Install The Connecting Pipe - EAS Electric VRV EVR Series Instruction Manual

3.3 Moving and installation
Since the gravity center of the unit is not at its physical center,
so please be careful when lifting it with a sling.
Never hold the inlet of the outdoor unit to prevent it from
deforming.
Do not touch the fan with hands or other objects.
Do not lean it more than 45°, and do not lay it sidelong.
Make concrete foundation according to the sepecifications of
the outdoor units.(refer to Fig.3-5)
Fasten the feet of this unit with bolts firmly to prevent it from
collapsing in case of earthquake or strong wind.
(refer to Fig.3-5)
NOTE
All the pictures in this manual are for explanation purpose only.
They may be slightly different from the air conditioner you
purchased(depend on model).The actual shape shall prevail.
3.4 Centralized Chassis Drainage
When the outdoor unit requires centralized drainage, install the
chassis and two waterproof covers for the chassis, as shown in
Figure 3-6. Install the water outlet union pipe and sealing ring on
the chassis, and then connect the drainage pipe to complete
centralized drainage installation.
Waterproof chassis cover
CAUTION
While installing the outdoor unit, pay attention to the installation
place and the drainage pattern;
if it's installed at the alpine zone, the frozen condensed water will
block up the water outlet, please pull out the rubber stopper of the
reserve water outlet. If that still fails to satisfy for the water draining,
please knock open the other two water outlets, and keep the water
can drain in time.
Pay attention to the knock the reserve water outlet from outside to
inside, and it will be beyond repair after knocking open, please pay
attention to the installation place, lest cause the inconvenience.
Please do the moth proofing for the knocked out hole, to avoid the
pest processing into and destroy the components.

4. INSTALL THE CONNECTING PIPE

Check whether the height drop between the indoor unit and
outdoor unit, the length of refrigerant pipe, and the number of
the bends meet the following requirements:
4.1 Refrigerant piping
Please pay attention to avoid the components while connect to
the connecting pipes.
To prevent the refrigerant piping from oxidizing inside when
welding, it is necessary to charge nitrogen, or oxide will chock
the circulation system.
The indoor and outdoor connecting pipe interface and power
line outlet
Vavious piping and viring patterns can be selected,such as out from
the front ,the back the side ,and undersurface, etc.(The follow display
the locations of several piping and wiring knock-off interfaces)
Table 4-1
Front out pipe
1. Side out pipe: cut the side hole of the pipe-outlet plate selectively.
It is suggested to cut a piece of metal plate below to avoid the mouse
come and destroy the machine wiring body.
2.Front out pipe: cut the frontal hole of the pipe-outlet plate selectively.
It is suggested to cut a piece of metal plate right side to avoid the
mouse come and destroy the machine wiring body.
3. Wiring of power cord: the strong and weak electrical wire should be
out through the two plastic holes of the pipe-outlet plate, and binded
with gas and liquid pipe together.
4.2 Leak Detection
Use soap water or leak detector to check every joint whether leak or
not (Refer to Fig.4-2).Note:
A is low pressure side stop valve
B is high pressure side stop valve
C and D is connecting pipes interface of indoor and outdoor units
