START-UP AND OPERATION
After electric and hydraulic connections follow the indications for first operation:

Set the thermostat at its lowest temperature.

Turn on the hydraulic circuit pump and make sure there is no air left in your installation.

Switch on the differential switch, the green led should shine.

Set the thermostat to the desired temperature.

If water temperature is lower than the specified in the thermostat then after 1 minute the red light will shine and the
heater star working. When water temperature reaches the set point the heater automatically switch off until the
thermostat commands to switch on again.
MAINTENANCE
Externally the only necessary maintenance is to wipe water excess or ferruginous particles that could lead to more
extensive rusting.
If spare electric components are needed please use original spare parts as these were chosen for an optimum
performance.
RESISTANCE REPLACEMENT

Turn off the differential switch.

Disconnect supply cable from main connectors.

Extract the heater after loosening screws.

Pull out the flow switch

Disconnect resistance cables from the neutral connectors (3 cables) and the three phases from the contactor.

Get the resistances and the resistances casing.

Unscrew the resistances from its casing and replace by new ones (it is recommended to change the O-ring too).

Follow the instructions backward for assembling the heater.
ENVIRONMENT
All materials in contact witch water have been selected to work under severe conditions.

Resistance casing – AISI 316 stain-less steel.

Resistance shield – Titanium
These make them suitable for the following conditions:
