SOLENOID VALVE INSTALLATION
The valves must be fitted as near as possible to the tapping band
•
The valves must be screwed to a vertical surface above the top of the chemical drums and
•
no more than 750mm from the ground so that the pool pump may easily raise the chemicals
from the drums.
To meet special needs, a Venturi system can be connected to the solenoid valves.
•
SOLENOID VALVE TUBING INSTALLATION
Connect a length of tubing between the centre nipple on the solenoid valve base and the
•
tapping band injector nozzle
Connect a length of tubing to the Chlorine in-line filter and lay it neatly to the Chlorine drum
•
Connect a length of tubing to the pool Acid in-line filter and lay it neatly to the pool Acid
•
drum
Ensure that the tubing is absolutely clean and free from sand and dirt before fitting, as particles
may enter the valve and cause leakage.
Do not use any tubing other than that supplied. To do so may result in damage to the
Chemigem and negate the Warranty. If additional tubing is required for the installation of the
unit, it will be supplied at no cost.
CHEMICAL DRUMS INSTALLATION
Ensure the Chlorine and pool Acid are kept in visually different drums to avoid wrong
connection. Use colour or size differences, or both.
Refer to the cutaway diagram of chemical drum on page 12 for a presentation of the following:
Position the Chlorine and Acid drums in a safe and secure location about 2 metres from the
•
Chemigem.
Drill a 10mm hole in each of the screw-on drum caps (slightly larger than the diameter
•
of the tubing) to allow venting and to prevent the drum walls from being sucked in as the
chemicals are used.
Pass each length of supplied tubing through the hole in the appropriate drum cap.
•
Place the supplied sinkers onto the tubing and attach the appropriate drum filter.
•
When placing the tubing into the drums, measure the tubing against the outside of each
•
drum so that the drum filter will be 10-15mm above the bottom of the drum and then apply
several turns of PVC tape at a point above the cap to prevent the tubing from slipping
further into the drum.
Lower the drum filter and sinker into the drum and screw on the cap.
•
FITTING CHEMIGEM TO A HEATED POOL
If the pool heating system is controlled by a separate pool pump, there are no factors that
affect the installation of a Chemigem. If the one pool pump is required to service both the pool
heating system and the Chemigem, the pool heating plumbing must be bypassed. This will
necessitate the installation of a Venturi system at an additional cost.
