TC 6. Installation and commissioning

TC 6.1
The installation and commissioning of the product must be performed by qualified and experienced personnel.
TC 6.2
Check that the support structures and anchoring devices comply with the weight and shape of the product (see chapter
Dimensions and Technical Data).
TC 6.3
Fix the unit to all points provided (see chapter Dimensions) with adequate anchors and in accordance with the total weight
(net weight of the product, weight of the refrigerant, weight of the heat exchanger, weight of any ice accumulation).
TC 6.4
The product is not designed to support additional loads.
TC 6.5
Check that the electrical supply complies with the specifications as indicated on the technical data label.
TC 6.6
Before connecting the product, verify the presence of shut-off and sectioning devices on the power supply line,
protection against electric shock, protection of equipment and anything else required by law.
TC 6.7
If speed controllers are used for the electric fan, verify their compatibility. Non-compliant devices may generate noise
and may damage the motors; the Manufacturer does not guarantee the rated performance for models equipped with
speed controllers.
TC 6.8
Check that the operating condition limits (humidity, temperatures and pressure) meet the specific requirements of
the product selection.
TC 6.9
Access to the installed unit, for any type of intervention, must be reserved to experienced personnel qualified to run the
system, according to current regulations.

TC 7. General maintenance and control

TC 7.1
Before performing any maintenance work, make sure that the power supply line of the product has been sectioned:
the electrical parts may be connected to automatic controls. All maintenance work should be performed by
qualified and experienced personnel.
11 MT TC R MC EN 04 2017
TC 7.2
The product mainly consists of a finned heat exchanger with microchannel technology, structural frame in aluminium
metal sheets and electric fans.
TC 7.3
Periodically check the fixing points of the model, electrical connections and connections to the refrigerant line.
TC 7.4
Provide for periodic cleaning of the casing and the heat exchanger using suitable detergents or possibly water and soap
with a neutral pH. Do not use harsh detergents, solvents, acidic or basic solutions containing mainly copper, chlorine
or ammonia. Avoid the use of abrasives in general. If the use of sanitising products is required, check their compatibility
with the materials. If in doubt, contact the Manufacturer, requiring the specification "how to use microchannel cores".
TC 7.5
Inspection and maintenance intervals depend on the type of plant, therefore are to be defined by experienced and
qualified personnel.
TC 7.6
For any operation on the product not described in this manual, please contact the Manufacturer.
TC 7.7
Avoid carrying out on/off settings both on the air and the refrigerant side, if the air temperature is lower than -10 °C
in order to avoid thermal shocks.
TC 7.8
The electric fans are equipped with a load-bearing protective grille to allow any replacement operations to be done
completely from the outside.

TC 8. Wiring diagrams of fans

TC 8.1
The frame of each model is equipped with a ground terminal (PE) with an identification tag. It is mandatory to
connect the ground terminal of the unit to the plant or to the external conductor of the earthing system.
TC 8.2
In models with wired electrical fans it is mandatory to connect the protection conductors of the electrical fans to the
plant or to the external conductor of the earthing system.
TC 8.3
It is mandatory to use protection systems against electric shock and protection of the equipment on the power lines
of the electrical fans. The fan assemblies are equipped with thermal contacts, normally closed, inserted in the motor
windings. Connect the thermal contacts to protect the motor from overheating.
Warning: over-temperature may not directly arise from an over-current. Please be aware that the temperature switch
closes again itself when the temperature decreases without a manual reset.
