Liquid pipe Insulation meterial Gaspipe
➢
The insulation material at the joint pipe shall be 5~10cm longer than the gap of the insulation
material.
➢
The insulation material at the joint pipe shall be inserted into the gap of the insulation material.
➢
The insulation material at the joint pipe shall be banded to the gap pipe and liquid pipe tightly.
➢
The linking part should be use glue to paste together
➢
Be sure not bind the insulation material over-tight, it may extrude out the air in the material to
cause bad insulation and cause easy aging of the material.
2.9.2 Insulation of Drainage Pipe
2.9.2.1 Operational Procedure of Refrigerant Pipe Insulation
Select the suitable pipe
→
insulation (except joint section)
→
piping layout and connection
→
drainage test
→
insulate the joint parts
2.9.2.2 Purpose of Drainage Pipe Insulation
The temperature of condensate drainage water is very low. If insulation is not enough, it shall
form dew and cause leakage to damage the house decoration.
2.9.2.3 Insulation Material Selection for Drainage Pipe
➢
The insulation material should be flame retardant material, the flame retardancy of the material
should be selected according to the local law.
➢
Thickness of insulation layer is usually above 10mm.
➢
Use specific glue to paste the seam of insulation material, and then bind with adhesive tape. The
width of tape shall not be less than 5cm. Make sure it is firm and avoid dew.
2.9.2.4 Installation and Highlights of Insulation Construction

Always disconnect the power supply before working on the unit.
➢
All electrical wiring must be done according to local and national regulations.
➢
The wiring must be carried out by a certified technician. Improper connection may cause
electrical failure, personal injury and fire.
➢
This unit must use independent circuit and single outlet. Please DO NOT plug other equipment or
chargers into the same outlet. If the circuit capacity is insufficient or the electrical system fails, it will
cause electric shock, fire, unit and property loss.
➢
Connect the power cord to the terminal and secure it with the wiring clamp. Improper connections
may cause fire.
➢
Make sure all wiring is correct and the control box cover is installed correctly. Otherwise, may
cause overheating at the connection points, fire, and electrical shock.
➢
Ensure that main supply connection is made through a switch that disconnects all poles, with
contact gap of a least 3mm (0.118").
➢
DO NOT modify the length of the power cord or use an extension cord.
➢
Connect the outdoor wires before connecting the indoor wires.
➢
Be sure to ground the equipment. The grounding wire shall be away from gas pipeline, water
