Installation instructions

Inspection
Upon reception, inspect the merchandise
and notify the carrier and insurance com-
pany, in writing, of any possible damage.
Environmental protection
Eliminate the packing in accordance
with the regulations on environmen-
tal conservation in force.
Contains greenhouse effect fluorided gas
covered by the Kyoto protocol
For the type of gas and quantity per system,
see the identification plate.
GWP (Global Warming Potential): 2088.
Indoor units
Location
Locate the unit, preferably, near a wall lead-
ing to the exterior for easy installation and
drainage (Fig. 1).
Securing the EUKC ceiling in-
door unit
The unit is equipped with four supports for
securing directly to the ceiling by means of
four bolts (Fig. 3) (please see corresponding
general dimensions).
Upon securing, make sure the unit is com-
pletely horizontal, or very slightly sloped
towards the drain, so as to avoid possible
drops of condensed water (use a bubble
level).
Caution
It is of great importance to be
very careful with the support of
the indoor unit with regard to the
ceiling. Make sure the ceiling is
strong enough to withstand the weight of
the unit.
Prior to hanging, check the strength of each
suspension bolt installed.
Indoor unit air ducts
1.- Connect the ducts, isolating them from
the unit by means of a flexible hose,
preferably of non-combustible material,
so as to avoid transmitting vibrations of
the unit. If the ducts are made of flexible
material, they do not transmit any vibra-
tion.
2.- It is advisable to fit a damper at each
discharge duct bypass so as to be able
10
to carry out an appropriate balance of
the system.
3.- Make sure to have easy access for clean-
ing and changing the air filters.
Drain connection (Fig. 4, 5)
It is necessary to connect a condensed
water drain pipe to the indoor unit.
Install the drain pipe through a siphon. Leave
a minimum level differential of 25 mm. be-
tween the height of the unit connection and
the line after the siphon.
Be sure to have easy access for filling the
siphon with water at the beginning of each
season.
The drain line should be sloped at least 2
cms. for each meter in length.
Drain pipe discharge can have a height
differential of 1.1 m. between the unit drain
discharge and the highest point; on models
EUKC - 26, 34, 42 & 60 FT only. Remaining
models are not equipped with a condensed
water pump.
Insulation of drain pipe
Insulate the condensed water drain pipe
so as to avoid water dripping on the floor
(Fig. 6).
Interconnection of the
units
Interconnecting the units
The cooling circuit of all Split units should
be checked for airtightness after assembly
to make sure there are no leaks.
This will help to achieve maximum services
with minimum consumption, and will avoid
serious failures of the unit. Besides, this is
also an ecological precaution.
Wiring
Electrical connections
The established national regulations
should be followed in all cases.
Each air conditioner is supplied with a con-
trol box, to which the power supply will be
connected by means of a fused main switch
or an automatic switch.
The electric heater, if applicable, should be
installed with power supply and switches
independent of the unit.
Loose cables can produce overheating at the
terminals, or incorrect operation of the unit. A
fire hazard may also exist. Therefore, make
sure all cables are connected firmly.
GB
Do not connect the power supply to the unit,
nor start it up until all piping and wiring con-
nections are completed.
Make sure the power supply is connected
correctly to the units, as shown in the wiring
diagrams.
Prior to final approval of the
installation
Make sure that:
- Voltage is always between 198-
254 V on 230 V equipment, and
342-436 V on 400 V equipment.
- The power supply cable section
is, at least, of the recommended
section.
- Condensed water drainage is
carried out correctly, and there
are no leaks in the water circuit.
- Operating instructions have been
given to the user.
- Information has been given on
the need to clean the air filter
periodically.
- The guarantee card has been
filled out.
- Maintenance instructions have
been given, or a contract has
been made for periodical servic-
ing.
Attention: The unit is equipped
with remote control and can start
automatically. Two minutes prior
to accessing the interior, discon-
nect the power supply so as to
avoid any contact with the fan
turbine in motion.
Attention: Do not touch hot
surfaces.
Attention: Possible gas leak due
to inadequate handling.
