3-6 END INSTALLATION CHECKS AND START-UP
A few simple checks guarantee the correct operation
of the system:
Before switching on the condensing unit, make sure
that:
- Be adequately and firmly fixed (if mounted on
brackets, check that the rubber antivibration
mountings are well fixed between the machine and
the bracket).
- The electrical connections, including earthing, are
carried out in accordance with the national laws in
force.
- The refrigeration lines are sealed (check all
connections).
- The hydraulic system is leak-proof and leak-free.
- The supply voltage does not differ from the rated
value above ± 10%.
3-6.1 ELECTRONIC VALVE
This unit is equipped with an electronic water flow
management valve that optimizes water use.
48
The coolant valves are open.
- The water circuit taps are open.
- Check the electrical connections.
- In multisplit models, carry out the test first with only
one evaporator turned on and then the next one (in
this way any wrong connections with the ventilating
units are highlighted)
- Make sure the water is correctly drained from the
drain used and there is no back pressure.
- Check the operating gas pressure by means of a
monometric group to check the water supply
pressure.
CAUTION
In the event of an electrical blackout with
machine running, the electronic valve
will keep the position it had before the
power cut. It is recommended to check
the water flow during the blackout, and
to install a safety solenoid valve available
as an option in the event of a high
probability of power outages.
