Operating Instructions
IMPORTANT WARNING:
Open the water source and allow water to run though the water heater for at least 2 to 3 minutes.
This will purge the air out of the unit and must be performed prior to turning on the power at
the unit. Failure to do so will cause serious damage to heating elements.
1. Open the water faucet for 3 minutes until the water flow is continuous and all the air has been
purged from the water pipes.
2. Turn on the circuit breaker to supply electrical power to the unit.
3. After the unit is supplied with power, a beep sound can be heard and LED lights up and stays; if
there is no other display, the appliance keeps standby.
4. Press the power button on the unit to turn ON/OFF the appliance. When the unit is working, LED
lights show Actual Temp.
5. Press + and - to adjust the outlet water temperature. The temperature setting range is 86-131°F
(30-55°C).
If the unit has been paused during use, you may initially get a short burst of very hot water
when you turn it on again. Please run the water through for a few seconds to let the
temperature settle down. Please check the hot water with your hand before taking a shower.
If the unit is not used in winter, drain out the water completely so that the heater does not
freeze. Please clean the inlet filter and the shower periodically in order to keep a proper
water flow.
Normal Maintenance

Call a technician for assistance. The power supply always needs to be shut off before these
operations are carried out.
To ensure consistent Maximum performance of the unit, it is recommended to follow these instructions:
1. Periodically remove scale and dirt that may build up at the aerator of the faucet or in the shower
head.
2. There is a built-in filter at the inlet connection which should be cleaned from time to time. Please
cut the water supply before cleaning this filter. You can then reverse the inlet and outlet pipe
connection (connect each pipe to the opposite connection) and open the faucet to manually flush
the filter by opening the faucet to its max. After flushing the filter in this way, remember to reverse
the pipes back to the normal connections.

to purge all the air out before powering on again. Failure to do so could cause serious damage to
the heating element.

frequency of your maintenance. Check the descaler device regularly to see if it is functional.

Use only a damp cloth with mild detergent to wipe away any dirt or debris.
