Safety Advice; Maintenance And Cleaning - Aqua Medic Helix Max Serie Manual De Instrucciones

4. Safety advice

The radiation of the UV-C lamps is dangerous. Direct contact with eyes or skin can result in irre-
versible 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 sub-
merged 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.
