ENGLISH
Note: 1. T h e s i z e s o f t h e i n t e r c o n n e c t i n g
pipes between the icemaker and the
compressor system should be 3/8" OD
for the liquid line and 5/8" for the suction
line up to a maximum of 20 m (assuming
a straight run). For each 90° bend, add an
equivalent 0.5 m to the overall pipe length
(e.g. 20 m straight pipe + four 90° bends =
equivalent 22 m of straight pipe).

adequately protected against low ambient
temperatures (capacity controls/crankcase
heating), oil return where the icemaker
is below the height of the compressor
(suction risers/oil traps/oil separators)
and liquid refrigerant return where the
icemaker is above the height of the
compressor (suction accumulator). Always
check the compressor manufacturer's
guidelines.
3. An electrical link/connection between the
icemaker and compressor system is NOT
necessary. Where a multi compressor
rack system is used, the icemaker 's
internal controls will close the electrically
operated solenoid valves to stop ice
p r o d u c t i o n . W h e r e a s i n g l e r e m o t e
compressor is used, this must be fitted
with a low pressure safety switch to stop
the compressor at approx. 0.5 bar suction
pressure as the solenoid valve's closing
will result in the compressor pumping
down.

2) After completing all the refrigeration tubing
connections, the pipe work should be leak
tested, evacuated and vapour charged with
R404A. The design pressure of R404A is 31.4
bar (3.08 MPa) at discharge side and 16.7 bar
(1.64 MPa) at suction side.
3) The refrigeration connections are now complete.
Proceed to sections 4 and 5 to continue with
other service connection requirements before
completing section 6, the start-up procedure.
4) Refit the side and top panels in their correct
positions.

WARNING
THIS APPLIANCE MUST BE EARTHED
This icemaker requires an earth that meets
t h e n a t i o n a l a n d l o c a l e l e c t r i c a l c o d e
requirements. To prevent possible severe
electrical shock to individuals or extensive
damage to equipment, install a proper earth
wire to the icemaker. Disconnect the main
power supply before any maintenance, repairs
or cleaning is undertaken.
* T h i s a p p l i a n c e r e q u i r e s a s e p a r a t e 2 2 0 -
240VAC, 12A supply. The electrical supply must
be protected by a suitable circuit breaker.
* Usually an electrical permit and services of a
licensed electrician are required.
* If the supply cord is damaged, it must be
replaced by a special cord or assembly available
from the manufacturer or its service agent.
For the U.K. and the Republic of Ireland only
* The wires in the mains lead are coloured in
accordance with the following code:
Green & Yellow = Earth
Blue = Neutral
Brown = Live
As the colours of the wire in the mains lead
of this appliance may not correspond with the
coloured markings identifying the terminals in
your plug, proceed as follows:
