Do not use the pump if the supply cable and hoses are faulty.
−
When using an extension, the power plug and socket must be waterproof.

Start-up
Connection the pump
- Cut the water supply and bleed the unit to be descaled.
- Check visually for damage on connections and hoses, change them if required (see
nomenclature)
- Connect the pump to be descaled directly to the boiler's heating unit (or exchanger). Direct
connection to the heating unit avoids damaging gaskets on the inlets and outlets of the boiler.
- Fill the pump's water tank with a quantity of water sufficient to maintain the pump casing
immersed during operation
CAUTION
Check that the level of liquid doesn't exceed 5 cm under the tank cap ; an excessive
level of liquid would damage the motor.
- Connect the power supply cable to a single phase 220V power outlet.
- Switch on the pump by pressing the switch, and check proper behaviour of the connections
- Stop the pump
.
Descaling operation
- Choose the appropriate Virax descaler and dilute it in water as indicated on the descaler
bottle.
- Start the pump
- During operation, maintain the tank cap open to evacuate any gas forming during descaling.
CAUTION
The temperature of the descaling product must never exceed 50°C.
During descaling, check that the height of the foam forming inside the tank does not
exceed the maximum filling level.
- Actuate the flow reverser several times to attack the cap in both directions.
- If the water+descaler solution loses its initial colour during the descaling operation, add
descaler immediately to the tank
