CHLORINE GENERATOR INSTALLATION
ELECTRODE HOUSING
The electrode housing may be installed either horizontally or vertically in the return water
line to the pool. The water flow through the housing may be in either direction. Plumbing
may be either 40mm or 50mm pipe.
Horizontal - the plumbing connection on the side of the electrode housing must
face downwards.
Vertical - the plumbing connection on the end of the electrode housing must
face downwards and the electrical connections must be protected from the
weather. The electrode housing should be installed in a weatherproof, well
ventilated pool shed.
Gas trap - the electrode housing must be installed to form a gas trap as shown
below. If water was to stop flowing and the chlorine generator continue running,
chlorine gas pressure will build up in the housing and pipe work and cause damages.
This can happen if water continues to run back into the electrode housing (e.g.
from a outgoing pipe after the pump is turned off), allowing water to come in
contact with the electrodes producing a build-up of gas. A gas trap allows the gas
to displace water away from the sensor terminal, thus turning off the Chlorine
generator power supply and the “water flow” alarm will sound.
