1. If ambient temperature is too
high, power off the unit and then
energize it for operation after the
ambient temperature drops to be-
low 35°.
2. Check if the evaporator and con-
denser are blocked by some ob-
jects. If yes, take away the ob-
jects, power off the unit and then
energize it for operation.
3. If the malfunction still occur,
please contact our after-sales ser-

12. VENTING KIT ACCESSORIES
If the unit is to be used exclusively in one space, the cooling efficien-
cy will be enhanced by using the following venting kit accessories.
USING EXHAUST DUCT SET (Fig. H)
1. Prepare the below accessory.
H1 Exhaust duct hose adapter nozzle (Fix to unit)
H2 Exhaust duct hose
H3 Exhaust nozzle (upper) + Exhaust nozzle (lower)
2. To fix the Exhaust nozzle (upper) and the Exhaust nozzle (low-
er) together, press the clasp forcibly into the groove. (Fig. H4)
3. Insert one end of exhaust duct hose (flexible tube) (H2) into
exhaust duct hose adapter nozzle (H1) by turning it counter
clockwise. And install exhaust nozzle (upper + lower) (H3) into
another side of exhaust duct hose. (Fig. H5)
4. Face the side with "TOP" upwards. Insert exhaust duct hose
adapter nozzle into the groove of exhaust outlet until you hear
a sound. (Fig. H6)
5. Place the exhaust hose outdoors. (Fig. H7)
NOTE: Place the unit as close as possible to the window or
door. (H5, H6, H7)
13. Specialist's Manual
Aptitude requirement for maintenance man(repairs should be do-
ne only be specialists).
a. All the work men who are engaging in the refrigeration system
should bear the valid certification awarded by the authoritative
organization and the qualification for dealing with the refrigera-
tion system recognized by this industry.
b. It can only be repaired by the method suggested by the equip-
ment's manufacturer.
If it needs other technician to maintain and repair the appliance,
they should be supervised by the person who bears the qualifi-
cation for using the flammable refrigerant.
Safety preparation work before installation
The safety must be inspected before maintaining the appliances
with the flammable refrigerant for reducing the flammable hazard
to the lowest.
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.
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.
Environment checking

• All maintenance staff and others working in the local area shall
be instructed on the nature of work being carried out. Work in
2
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.
• The area shall be checked with an appropriate refrigerant detec-
tor 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, ade-
quately sealed or intrinsically safe.
• No person carrying out work in relation to a refrigeration 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 in-
stallation, repairing, removing and disposal, during which refrig-
erant 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
3
or ignition risks. "No Smoking" signs shall be displayed.
• If any hot work is to be conducted on the refrigeration equip-
ment or any associated parts, appropriate fire extinguishing
equipment shall be available to hand. Have a dry powder or CO
fire extinguisher adjacent to the charging area.
