SERVICING

This should be done every year. Fill in the form at the back of this publication - you may need it

in case of warranty issues.

Service the shock arrestor by inflating to 3 bar and ensure store is inhibited with a proprietary

brand of inhibitor.

Check that the blending valve is controlling hot water temperature at (about) 50°C.

To drain the unit isolate all appliances and drain via the fitted drain cock. On sealed systems open

the relief valve to allow air into the cylinder to prevent collapse.

Please see page 10 for full servicing requirements.

WARRANTY

Warranty is for ten years on the tank against failure due to manufacturing fault, and two years

on components supplied and fitted to the heating manifold and thermal store.

Conditions apply, the unit must be serviced at regular intervals and a record of service must be

maintained. It must be in a frost free environment and must be used for Public Mains potable

water only. Private supplies are not covered. It must be installed and used correctly in accordance

with manufacturer's requirements and current best practice. Scale is not covered. (See Page 7).

Chlorine level must be lower than 200ppm.

Your statutory rights are not affected by the above.

COLD SUPPLY

A minimum of 2 bar (200 MPa) pressure through a 22mm pipe is optimum. Below this the

performance may be compromised. Test the household supply by turning on mains fed taps to

ensure satisfactory flow rates can be achieved.

Above 18 litres per minute is the recommended flow. It is the installer's and householder's

responsibility to check these before installation.

Fit a 3 bar (300MPa) control valve (not supplied) if pressures are likely to be in excess of this.

This is the maximum recommended coil pressure.

NOTE: Mains pressures usually increase from late evening to early morning.
