Fault Checkup
Please check the following when consigning repair service:
Symptoms Reasons
All these are not problems
• Water ow sound
Water ow sound can be heard when starting operation,
during operation or immediately after stopping operation.
When it starts to work for 2-3 minutes, the sound may
become louder, which is the owing sound of refrigerant or
the draining sound of condensed water.
• Cracking sound
During operation, the air conditioner may make the
cracking sound, which is caused from the temperature
changes or the slight dilation of heat exchanger.
• Terrible smell in outlet air
• Flashing operating
indicator
When switching it on again after power failure, turn on the
manual power switch and the operating indicator ashes.
• Awaiting indication
It displays the awaiting indication as it fails to perform
refrigerating operation while other indoor units are
in heating operation. When the operator set it to the
refrigerating or heating mode and the operation is opposite
to the setting, it displays the awaiting indication.
• Sound in
• shutdown indoor
• unit or white
• steam or cold air
To prevent oil and refrigerant from blocking the shutdown
indoor units, refrigerant ows in the short time and make
the sounds of refrigerant owing. Otherwise, when other
indoor units performs heating operation, white steam may
occur; during refrigerating operation, cold air may appear.
When the conditioner is powered on, the sound is made
due to the resetting of the expansion valve.
Check if it is in the state of Timer-ON and Timer-OFF.
• Failure to work Check if there is a power failure.
Check if the manual power switch is turned off.
Check if the supply fuse and breaker are disconnected.
Check if the protective unit is working.
Check if refrigerating and heating functions are selected
simultaneously with the awaiting indication on line control.
• Bad cooling & heating
effects
Check if air intake port and air outlet port of outdoor units are
blocked.
Check if the door and windows are open.
Check if the ltering screen of air cleaner is blocked with
sludge or dust.
Check if the setting of wind quantity is at low wind.
Check if the setting of operation is at the Fan Operation state.
Check if the temperature setting is proper.
During operation, the air conditioner may make the cracking
sound, which is caused from the temperature changes or
the slight dilation of heat exchanger.
Under the following circumstances, immediately stop the operation, disconnect the manual
supply switch and contact the after-service personnel.
• When buttons are inexible actuated;
• When there are foreign objects and water in the refrigerator;
• When it cannot still be operated after removing the operation of protective unit;

Please use the standard tools according to the installation requirements.
The standard attached accessories of the units of this series refer to the packing list; prepare
other accessories according to the requirements of the local installation point of our company.
1.Choose the suitable installation location. Indoor units should be installed in places with
the environment of even circulation of cool and warm blows. The following places should
be avoided.
Places with high salinity (beach), high sulfureted gas(such as the thermal spring regions where
copper tubes and soft soldering are easy to be eroded), much oil(including mechanical oil) and
steam; places where organic substance solvent is frequently used; places where machines
generate the high frequency electromagnetic wave (abnormal condition will appear in the control
system); places where there is high humidity exists near the door or windows (dew is easily
formed); and places where the special sprayer is frequently used.

Indoor Units
1. The distance between wind outlet port and the ground should not be more than 2.7m.
2. Select appropriate places for installation where the outlet air can be spread to places all over
the house and arrange proper locations for connecting pipes and lines as well as the drainpipe
to the outdoor.
3. Ceiling construction must be hard enough to hold the weight of the unit.
4. Make sure that the connecting pipe, the drainpipe and connecting guide line can be put into
walls to connect the outdoor units.
5. It is recommended to make the connecting pipe between the outdoor and indoor units and the
drainpipe are as short as possible.
6. Please read the attached installation instruction of outdoor units for regulation of lling amount
of refrigerant if necessary.
7. The connecting ange should be checked by users.
8. Those electrical appliances such as television, instruments, devices, artwork, piano, wireless
equipment and other valuables should not be placed under the indoor unit as to prevent
condensate from dropping into them and causing damage.
2.The following steps can be taken after selecting the installation place:
(1) Cut a hole in the wall and insert connection pipe and connecting wires
through a locally purchased PVC pipe. The hole should be inclined slightly
downward with an inclination of at least 1/100 (see Figure 1).
(2) Before cutting the hole, ensure no pipe or rebar is placed behind the cutting
position. Avoid cutting a hole at the place of wires or connection pipes.
(3) Hang the unit on a horizontal and rm roof. If the unit base is not stable, it may cause noise,
vibration or leakage.
(4) Support the unit firmly and change the shapes of connection pipe, connecting wires and
drain pipe to make them easily get through the hole.
