Electric Heating 3 Kw (Additional Equipment); Test Run; Bathtub Apron - HOESCH ERGO+ Montage- Und Bedienungsanweisung

02.02.2 Electric heating 3 kW (additional equipment)

Afters witching the electric water heater 3 kW on, the rotating water massage nozzle is switched on automatically.
The bath water temperature is maintained at the constant level of approx. 37°C.
In case of a version with integrated electric heating 3 kW the system is factory-equipped with an electric part and control
components. In such a situation a separate electric connection should be made for part of the heating power and it
should be protected separately 16 A.
Ensure polarity according to the connections diagram. Connection to the power supply system and operation of
the system only with the protection cable and connected equalizing of potentials. The power supply connection
of the system control unit and for part of the heating power should be protected with a common current trip
device 30mA.

Test run

After doing the steps indicated in point 2, you can go to the test run. You should clean the bathtub, then fill the bath with
water at 40+/- 5 ºC and start the system for 10 minutes, checking the max/min. number of rotations. Then, the whirpool
system should be turned on, and after next 10 minutes, all the pipes, wires and connection tightness should be checked.
During restarting, disinfection should be started according to instructions in 14 paragraph.

Bathtub apron

After the test run, install glass apron according to the instructions or build in the bathtub taking into consideration the
following points:
1. All systems of conduits and components of the system initially installed in the bathtub and the ones installed
at the factory must rest freely behind the walling.
The displayed system components, first of all the fan side of the pump, should be protected against dirt by
2.
covering them.
3. Mount the apron in such a way that the system components are protected against touching and water splashing.
The bathtub's operation without the apron is not allowed, except for the test run.
4. 3-4 mm width gap for silicon seal should be left between the edge of the bathtub and the apron (according to the
usage instructions by the producer)
5. In case of all models, place easily accessible and easily opening inspection windows min. 400 to 450
mm wide and 350 mm high, according to annexed drawings with dimensions.
Moreover, allow for an inspection window near the outlet.
The inspection window can be opened only with the use of proper tools. The given dimensions should be
absolutely maintained, because in case of a need for maintenance only then it is possible to easily disassemble
the system components. An ideal solution is placing the „air and inspection grate" produced by Hoesch,
dimensions 420 x 325 mm (article No. 6683.---).
6. On account of the rotating jets and the blower a free inlet of air should be provided (approx. Vo = 60,0 m³/h
with the max. number of revolutions of the blower), because when the casing is hermetically tight there
is no inlet of air to the rotating jets and to the blower. A hole with the dimensions 100 x 100 mm in the casing
is sufficient. The use of the „air and inspection grate" will provide sufficient inflow of air.
