Installation - Water Supply - Heatrae Sadia Aquatap Installation & User's Instructions

5.0 INSTALLATION - WATER SUPPLY

5.1 The INLET connection to the AQUATAP water heating unit is located on the top rear
of the unit (see FIG. 1, page 4). It is threaded ½" BSP male parallel flat faced
fitting. Any connection must use a suitable WRAS listed sealing washer. It is not possible
to make a compression connection directly to the INLET connection.
5.2 A WRAS listed isolating valve must be fitted in the cold water supply to the unit to
facilitate servicing the heater.
5.3 If using hard piping, ensure this is not routed where it may impair access to the case
fixing screws or prevent access and/or removal of parts for servicing or maintenance.
5.4 The use of a WRAS listed flexible braided hose assembly is recommended for the final
connection to the heater to allow for easy access/removal should it be required.
5.5 The hot OUTLET connection from the AQUATAP water heating unit is located on the top
rear of the unit (see FIG. 1, page 4). It is a hose spigot to which the flexible hot
supply hose to the dispensing tap is attached. Refer to section 8.0 INSTALLATION –
DISPENSING TAP CONNECTION, page 10 for full details of how to mount and connect
the dispensing tap to the water heating unit.
