Disposal of the appliance
Old appliances must not be disposed of in your household waste!
Every consumer is legally obliged to dispose of old appliances separately from
their household waste and to take them, for example, to a collection point in
their local community or local district. Old electrical appliances will be accepted
there free of charge. This ensures that the old appliances are properly recycled
and any negative impacts on the environment are avoided. This is why electrical
appliances are marked with the symbol shown on the left.
Preparing for installation
The water and electricity supply need to be available at the place where the
device is to be supplied. If the electricity cable is buried in the wall then use the
supplied spacers. If the electricity cable is fixed to the wall then the device can
also be fixed straight to the wall.
The installation location for the appliance should keep away from the shower.
This appliance must be grounded properly!
Make sure taps/flow control device be install on the outlet of the appliance!
The appliance must be connected to a ground fault circuit interrupter.

Marey Electric Tankless Water Heater by Wahlbach
4. User Manual
Operation
The electronically regulated continuous-flow water heater with automatic tem-
perature adjustment keeps the outflow temperature constant.
The device has touch key to switch it on and off, and
/
keys to adjust the
heating.
: Decrease the outlet setting temperature;
: Increase the outlet setting temperature.
Adjust the temperature settings as desired.
If the selected outflow temperature is not reached when the tap is fully opened,
then the water flow through the device exceeds the capacity of the device. In
this case, the flow should be reduced with the hot water valve. There is a danger
of scalding at outflow temperatures exceeding 108°F.
This unit is intended for use with shower heads with a low pressure loss. Mixer
taps and thermostatic mixer taps should be of a design compatible with devices
with flow control.
Fittings for open-outlet water heaters should not be used!
Only fittings for close-outlet water heaters can be used!
Suggestion: To ensure that the minimum flow (switch-on flow) of a water-pressure
operated device is reached, the pressure loss (head loss) of the device, fittings,
shower head, shower hose and piping should all be considered when installing
the device.
Typical pressure losses at a water flow of approx. 2.6 GPM:
• Mixer tap: 5.8 - 11.6 PSI
• Thermostatic mixer tap: 4.4 - 7.3 PSI
• Shower head: 4.4 - 21.8 PSI
Without a temperature limiter, high temperatures may be reached at draw-off
points. Keep children away from the draw-off points.
Danger of scalding!
The appliance should be disconnected from the electrical mains supply when
working on the water supply. After service work is complete, proceed as during
the first-time appliance start-up.
The main water valve should be closed before any work is done on the water
pipe.
If the water supply is interrupted, e.g. due to maintenance on the mains water
supply, then the following steps should be undertaken before returning the de-
vice to operation:
1. Remove the fuses or isolate the device in another way.
2. Open a hot water valve connected to the device until the air is vented from
both the device and the cold-water supply pipe.
3. Replace the fuses or rPOWER PAKnnect the supply.
5. Maintenance
Maintenance
This device does not require any maintenance by the user. Professional mainte-
nance may only be carried out by duly authorized technical staff. Maintenance,
e.g. verifying electrical safety, should only be undertaken by a qualified electri-
cian, observing the relevant regulations (IEEE, etc.).
If faulty, please take follow the trouble shooting in page 24 to 26 to make the
diagnosis. If still have problem, never try to repair the hot water device yourself,
please contact the nearest service specialist for help.
Care
The enclosure can simply be cleaned with a damp cloth. Do not use aggressive
cleaners or cleaner’s with a scouring effect!
De-scaling
The appliance is only to be descaled by a suitably qualified specialist.
Legislation prevention
Do not use heated water as drinking water.
After prolonged shutdown of the device for example due holiday, the device
should be fully heated up to the maximum temperature (tap at minimum flow)
before re-using. It is rPOWER PAKmmended to flush the pipes for one minute.

You do not need to mix as

Problem Cause Solution
The water temperature at
the faucet is less or greater
than the temperature set-
ting of my water heater.
Anti-Scald pressure/
balancing valve or
tempering valve.
Your faucet may have an
anti-scald feature or a
tempering valve that auto-
matically mixes cold water
even when you turn your
control lever or handle to
full hot. These devices
are usually adjustable so
you can turn off the cold
mix completely. You can
compensate for this by
increasing the setting on
your water heater if you
need/want hotter water.
Thermal loss due to
long pipe run
As the hot water from the
heater runs through the
hot water delivery system
to your faucet, some heat
will be lost especially if it
has long distance to travel
or the pipes are cold.
This is normal. You can
compensate for this by
increasing the setting on
your water heater if you
need/want hotter water.
Water temperature at
the faucet is too hot
Check your flow for too
little flow, set point tem-
perature is too high.
If the appliance still fails to operate after you have executed this procedure,
please inform customer service.

Marey Electric Tankless Water Heater by Wahlbach
Troubleshooting by users
Problem Cause Solution
The water temperature at
the faucet is less or greater
than the temperature set-
ting of my water heater.
Anti-Scald pressure/
balancing valve or
tempering valve.
Your faucet may have an
anti-scald feature or a
tempering valve that auto-
matically mixes cold water
even when you turn your
control lever or handle to
full hot. These devices
are usually adjustable so
you can turn off the cold
mix completely. You can
compensate for this by
increasing the setting on
your water heater if you
need/want hotter water.
Thermal loss due to
long pipe run
As the hot water from the
heater runs through the
hot water delivery system
to your faucet, some heat
will be lost especially if it
has long distance to travel
or the pipes are cold.
This is normal. You can
compensate for this by
increasing the setting on
your water heater if you
need/want hotter water.
Water temperature at
the faucet is too hot
Check your flow for too
little flow, set point tem-
perature is too high.
If the appliance still fails to operate after you have executed this procedure,
please inform customer service.
