Electrical connection

The electrical supply for the installation must be provided with suitable cable and the connection has to be made in a
waterproof box. The whirlpool is delivered with a 3x2.5mm² or 5x2.5mm² cable (5x2.5mm² in case of whirlpool with two
hydromotors). The whirlpool bath must be connected with cable 3x2.5mm² 230V / 50Hz (if delivered with a 3x2.5mm²
cable). In the case of whirlpool is delivered with a 5x2.5mm² cable, it is necessary to use 2 phases. The connection must be
made with a cable 5x2.5mm² 400V / 50Hz (2 phases, 2 neutral, 1 ground) or two cables 3x2.5mm² 230V / 50Hz. Each cable
has to be protected by the appropriate circuit breaker 16A with characteristic C and earth leakage circuit breaker up to
30mA. It is necessary to ensure disconnection of all poles in the fixed supply line. The disconnecting element must have
contact distances so as to ensure that all poles are completely disconnected at Category III overvoltage (e.g. switch with
status indication). Please observe local laws and regulations regarding electrical connections. In case of doubt, consult a
plumbing specialist or contact one of the RIHO assembly or service centres.
1.5.7

Potential difference equaliser

The installation must be supplemented by a separate additional connection wire, which must be led out of the main
potential interconnection of the building or from the switchboard from which the connection for the whirlpool is taken. This
wire must have a solid core with a minimum cross-section of 4-6mm2 and its insulation must be in green-yellow
combination.
2.0 Riho acryl (PMMA) tubs (Whirlpools)
All Riho baths are made of acrylic (polymethyl methacrylic) and supported in the bottom with chipboard and reinforced
with glass fibre polyester.
Acrylic is a plastic and coloured all the way through. The properties of acrylic provide the user with the maximum
bathing comfort, provided the appropriate installation and maintenance instructions are duly followed.

Maintenance

Thanks to the non-porous, smooth surface of the material, dirt will not or will hardly stick to the material. Maintenance can
=
be limited by cleaning the bath after use with a wet sponge or cloth and a liquid cleaner (without abrasive material).
The repair of small cracks and similar damage to the bath can be performed by the user. If you want to repair minor
=
damage, due care is recommended. You may proceed as follows:
If there are fine scratches, it will be adequate to use a chrome and lacquer polisher (solvent and abrasive free). If the
=
result of this is not satisfactory, you may sand off the damage with waterproof sandpaper no. 600 and then with
waterproof sandpaper no.1000. Reprocess with a chrome and lacquer polisher for a perfect end-result and your bath
will be as good as new.
A complete set may be obtained from your dealer.

WARNING:
You may repair your bath yourself at your own risk!
Major damage, deep scratches, holes and even cracks may be repaired and can almost be made to disappear. It is
recommended that these should be repaired by specialised technicians.
