If the defrost electric heaters are not to be used they can be disabled by disconnecting
the neutral to the contactor coil inside the air curtain (see below and wiring diagrams on
Pages 14 & 15).
Note:
If the defrost electric heaters are disconnected, discharge air temperatures could
be very cold, approximately 6ºC. Defrost times could also be extended, particularly with
the R2-Series System. *
Do not use cable size of more than 2.5mm
2
or connection will be difficult.
See also wiring diagram on page 14 or page 15.
If the defrost electric heaters are to be disabled this can be done by disconnecting the
purple (neutral) wire from terminal A2 on the contactor inside
the air curtain. The disconnected purple wire should be
terminated safely into unused auxiliary terminal
14NO
as
shown in the adjacent picture, or into a suitable terminal block.
*NB.
Defrost does not occur with WY and WR2 systems so the
defrost cycle electric heaters should always be disconnected
on these systems.
