Heat Insulation Material Requirements
Copper pipe insulation
① Use the closed-cell foam insulation material, which is rated at a flame retardancy level of B1 and heat resistance of over
120℃.
② Thickness of the insulation pipe:
1. When the diameter of the copper pipe is equal to or greater than 15.9mm, the insulation thickness is at least 20mm.
2. When the diameter of the copper pipe is equal to or smaller than 12.7mm, the insulation thickness is at least 15mm.
③ For insulation of the outdoor copper pipe, the wall thickness of insulation pipes for winter heating systems is generally
thickened to over 40mm in regions with severe cold. For insulation of the indoor gas pipe, the wall thickness of insulation
pipes is usually greater than 20mm.
[ Caution ]
The materials and specifications of insulation materials must meet national or industry standards.

Check Before Installation
Unpacking Check
Before installation, check whether the packing materials are in good condition,
①
whether the accessories that come with the product are complete, whether
the air conditioner is intact, whether the surfaces of the heat exchanger and
other parts have become worn, and whether there are oil stains on the check
valve of the unit.
Check the two sealing nuts of the refrigerant pipe, and observe whether the
②
red dot on the surface of the sealing nut of the gas pipe bulges. If it bulges, the
pipe is well sealed; if it retracts, the line is leaking, and you need to contact
your local dealer.
Check the machine model before installation.
③
After IDU and ODU inspection, pack them with plastic bags to avoid intake of
④
foreign matters.
Refrigerant Connecting Piping Installation
1
Length and Level Difference Requirements for the Pipe Connections of IDU and ODU
Different ODUs have different requirements for length and level differences for the piping. Refer to the Installation &
Owner's Manual attached with the ODU.
[ Warning ]
During the installation of the connecting pipes, do not allow air, dust, and other debris to penetrate the piping system,
and make sure the interior of the pipes is dry.
Install the connecting pipes only when the IDUs and ODUs are secured.
When installing the connecting pipes, record the actual installation length of the liquid pipe on the spot so that additional
refrigerant can be added.
The copper pipes must be wrapped with thermal insulation materials when they are installed.
In the event of refrigerant gas leakage during operation, please ventilate immediately.
