Model C043
To the Installer
150805
Air Cooled Units
DO NOT obstruct air intake and discharge openings:
C043:
A minimum air clearance of 3” (76 mm) is
required on the left side and rear of the unit, and 0”
on the right side. The drip tray can be installed on
either side. That side requires 36” (914 mm) to allow
for installation and removal of drip tray. Allow 36”
(914 mm) at the rear of the unit for service access.
Each air cooled C043 requires three RC35 remote
condensing systems.
RC35:
Each 60 Hz remote condenser requires a
minimum air clearance of 6” (152 mm) on three
sides.
Each 50 Hz remote condenser requires a minimum
air clearance of 12” (305 mm) on three sides.
An air deflector must be installed on the condenser
side of each RC35 if the floor clearance is less than
5” (127 mm). (
Note:
The legs are typically mounted
on 4” x 4” lumber to achieve the minimum floor
clearance.)
Failure to allow adequate air clearance can reduce
the refrigeration capacity of the unit and possibly
cause permanent damage to the compressor.
Water Cooled Units
C043:
The minimum air clearance requirement is 3”
(76 mm) on both sides and at the rear of the unit.
The drip tray can be installed on either side. That
side requires 36” (914 mm) to allow for the
installation and removal of the drip tray. Allow 36”
(914 mm) at the rear of the unit for service access.
Water Connections
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan or on the right side, two 3/8” I.P.S. water
connections for inlet and outlet are provided for easy
hook-up. 1/2” inside diameter water lines should be
connected to the machine. (Flexible lines are
recommended, if local codes permit.) Depending on
local water conditions, it may be advisable to install
a water strainer to prevent foreign substances from
clogging the automatic water valve.
There will be only one water “in” and one water “out”
connection. DO NOT install a hand shut-off valve on
the water “out” line! Water should always flow in this
order: first, through the automatic water valve;
second, through the condenser; and third, through
the outlet fitting to an
open trap drain.
Minimum water pressure is 30 psi (207 kPa) and
maximum water pressure is 150 psi (1034 kPa).
A back flow prevention device is
required on the incoming water connection side.
Please refer to the applicable National, State, and
local codes for determining the proper configuration.
Electrical Connections
In the United States, this unit is intended to be
installed in accordance with the current edition of the
National Electrical Code (NEC), ANSI/NFPA 70
which governs the installation of the unit at the local
governmental level.
The purpose of the NEC code is the practical
safeguarding of persons and property from hazards
arising from the use of electricity. This code contains
provisions considered necessary for safety.
In all other areas of the world, the unit should be
installed in accordance with the existing local codes.
Please contact your local authorities.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the unit
for branch circuit overcurrent protection or fuse,
circuit ampacity, and other electrical specifications.
Refer to the wiring diagram provided inside of the
electrical box for proper power connections.
CAUTION: THIS UNIT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
