4. INSTALLING THE Nipper
4.1 INSTALLING THE POWER SUPPLY
Select a convenient well-ventilated location within one metre of filter equipment and mount the power
supply vertically onto a wall, or post at least as wide as the ChloroMatic Nipper power supply itself. Davey
recommends that the power supply shall not be located within 3 meters of the pool water. Plug pump and
chlorinator power supply into a suitable weatherproof power outlet/controller. Where applicable, some
model variants have a 3-pin socket on the underside of the power supply, provide pump power. The unit
must be kept away from acid and other chemical storage areas. Acid and chemical vapours will corrode the
electronics inside the unit. It must also be kept away from heat sources. Good ventilation is necessary for
correct operation.
Two self-tapping screws and wall plugs have been provided for fast and simple installation.
Use a 6mm masonry drill bit when fitting Power Supply to a brick or concrete wall. When mounting to a post
drill pilot holes and fit screws provided. Holes should be level and 164mm apart. Once screws are in position
simply hang ChloroMatic Nipper power supply via mounts on back of Unit.
