3.Clean the upper filter screen frame
Unscrew one screw fixed by EVA filter net and back shell with screwdriver, and take
out EVA filter net.
Put the EVA filter screen into warm water with neutral detergent (about 40
and dry it in the shade after rinsing clean.
VIII. Unit Storage:
1: Unscrew the drainage cover, unplug the water plug, and discharge the water in
the water pan into other water containers or directly tilt the body to discharge the
water into other containers.
2: Turn on the unit, adjust it to low-wind ventilation mode, and maintain this state
until the drainage pipe becomes dry, so as to keep the inside of the body in a dry
state and prevent it from mildewing.
3: Turn off the unit, unplug the power plug, and wrap the mains power cable around
the wrapping post; install the water plug and the drainage cover.
4: Remove the exhaust pipe and keep it properly.
5: Cover the unit with a plastic bag. Store the unit in a dry place, keep it out of the
reach of children, and take dust control measures.
6: Remove batteries from the remote control and keep them properly.
Note: Ensure that the body is placed in a dry place and keep all components
properly.
IX.Troubleshooting
1. Information on servicing
1) 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 minimised. For repair to
the refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
2) 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.
3) 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 workspace shall be sectioned off. Ensure that the conditions within
the area have been made safe by control of flammable material.
4) 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. non-sparking, adequately sealed or
intrinsically safe.
5) 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.
6) 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
