WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations and Bylaws.
To guarantee activation of the heating elements,
the unit must be connected to a mains water
supply with a minimum running pressure of
100kPa (1.0 bar) at a minimum flow rate of
eight litres/minute and a maximum static
pressure of 1 000kPa (10 bar).
Note: If the stated flow rates are not available,
it may not be possible to achieve optimum
performance from the unit throughout the year.
The water supply can be taken from a cold
water storage cistern provided there is a
minimum head of ten metres above the unit.
It must be an independent supply to the
handwash unit only.
If it is intended to operate the unit at pressures
above the maximum or below the minimum
stated, contact Customer Service for advice.
Fig.4 shows a typical system layout for the 7kW
rated handwash unit.
DO NOT use jointing compounds on any pipe
fittings for the installation.
