PUTTING INTO SERVICE
b
CAUTION!
Completely fill the water circuit before
putting the product into service.
- Check that the ring nuts of all the water fittings are tight.
- Fill the system and check it for water tightness.
- Open the cold water and hot water shut-off valves
slowly in order to avoid pressure surges.
- Bleed the system as follows:
- Open a hot water tap near the product and unscrew
the thermostat knob as far as it will go.
- Open the bleed screw on the pump upstream to bleed
air from the storage cylinder side of the system. Con-
tinue until all the air has been bled from the system.
- Adjust the thermostat knob to the desired water tem-
perature.
b
All fittings are assembled in the factory. It is never-
theless advisable to check their tightness after in-
stalling the product. It is also necessary to test the
product for water tightness at operating pressure
when putting it into service.
b
Check the expansion vessel regularly in accordan-
ce with applicable standards.
- Set the pump to function at a constant pressure diffe-
rential. This ensures a constant head within the permit-
ted flow rate range.
- Fit the insulation.
- On completion of installation, check the product to en-
sure that it functions correctly and does not leak.

ELECTRICAL CONNECTIONS
The following instructions are mandatory.
1 Use a multi-pole, magnetic thermal, earth leakage breaker and disconnector that conforms to legislation in the count-
ry of installation.
2 Respect the L (Phase) - N (Neutral) polarity. Keep the ground wire about 2 cm longer than the power wires.
3 Make sure the product is correctly connected to ground.
a
It is strictly forbidden to use water pipes to ground the product.
a
Do not route the power cable near hot surfaces (like hot water pipes). Use a suitable class of cable if there is any
possibility of contact with parts at temperatures above 50°C.
b
The manufacturer declines all responsibility for damage caused by failing to ground the product adequately or by
failure to respect the wiring diagrams provided in this manual.
