ENGLISH
The moisture condensed on the back of the internal unit is
collected in a storage tank and removed from the room. Do
not put anything in the tank.
Attention!
Connect the internal unit first, and then the external one.
Do not let the pipelines protrude from the back of the
inner block.
Do not let the drain hose sag.
Insulate the pipes (15, 17) (fig. 11).
Make sure that the drain hose is located at the bottom
of the bundle. If you place it at the top, water can leak
inside the unit.
It is forbidden to cross and twist the power cable with
any other wires.
Lay the drain hose at an angle to drain the condensed
water.
Connect the tubes of the inner block with two wrenches
(fig. 11, 13 ). Pay special attention to the permissible
torque (tightening force), as shown in the table below,
so that the freon tubes, connectors and coupling nuts
do not deform.
First tighten them with your fingers, then use wrenches.

POWER CORD AND CONTROL CABLE
CONNECTION (fig. 12)
Inner block
Connect the power cable (19) and the control cable (20)
separately to the indoor unit terminal block (2) according
to the outdoor unit connection.
When connecting the wires to the terminal board of the
inner block, use the attached connection diagram (see
Appendix 1).
Outer block
1) Remove the indoor unit control panel access cover
(24) (fig. 12) by loosening the screw. Connect the wires
of the control cable and the power cable to terminals
on the terminal block following the connection diagram
(see. Annex 1).
2) Fasten the cables on the control panel with a cable
clamp.
3) Install the cover in its original position and secure it
with a screw.
Attention!
Make sure the power cable section corresponds to the
model specification (see the cable specification table
below).

INSTALLATION OF THE OUTER BLOCK
Install the drain port and the drain hose
Install the drain and drain hose for condensate outlet.
Condensate drips out of the outdoor unit when the unit
is in the heating mode. Not to disturb neighbors and to
protect the environment, install the drain port and the
drain hose to drain condensate. Just install the drain
port and a rubber washer on the outdoor unit chassis,
then connect the drain hose to the port (fig. 14).
Fix the chassis on a flat and solid floor with bolts and
nuts. When installing the outer block on a wall or roof,
make sure that the support is securely fixed so that it
does not shake due to strong vibration or strong wind.
Remove the caps from the 2-way and 3-way valve.
Connect the freon pipes (15, 17) separately to the 2- (29)
and 3-way (26) valves according to the required torque.
VACUUMING OF THE ROUTE
Cleaning from moisture with a vacuum pump
Air containing moisture remaining in the refrigeration
cycle may cause malfu nction of the air conditioner.
After connecting the inner and outer blocks, remove air
and moisture from the heat exchanger of the inner block
and freon tubes using a vacuum pump and a gauge
manifold (fig. 15).
Unscrew and remove the plugs (28) from the 2- and
3-way valves.
Unscrew and remove the cap from the service valve.
Connect the vacuum pump flexible hose to the service
port (27) of the 3-way valve (26). 3-way valve diagram
(fig. 16).
Turn on the vacuum pump for 10-15 minutes until abso-
lute vacuum of 10 mm Hg is reached.
While the vacuum pump is running, close the handle of
the low pressure valve on the collector of the vacuum
pump. Then turn off the vacuum pump.
After the air is pumped out, wait 5-10 minutes and use
the gauge manifold to make sure the system is tight.
FILLING THE SYSTEM WITH FREON
Use a 6-sided wrench to open the valves of the outer
block.
Open the 2-way valve for 1/4 turn, then close it after
10 seconds. Check the tightness of all joints.
Unscrew the rods of the 2- and 3-way valves complete-
ly. Disconnect the vacuum pump flexible hose.
Install and tighten all valve plugs back up.
ELECTRICAL SAFETY AND CHECKING
FOR GAS LEAKS
Checking of electrical safety
After the installation is complete, perform the electrical
safety check:
1. Insulation resistance. The insulation resistance must
be more than 2 megohms.
2. Grounding After the grounding work is completed,
measure the grounding resistance visually and with a
special tester. Make sure that the ground resistance is
below 4 ohms.
3. Checking for leakage currents (performed during a test
turn-on). During the test turn-on after the installation is
completed, a specialist can check for leakage currents
using a sensor and a multimeter. If there is a leak, the
unit should be turned off immediately. After that, you
need to find and eliminate the cause of the problem.
