Installation & User Manual
The irradiation chamber can work with a maximum operating pressure of the water of 10 bar, water hammer
can irreversibly damage the irradiation chamber or parts thereof.
7.3 Cooling of the UV system
The entire lamp power is eventually converted to heat, which means that the irradiation chamber must
always be completely filled when the UV lamps are in operation and that there must be a minimum flow to
realize sufficient cooling to prevent overheating.
Quantity of cooling water (for a temperature increase of 10 °C in the water, a flow of 100 l/h per kW is
required):
- Minimum flow with 1 x 400 W lamp = 0.04 m³/h;
- Minimum flow with 1 x 600 W lamp = 0.06 m³/h;
- Minimum flow with 2 x 600 W lamp = 0.12 m³/h.
If the UV system is included in a circulation process, it must be taken into account
that the water is heated when the UV lamp is running. If the process cannot
dissipate sufficient heat, a dangerously high water temperature can be achieved and
additional protection/cooling must be provided.
The irradiation chamber temperature is monitored by a bimetallic switch that
switches off the UV lamp at approxi60 °C outside chamber temperature.
Above a temperature of ± 42 °C damage to the skin occurs after a while. The higher
the temperature, the faster this damage will occur.
Attention!
With small water volumes, such as whirlpools or spa's, the heat from the UV lamp(s)
can heat up the water to a higher temperature than the setpoint temperature of the
concerning whirlpool or spa. In a situation such as a whirlpool, spa or other water
basin where a high temperature can cause a risk of personal injury or material
damage, the use of an additional temperature protection is obligated! The interlock
connector (E) of the control panel can be used for this.
For your safety: This product should be preferably be installed by a professional
service technician, qualified in hydrotherapy bath installation.
In case the UV system is controlled by a "Comfort" control panel and the optional Pt100 temperature sensor
is installed and connected to the irradiation chamber and the control panel and this function is activated in
the control panel, the UV lamp will be switched off standard at +45 °C outside chamber temperature.
