Aspirante Remote electric shower
6
WATER REQUIREMENTS
The installation must be in accordance with
Water Regulations/Bylaws. To guarantee
activation of the heating elements, the shower
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
per minute for the 8.5kW rated model and nine
litres per minute for the 9.5kW rated model.
For the 10.5kW rated shower, the minimum
running pressure must be 150kPa (1.5 bar) at a
minimum flow rate of eleven litres per minute.
For all units the maximum static pressure must
be no greater than 1 000kPa (10 bar).
If in any doubt, the pressure should be checked.
Note:
If the stated flow rate is 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 (fifteen metres
for the 10.5kW model). Minimum head is the
vertical distance from the base of the cistern
to the showerhead. It must be an independent
supply to the shower only.
If it is intended to operate the shower at
pressures above the maximum or below the
minimum stated, contact Customer Service for
advice.
