MONOBLOC 100L
Problem
Water is too hot and/
or there is steam
To much usage of the
electric heater as a
backup (auto mode)
Low hot water flow
rate
Water discharge on
the safety group
Power consumption
is abnormally high
and constant
Electric heate not
working
Bad odour
Undraining conden-
sation
Too quick consump-
tion of the Mg anode

Possible Causes
Problem with the probe
Problem with the safety ther-
mostat
Low ambiente temperature
Low water temperature
Low voltage installation
Heat pump Error
Evaporator blocked
Fan blocked
Hydraulic circuit blocked
Absence or incorrect sizing of
expansion vessel (if leak is not
continuous)
High mains pressure (if leak is
continuous)
Leak or obstruction in refriger-
ant circuit
Dire environmental conditions
Safety thermostat ON
Defective electric heater
Absence of siphon or siphon
without water
Drainage circuit blocked
Drain pipe blocked
Over time, the magnesium anode will be consumed. This consumption is normal,
resulting of scarification to prevent corrosion of the tank. The consumption rate
differs depending on the quality of your water. Is recommended to check the
status of your anode at least every year.
Technical Manual
How to Proceed
Check error display on electronic board
Check correct running of safety thermostat
The running of the equipment depends on
weather conditions
The running of the equipment depends on the
inlet water temperature
Make sure the installation is supplied with the
indicated value for voltage
Check the error display in the electronic board
Clean the evaporator
Check the status of the fan (dust, wire...)
Check the condition of the hydraulic circuit
Installation and/or correct dimensioning of ex-
pansion vessel
Check the reducing pressure valve (if installed)
Install a reducing pressure valve (if not in-
stalled)
Check that the piping is not damaged
Use equipment suitable for checking leaks in
the circuit
Check the condition of the thermostat
Check the electric heater
Install and make sure the siphon has water
Clean the condensation circuit
Check the drain pipe
