Installation
WARNING This equipment must be installed by qualified persons only. Improper installation can create
electrical hazards which could result in property damage, serious injury or death. Improper installation and
servicing will void the warranty.
WARNING A qualified electrician must carry out all electrical wiring in accordance with local electrical
regulations.
For concrete pools – PU2MLP, PU2MLPW
This light is designed to be inserted into 11/2” pipe which has been cut flush and sealed at the pool wall face. It is recommended that
the receiving pipe/s be situated between 400-700mm below water level.
The receiving pipe should be extended/converted to conduit which then runs above the water level to create a run for the cable to
the central control/power point.
When the light cable is fed through the receiving pipe/conduit, sufficient cable should remain free within the pipe in order to be able
to remove the light unit to the pool surround.
Run the cable through the pipe/conduit back to the desired control/power point.
Coil the free cable into the pipe and insert the light body – the o-rings around the light will create a friction fit. The o-rings do not act as a
watertight seal. The use of a suitable lubricant on the o-rings will make the insertion of the light into the pipe easier.
Multiple lights can be installed within a single pool.
7
For vinyl liner pools – PU2MLPL, PU2MLPWL
This light is designed to be installed into a Certikin liner inlet fitting connected to either 11/2” or 2” pipe. It is recommended that the
receiving fitting/s be situated between 400-700mm below water level.
NOTICE The inlet fitting should be for use by the light only – it should not be connected to the pool
circulation system.
The liner fitting and the liner should be installed as normal. The light body is threaded and shaped in order to be a perfect fit into and
over the liner inlet clamp plate.
The pipework connected to the inlet fitting/s should be extended/converted to conduit which then runs above the water level to
create a run for the cable to the central control/power point.
When the light cable is fed through the receiving pipe/conduit, sufficient cable should remain free within the pipe in order to be able
to remove the light unit to the pool surround.
Run the cable through the pipe/conduit back to the desired control/power point.
Coil the free cable into the pipe and insert the light body – position the light body within the inlet fitting and screw the light into
place. When fully installed the light body will cover the inlet clamp plate exactly.
Multiple lights can be installed within a single pool.
