V. Installation Method
Installation method of elbow: point the turning of the elbow to the dent of the detachable
elbow base on the machine, insert it in and rotate it anticlockwise. The elbow is in place
when a sound of crack is heard (Fig.1).
Hot Exhaust
Pipe
Cold Exhaust
Pipe

Installation method of cold exhaust pipe: point the turning of the cold exhaust pipe to the
dent of the cold exhaust pipe, insert it in and rotate it to the left to make it in place (Fig.1).
(Fig. 1)
Installation of hot exhaust pipe: insert the hot exhaust pipe in the heat vent. Do install it in
place to guarantee stable and firm hot exhaust pipe (Fig.2).

(Fig. 2)
Change of Connection of Power Line

department to avoid danger.
VI. Installation Method of Extended Hot Exhaust Pipe
Install extended pipe to exhaust the heat to outdoors.
Ask professional to cut a hole on the wall to install the hot exhaust pipe.
Please do guarantee smooth heat extraction of the hot exhaust pipe.

Please do not fall foreign object in the hot exhaust pipe.
The outdoor opening of the hot exhaust pipe shall be equipped with rainwater-
proof backflow device (or bend a certain angle downward directly).
※ Extended hot exhaust pipe shall be separately purchased from the Company. The
specification shall be Φ160x3m.
Please ensure smooth heat extraction of the hot exhaust pipe.

Please do not fall foreign object in the hot exhaust pipe. The outdoor opening of the hot
exhaust pipe shall be equipped with rainwater-proof backflow device (or bend a certain
angle downward directly).
※ Extended hot exhaust pipe shall be separately purchased from the Company. The
specification shall be Φ160x3m.
Method of Cutting of Extended Pipe
Please cut the extended pipe based on the extended length needed.
As is shown in the figure, separate the exhaust pipe from the groove with a flathead
screwdriver or other sharp tools at where it is supposed to be cut, and cut it off with pliers
or scissors.
Method of Reducing the Diameter of Extended Pipe
Rotate the exhaust pipe clockwise to reduce the diameter of pipe opening.

Method of Connecting Extended Pipe
Detach the joint of the hot exhaust pipe and cover the extended pipe outside the hot
exhaust pipe. Screw the end tight and cling to it.
Use adhesive tape to fixate it if necessary. Use binder to fixate the attached pipe opening
of the extended hot exhaust pipe.
VII. Operation Method
Operation Method and Blast Capacity Choosing
Rotate the selecting switch on the cover of the machine to or and the compressor

immediately launches refrigeration. In the meantime, start the draught fan to blow air out.
The blast capacity has or for customer to choose from.
When the switch is rotated to “0”, the machine is off and stops running.
Attention
Please turn the selecting switch off and cut the power off before moving the machine.
When the machine is off, it may be restarted after 3 minutes.
Compressor Overheat and Overload Protection
Overly high or low voltage and overly high environment temperature may cause the
compressor to overhead and overload. To protect the compressor, the overload protector
will be activated to cut the power of the compressor off.
Attention
When the overload protector is activated, the machine only blows out natural wind but
does not refrigerate. If the overload protector is activated frequently, please find out and
eliminate the cause before using the machine.
Range and Operation of Adjustment of Air-out Direction
Cold air pipe may rotate left or right to 360 degrees (hot air pipe is installed).
Cold air pipe may be moved up or town to 150 degrees.
The range of adjustment angle for hot air pipe is 45 degrees.

Attention
Please adjust the cold exhaust pipe in advance and use the air-out direction of the hot exhaust
pipe later. When adjusting the air-out angle of cold exhaust pipe, please grip the elbow for
adjustment and do not hold the cold exhaust pipe directly.
VIII. Water Tank
Method of using water tank: when the water in the tank and the end face on the tank

handle are parallel, set the gear to 0, pour the water out and reinstall the water tank. Choose a
gear to make it work properly.
Attention: Please do not move the machine when the water is full. Pour the water before
moving it.
IX. Drainpipe (Optional)
Condensate water may be discharged from the drainpipe directly.
Method: take the water tank out and put the drainpipe directly on the outfall of the tank to
cross the round hole on the corresponding side plate.
X. Requirement for Machine Operating Site
Special Reminder for Users:
When the machine is running, both the filter screen and the cold air pipe shall be
