MECHANICAL AND HYDRAULIC INSTALLATION
During installation ensure that the mains cable is disconnected from
the power supply.
Acids are very corrosive and can harm you eyes, skin and airways.
When working with pH correctors necessary caution and preventive
measures should be taken. Always wear safety googles, gloves and
clothing.
Acid container. We strongly recommend to place the acid container outside
the filter shed. If it is not possible, ensure the adequate ventilation is
provided and place the container as far from metallic and electronic
equipment as possible and NEVER underneath the pump or other device.
pH-Basic. Install the device on the wall in an easy to access location using
the bracket provided. Before attaching the bracket to the pump, use the
bracket to mark in the wall the location of the holes you will need to make
for the screws. Choose a location close to the injection point.
Injection. Install the clamp saddle provided in the return pipe after all other
equipment (pump, filter, heater, chlorinator etc.). It should be the last
element on the return line. Install the injection one way valve on the clamp
saddle. Use Teflon tape to seal the thread. Connect the injection rigid
tubbing (opaque) to the valve.
Connect the other end of the injection tube (opaque) to the injection fitting
(right side) of the peristaltic pump.
Suction. Connect the flexible suction tube (transparent) to the injection
fitting (left side) of the peristaltic pump.
Use a length of tube long enough to reach from the acid container to the
peristaltic pump and feed the tube through the black rubber grommet in
the 'anti-fume' cap. Once the cap is on the tube, fit the suction filter to the
suction tube and place the suction line into the acid container. Screw the anti
fume cap down into position.
Probe. Install pH probe preferably after the filter. If there is a salt water
chlorinator, the probe must be installed before the cell and as far as possible
from it. Try to choose a point in the circuit that never gets empty of water,
because the probe deteriorates very quickly when dry.
ELECTRICAL INSTALATION
