4. Safety advice
The radiation of the UV-C lamps is dangerous. Direct contact with eyes or skin can result in irreversible
damages. Therefore, the unit must always be switched off before it is opened.
The units
Helix Max 5 watts
and
Helix Max 9 watts
and
11 watts
are suitable for indoor use only.
The units may only be switched on when the water flow is on. If used on a garden pond, the units have to
be switched off and removed during winter to prevent damages from frost. The units may not be submerged
or operated under water.
5. Connection
The
Helix Max
are supplied with transparent connection pieces. This allows to control the function of the
bulbs - blue light when the UV bulbs are on.
Depending on the installed pump and water flow, the connection pieces should be cut to the best size
(metal saw).
The connections of the
Helix Max
can be rotated for 360°. This allows an easy adaptation to the mounting
conditions. In any case, the units have to be set up in a way that the outlet connection is at the highest point
to avoid air to be trapped in the unit.
6. Maintenance and cleaning
1. The UV-C lamps have a life span of approx. 8,000 hrs. After 5,000 hrs, the UV-C output of the lamps
decreases to 85%. The lamps have to be changed regularly. We recommend to clean the quartz
tube whenever the lamps are changed.
2. Switch the power off, stop the water flow and drain the water from the unit (dismount the water
connections).
3. Open the large screw cap. Careful: The lamp is fixed with the socket in the screw cap. If the screw
cap is open, you can carefully remove the lamp.
