Electrical Installation

• The electrical installation must be performed by an authorized installer and follow applicable norms and regulations.
• When selecting electrical equipment, it must be selected with approved materials and enclosure class.

Pipe installation

The water heater must be supplied with:
• A safety valve
• A shut-off valve
• A drain valve
• A non-return valve
• A mixing valve
• A pressure gauge
• A vacuum valve as per applicable standards.
The water heater must be supplied with the prescribed safety equipment according to applicable local and national regulations.
The overflow pipe from the safety valve must not be able to be shut-off and must run visibly above the floor drain.

Filling

Fill the water heater as follows:
1. Open a hot water tap in the system.
2. Open the shut-off valve on the incoming cold water. This valve should then be fully open during operation.
3. The hot water tap can only be shut off when the water heater is filled, which is when only water
comes out of the tap (initially an air-water mixture comes out of the tap).
