Don’t spray or smear any oil paint or insecticide on the surface of unit, otherwise, re may be leaded.
◆
Do not ret the conditioner. Please contact the agency or prefect ional personnel to repair or move the
◆
conditioner.
An all-pole disconnection switch having a contact separation of at least 3mm in all poles should be
connected in xed wiring.
Note!:
Please check and make sure that the cord, drainage pipe and tubes are connected in the correct way to

and to prevent electric shock. Please don’t connect the earthing line with the gas pipe, water pipe, lightening
rod or the connecting line of telephone.
The air conditioner should be turned off at least after 5 mins’ operation; otherwise it would affect the

★
1. Obstruct should put away from the intake or outlet vent of the indoor unit so that the airow can be
blown though all the room.
2. Make sure that the installation had accord with the requirement of the schematic diagram of installation
spaces.
3. Select the place where can stand 4 times of the weight of the indoor unit and would not increase the
operating noise and oscillate.
4. The horizontally of the installation place should be guaranteed.
5. Select the place where easy drain condensated coagulated water, and easy connect with outdoor unit.
6. Make sure that there are enough space for care and maintenance. Make sure that the weight between
the indoor unit and ground is above 1800mm.
7. When installing the steeve bolt, check if the install place can stand the weight 4 times of the unit’s. If
not, reinforce before installation. (Refer to the install cardboard and nd where should be reinforced)
Note!
There will be lots of lampblack and dust stick on the acentric, heat exchanger and water pump in dining
room and kitchen, which would reduce the capacity of heat exchanger, lead water leakage and abnormal
operation of the water pump. The following treatment should be taken under this circumstance:
1. Ensure that the smoke trap above cooker has enough capacity to obviate lampblack to prevent the
indraft of the lampblack by the air conditioner.
2. Keep the air conditioner far from the kitchen so that the lampblack would not be indraft by the air
conditioner.
Important notice:

outlet vent by bolt.
3 Adjust the unit to the suitable install place. (Refer to the g.3)
4 Check if the unit is horizontal.
Inner drainage pump and bobber switch are included in the indoor unit, check if 4 angle of every unit
◆
are horizontal by water lever. (If the unit is slant toward the opposite of the coagulate water ow, there may be
malfunction of the bobber switch and lead water drop.)
5 Backout the gasket anchor board used to prevent gasket break off and tighten the nut on it.
6 Backout the install cardboard.
Fig.4
Note!
Please do tighten the nuts and bolts to prevent air conditioner break off.
Connection of the refrigerant pipe
★
When connect the pipe to the unit or backout it from the unit, please do use both spanner and torque
◆
wrench. as shown in g.5.
When connect, smear both inside and outside of the are nut with freeze motor oil, screw it by hand
◆
and then tighten it with spanner.
Refer to form 1 to check if the wrench had been tightened (too tight would mangle the nut and lead
◆
leakage).
Examine the connection pipe to see if it had gas leakage, then take the treatment of heat insulation, as
◆
shown in the g.5.
Only use median sponge to entwine the wiring interface of the gas pipe and heat preservation sheath of
◆
the gas collection tube.
