ENGLISH
When the condensing unit operates for more than
one icemaker, install a ball valve on the liquid line
and suction line.
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. 8.

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. The sizes of the interconnecting pipes between
the icemaker and the compressor system must
be calculated based on refrigeration unit and
length of pipes.
2. When using a single compressor refrigeration
unit that is installed in a remote location,
ensure that it is adequately protected against
low ambient temperatures (capacity controls/
c r a n k c a s e h e a t i n g ) , o i l r e t u r n w h e r e t h e
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.
