4. NKD1 SYSTEM INSTALLATION
4.4 ION Installation
•
Check that the O-ring is clean, greased with silicone grease (
DO NOT
use petroleum based jelly) and
securely located in the Housing.
•
Fit the ION Rods and ensure the Locking Ring is rmly tightened by hand (
DO NOT
use a tool to
tighten).
•
Connect the plug to the base of the Control Unit ensuring a rm snap lock connection.
•
Plug the Control Unit 3 pin plug into a suitable weatherproof RCD protected 10amp outlet and
then plug the pump into the 3 pin AC Socket located at the bottom of the Control Unit.
N
OTE: The pump rating must not exceed 8amps.
WARNING:
•
We
DO NOT
recommend the use of valves on the inlet or outlet of the Housing. If you do use a
valve then it is important to ensure that the valve cannot deadhead (lock closed) while the pump is
running. It is the installers responsibility to ensure some form of ow control is installed in this
instance and it disables the pump.
•
ALWAYS
ensure that pipe work and equipment do not allow gases generated to collect and build
up in any part of the installation.
• It is
RECOMMENDED
that the Housing be installed horizontally to create a natural gas trap that
acts as a safety device. Installation in any other way may cause explosion, injury or death if the
installer does not allow for gas removal. A venturi pipe is installed/moulded within the Housing
design to eliminate any possible gas build up, although it is always recommended to ensure
proper installation to eliminate this from happening.
•
The Housing must be installed in the
RETURN
pipework to the pool. It must always be installed
after the lter, gas heater, solar heating or heat pump.
•
DO NOT
apply priming uid to the Housing, it is not needed and may react with the plastic.
4.3 OXI/Housing Installation
• Connect the Housing horizontally in the return line to the pool (use reducing bushes supplied if
40mm PVC pipe) using high pressure PVC glue. The Housing can be mounted vertically but
provision must be made for a gas trap.
• Direction of water ow through the Housing is not critical although we do recommend entry from
the OXI Cell end and exit from the ION Rod end of the Housing.
• Check that the O-ring is clean, greased with silicone grease (
DO NOT
use petroleum based jelly)
and securely located in the Housing.
• Fit the OXI Cell and ensure the Locking Ring is rmly tightened by hand (
DO NOT
use a tool to
tighten).
• Connect the plug to the base of the Control Unit ensuring a rm snap lock connection.
