CRH 9
Description of appliance
This appliance is a pressure-type, hydraulically controlled instantaneous water heater for decentral
water heating at one or two taps situated in close proximity to one another. e.g. kitchen sink or
wash basin.
Due to the integrated load-shedding circuit, this appliance can be connected to the outlet box of
an electric cooker if a separate power supply is not available and provided that the cooker is con-
nected to a 3/N/PE~380/400 V supply.
Use
The instantaneous water heater heats the water as it flows through the appliance. The appliance only consumes power dur-
ing this period. The heating power is switched on automatically in the event of the minimum flow rate being exceeded. The
„Power“ light indicates that the heating system is switched on.
If the instantaneous water heater has been connected in combination with an electric cooker, the cooker will switch off while
hot water is being withdrawn. Load shedding may only be used in conjunction with electromechanical cookers! Residual
heat indicators are off while hot water is withdrawn!
The temperature of the hot water de pends on the rate of flow and the temperature of the main water supply. By opening the
tap more or less you can adjust the desired water temperature between approx. 40 °C and 60 °C:
less flow = more hot
more flow = less hot
If the heater supplies two outlets the water from the unit will be shared be tween the outlets. Therefore you should use only
one outlet at the time to have a sufficient flow and to avoid variation in temperature.
Temperature monitor
If the temperature rises too high, the temperature monitor will reduce the power supply until the
water has cooled back to the permissible level. This is indicated by the „Overheat“ light. If the
water overheats frequently, the cause of the fault must be remedied and may be due, for example,
to dirt in the filter, an excessive reduction in the rate of flow or an impermissibly high inflow tem-
perature.
Venting
To prevent damage to the appliance, the instantaneous water heater must be vented before using it for the first time. Each
time it is emptied (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the appliance
must be re-vented before it is used again.
1 Disconnect appliance from the mains by removing the fuses.
2 Next, open and close the hot water tap valve several times until no more air emerges from the pipe and all air has been
eliminated from the water heater (approx. 1 minute).
3 Only then should you re-connect the power supply to the unit.
How to save energy in order to protect the environment
The heat lost via the water pipes is very low when installed directly alongside the pipes leading to the taps (open-outlet taps
are recommended) and the hot water is rapidly supplied without drawing a great deal of cold water first.
Cleaning the filter
In case of malfunctions, the filter within the
cold water inlet
should be inspected and cleaned if necessary.
