Amount Of Hot Water - andrews WHiC56 Owner's Manual

The water is cold when only a
single fixture is open.
Fluctuations in hot water
temperatures.
Setting temperature cannot rise.

Amount of Hot Water

The amount of hot water at a
certain fixture is not constant.
The amount of hot water in the tub
is less/more than the set amount.
Flow meter alarm does not
sound even when filled to the set
amount.
Amount of hot water available
has decreased over time.
• The unit will not heat the water if the flow rate is less than
2.5 litre per minute.
Open the fixture more or open other fixtures so that a greater
flow passes through the unit, and the unit should begin
heating again.
• Set water temperature at 48˚C to 50˚C. This will allow you
to use a higher flow of hot water thus meeting the minimum
flow requirement of 2.5 L/min.
• Clean the inlet water filter of any debris (
• Is the maximum temperature setting appropriate? (
• When hot water is demanded at other fixtures, the amount
available may be reduced. The maximum flow available from
a 32 litre model is 32L/min., from a 28 litre model is 28 L /
min. at a 25˚C temperature rise.
• Pressure fluctuations and other plumbing conditions can
cause the temperature and pressure at a fixture to be
unstable, but it should stabilize after a short time.
• There are some types of hot water taps that discharges large
volumes of hot water at first but stabilize after time.
• To keep the temperature stable, the heater limits the
amount of water that can flow through it to a small amount
initially, but the amount increases over time.
• When hot water is used for other fixtures while filling the
tub, the tub will not fill as much.
• If there is water in the bath already, or when filling is
stopped and restarted, the bath will fill more.
• The fl ow meter alarm is set to sound when hot water
is continuously discharged for the set volume of water.
If mixing valves are used, or if cold water is mixed with hot
water at the fi xture, the bath will fi ll more than the setting
of the bath fi ll function.
• Is the inlet water filter clogged? (
