EQUIREMENTS
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).

ONNECTION
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).

Possible Cause 3.) Insufficient Flow.
Confirm this by running the system with the cartridge removed from your pump &
filter unit, this will supply the heater with the maximum flow rate your unit is capa-
ble of. If the heater then switches on (i.e. red light on) a blocked cartridge can be
confirmed to be the cause. The cartridge should be cleaned or replaced.
If using a sand filter check the pressure indicator on your sand filter and back wash
if necessary
Note;
In some cases the high limit thermostat tripping and a low flow rate can be
linked; When a filter becomes choked air can be drawn into the filtration system and
become trapped inside the heater so causing the thermostat to trip.
Possible Cause 2.) The high limiting 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 trapped inside the flow tube of the heater.

- Push the red button
