Protected supply to incorporate fuses or motor type circuit breakers (Type C)
to specified rating, (see Data Sheet). H.R.C. fuses are recommended. An isolator
which disconnects all poles must be fitted within 2m and in sight of machine.†
All units must be correctly earthed-grounded. An earth leakage trip of the
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 Dantherm Ltd.
machines are to be guaranteed either in performance or warranty terms:
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: The 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.
IMPORTANT
The user should be made aware that THE WHOLE installation should be
isolated when working on ANY PART.
