INSTALLATION INSTRUCTIONS CONT'D.
E.
REMOTE CONDENSERS
Remote condensers should
be
installed above the ice machine and 3n
a
level
configuration.
they
are
connected
to
the ice making unit by copper tubing
and line valves. The female
half of
the line valve ismounted on the ice
making unit and
the
remote condenser. The male half
i5
soldered on the
tube ends when tubing kits
are
provided
with
the machine.
If
tubing kits
are
not provided, the male half
of
the line valves
will
be provided in
a
valve
&it
and
the installer
will
mount them on the tubing he provides.
1.
NOTE:
STANDARD REFRIGERATION PRACTICES FOR VERTICAL LINES
TO
ASSURE POSITIVE
OIL RETURN
TO
THE CUMPKESSOR. VERTICAL LIFT TO BE NO MORE THAN
15
FEET,
WHEN VERTICAL LINES ARE INVOLVED INTHE INSTALLATION, FOLLOW',
2.
NOTE:
WE
DO
NOT RECOMMEND TUBING HUNS OF MORE THAN
40
FEET.
3.
NOTE: THE SEALS FOR THE LINE VALVES
WILL
BE FOUND INAN ENVELOPE
ON
THE REMOTE CONDENSER. MAKE SURE THEY ARE USED.
4.
NOTE: REMOVE CAP PLUGS
FROM
ALL LINE VALVES BEFORE MAKING VALVE
CONNECTIONS WITH THE SEAL.
5.
NOTE: A LOW VOLTAGE ELECTRICAL CONTROL CIRCUIT MUST BE FIELD WIRED
BEWEEN
THE
ICE MACHINE AND THE REMOTE CONDENSER RELAY. THOSE WIRES
SHOULD BE RUN WITH THE TUBING DURING INSTALLATION. REFER TO APPLICABLE
WIRING
DIAGRAMS.
6.
WHEN THE LINE VALVES ARE CONNECTED
TO
EACH OTHER THE REFRIGERANT CIRCUIT
IS
COMPLETE. EACH VALVE HALF HAS ITS OWN SHUT OFF WHICH MUST
BE
FULLY
OPENED TO ALLOW THE REFRIGERANT TO FLOW THROUGH THE SYSTEM BEFORE IT
IS STARTED.
The ice making unit utilizing
a
remote condenser
is
shipped from the factory
with the receiver holding the refrigerant charge. Additional refrigerant
may
be required upon installation depending upon the ambient conditions the remote
condenser
is
operating under, the condenser and line sizing.
A
three
way
head pressure control valve
is
used to maintain
a
relatively
consistent head pressure between
180
and
200
PSI
for
R-502
in
the
receiver in
cold
ambient conditions
to
insure
a
good harvesting or defrosting
of
the ice
slabs
on the evaporator. Because of this
valve
some
liquid refrigerant
wi
11
be held in the condenser.
NOTE:
TOTAL PRESSURE DROP
OF
14
POUNDS
OR
MORE IS WATED BETWEEN
THE
ICE MAKING
UNIT, THROUGH THE TUBING TO THE REMOTE CONDENSER, THE CONDENSER AND THE
RETURN TUBING TO THE
ICE
MAKING
UNIT.
THE
HEAD PRESSURE CONTROL
VALVE
WILL
NOT OPERATE CORRECTLY WHEN
A
The remote condenser requires
a
separate pow
supply
from
the
ice
making
unit. Refer
to
the
remote
condenser wiring diagram.
