machine, vibrations and effort that it can transmit. Ensuring the integrity and security of the
installation.
Do not obstruct air inlet or outlet spaces of the unit to facilitate the air intake and exhaust flow and
avoid as far as possible recirculation of air into the unit.
To ensure proper operation of the equipment and allow access for maintenance, respect the
minimum distances recommended.
Install in their location on type silentblock shock absorbers
Make sure the electric panel is in good condition before making the electrical connection, and please
follow the guidelines:
Follow the wiring diagram provided by the manufacturer.
Note that models to 400V/III/50Hz have a supply connection to 5 wires, being always the grounding
in colour green-yelow.
Install appropriate protective device on the undertaken line, thermomagnetic or thermomagnetic
differential. In cases where it is installed more than a machine it must be provided of its own system
of protection to each line.
To calculate the section of wires of the supply connection it should be considered electrical data
provided in the unit´s nameplate and other factors such as the length of the supply connection, the
type of wiring used, etc.; always respecting current regulations for electrical installations.
START-UP
Before starting/using the unit, please make sure all screws are tightened securely and the electrical
connections are properly installed. If you have worked inside the machine check that you have not left
extraneous objects or tools inside, make sure there are no gas leaks and that both assembly units and
hydraulic connections have been made properly.
Before initial startup of the gear unit or after a prolonged standstill period it is recommended to
activate the sump resistor twelve hours in advance. If the resistor cannot be enabled early enough, the
compressor must be heated otherwise to separate the oil from the refrigerant. This operation is
important, especially at low ambient temperatures start-ups.
Connect the power supply and turn on the system following the instructions given in annex of
regulation. Check subcooling and overheating to verify that the refrigerant charge is appropriate to
the operating conditions. After having been working several hours, key system parameter should be
verified to be sure that the system is working properly or it is needed to make some adjustment.
Compare temperatures of evaporation and condensation with the design conditions. Check security
features.
