The Pressure Switch must activate when the main pump(s) are on and de-activate when they are off (i.e. no water
flow
). It should be placed after the electrolytic cell. Placing the Pressure Switch at a bend is best:
The thread fitting of the Pressure Switch is 3mm ( 1/8”) NPT and the unit can be sealed with Teflon thread tape.
The switch should be placed so that water leaks do not interfere with the electrical switch; that is the switch should be
mounted on the side or top of a pipe/fitting, not underneath.
Please note that the voltage at the Gas Sensor is isolated Extra Low Voltage and should not pose a shock hazard.
The Pressure Switch is adjustable for static pressure. There is a l ocking tab on its back – slide it up to allow the
adjustment ring to be rotated. Rotation direction is embossed on the switch
.
ELECTRICAL CONNECTIONS
Mains Power
The Power Supply has a power cord attached to the left-hand side of its bottom panel. The Earth must be connected. The
General Purpose Outlet to which the unit is connected must be protected by a GFCI (see local electrical regulations).
If
the supply cord is damaged it must be replaced by a similar cord according to local electrical regulations.
The electrical supply to the unit must be interlocked to the main pump(s).
That is, if the main pump(s) are turned off,
so is power to the unit. This can be very important when the Powered Bypass Installation is used. The bypass pump
should also be interlocked to the main pump(s) supply.
A clean (insulated) ground must be provided to the Power Supply.
