box. Even though it is not permitted to do like this under special occasions, do not remove the packaging
box, thus to avoid loosening or falling during handling.
Confirm if the installing foundation is solid. When this unit is to be installed on the metal section of the
building, make sure that the electrical insulation must comply with applicable standards.
Ensure that the place of installation is far from the area where the inflammable or explosive
substances are stored, thus to avoid possible explosion or fire due to leakage.
1.1.2 Installation Site
Ensure the top hanging piece has strong strength to withstand the weight of the unit.
The drainage pipe has convenient flow of water.
There is no obstacle blocking the return air inlet and exhaust outlet, so as to ensure sound air
circulation.
The installation spaces required by the drawing must be ensured, so as to provide enough space for
the service and maintenance.
The installation site must be far away from heat source, leakage of inflammable gas or smoke.
The indoor unit is of ceiling mount (indoor unit is hidden inside the ceiling).
The indoor and outdoor units, the power cable and the connecting electrical lines must be at least 1
meter from any TV set or radio. This is to avoid image interference or noise of the TV set or radio. (Even if
the distance is 1 meter, noise can also exist if there is strong electric wave.)
1.1.3 Caution for Installation
Generally, the unit is installed indoor on ceiling. For ceiling mounting, ensure that the hangers on
ceiling have adequate strength to support the weight of the unit.
To meet the noise and vibration requirements, the unit shall be installed by using rubber pad (thickness
≥20mm (13/16inch)) and rubber connector.
Insert a M10 expansion bolt into the hole. Drive a nail into the bolt. Refer to the profile dimensions

Precautions for unfavorable installation:
The preparation of all pipes (connecting pipes and drainage pipes) and cables (connecting lines of
wire controller, indoor unit and outdoor unit) must be ready before the installation, so as to achieve smooth
installation.
Drill an opening on the ceiling. Maybe it is required to support the ceiling to ensure the evenness of it
and avoid the vibration of it. Consult with the user or a construction company for details.
In case the strength of ceiling is not enough, use angle iron sections to set up a beam support. Place
the unit at the beam and fix it.
Level inspection of the indoor unit
After the indoor unit is installed, it is required to check the level of the whole unit. The unit must be
placed horizontally, but the condensate pipe shall be installed obliquely, so as to facilitate the drainage of
condensate.

1.1.6 Drain Piping Work
Installation of Drainage Pipeline:
Install the drain hose in accordance with the instructions in this installation manual and keep the area warm enough to
prevent condensation. Problems with the piping may lead to water leaks.
(1) (Install the drain hose with downward gradient (1/50 to 1/100) and no risers or traps are used for
the hose (Figure 3-1-8).
(2) Be sure there is no crack or leak on the drain hose to avoid the formation of air pocket (Figure
3-1-8).
(3) When the hose is long, install supporters (Figure 3-1-9).
(4) Always use the drain hose which has been insulated properly.

(5) Use a suitable drain hose, and see Table 3-3-3 for its size.
(6) There is a drain port on both the left and right sides. Select the drain port to match the local
conditions (Figure 3-1-10).
(7) When the unit is shipped from the factory, the drain port is defaulted to be the one on the left side
(electric box side), the port on right side has been plugged.
(8) When using the drain port on the right side of the unit, reinstall the drain cap to the left side drain
port (Figure 3-1-12).

(11) There is adhesive on one side of the insulation so that after removing the protective paper over it
the insulation can be directly attached to the drain hose.
(12) Considerations for the unit with the condensate pump:
1) For the unit with the condensate pump, only one drain port at the side close to the electric box
is prepared and only through it the drain hose can be connected.
2) See table 3 for the size of the drain port of the unit with the condensate pump, which is different
from that of the unit without the condensate pump.
3) For the unit with the condensate pump, two drain ports at the bottom are defaulted to be factory
plugged with drain caps. After the installation of the drain hose, these two drain ports also need
to be insulated properly with the same way aforementioned.
4) The drain hose for the unit with the condensate pump should be arranged as shown in the
figure below.

