cables.

PENETRATION OF WALL FOR TUBING

1. Mark the location of the hole on either side, according to tubing
routings, as shown. and drill it at a 5˚downward angle, as shown.

2. The hole is drilled at an angle to prevent condensed or rain water
from penetrating back into the room.

3.Trim the hole in the wall with a ø70 mm commercial plastic tube.

Fig 8

4. When installing the drain hose avoid traps and U-bends. The end of

the drain hose should not be immersed in water.

ELECTRICAL CONNECTIONS
BETWEEN INDOOR AND
OUTDOOR UNITS

1. To connect the indoor unit with the outdoor unit use the
following electrical cables, protected for outdoor use:

(see Fig. 14a)

Multiwirecable:
5 wires x 2.5 mm²
Twin wire cable:
2 wires x 0.5

SINGLE PHASE MODELS

Cooling and heating model:

mm² - For low voltage.

Multiwirecable:
4 wires x 2.5 mm².
Twin wire cable:
2 wires x 0.5 mm² - For low voltage.

(see Fig.14b)
The main power supply (5) will be connected to the outdoor
unit.

(see Fig. 14c)
The main power supply electrical cable must be of
H05VV-K5G type and contain 5 x2.5 mm² conductors,
connected to a thermally protected circuit breaker 3 x 12.5A.

2. Prepare inter-unit cable ends for connections.

3. Connect the cable ends to the terminals of the indoor and
outdoor unit, as shown in Fig. 14a, Fig. 14b and Fig. 14c.
Be sure to match the colored wires with the numbers shown
on the indoor and outdoor unit terminal boards.

4. Connect the yellow/green ground wire to the ground terminal
screw.

5. Secure multiple wire power cable with the cable clamps.

6. Fasten the twin wire cable to the power cable with cable ties.

Cooling only model:

For units above 10 KW

CONNECT THE INDOOR TO THE OUTDOOR UNIT

The indoor unit contains a small quantity of Helium. Do not unscrew the
nuts from the unit until you are ready to connect the tubing. The outdoor
unit is supplied with sufficient refrigerant charge for a 6 m tubing length.
For additional charge, please refer to outdoor unit nameplate.

To prevent crushing, bend tubes using a bending tool.
NOTE: Use refrigeration type copper tubing only.

1. Use tubing diameter that corresponds to the tubing diameter of the
indoor and outdoor units . Note that the liquid and suction tubes have
different diameters. (See tube size, torque tightening table.)

2.Place flare nuts on tube ends before preparing them with a flaring tool.
Use the flare nuts that are mounted on the supplied outdoor and indoor
units.

3. Connect the four ends of the tubing to the indoor and outdoor units.

4. Insulate each tube separately, and their unions, with at least 6 mm of
insulation. Wrap the refrigerant tubing, drain hose and electric cables
together with a vinyl tape (UV protected).

EVACUATION OF THE REFRIGERATION TUBES AND THE INDOOR
UNIT

After connecting the unions of the indoor and outdoor units, purge the
air from the tubes and indoor unit as follows:

1. Connect the charging hoses with a push pin to the low and high sides
of the charging set and the service port of the suction and liquid valves.
Be sure to connect the end of the charging hose with the push pin to the
service port.

2. Connect the center hose of the charging set to a vacuum pump.

3. Turn on the power switch of the vacuum pump and make sure that
the needle in the gauge moves from 0 MPa (0 cm Hg) to -0.1 MPa
(-76 cm Hg). Let the pump run for fifteen minutes.

4. Close the valves of both the low and high sides of the charging set
and turn off the vacuum pump. Note that the needle in the gauge should
not move after approximately five minutes.

5. Disconnect the charging hose from the vacuum pump and from the
service ports of the suction and liquid valves.

6. Tighten the service port caps of both suction and liquid valves.

7. Remove the valve caps from both valves, and open them using a
hexagonal Allen wrench.

8. Remount valve caps onto both of the valves.

9. Check for gas leaks from the four unions and from the valve caps.
Test with electronic leak detector or with a sponge immersed in soapy
water for bubbles.
