Unit Installation
66
Transparent drain hose should be selected so that it is able to clearly see the flow status. Length of
the drain hose is generally about 150mm. The hose should be connected to the unit and the drain pipe
by the pipe clamps for further maintenance but not by glue. Besides, the drain house should be
anti-shock.
1.4 Insulation
The insulation is used for thermal insulation. The mostly used insulation is loose fiber and porous
material. For FCU, the mostly used insulation is PEF and foam rubber.
PEF foam plastic
Using the advanced foaming technology, it is soft, light-weighted, fire-proof, and corrosion-proof. It
can be widely applicable to insulation for buildings, cold storages, air conditionings and low-temperature
pipes. Its operation is easy and simple.
Foam Rubber
It is mainly made of buna-n rubber and PVC. It is a high-foaming closed-cell elastic body, with small
density, low thermal conductivity coefficient, good weatherability, shock-absorbed, noise-absorbing,
flame-retardant and water-proof. Besides, its temperature range is wide, and no pollutant would be
generated during production and use. It is an environment friendly product.
B1 or above nonflammable rubber foam
pipe
The thickness should be enlarged when it is used under moisture
environment.