3 REFRIGERATION PIPING WORK
3.1 Refrigeration Piping Work Procedures and Caution in Connecting
3.1.1 Flare Processing
(1) Cut the connection pipe with the pipe cutter and remove the burrs.
(2) Hold the pipe downward to prevent cuttings from entering the pipe.
(3) Remove the flare nuts at the stop valve of the outdoor unit and inside the accessory bag of the
indoor unit, then insert them to the connection pipe, after that, flare the connection pipe with a
flaring tool.
(4) Check if the flare part is spread evenly and there are no cracks (see Figure 3-3-1).

3.1.2 Bending Pipes
(1) The pipes are shaped by your hands. Be careful not to collapse them.
Extend the pipe by unwinding it
√
×
Figure 3-3-2
(2) Do not bend the pipes in an angle more than 90°.
(3) When pipes are repeatedly bent or stretched, the material will harden, making it difficult to bend or
U-Match Series DC Inverter Service Manual
81
stretch them any more. Do not bend or stretch the pipes more than three times.
(4) When bending the pipe, do not bend it as is. The pipe will be collapsed. In this case, cut the heat
insulating pipe with a sharp cutter as shown in Figure 3-3-3, and bend it after exposing the pipe.
After bending the pipe as you want, be sure to put the heat insulating pipe back on the pipe, and
secure it with tape.

Figure 3-3-3
①. To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of 150mm (5-7/8inch)
or over.
②. If the pipe is bent repeatedly at the same place, it will break.
3.1.3 Connecting the Pipe at the Indoor Unit Side
Detach the caps and plugs from the pipes.
①. Be sure to apply the pipe against the port on the indoor unit correctly. If the centering is improper, the flare nut
cannot be tightened smoothly. If the flare nut is forced to turn, the threads will be damaged.
②. Do not remove the flare nut until the connection pipe is to be connected so as to prevent dust and impurities from
coming into the pipe system.
When connecting the pipe to the unit or removing it from the unit, please do use both the spanner and
the torque wrench (Figure 3-3-4).
When connecting, smear both inside and outside of the flare nut with refrigeration oil, screw it hand
tight and then tighten it with the spanner.
Refer to Table 3-3-1 to check if the wrench has been tightened properly (too tight would mangle the nut
and lead to leakage).
Examine the connection pipe to see if it leaks, then take the treatment of heat insulation, as shown in
the Figure 3-3-4.
Use the medium-sized sponge to insulate the coupler of the gas pipe.

3.1.7 Vacuum and Gas Leakage Inspection
Do not purge the air with refrigerants but use a vacuum pump to vacuum the installation! There is no extra refrigerant in the
outdoor unit for air purging!
3.1.7.1 Vacuum
(1) Remove the caps of the liquid valve, gas valve and also the service port.
(2) Connect the hose at the low pressure side of the manifold valve assembly to the service port of
the unit’s gas valve, and meanwhile the gas and liquid valves should be kept closed in case of
refrigerant leak.
(3) Connect the hose used for evacuation to the vacuum pump.
(4) Open the switch at the lower pressure side of the manifold valve assembly and start the vacuum
pump. Meanwhile, the switch at the high pressure side of the manifold valve assembly should be
kept closed, otherwise evacuation would fail.
(5) The evacuation duration depends on the unit’s capacity, generally, 20 minutes for the 18k units,
30 minutes for the 24k/30k/36k units, 45 minutes for the 42k/48k units. And verify if the pressure
gauge at the low pressure side of the manifold valve assembly reads -1.0MPa (145psig), if not, it
indicates there is leak somewhere. Then, close the switch fully and then stop the vacuum pump.
(6) Wait for some time to see if the system pressure can remain unchanged, 3 minutes for the
18k/24k units, 10 minutes for the 30k/36k/42k/48k units. During this time, the reading of the
pressure gauge at the low pressure side can not be larger than 0.005MPa (0.72psig).
U-Match Series DC Inverter Service Manual
84
(7) Slightly open the liquid valve and let some refrigerant go to the connection pipe to balance the
pressure inside and outside of the connection pipe, so that air will not come into the connection
pipe when removing the hose. Note that the gas and liquid valve can be opened fully only after the
manifold valve assembly is removed.
(8) Place back the caps of the liquid valve, gas valve and also the service port.
