ASSEMBLY INSTRUCTIONS
– CONNECTION
I. Appliance can be connected after unpacking
and installation in place. First unscrew and
remove the plastic cover.
II. Remove block stoppers
protecting cable
connections, both from
external module and
cables.
III. Attach and tighten cables of internal module
to connectors of stubs of external module.
NOTE!
1. Thinner (fluid) cable is to be attached to top
connection, and thicker (gas) cable to bottom
connector.
2. Use enclosed flat wrench sizes 22, 24, 27
and 30

11
3. While tightening screws always remember
holding screw with another flat wrench 22 and
27, i.e. tighten with 24 and 30 wrench and hold
with 22 and 24.
IV. Remove nuts from main valves.
Unscrew the valves completely (to the limit)
using Allen wrench.
In case of observing leaks of cooling agent,
close the valves and contact authorized service
center or retailer.

12
V. Connecting to electric installation.
Each cable is marked
with a digit
corresponding with
number on terminal
strip. Connect cables
to terminal strip
minding the numbers.
Having connected all
cables, attach
terminal strip to air-
conditioner housing.
VI. Having connected
cooling and electric
cables, replace the
cover protecting
interior against
weather conditions.

13
Properly connected external module.
Bundle excessive cable and place it behind
the modulej.
CAUTION!!!
The appliance is factor-filled with cooling agent.
Unscrewing the valves without connected cables can cause leak
of cooling agent.
Air-conditioner operation with insufficient level of cooling agent can cause damage to the appliance
TESTING THE AIR CONDITIONER
1. Connect the mains power
2. Locate the emergency power switch under the
cover of the indoor unit and turn the power on
3. The unit will sound once, the indoor fan will start
and all the lights on the unit will illuminate
4. The unit will work in AUTO mode.
After testing the unit, the emergency power switch
should only be used when the remote control is
lost or defective

ASSEMBLY INSTRUCTIONS
DISCONNECTION
I. Start air-conditioner in cooling mode. Turn off
fluid valve during appliance operation (valve
connected to thinner cable).
II. After 60 seconds turn off gas valve (valve
connected to thicker cable). Then immediately
switch off the appliance using START/STOP
button on remote control.
CAUTION!!! Compressor operation with closed
fluid valve that is longer than 60 seconds will
cause damage to appliance.
III. Turn on cooling agent valves. Always
remember to do it using two wrenches,
otherwise you may damage the valve
IV. Unscrew the cable connector.

15
Unscrew control cables from terminal strip.
V. Secure all openings with stoppers to protect
appliance against dust, sand and thread damage
CAUTION!!!
During each disassembly a minor leak of cooling agent shall occur.
The appliance is designed for 5 disassemblies. After that cooling agent is
to be refilled or replaced. Replacement or refilling shall be performed only
by specialized service center
