ELECTRICAL (MACHINE WIRING AND SUPPLY).
SEE FIGURES 5,6,7 AND 8 FOR PREFERRED METHOD
Use of the Calorex Energy Management Controller will enable greater savings to be made because the
circulating pump need only run when required and this can be at a time preferred by the customer, i.e. in the
Economy 7 period.
All electrical work to be carried out in accordance with l.E.E. standards, latest issue, or local codes of practice
as applicable.
The machine should be installed in line with EMC2004/108/EC.
Protected supply
to incorporate fuses (Type GU, FAZC) or motor (type C) circuit breakers to specified rating,
(see Data Sheet). H.R.C. fuses are recommended. An isolator 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 Calorex machines are to be guaranteed either in
performance or warranty terms:
Minimum
Maximum
Voltage
Single phase machines
207V
253V
Three-phase machines
360V
440V
Cycle frequency
47.5Hz
52.5Hz
N.B. This voltage must be available at the heat pump whilst running.
† Note the isolator must have a minimum of 3mm air gap when turned off.
IMPORTANT:-
The user should be made aware that on all the installations shown by figures 5, 6, 7 and
8 that to work on part of the intallation the supply to all parts of the installation must be
isolated.
Three phase units are fitted with a phase protection relay and will not run if phases are
connected incorrectly. A red lamp on the phase rotation relay in the electric box is
illuminated when the phases are correctly connected.
