Installation Instructions
Inspection
Upon reception, inspect the equipment and
notify both the carrier and the insurance
company, in writing, of any possible damage.
Environmental protection
Eliminate packing in accordance
with the regulations in force on
environmental conservation.
During installation and maintenance, keep
in mind that HFC-410A and oil POE are
used.
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
leading to the exterior for easy installation
and drainage (Fig. 1).
Securing the EUKC ceiling
indoor 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
completely 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 vibration.
2.- It is advisable to fit a damper at each
discharge duct bypass so as to be able
to carry out an appropriate balance of
the system.
3.- Make sure to have easy access for
cleaning 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. between
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 - 24, 36, 42 and 60 FS 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
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
control 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.
Do not connect the power supply to the
unit, nor start it up until all piping and wiring
connections 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:
- The 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, that recommended.
- 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
servicing.
Attention:
The unit is equipped
with remote control and can
start automatically. Two minutes
prior to accessing the interior,
disconnect 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.
