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

4. 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.

5. 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 toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i. e. non-sparking, adequately sealed or intrinsically safe.

6. Presence of fire extinguisher
   If any hot work is to be conducted on the refrigerating 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.

7. No ignition sources
   No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work 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 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.

8. 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.

9. Checks to the refrigerating 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 actual REFRIGERANT CHARGE 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;
   • refrigerating 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.

10. 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:

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

11. Repairs to sealed components

12. During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.

13. Sealed electrical components shall be replaced.

14. Repair to intrinsically safe components

    • Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components must be replaced.
    • Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak.

15. Cabling
    Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

16. Detection of flammable refrigerants
    Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used. The following leak detection methods are deemed acceptable for all refrigerant systems. Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS, the sensitivity may not be adequate, or may need re- calibration. (Detection equipment shall be calibrated in a refrigerant-free area.)

    • Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the refrigerant employed, and the appropriate percentage of gas (25 % maximum) is confirmed.
    • Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine shall be avoided as the chlorine may react with the refrigerant and corrode the copper pipe-work.
    • If a leak is suspected, all naked flames shall be removed/extinguished.
    • If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut off valves) in a part of the system remote from the leak. Removal of refrigerant shall be according to Removal and evacuation.

17. Removal and evacuation
    When breaking into the refrigerant circuit to make repairs -or for any other purpose-conventional procedures shall be used. However, for flammable refrigerants it is important that best practice be followed, since flammability is a consideration.

    • The following procedure shall be adhered to:
    • safely remove refrigerant following local and national regulations;
    • purge the circuit with inert gas(optional for A2L);
    • evacuate(optional for A2L);
    • continuously flush or purge with inert gas when using flame to open circuit ;and
    • open the circuit .
    • The refrigerant charge shall be recovered into the correct recovery cylinders if venting is not allowed by local and national codes. For appliances containing flammable refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This process might need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems.
    • For appliances containing flammable refrigerants, refrigerants purging shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system (optional for A2L). When the final oxygen-free nitrogen charge is used, the system. The outlet for the vacuum pump shall not be close to any potential ignition sources, and ventilation shall be available.

18. Charging procedures
    In addition to conventional charging procedures, the following requirements shall be followed.

    • Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them.
    • Cylinders shall be kept in an appropriate position according to the instructions.
    • Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with refrigerant.
    • Label the system when charging is complete (if not already).
    • Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM. Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

19. Decommissioning
    Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is essential that electrical power is available before the task is commenced.

20. Become familiar with the equipment and its operation.

21. Isolate system electrically.

22. Before attempting the procedure, ensure that:

  * Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
  * All personal protective equipment is available and being used correctly;
  * The recovery process is supervised at all times by a competent person;
  *  Recovery equipment and cylinders conform to the appropriate standards.
4. Pump down refrigerant system, if possible.
5. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
6. Make sure that cylinder is situated on the scales before recovery takes place.
7. Start the recovery machine and operate in accordance with instructions.
8. Do not overfill cylinders (no more than 80 % volume liquid charge).
9. Do not exceed the maximum working pressure of the cylinder, even temporarily.
10. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed off.
11. Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and checked.

18. Labelling
    Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are labels on the equipment stating the equipment contains FLAMMABLE REFRIGERANT.

19. Recovery
    When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely.When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed. Ensure that the correct number of cylinders for holding the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i. e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure-relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.

The recovery equipment shala l be in good working order with a set of instructions concerning the equipment that is at hand and shall be suitable for the recovery of the flammable refrigerant. If in doubt, the manufacturer should be consulted. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be complete with leak-free disconnect couplings and in good condition.

The recovered refrigerant shall be processed according to local legislation in the correct recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.

If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to make certain that flammable refrigerant does not remain within the lubricant. The compressor body shall not be heated by an open flame or other ignition sources to accelerate this process. When oil is drained from a system, it shall be carried out safely.

Set Up the Drainage

Drain by Internal Pump
The dehumidifier has an internal pump that helps to drain the condensation water freely. When using the pump feature,

• The Gravity Drain Outlet needs to be sealed by the included stopper;
• Connect the drain hose to the Pump Drain Outlet;
• Place the unattached end of the hose in a sink, bucket, pump sump, or out of a window anywhere that water can drain out safely. (Ensure there are no kinks or other obstructions that will stop the water to flow.)

NOTE:

• If you use a bucket or other container for water collection, check it regularly to prevent overflows.
• The drain hose for the water pump can drain vertically up to 16ft. More than 16ft may cause water back up to the pump resulting in leakage.
• If the drain hose is too long, water may not drain completely, which can lead to stagnant water and mildew build up inside the hose.
• Before moving the dehumidifier, please remove the stopper from the Gravity Drain Outlet to completely drain the condensation in the internal water tray to avoid water leakage.

