MAINTENANCE

SAFETY VALVE

NOTE

The anode is a consumable.

REPLACING/CHECKING THE SACRIFICIAL

ANODE

The safety valve (FL1) must be inspected regularly, about

4 times a year, to prevent clogging. The check is made by turning the safety valve's knob anticlockwise, water should then ow through the over ow pipe. If this does not happen, then the safety valve is defective and must be replaced. If there is a hot water tap in the pipe system situ below the water heater's highest point, the anode can be replaced/checked, without the water heater needing to be emptied. If there is not a hot water tap or ter heater is installed horizontally it must be drained,

The safety valve sometimes releases a little water after hot water has been used. This discharge is caused by the power to the water heater.

depending on the chemical composition of the water.

Check the anode within a year. Then check regularly, in relation to its use. When the anode is new, it has a diameter of approx. 21 mm. When this diameter has reduced, in the most consumed area, to less than 10 mm, the anode is consumed and must be replaced.

If there is no anode consumption after a few years, this could be due to poor conductivity in the water and analysis of the water is recommended.

EMPTYING

Draining is through the safety valve over ow pipe and is carried out as follows:

• Turn off the power to the water heater.
• Open the shut off valve/non-return valve by the knob (QM35) clockwise until it bottoms.

- Turn the mixer valve (FQ1) fully anticlockw

- Open the safety valve by turning the knob anticlockwise a quarter of a turn, until it is raised position.

NOTE

Water splashes may occur at the overflo

- Remove the vent screw (QM5) and open tap positioned lowest in the pipe system.

NOTE

Hot water may squirt out of the vent hole.

It can take a few minutes for draining to start work.

To speed up draining, air can be introduced screw (QM5).

Keep the valves' positions after the above actions until

the water heater is to be used again.

A small amount of water may remain at the bottom of the water heater after the draining stages described 1-5.

NOTE

The over ow pipe must be connected to pos. (XL48).

INSTALLATION

MOUNTING

The water heater must be installed in a room with ing oor drainage. The water heater can be mounted hanging vertically on a at wall (with the connections downward) or horizontally (with the rear facing down).

The heater can now slide sideways a little, which facilitates the installation of the pipes. To secure further, the closed securing bracket (UL3) is mounted on the wall against the top of the water heater as a tip guard, the gure below. An area of 200 mm free space is quired in front of/under the water heater for servicing tavork.

NOTE

For suspended installation, these spacers must be glued onto the heater to keep it parallel with

PIPE INSTALLATION

Pipe installation must be carried out in accordance current norms and directives.

The water heater is supplied with compression ring couplings for copper or plastic pipes. Internal support bushes must be fitted when a plastic or annealed pipe is used.

NOTE

Ensure that incoming water is clean. When using a private well, it may be necessary to supplement with an extra water liter.

Filling

The water heater must be lled with water before t mains supply is switched on. Filling takes place as t lows:

• Check that the vent screw (QM5) is tightened.
• Check that the safety/drainage valve (FL1) is closed
• Open the shut off valve by turning the knob (ON) on clockwise.

Setting the mixer valve

Increase/decrease the tap water temperature by turning the mixer valve knob (FQ1) anti-clockwise/clockwise.

Setting range approx. 50 - 65 °C.

ELECTRICAL INSTALLATION

NOTE

Electrical installation and service must be carried out under the supervision of a qualified electrician, and in accordance with applicable electrical safety regulations.

If the power cable is damaged it must be sealed deeper replaced by the manufacturer, its authorised service agent or another return qualified person, in order to prevent live area hazard.

The lowest point of the power cable should be belc safety power socket when you connect the water heater to the pipoet. This prevents any drops of water from being) led to the socket.

If 3 KW is required, the water heater must be connected as a permanent installation (2x400V). For permanent installation, the water heater is preceded by an isolator (preferably with a signal lamp) with at least 3 mm breaker gap. The existing power can be used if the plug is cut off.

Setting thermostat

For best operating conditions, we recommend a setting of 60 °C (max approx. 80 °C).

DEALING WITH MALFUNCTIONS

NOTE

Electrical installation and service must be carried out under the supervision of a qualified electrician, and in accordance with applicable electrical safety regulations.

If the power cable is damaged it must be replaced by the manufacturer, its authorised service agent or another service qualified person, in order to prevent service a hazard. (14 digits)

Check the installation's fuses as well as the and mixer valve settings.

Wait a few hours without hot water usage and then check whether the temperature level has risen. If there is still no hot water, contact the installation engineer.

Resetting the temperature limiter

If the temperature limiter (FD1) tripped, the water heater must cool for at least one hour before it can be reset.

• Turn off the power to the water heater
• Remove the plastic cover (QQ3).
• Press the button on the temperature limiter lightly, max 15 N (approx. 1,5 kg).
