1) If suction pressure of the condensing unit
exceeds 0.10 MPa (1.05 bar), remove the EPR
(evaporating pressure regulator) from the suction
line. See Fig. 6.

capacity (10/10°C), set the icemaker as below.
For details, refer to the specifications on the
dimensional drawing.
Suction pressure: 0.10 MPa (1.05 bar)
Evaporating temperature: -24°C

3) While the icemaker is running, check whether
s u c t i o n p r e s s u r e o f t h e c o n d e n s i n g u n i t
and evaporating pressure of the EPR are
appropriate.
4) If the condensing unit has an inverter system,
set evaporating temperature to -25°C.
5) Piping length and height of the condensing
unit vary with installation environment and
connection method. Connect piping so that
discharge pressure of the condensing unit will
be 1.32 MPa (13.5 bar) or more. Otherwise,
pressure loss may increase and ice making
capacity may decrease.
6) Lay horizontal piping on the downgrade (1/200).
[c] LIQUID AND SUCTION LINES
1) The icemaker must be connected to the liquid
and suction lines of the compressor system using
two copper tubes of sufficient sizes directed
to the rear of the icemaker for connection to
the pre-fitted internal copper tubes. Both tubes
should be insulated separately.
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).
