAINTENANCE AND CARE

OPERATION TIPS

WARNING

- Disconnect and lock off the power before making any repair or any services.

- Sharp edges and coil surfaces are a potential injury hazard avoid contact with them.

MAINTENANCE

If you plan to idle the unit for a long time, performed the following:

1. Operate the fan motor to dry off the unit.

2. Stop the air conditioner and disconnect power.

3. Remove the batteries from the remote controller.

CHECK BEFORE OPERATION

1. Check the wiring if is not broken off or disconnected.

2. Check the air ﬁ lter if is installed and the air outlet is not blocked.

PULIZIA DEL VENTILCONVETTORE

1. Pulire la parte esterna ogni settimana, con un panno asciutto bagnato con acqua e detergente delicato, evitare l’uso di altri detergenti.

2. Il telaio con griglia con il pannello può essere rimosso, pulirlo con acqua tiepida non superiore ai 40°C e asciugare con un panno asciutto.

3. Non usare un panno trattato chimicamente o uno spolverino per pulire l’unità.

4. Non usare benzene, solventi, lucidanti chimici o simili solventi per pulire. Possono scolorire, screpolare o deformare la superﬁ cie plastica.

CLEANING AIR FILTERS

Dirty and clogged ﬁ lters reduce the cooling efﬁ ciency of the unit, it is recommen- ded to clean the ﬁ lters once every 2 weeks or weekly.

1. Open the deco panel by grasping the rounded groove and pulling it towards you.

2. Hold the tabs of air ﬁ lter and raise it slightly, then pull it downwards.

3. Clean the air ﬁ lters with vacuum cleaner or wash it with water then dry it up in the cool place.

4. Do not use benzene, thinner, polishing chemical or similar solvents for cleaning. These may cause the plastic surface to crack or deform.

5. Install the air ﬁ lter vise versa of dismantling procedure. The correct ﬁ lter side shown the “FRONT” letter towards you.

DThe following events may occur during normal operation.

A PECULIAR SMELL COMING FROM THE UNIT

Odors present in the room, such as those from the carpet, furniture or smoke maybe emitted from the unit.

HISSING SOUND HEAR DURING OPERATION

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

IMPORTANT INFORMATIONTROUBLE SHOOTING GUIDE

If the unit appears to be malfunctioning, check the following points before calling for service.

PROBLEM

1. Air conditioner doesn’t operate at all.

PROBLEM CAUSE

1. Is the power been shut down or power failure?

2. Is the wiring connection loose?

3. Is the power leakage protection in operation?

4. Is Fuse blown or Circuit breaker open?

REMEDY

1. Wait for power resume.

2. Tighten the connection.

3. Reset the power leakage protection.

4. Replace fuse or reset the circuit breaker.

PROBLEM

2. Insufﬁ cient Cooling or Heating.

PROBLEM CAUSE

1. Is the set temperature is suitable?

2. Is air inlet or outlet obstructed?

3. Are ﬁ lters are dirty?

4. Is there any other heat source in the room?

5. Is there a large number of people in the room?

REMEDY

1. Reset in suitable set temperature

2. Remove objects that obstruct the air inlet and outlet.

3. Clean ﬁ lters and other part.

PROBLEM

3. Wireless remote controller is not functioning.

PROBLEM CAUSE

1. Is the remote control unit out of effective distance to the indoor unit?

2. Are there any obstruction between the remote controller and signal receptor?

3. Is the battery dryout?

REMEDY

1. Use the remote controller in sufﬁ cient distance.

2. Remove or clean the obstruction.

3. Replace with new batteries.

PROBLEMS THAT NEEDS QUALIFIED PERSONNEL ASSISTANCE.

PROBLEM

1. Air conditioner doesn’t run.

PROBLEM CAUSE

1. Faulty contactor, relay and fan motor capacitor.

2. Control board not functioning.

3. Terminal loose.

REMEDY

1. Replace faulty components.

2. Check the cause of malfunctioning and replace control board, if necessary.

3. Check and retighten.

PROBLEM

1. E1 blinking

2. E2 blinking

3. E3 blinking

PROBLEM CAUSE

1. Room Sensor error is activated.

2. Freeze Sensor error is activated.

3. Inlet water Sensor error is activated.

REMEDY

1. Check all sensors for loss connection and replace defective sensors if necessary.

PROBLEM

3. E4 blinking

PROBLEM CAUSE

1. Inlet water temperature fault is activated because;

- in cool mode the starting temperature is ≥20°C.

- in heat mode the starting temperature is ≤35°C.

REMEDY

1. Check the inlet water temperature whether right to start in cool/heat mode.

- in cool mode the inlet water temperature is ≤15°C.

- in heat mode the inlet water temperature is ≥ 40°C.

The unit is connected to the power supply. Operations performed by persons without the required technical skills can lead to personal injury to the operator or damage to the unit and surrounding objects.

MALFUNCTIONING

- In the case of malfunctioning remove the power to the unit then repower it and start up the unit again. If the problems occur again, call services personnel promptly.

- Air conditioner must be operated comply with the Power, Amps and Hz noted in the unit name plate. Failing to do so, it may cause permanents damage to the unit.

- The ground must be connected. Do not connect the ground wire to water pipes, gas pipes, lighting rods, and telephone ground wire.

- Select the most appropriate temperature to provide maximum comfort in room. Keep the room cooler than outside about 5°C. Careful choice of the room temperature will lead to energy savings.

- Do not leave windows and doors open while operating the air conditioner. During operation always leave the ﬁ lters on the unit otherwise the dust in the air could soil the surface of the evaporator coil.

- The air direction can be adjusted appropriately. The air coming out of the unit must not strike people directly it could cause cold sensation and resulting discomfort. Adjust the air deﬂ ector by hands and use the remote control to adjust the horizontal louver. Do not put anything in the air inlets or outlet slot. this could cause injury to the people and damage to the fan. Splashing water on the air conditioner can cause an electrical shock and malfunction on the unit.

Due to continuous research and development, the speciﬁ cation may change without prior notice.
