FLOW REQUIREMENTS
Your Elecro heater is factory set to accept input water flow entering on the left and
exiting on the right, this can be reversed by rotating the flow switch 180° (i.e. ½
turn) (see diagram on following page).
The heater must be installed in accordance with the country / regional requirements
& regulations. In any event the work must be carried out by a qualified electrician,
who will provide a certificate of conformity upon completion of the work. The
power supply must be fitted with a RCD.
Cable section: should be calculated at 5-amp / mm² for distances up to 20 metres
(these sections are indicative and should be checked and adapted if necessary for
cable lengths over 20 metres).

TROUBLE SHOOTING
5 = If Continuously Illuminated
Indicates that the current water temperature
has fallen below the set point temperature.
Heater will not switch from standby to on (red light)
In most cases this will be the result of one of the following not being met.
Possible Cause 1.) The set point temperature has been achieved.
To confirm that the digital thermostat is requesting the unit to heat, see if there is an
illuminated dot above the word ‘out’ on the digital thermostat (5 on diagram below).
If illuminated go to step 2, if not illuminated raise the set point temperature to a
value higher than the current water temperature. Confirm whether the heater now
switches to ‘Heat On’ mode (red light).
Possible Cause 2.) The high limit thermostat has tripped.
Remedy; remove button cover and press red button to re-set (See diagram below).
If a positive click is felt, the cause of the tripping must be investigated and could be
caused by a debris build up or air pocket forming inside the flow tube of the heater.
