2. Oversized System
short distance between the outlet and the point of
use. Whole house systems have a larger length of
cold plumbing pipes downstream.
2. If the system is too large for the application it is
likely that even with frequent water usage the water
does not get a chance to cool down effectively. If
there are significant fluctuations in usage or flow
rates, it is good practise to instal a thermal relief
valve sold separately on the outlet of the UV
chamber which can bleed water from the chamber
and keep temperatures below 56°C.
Hot SS Chamber
1. Low Usage
1. As Above, if the water is allowed to stand for
periods of time the chamber will heat up naturally.
This is normal, however if the heating is excessive to
the point where it is causing damage to the chamber
or surrounding fixtures, a thermal relief valve should
be fitted.
Ballast is alarming
1. Lamp Failure
2. Interrupted power supply
1. Usually if the ballast is alarming and showing a
red flashing status indicating light, the lamp has
failed, and it will require replacement. Before
replacing a lamp, it is best to check firstly for an
external cause for lamp failure, turn off the power
then check for water ingress from either rain, or
leaks or any signs of moisture or condensation in or
around the electricals. Due to the elevator
temperature of the lamp, high humidity may cause
condensate to form. If there are no signs of leaking,
check for signs of shorts or charring on the lamp
connection with the ballast. lastly inspect the tube to
see if there are any dark patches or if the filaments
are burnt out.
2. Sometimes the ballasts may trigger failure alarm
if the connection to the lamp is interrupted or
perhaps the connection is not solid enough. If the
above steps reveal no faults and the lamp is still
working, turn the power off for five minutes, check
connections and then turn it back on to see if the
fault clears.
No Lights on Ballast
1. Ballast failure
2. interrupted power supply
1. in the event of a large surge it is possible that the
ballast failed. This can also occur from shorts and
water ingress. cheque for signs of a short around the
lamp connexion end. The ballast will need to be
replaced. The UV lamp may also have blown at the
same time or could be the cause for the ballast
failure. for safety it is best to replace both the lamp
and ballast together. If it is within warranty. Please
contact the manufacturer for further instructions.
2. Check the wall socket with a different electrical
appliance to cheque if the GPO is functioning. Also
check your circuit breaker to see if any switches are
off.
Lamp is working but the
ballast is alarming
1. Faulty lamp
1. The lamp may be lighting up but not working at its
full capacity which may be caused by it not drawing
