DC Inverter Air
2) The configuration of air conduit joint on the site may not reduce its effective cross section;
3) The support and hanger of air conduit cannot be set up at air port, valve, manhole and automatic
control mechanism; the boom/suspender shall not be directly fixed on the flange;
4) The configuration of air conduit joint on the site may not reduce its effective cross section;
5) Deviation standard for hoisting operation of air conduit
Horizontal Installation Vertical Installation
Open‐type Installation δ≤3mm/m Δ≤20mm δ≤2mm/m Δ≤20mm
Concealed Installation Correct position, free from any obvious deviation
δ— Deviation per meter; — total deviation
6) The support and hanger of heat‐preservation air conduit shall be located outside of the insulation
layer, and may not damage the insulation layer;
7) The spacing of support and hanger shall comply the following provisions unless otherwise required
in the design:
Diameter(long side) size<400mm Diameter(long side)≥ 400mm
Horizontal spacing ≤4mm ≤3mm
Vertical spacing ≤4mm, each riser shall be equipped with less than 2 fixed parts
6) Installation of Drain Pipes
Warning:
Must install drainpipes according to the following figure, avoiding generating condensed water and leakage
water.
a. Assemble the main body according to the Figure.
b. The opening of drainpipes can be installed on the leftside or the right side . Could remove the drain stopper
and put it on the leftside or the right side.
c. For the best effect, should keep pipes as short as possible. Tilt the pipes to ensure the flow of fluid.
d. Make sure the drainpipes have admirable heat insulation.
e. It is necessary to install a trap near the opening of the drainpipe, so that when the machine is working, the
pressure in the inside of the machine is lower than atmospheric pressure. If there isn't an elbow, the water will
splash and the pipe will produce a bad smell.
f. keep straightness of drainpipes so as to remove dirt.
g. Seal the drainpipe on the other side of the machine, then wrap up the drainpipe in the heat‐barrier materials.
h. Put water into the drain pan to test whether the water can be discharged swimmingly.
i. In humid conditions , please must use a add‐on drain pan(commercially available) to cover the whole area of
the indoor unit.
