HELPFUL HINTS AND TIPS
TP – Temperature Protection
Abnormal safety cut-out
During normal operation if the temperature
exceeds the showering safety limit (49°) the
power to the elements will be removed
completely, although water will continue to
flow. When the temperature has cooled
sufficiently, power to the elements will be
automatically restored to the settings at the
time of interruption.
Cut off the power while not in use
In normal use, it is in order to leave the water
supply permanently on to the shower unit,
but as with most electrical appliances, the
unit MUST be switched off at the isolating
switch when not in use.
It will take a few seconds for the temperature
to stabilise once changes have been made.
If restarting immediately after stopping, be
aware that a slug of hot water will be expelled
for the first few seconds.
It is advisable that the showering temperature
is satisfactory by testing with your hand
before stepping under the showerhead.
There will always be a time delay of a few
seconds between selecting a temperature and
the water reaching the setting temperature.
Setting change delay
Avoid scalding water
Test the temperature first
The temperature indicator will show a error code
when the shower is in malfunction. Below table
show what the error code mean.
This product cannot afford very high external
water pressure for safety use and usage life
reasons, highest limitation is 6-9 bar, and
PRD as product’s pressure relief device,
when external factors like handset block
happens and causes heater can not stand
the internal pressure. When reaches the highest
limit, PRD will break up to release water
pressure, and water flows out from the breaking
up point to release pressure and provide
protection.
Error code
PRD – Pressure Relief Device
The unit is fitted with a non resettable
thermal cut-out safety device. In the event of
abnormal operation which could cause
unsafe temperatures (≥ 80°) within the unit,
the device will disconnect the heatin
elements. It will require a qualified engineer to
determine the cause of the fault and handle
the repair work.
Low water pressure protection
High water pressure protection
Water flow filter
If inlet water pressure is too low, less than
0.6-0.9bar, then micro switch cannot be
connected, so heating will not start, it can
prevent heating with low water inflow, or
without any water flows in, to avoid high
temperature or heating without water.
The shower has pressure relief device, when
outlet water pressure is higher than 6-9 bar
burst pressure, rubber seal inside pressure
relief valve will burst and allow water flows
out from there to release pressure and
protect product. After pressure is released,
pressure relief valve cannot be reset, until
rubber seal need to be replaced manually.
There is a filter at water inlet, to prevent burrs
flows into water heater. The filter can stop
0.05mm impurity entering into product,
avoid block of internal water pipe and lime
scale.
