SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing an appliance with R32.

Checks to the area
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following precautions shall be complied with prior to conducting work on the system.

Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapor being present while the work is being performed.

General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the work space shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.

Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. no sparking, adequately sealed or intrinsically safe.

Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.

No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and disposal, during which flammable refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be displayed.

Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt consult the manufacturer’s technical department for assistance.
The following checks shall be applied to installations using flammable refrigerants:

• The charge size is in accordance with the room size within which the refrigerant containing parts are installed;
• The ventilation machinery and outlets are operating adequately and are not obstructed;
• If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
• Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;
  • refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance which may corrode refrigerant containing components, unless the components are constructed of materials which are inherently resistant to being corroded or are suitably protected against being so corroded.

Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are advised.

Initial safety checks shall include:

• Those capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• That there no live electrical components and wiring are exposed while charging, recovering or purging the system;
• That there is continuity of earth bonding.

WARNING!
Install the unit in rooms which exceed 4 m².
Do not install the unit in a place where inflammable gas may leak.

NOTE!
The manufacture may provide other suitable example or may provide additional information about the refrigerant odour.

• When the unit operates in the heating operation, drying operation, once the coil temperature sensor senses the temperature of the evaporator is below 40℃ and the differential temperature between coil temperature and room temperature is below 19℃ after the compressor operation for 20minutes, the unit start defrosting for 5 minutes and the power indicator blinking.

Overload Protection
In the event of a power loss, to protect the compressor there is a 3-minute delay until the compressor restarting.

DRAINAGE
Manual drainage:

1. When the machine stops after the water is full, please unplug the power plug.
   Notes: Please move the machine carefully, so as not to spill the water in the water pan at the bottom of the body.

2. Place the water container below the side water outlet behind the body.

3. Unplug the water plug, the water will automatically flow into the water container.

Notes:

1. Keep the water plug properly.

2. During drainage, the body can be tilted slightly backwards.

3. If the water container cannot hold all the water, before the water container is full, stuff the water outlet with the water plug as soon as possible to prevent water from flowing to the floor or the carpet.

4. When the water is discharged, stuff the water plug.
   Notes:

5. Restart the machine after the water plug and drainage cover are installed, otherwise condensate water of the machine will flow to the floor or the carpet.

Continuous drainage
The self-evaporating system uses the collected water to cool the condenser coils for better efficient performance. It is no need to empty the drainage tank in cooling operation except in heating operation, drying operation and high humidity conditions. The condensate water evaporates at the condenser and evacuated through the exhaust hose.
For continuous operation or unattended operating in drying operation, please connect the attached drain hose to the unit. Condensate water can be automatically flow into a bucket or drain by gravity.

• Switch off the unit before operating.
• Remove the plug of the water outlet opening, and keep it in safe area.
• Securely and properly connect the drain hose and make sure it is not kinked and clear of obstruction.
• Place the outlet of hose over a drain or bucket and ensure that water could freely flow out of the unit.
• Do not submerge the end of hose into water; otherwise it can cause “Air Lock” in the hose.

|

---|---
To avoid water spillage:

• As the negative pressure of condensate drain pan is large, tilt the drain hose downward toward the floor. It is appropriate that the degree of inclination should exceed 20 degrees.
• Straighten the hose to avoid a trap existing in the hose.

CLEANING AND CARE

CLEANING THE AIR FILTER (every two weeks)
