Troubleshooting
Problem
Possible Cause(s)
Solution
Leaking from
Chamber
1. O-rings Not Seated
2. Knurled Nuts too Loose
3. Damaged Thimble
1.
If there is any issue with the o-rings in the way
they are seated this will need to be fixed. Remove
the thimble and repeat steps 3 – 5
2.
If the nuts are not tight enough, the o-rings will not
have good enough compression and will cause a
leak. Slightly tighten up the nuts until a watertight
seal is achieved. It is better to tighten slightly at a
time to prevent overtightening.
3.
If there is a crack or hole in the thimble, it will fill
from the inside out. Turn off the water, carefully
remove the thimble and replace with a new one. If
the thimble releases and shards of glass, this
chamber and downstream plumbing will need to be
thoroughly checked and any glass removed before
re-connection.
High Water
Temperature
1. Low Flow Rate
2. Oversized System
1.
Particularly on the smaller model (GT7-2K) if
there are periods of low water usage or the water is
allowed to stand for long periods of time, the water
may be prone to heating up and may be either
lukewarm or hot. Generally, this only occurs on
systems that have a short distance between the
outlet and point of use. Whole house systems have
a larger length of cold plumbing pipes downstream
which will dissipate this temperature.
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 practice to install 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 (sold
separately) on the outlet of the UV chamber which
can bleed water from the chamber and keep
temperatures below 56°C
Ballast is alarming
1. Lamp Failure
1.
Usually if the ballast is alarming and showing a
red flashing status indicating light, the lamp has
failed and 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
