Preparation before use

Note

Preset

Safeguarding the environmentThis applianc e is made of rec y clable or re-usabl e material. Scrapping must be carried out incompliance with local waste disposal regulations. Before scrapping it, make sure to cut off the mainscord so that the appliance cannot be re-us ed.For more d etailed information on handling and recycling this product, contact your local authoritieswho d e al with the separate collection of rubbish or the shop where you bought the appliance.SCRAPPING OF APPLIANCEThis appliance is marked according to the European Directiv e 2012/19/EC, Waste Electrical andElectronic Equipment (WEEE).This marking indicates that this product should not be disposedwith other household wast e s throughout the EU. To prevent possibleharm to the environment or human health from uncontrolled wastedisposal,recycle it responsibly to promote the sustainable reuse ofmaterial resources. To return your used devic e , please use the r eturnand collection systems or contact the retailer where the product waspurchased. They can take this product for environmental safe recycling.

• When charging refrigerant into the system, make sure to charge in liquid state,if therefrigerant of the appliance is R41 QA.Otherwise, chemical composition ofrefrigerant (R41 0A) inside the system may change and thus affect performance ofthe air conditioner.• According to the character of refrigerant (R410A,the value of GWP is 2088), thepressure of the tube is very high, so be sure to be careful when you install and repairthe appliance.• If the supply cord is da maged, it must be replaced by the manufacturer, itsservice agent or si milarly quali fied persons in order to avoid a hazard.• The air conditioner must be installed by a professional engineer.• The temperature of refrigerant circuit will be high, please keep theinterconnection cable away from the copper tube .

Before using the air conditioner, be sure to check and preset the following.• Remote Control presettingEach tim e after the remote control is replaced with new batteries or is energized, re mote control auto presetting heat pump.If the air conditioner you purchased is a Cooling Only one, heat pump remote controller can also be used.• Back-light function of Remote Control(optional)Hold down any button on remote control to activate the back light.

Note: When installing the pipe at the directions1,2 or 4, saw the corresponding unloading pieceoff the indoor unit base.

• Put the piping (liquid and gas pipe) and cables through the wall hole from outside or put them throughfrom inside after indoor piping and cables connection is complete to connect to the outdoor unit.• Decide whether to saw the unloading piece off in accordance with the piping direction.(as shown below)

Indoor unit installation1. Installing the Mounting Plate

Note: The shape of your mounting plate may be different from the one above, but the installation method is similar.Note: As the above figure shown, the six holes matched with tapping screw on the mounting plate must be used tofix the mounting plate, the others are prepared.

3. Indoor Unit Piping Installation

2. Drill a Hole for Piping• Decide the position of the hole for piping according to thelocation of mounting plate.• Drill a hole in the wall. The hole should tilt a littledownward toward outside.• Install a sleeve through the wall hole to keep the walltidy and clean.

• Decide an installing location for the mounting plate according to the indoor unit location and piping direction.• Keep the mounting plate horizontal with a horizontal ruler or dropping line.• Drill holes of 32mm in depth on the wall for fixing the plate.• Insert the plastic plugs to the hole, fix the mounting plate with tapping screws.• Inspect if the mounting plate is well fixed. Then drill a hole for piping.

Installation instructions• Piping Joints Thermal Insulation:Wrap the piping joints with thermalinsulation materials and then wrapwith a vinyl tape.

• Piping Thermal Insulation:a. Place the drain hose under the piping.b. Insulation material uses polythene foam over 6mm in thickness. Note: Drain hose is prepared by user.

• Do not arrange the drain pipe in a way that leaves it twisted, stickingout or waving around. Do not immerse the end of it in water.

• If an extension drain hose is connected to the drain pipe, make sureto insulated when passing along the indoor unit.

• When the piping is directed to the right, piping, powerCord and drain pipe should be thermal insulated andfixed onto the back of the unit with a piping fixer.

Piping Connection:

a. Connect indoor unit pipes with two wrenches. Pay special attentionto the allowed torque as shown below to prevent the pipes, connectorsand flare nuts from being deformed and damaged.

If not possible, connect appliance to a double-pole switching device with contactseparation of at least 3 mm2 placed in an accessible position even after installation.



• Indoor UnitConnect the power cord to the indoor unit by connectingthe wires to the terminals on the control board individuallyin accordance with the outdoor unit connection.Note: For some models, it is necessary to remove the cabinet toconnect to the indoor unit terminal.

• Outdoor Unit1) Remove the access door from the unit by looseningthe screw. Connect the wires to the terminals on thecontrol board individually as follows.2) Secure the power cord onto the controlboard with cable clamp.3) Reinstall the access door to the original positionwith the screw.

4) Use a recognized circuit breaker for 24K model betweenthe power source and the unit. A disconnecting device toadequately disconnect all supply lines must be fitted.

4. Connecting of the Cable

CAUTION1. Never fail to have an individual power circuit specifically for the air conditioner. As for the method ofwiring, refer to the circuit diagram posted on the inside of the access door .2. Comfirm that the cable thickness is as specified in the power source specification.3. Check the wires and make sure that they are all tightly fastened after cable connection.4. Be sure to install an earth leakage circuit breaker in wet or moist areas.

Installation instructionsAir purgingThe air which contains moisture remaining in the refrigeration cycle may cause a malfunction on thecompressor. After connecting the indoor and outdoor units, release air and moisture from the refrigerantcycle using a vacuum pump, as shown below.

Note: To protect the environment, be sure not to discharge the refrigerant to the air directly.

How to Purge Air Tubes:(1) Unscrew and remove caps from 2 and 3-way valves.(2) Unscrew and remove cap from service valve.(3) Connect vacuum pump flexible hose to the service valve.(4) Start vacuum pump for 10-15 minutes until reaching a vacuum of 10 mm Hg absolutes.(5) With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop the vacuum pump.(6) Open 2-way valve , 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid soap or an electronic leak detector.(7) Turn 2 and 3-way valves stem to fully close the valves. Disconnect the flexible vacuum pump hose.(8) Replace and tighten all valve caps.