Drain by Gravity
The collected condensation water can be drained by gravity. When using gravity to drain.

• Connect the drain hose to the Gravity Drain Outlet;
• Place the unattached end of the hose to a suitable drainage facility. The drainage facility should be lower than the drain outlet of the dehumidifier. (Ensure there are no kinks or other obstructions that will stop the water to flow.)

Plug in Electrical Cord

IMPORTANT
Please let the dehumidifier sit outside the box for 24 hours before initial plugging in. To properly operate the dehumidifier, please plug it into a GFCl- protected 115-volt outlet with a rating of at least 16 amps. Uncoil the power cord and securely connect it to an appropriate outlet.

Note : When the dehumidifier is first plugged into AC power, the control panel display will light up for a second, which is part of the dehumidifier’s self-diagnosis procedure and no action is required. This indicates that the dehumidifier is functioning correctly and ready to operate effectively. You will still need to press the POWER button to turn the dehumidifier on. If not been operated for over 50 seconds, the control panel will become dime until pressed buttons again.

Understand the Control Panel

The control panel of the dehumidifier features a user-friendly interface with 4 buttons and an LED screen. Press the POWER Button to turn the dehumidifier on. After turning on the dehumidifier, the LED screen will display the readouts. Up Power/Purge

When you are pressing the or button to set the target humidity percentage value, this digital number will turn to display the previous setting value and keep blinking.
• is the temperature readout of the inlet air the dehumidifier detects which is similar to the current room temperature.
•  illuminates when the timer function is enabled and disappears when the timer function is disabled.

Fan Icon:
It illuminates when the fan is running and disappears when the compressor stops running.

Water Droplet Icon :
It illuminates when the compressor is running and disappears when the compressor stops running.

Note:
In the following cases, it is normal if the water droplet icon disappears which means the compressor stops or does not kick in.

• The humidity set-point is NOT at least 5% lower than the room humidity readout value (in this case, please double-check your setting);
• The room humidity level has reached the set-point, so the dehumidifier automatically stops running;
• umidifier was just turned on and may take a few seconds for the compressor to kick in;
• The dehumidifier was restarted in a brief moment, the compressor is under delay protection status.

Defrosting icon : It illuminates when the dehumidifier detects frost on the interior. During defrosting, the fan operates while the compressor does not, and the defrost icon flashes until the frost melts. The dehumidifier will automatically begin to dehumidify and the “Defrost” icon will disappear once the defrosting process is complete.

Note : Frequent defrosting indicates that the room temperature is too low. It is recommended to add heat when the room temperature is lower than 60° F for proper drying.

5. Smart Functions

6. 3 Minutes Compressor Protection Mechanism
   It prevents the dehumidifier from starting immediately after a complete cycle to avoid any potential damage. The compressor will start automatically after a 3-minute delay. During this time, the Fan icon is illuminating continuously on the LED screen and until the compressor kicks in, the water droplets icon illuminates. That’s to say, if the dehumidifier was turned off and then restarted immediately, the compressor will not kick in until 3 minutes later.

7. Auto Defrost
   The compressor cycles off when frost builds up on the evaporator coils and the fan will continue to run until the frost disappears. Meanwhile, the DEFROST icon will light up on the LED screen during the defrosting process.

8. Auto-Restart
   If the dehumidifier shuts off unexpectedly due to power outage, the dehumidifier will restart with the previous function settings automatically when the power resumes.

MAINTENANCE

To avoid possible electric shock, ensure to turn the dehumidifier off and disconnect the plug from the power source before performing any cleaning or maintenance.

1. Cleaning the Dehumidifier
   Clean the dehumidifier housing with a soft damp cloth. Do not submerge or place water on the dehumidifier or control panel. Water may damage the electronic components of the dehumidifier. Do not use chemical solvents such as benzene, alcohol, gasoline or other heavy-duty cleaners. The surface may become damaged or deformed.

2. Cleaning the Air Filter
   The working performance of the dehumidifier will be greatly reduced if the filter becomes blocked. The air filter should be cleaned approximately every 2 weeks and may require more frequent cleaning if there is significant dander or fur in the air. The air filter is located behind the inlet grill.

Follow the steps below to clean the filter :

• Unscrew the hand screw on the top of the inlet grill, open the inlet grill and take the filter out.
• Use a vacuum cleaner with a soft brush attachment to remove any large debris or dust build-up from the filter.
• Wash the filter in lukewarm, soapy water, below 40°C (104° F), or use a neutral cleaning agent.
• Rinse the filter with clean water and dry thoroughly.
• Re-install the filter.

NOTE : DO NOT operate the dehumidifier without a filter because dirt and lint will clog it, hence reducing performance.
