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.

It is strictly forbidden to use water pipes to ground the product.

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.

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.

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.

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.

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.
