TotalPond MF750UV - Manual (Page 5)

To maximize the performance of the UV clarifier portion of the unit, periodically disassemble the unit to
clean dirt and debris from the exterior of the glass tube and reflector located in the lamp housing.
IMPORTANT NOTE:
Be sure that the entire unit is completely dry and gaskets are properly seated when reassembling
the UV clarifier.
Failure to do so will result in water leakage, which can cause damage to the light unit.
1. Disconnect the UV light from the outlet. Be sure to allow sufficient time for the light to cool before
disassembling the light.
2. Unscrew the locking ring, and pull out the light unit.
3. Carefully pull out the glass tube holder by twisting and then pull out.
4. Use warm, soapy water to clean the glass tube. Be sure to use biodegrable soap.
5. Reassemble the UV clarifier, and be sure that all gaskets and o-rings are seated properly.
