4.0 SITE REQUIREMENTS

WARNING

4.1 The handwash must not be positioned where it will be subjected to freezing conditions.

WATER REQUIREMENTS

4.2 The installation must be in accordance with Water Regulations. To ensure activation of the heating elements, the handwash must be connected to a mains water supply with a minimum running pressure of 0.1 MPa (1 bar) and a maximum static pressure of 0.7 MPa (7 bar).

If static pressure exceeds 0.7MPa (7 bar) fit a pressure reducing valve to avoid damaging the appliance. If in doubt, the pressure should be checked taking account of other services from the same water supply which could cause the pressure to fall below the minimum. The water supply can also be taken from a cold water storage cistern provided there is a minimum head of 10m above the appliance.

5.0 CONSIDERATIONS BEFORE FITTING

IMPORTANT - INSTALLATION TO BE DONE BY A COMPETENT

INSTALLER

5.1 The appliance must be mounted on a flat surface, which covers the full width and length of the backplate. It is important that the wall surface is flat otherwise difficulty may be encountered when fitting the cover.

5.2 Ensure that the handwash is positioned over the basin, because if the

PRD operates, water will eject from the bottom of the appliance.

5.3 The outlet of the handwash acts as a vent and MUST NOT be connected to any form of outlet flow control, or any other fitting not recommended by Heatrae Sadia.

5.4 DO NOT fit the handwash to the wall and tile up to the case. It must be fitted on to a finished flat and even wall surface. This allows removal for servicing.

5.5 The control knob is an integral part of the cover - do not attempt to remove it.

5.6 Position the appliance above the

200 mm

Main water supply

(Use rear entry when it is possible) basin so that the spray will be contained within the basin and at a convenient height for hand washing see Figure 4.

5.7 A clearance of at least 130mm above and below the appliance should be allowed for access to the cover screws.

5.8 Cable entry can be from the rear

(preferred) or from the bottom. The backplate has a cut-out position to suit size of cable. When opting for bottom entry make the cut-out to suit the cable before fitting the backplate to the wall -see Figure 5.
