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.
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 machines
Three-phase machines
Cycle frequency
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.
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.
IMPORTANT:-
The user should be made aware that on all the installations shown by figures 5, 6, 7 and
