Cat. No. 01021716
The following is a list of different problems that may be found while installing and operating the Executive Cooler.
NOTE Fault finding must only be carried out by trained personnel.
Symptom
Possible Cause
Solution
NO FLOW OF WATER
In this case, make sure that there is a water supply
to the unit and that it is turned on. If an anti-flood or
leak detection device is installed, please check and
reset if necessary. For units with EZ heads, ensure
that the filter is twisted all the way into the head;
otherwise the valve inside the filter head will not be
opened. Check to see that the filter is not blocked
with sediment
THERE IS FLOW FOR
THE HOT WATER, BUT
NO FLOW FOR THE
COLD WATER
This may be a result of the water in-
side the cold tank mechanism being
frozen.
Verify that the thermostat is set at the factory set-
ting. Disconnect the power mains from the back of
the machine and allow the ice inside the cold tank
to melt.
WATER DISPENSED BY
THE UNIT IS NEITHER
HOT NOR COLD
Make sure that the red heater/compressor switch at
the back of the unit is turned on.
THE POWER INDICA-
TOR IS NOT ON
Make sure that the unit is plugged in correctly and
that the red switch is on. If the unit is properly set
up, then remove the top cover of the machine and
check the fuse on the back of the unit.
BAD TASTE
Flush the unit for a period of 15 minutes. If the bad
taste persists taste the water coming directly from
the filter, if still bad change the filter, or contact your
authorized service provider.
LOW FLOW OF COLD
WATER
If this happens in the cold water cir-
cuit, there may be a problem with
freezing.
Please refer to “There is flow for the hot water, but
no flow for the cold water”.
LOW FLOW OF WATER
FOR ALL CIRCUITS OF
THE UNIT
The filter may require changing, or
there is low water supply pressure.
Ensure that the filter is not blocked.
LOW FLOW OF HOT
WATER
Indicates that the hot tank needs to
be de-scaled.
HOT WATER IS COLD
If all the electrical connections are
fitted properly, there is a chance that
the overload mechanism has been
triggered.
In this case, unplug the unit, remove the upper and
lower front panels to gain access to the hot water
tank. On the side of the hot tank there is a manual
reset button for the overload mechanism. Press the
button and reassemble all the panels. Plug in the
unit and make sure it continues to heat up the water
as normal.
COLD WATER IS WARM
Make sure that you are not testing the ambient op-
tion. Check the thermostat is at the set point. Make
sure the unit is not in direct sunlight or a room with
a high ambient temperature (32ºC +). Ensure the
heater/compressor switch is on. If none of the prior
are the source of the issue, then assume standard
refrigeration fault finding procedures.
UV FAILURE
Unplug the unit. Make sure the lamp is connected
correctly. Remove and visibly check. Is the UV start-
er operating? If the lamp and starter are OK check
UV ballast.
