Installation Instructions

Inspection
Upon reception, inspect the merchandise
and notify both the carrier and the insurance
company, in writing, of any possible dam-
age.
Environmental protection
Eliminate packing in accordance
with the regulations in force on en-
vironmental conservation.
During installation and mainte-
nance, keep in mind that HFC-407C
(see identification plate) POE oil are used.
Warning signs
These signs on the unit indicate potentially
dangerous conditions, and their meaning
should be remembered taken into account.

control and can start automatically. Two min-
utes prior to having access to the interior,
disconnect the power supply so as to avoid
any contact with the fan turbine in motion.

Safety
Installation and maintenance operations of
this air conditioning system should be car-
ried out by qualified and expert personnel
only. Periodical maintenance operations,
such as cleaning the coils and air filters,
should be carried out so as to keep unit
performance at an optimum.
Caution
This unit should be installed and
used in accordance with:
- Low Voltage Electrotechnical
Regulations.
- Safety Regulations for Cooling Plants and
Installations.
- Regulations on Pressure Equipment.
- Basic Construction Standards.
- Technical Construction Standards.
- Local ordinances.

Transportation
The outdoor units should always be trans-
ported in a vertical position, so as to avoid
oil leakage from the compressor. If this po-
sition has to be changed for any reason, this
should be done only for the time strictly nec-
essary.
Location
Final location should be selected previously
with permanent access for maintenance
servicing, either through the side panels or
the rear panel.
The outdoor units can be installed directly
outdoors. If installed indoors, in basements,
attics, etc., the outdoor and extraction air
intake ducts should be connected.
When installing outdoors, take into account
that in the winter operating cycle, the out-
door coil condenses a large amount of wa-
ter that should be evacuated through the
drain.
Also take into account the possibility of an
obstruction of the drain by foreign matter
such as dust or dirt.
Clearances
Clearances should be left in the installation
of each unit for:
a) Air intake and discharge of the outdoor
unit.
b) Connection of drain and electrical tub-
ing.
c) Air ducts.
d) Maintenance servicing.
e) Power supply connection.

*
-Return air without ducts (minimum clearance 600 mm)
-Retrun air with ducts (no clearance required)
Fastening the unit (on the floor)
When locating the unit on the floor, if out-
doors, it should be placed on supports so
as to avoid possible accumulation of snow,
which would obstruct air intake.

Air ducts
1 - Connect the ducts, isolating them from
the apparatus by means of a flexible
hose, preferably of non-combustible
material, so as to avoid the transmission
of vibrations from the apparatus itself. If
the ducts are made of flexible material,
they will not transmit vibrations.
2 - In the SCOC-150K, 180K and SCOH-
150K, 180K, 240K, 300K units, two in-
dependent ducts should be installed;
one for each fan up to discharge, so as
to avoid recirculation of air.
3 - If the air discharge of the outdoor coil is
carried out through ducts, it is conven-
ient that the first 1-metre section be of
galvanised sheeting so as to avoid de-
terioration due to possible dripping.
Drain connections
Install the drain tubing of each tray through
a siphon.
The drain line should be sloped a minimum
of 2 cm per meter.
Unit connections are with 28.5 outer diam-
eter copper tubing.
Attention: When the heat pump operates
at outdoor temperatures below 5°C, the
drain pipe could be obstructed due to ice.
Therefore, if installed outdoors, this possi-
bility should be taken into account, install-
ing an electric heater at the drain connec-
tion and around the compressor supports,
connecting same electrically in accordance
with the diagrams supplied.
Interconnecting the units
Unit installation comprises:
- Unit mounting.
- Refrigerant tubing connections.
- Unit wiring.
When installing split units, the cooling cir-
cuit should be completely leakproof after
mounting to insure there are no leaks.
This will help to obtain maximum perform-
ance with minimum consumption, and avoid
serious damage to the unit. This is an eco-
logical precaution as well.
Piping connection
600
The length of the interconnecting tubing of
the units should be as short as possible.
The maximum admissible distances with the
circuit and standard tubing diameter are
those indicated in each section of the cor-
responding indoor units.
Tubing to be used
Special care should be taken that the tub-
ing that interconnects the two units is kept
clean and dry, even prior to installation. It is
advisable to take into account the following
recommendations:
- Use copper refrigerant quality tubing only.
- Do not work outdoors when raining.
- The ends of the tubing should remain
closed during installation.
