4. General
The tankless water heater differs from conventional storage type
water heaters in several ways. It does not store hot water. Instead,
water is heated instantaneously as it fl ows through the appliance.
Due to the absence of stand-by losses, the appliance offers greater
energy effi ciency than storage type water heaters.
The MegaBoost should be installed in conjunction with a storage
tank water heater.
MegaBoost can be installed on the cold water inlet or on the hot
water outlet of the tank water heater. Installation at either location
will greatly increase the amount of hot water the tank is able to de-
liver (fi rst hour rating). Either installation location will also shorten
the recovery time necessary for the tank to recharge, but this effect
is far greater with installation on the cold water inlet.

The input of heat into the water is electronically controlled. The
appliance will deliver any water temperature between 86°F (30°C)
and 140°F (60°C). Please set the desired temperature using the knob
on the front cover.
Note:
For reasons of appliance effi ciency and durability (scaling),
the optimum temperature setting lies between 86°F (30°C)
and 120°F (50°C).
In case the “Power” light is fl ashing while the appliance operates,
the water fl ow rate exceeds the heating capacity of the appliance.
Reduce the hot water fl ow rate in order to let the appliance achieve
the set point temperature. The maximum temperature is electroni-
cally limited to 140°F (60°C). In case you have questions regarding
the way you plan to use the appliance, please call our technical
service line, see last side.

If you cannot remedy the fault, notify the contractor who installed
the appliance. To facilitate and speed up your enquiry, please pro-
vide the serial number from the type plate (000000-0000-000000).
