GENERAL
This manual reviews general rules which must be respected during the installation and maintenance of air
conditioning systems.
Before starting the system installation read this
whole manual. Also please refer to the technical
manual and to the model being installed for more
details about its characteristics and accessories.
SAFETY PRECAUTIONS
Installation and maintenance of air conditioning equipment can be dangerous because the system is under
pressure and includes electrical components.
Only qualified and trained service technicians
should be permitted to proceed with the installation, start up and provide maintenance and
service for this equipment.
Untrained personnel can perform only basic operations
such as cleaning of air filters.
All other operations have to be made by qualified and
technically trained personnel.
During every visit follow recommendations contained
in this manual, on stickers on the unit, and take general safety precautions.
Strictly follows all safety codes. Use safety glasses and
work gloves.
Use a quenching cloth for brazing and unbrazing operations.
WARNING:
- Before starting service or maintenance, turn off the
main power switch to avoid electrical shock and injury.
- When repairing the unit, use original spare parts and
install them in the same place as the old parts.
- During the system operation, some elements of refrigeration cycle can reach temperatures above 70°C and
for this reason only qualified and trained technicians
should have access to the units components.
- Never install the units in explosive atmosphere.
EQUIPMENT RECEPTION
1. Inspect the packing. Inspect the unit. If it is damaged, or if the shipment is incomplete, immediately
file a claim with the shipping company.
2. Check that the local power supply agrees with the
specification on the unit nameplate.
INSTALLATION LOCATION
Check the following points:
1. The construction must be able to support the unit
operating weight.
2. Allow sufficient space for servicing and air flow access around the outdoor units.
3. Select a location free of dust or foreign matter which
may cause coils clogging.
4. When the outdoor unit is installed on the ground,
be sure to choose a location which cannot be flooded. It
is important to ensure at all time water evacuation
out of the unit (rain water, condensation water and
water from coil defrost in the case of heat pump system).
5. Consult and respect all regulations concerning installation of air conditioning equipment.
6. Vibration isolators pads should be provided to prevent noise transmission.
UNIT SUPPORT
Due to the size and the weight of air conditioning units
their base frame requires a support which should meet
the following conditions:
1. Support surface has to be large enough to distribute
unit weight on the building construction.
2. When the unit base has fixation holes they should
be used to keep it firmly fastened to the support.
3. The structure should support the units operational
weight.
CONDENSATE AND RAIN
WATER EVACUATION
CONDENSING UNITS: Units with centrifugal fans,
heat pump models, have a drain tube connection to
remove condensate and defrost water.
INDOOR UNITS: They have a drain pan to collect condensation water with drain tube connection.
DRAIN TUBE:
1. Use only galvanized steel, copper or plastic tube. Do
not use garden hose.
2. It is necessary to provide a flexible connection in
the drain piping to eliminate possible vibrations.
Fig. 1 - Exemple of
the trap to be
made by the installer.
5
ATTENTION: To avoid electrical shock, injury or
equipment damage, be sure that the ON-OFF power
switch is in OFF position. Field wiring must comply
with all local regulations and codes. Special attention
has to be made when making earth connections.
Supply voltage and the current has to be within 10%
of values indicated on the unit nameplate. If supply is
incorrect contact local power company.
Never operate a unit if the voltage unbalance exceeds
3%. The following formula must be used to determine
the percentage of voltage unbalance:
voltage unbalance % = largest deviation from
average voltage / average voltage.
EXAMPLE:
Nominal supply: 400.3.50
Measured voltage:
XY = 407V, YZ = 396V, ZX = 391V
Average voltage: (407+396+391)/3 =
398 V
Determine maximum deviation from average
voltage:
XY: 407-398 = 9V (= maximum deviation)
YZ: 398-396 = 2V
ZX: 398-391 = 7V
Percentage voltage unbalance: (9/398)x100 =
2.26%, <3%, therefore acceptable unbalance.
THERMOSTAT CONNECTION: Connection between the thermostat and the unit should be made
using flexible tube and to be in accordance with the
unit wiring diagram.
ATTENTION: If the unit operates at another voltage
from the specified it will loose the warranty.
ATTENTION: Compressors are mounted on
antivibration isolators. Do not remove fixing screws.
3. Provide a trap properly sized for correct water evacuation (see Fig. 1).
4. Drain piping should be located below the drain connection and should have inclination to assure proper
water flow.
AIR DUCTS
Ducts should be sized taking in consideration nominal
air flow and external static pressure of the unit.
1. Regardless of the type of the air ducts used they
cannot be flammable and cannot produce toxic gases
in the case of fire. They should have smooth inside
surface and not contaminate the air passing through
them. It is advisable to use sheet metal ducts with thermal insulation to avoid condensation on the ducts and
excessive loss of energy.
2. Connect air ducts to the unit using flexible connections so as to absorb vibrations, avoid noise transmission and make easy unit access.
3. If possible avoid installing duct elbows close to the
air outlet of the unit. If it is necessary use large radius
elbows and inside air deflectors if duct size is large
enough.
NOTE: All duct design has to be made by technicians
experienced in this matter.
ELECTRICAL
CONNECTIONS
IMPORTANT: In order to be sure that unit power supply is correct (wire entry, wires cross section, protection devices, etc..) consult electrical data table, the wiring diagram attached to the unit and check local standards concerning the installation of air conditioning
equipment.
