1 Visually inspect the refrigerating circuit: the presence of oil
stains can by a symptom of leakage (caused e.g. by
transportation, handling or other).
2 Verify that the refrigerating circuit is in pressure: Using the
unit manometers, if present, or service manometers.
3 Make sure that all the service outlets are closed with proper
caps; if caps are not present a leak of refrigerant can be
possible.
4 Open all of the refrigeration circuit shut-off valves (if
applicable).

1 The unit is fitted with a flow switch that is used as a safety
device and cannot be bypassed due to warranty
purposes.Carry out the following checks when starting the unit:
- circulator stopped > the flow switch contact must be open;
- circulator working > the flow switch contact must close.
If one of these two conditions does not occur, the unit
displays a water flow error.
2 Before connecting the unit to the hydraulic system, make sure
that the hydraulic system has been washed and that the
water has been drained
3 Check that the hydraulic circuit has been filled and
pressurized-
4 Check that the shut-off valves in the circuit are in the
“
OPEN
”
position.
5 Check that there is no air inside the circuit, and bleed it
through the vent valves in the high points of the system if
necessary.
6 When using antifreeze solutions, make sure the glycol
percentage is suitable for the type of use envisaged.

Neglecting the washing will lead to several filter cleaning
interventions and at worst cases can cause damages to the
exchangers and the other parts.

Check the unit is connected to the earthing system.
Check the conductors are tightened as: the vibrations caused by
handling and transport might cause these to come loose.
Power the unit by closing the isolation device but leave in OFF.
Check the network frequency and voltage values, which must be
within the limits:
220/240V +/- 10%
50 Hz +/- 1%

OTTEE
Working outside of these limits can cause irreversible damages
and voids the warranty.
