Pipe Joints Thermal Insulation:
Wrap the pipes joints with thermal insulation
materials and then wrap with a vinyl tape.

Pipes Thermal Insulation:
Fresh air hose:
Fresh air hoses are divided into three types: left outlet
hoses (Figure 1), right outlet hoses (Figure 2) and
rear outlet hoses (Figure 3).
For the left outlet hoses, wrap them tightly with the
bandage in such a way of the fresh air hose and
power cord on the top, the connecting pipe in the
middle, and the drain hose on the bottom (Figure 1);
For the right outlet hoses, wrap them tightly with the
bandage in such a way of the connecting pipe and
power cord on the top, the fresh air hose in the middle,
and the drain hose on the bottom (Figure 2); For the
rear outlet hoses, the fresh air hose exits from the wall
hole with a diameter of 80mm, and other hoses exit
from the wall hole with a diameter of 65mm after being
wrapped tightly with the bandage (Figure 3).

For the rear outlet hoses, directly connect the through
-wall hose with the cover plate of the fresh air cavity
(Figure 4); For the left outlet hoses, first connect the
elbow of the fresh air hose with the joint of the fresh
air cavity (Figure 5), then rotate the elbow of the
through-wall hose clockwise along the thread direction
for removing (Figure 6) (The elbow will not be used
any longer), and finally rotate the through-wall hose
counterclockwise to the other end of the fresh air hose
(Figure 7); For the right outlet hoses, first remove the
sheet metal part installed on the base with a
screwdriver, then connect the elbow of the fresh air
hose with the joint of the fresh air cavity (Figure 8),
then rotate the elbow of the through-wall hose
clockwise along the thread direction for removing
(Figure 6) (The elbow will not be used any longer),
next rotate the through-wall hose counterclockwise to
the other end of the fresh air hose (Figure 7), and
finally fix the sheet metal part on the base after
wrapping the hoses Figure 9)
Note:
Adjust the angle of the through-wall hose and the fresh air
hose, so that the opening part of the rain cover of the through-
wall hose extends out of the room downwards. When the
opening part of the rain cover cannot face downwards, please
properly rotate the joints at both ends of the through-wall hose
to ensure that the opening part of the rain cover of the through-
wall hose faces downwards (after adjustment, wrap the rain
cover, rotating joint and winding hose screw-in positions with
electrical tape to ensure sealing and prevent the rain cover and
the rotating joint from falling off during rotation) to prevent
water from entering the through-wall hose in rainy days.

Lengthening of the fresh air hose (Figure 10): Take
two fresh air hoses, cut one of them at the hose
body and elbow position A with a paper cutter, cut
the other one at the position B according to the
required length, with the part with bent joint
reserved, and conduct the plug connection of hose
body with straight joint of the first fresh air hose
and the hose body with the bent joint of the second
fresh air hose. After completion, wrap the plug
connection position tightly with electrical tape to
ensure sealing.
Shortening of the fresh air hose (Figure 11): untie
the adhesive tapes between the thermal insulation
layer and the straight joint, and between the
straight joint and the fresh air hose body in the
fresh air hose position B to separate the straight
joint from the hose body. In the required installation
length C, cut off the hose body, and conduct plug
connection of the remaining hose body with the
a
c
elbow and the straight joint. After completion, wrap
d
the plug connection position tightly with electrical
tape to ensure sealing.
Shortening of the through-wall hose (Figure 12):
Rotate clockwise to screw off the joint or rain cover,
cut off the winding hose according to the required
length, and then screw on the joint or rain cover
counterclockwise. After adjusting the position, wrap
the rain cover, rotating joint and winding hose plug
connection positions with electrical tape
respectively
Note:
1. It must be ensured that the fresh air hose indoors is
provided with the thermal insulation layer; the straight joint
and part of the through-wall hose body are placed in the wall
body; and the opening of the rain cover extends out of the
room downwards.
2. The fresh air inlet shall be far away from cold and heat
sources, high humidity environment, pollution sources and
places containing harmful gases and corrosive gases.
3. The nominal fresh air volume marked on the product
nameplate and manual is measured under laboratory
conditions according to the accompanying 0.5m rear outlet
hoses.
