Current operating type (30mA) is recommended to be fitted to all pool
electrics.
INCONSISTENT ELECTRICAL SUPPLY
The following limits of operation must not be exceeded if Calorex machines are
to be guaranteed either in performance or warranty terms:
Voltage single phase
Voltage three phase
Frequency - Hz
This voltage must be made available at the heat pump while running.
† Note the Isolator must have a minimum of 3mm air gap when turned off.
NOTE: Three phase heat pumps are fitted with a phase protection relay
and will not run if the phases are not connected in the correct order
(phase sequence) or if the supply voltage is 15% less than the nominal
voltage (415V for 3N~ 50Hz). The lamp on the phase rotation relay
(situated in the electric box is illuminated when the phases are correctly
connected and the voltage is sufficient.
