Water Supply Installation; Electrical Installation - HOESCH Whirlsystem Deluxe Instrucciones De Montaje

A direct connection, via a solenoid valve, between the drinking water supply and the tub fl ushing system (nonpotable
water system) is not permissible according to DIN 1988, Part 4. To guarantee that tub contents do not fl ow back into the
drinking water supply, a backsiphonage preventer, type A2 (DN 15 or DN 20) should be installed! The backsiphonage
preventer should be installed at least 150 mm above the tub rim!
There is a factory pre-installed fl ow control
valve in the fl ushing system's cold water
feeder in order to control the rate of fl ow.
Depending on local water network pressure
conditions, a regulation and, if necessary, a
reduction should be carried out in the initial
operation so that a
maximum water height of approx.
10 mm above
the air-ground nozzle in the whirlpool
results during the system fl ush.
This setting should be checked by
a plumber.

02.03 Water supply installation

The water and drain system should be made in compliance with the binding regulations.
At installation to potable water supply, service technician or user must connect fi rst a safety device according to local
regulations.

02.04 Electrical installation

The Hoesch whirl tubs are designed for home usage (including hotels, workers' hostels, student hostels, etc.) and meet
the requirements included in relevant DIN/EN norms. An exception is using them for medical purposes.
Notice:
All electrical works should be done by the authorized electrician in accordance with the applicable
standard DIN/EN, typical country norms and the local energy law!
The whirl system is designed to operate with the alternating voltage of 230 V~AC, 50/60 Hz, 2kW. The electrical power of
the whirl system should be carried from a separate electric circuit and properly protected with a 16 A fuze, in compliance
with the rated power consumption, according to the rating plate. Other users cannot be connected. According to
standards whirlpool baths as I Class electrical devices must be permanently connected to the electrical system via
a bipolar disconnector. For security reasons, the bath supply cable must be connected to the electricity only through
electrical connector secured by overcurrent disconnector and differential current circuit breaker (RCD device) with a
nominal current of 30 mA, which will separate in all poles the installation from electrical network leaving contacts open
width of at least 3 mm. The RCD device shall be verifi ed at least once a month. It is recommended that in situations
when whirl tub is not used for a longer time the whirl installation should be switched off from the power supply system
with the use of the master switch/FI. Minimum cross section of the bath supply cable is 3x1,5 mm² (length L = 1,8 m). In
case of bathtubs equipped with an electric water heater (2 kW) a supply cable with cross section of 3x2,5mm² (length L =
2.0 m) should be used. Fixed electrical connection of the bath should be prepared in zone I (the unit is located under the
tub), compensatory connection should be provided additionally. A marked clamp
which a compensating cable 4mm² should be connected.
We recommend using the specially designed „Hoesch
backsiphonage preventer for concealed in-wall installation" (Art.
No. 6962) DVGW approved.
Install behind the long side of the tub nearest the wall
according to the illustration on page 22. Connect to the front
tub fi ttings with standard fl exible VPE tubing if possible. When
installing the backsiphonage preventer outside the tub area, a
funnel drain must be provided beneath the plastic instert. The
minimum installation height of 150 mm above the tub rim must
be observed. The conduit should not be allowed to rise behind
the back siphonage preventer.
