Installing the Probe (into the Injection Manifold)
The probe supplied for use with an Injection Manifold has a bayonet fitting. To
install the probe, simply insert it into the injection manifold and twist to lock the
bayonet fitting.
Installing a Tapping Band
®
The solenoid valve model ChemiGem may be installed with a tapping band instead of an
injection manifold. This may be useful in certain applications where several pool
accessories are to be installed and space is tight.
Ensure that the suction line has no air leaks. The pump suction must be between -20kPa
and -70kPa. Turn off the pool pump before installing the tapping band.
The tapping band must be installed on the inlet (suction) side of the pump and should be
positioned as close to the pump as practicable.
The tapping band can be installed on either horizontal or vertical pipes, provided that the
probe is fitted horizontally. The tapping band has an inner shell for use with 40mm PVC
pipes. The inner shell should be removed if the tapping band is to be installed on 50mm
PVC pipes.
Drill a 19mm hole through both sides of the PVC pipe. Ensure that the surround to the
hole where the O-ring will sit is smooth and clean. Do not use grease or sealant on this
fitting. Check that the O-rings are in position and that the arrow on the tapping band is
pointing towards the pump.
Fit the tapping band and tighten the nuts by hand, with a final half turn with a wrench. Do
not over-tighten.
Installing the Probe (with tapping band)
Remove the protective cap from the probe. Retain cap for possible future use – you will
need the cap if you have to empty your pool for any reason, or if your pool is exposed to
freezing conditions.
Place an O-ring on to the probe and insert the probe into the probe arm of the tapping
band. Turn the probe clockwise by hand to tighten. Do not use grease or sealant on this
connection.
Chemical drums
Position the chemical drums in a safe and secure location, preferably about 2 metres from
®
the ChemiGem . Ensure you have the right chemicals for your pool and that chemicals
have been diluted if necessary (See page 7 for details on how to dilute chemicals).
Make sure that the correct pump/valve is connected to the correct chemical drum!
