INSTALLING THE REACTOR
The reactor chamber (
Picture 1
) is to be fixed by means of the mounting brackets, either on the
wall or on a mounting frame.
Both disinfection chamber types can be mounted vertically or horizontally; the water should flow
in from the bottom and out through the top to prevent airlocks.
Refer to
table 1b
on page 8
for the distance required from the sealing nut, in order to enable
servicing of the unit.
When mounting the chamber, consideration must be made for the weight of the system due to
the stresses associated with pipework.
PLUMBING
Connect supply from the Guardian Warm Water outlet to UV chamber inlet using a
disconnection union and isolation valve
Connect outlet of UV chamber to warm water flow line using disconnection union and isolation
valve.
WARM WATER BY-PASS
To facilitate continuing warm water supply whilst servicing the UV unit, a warm water by-pass
should be installed prior to the isolating valve at the inlet and after the isolating valve at the outlet
of the UV unit. It is recommended to remove the handle from the by-pass isolating valve and
place it in the warm water cabinet during normal operation.
INSTALLING THE POWER SUPPLY
Power supply to the UV equipment shall be in accordance with AS3000 (230 Volt +10% - 6)
.The UV system is suitable for both indoor and outdoor installation under a shelter.
The power supply box must be mounted clear of the floor as a precaution against the ingress of
water.
It is good practice to not mount the power supply unit directly under the UV reactor or water flow
pipework to avoid leakage of water onto the power supply.
The cable provided with the power supply is 1.5meters which is the maximum recommended
distance the reactor chamber should be mounted from the power supply.
Fit to wall using holes provided.
