Installation and Service Manual
INSTALLATION
Shut off valves should be loacted in the water sup-
ply lines for ice maker and condenser (water cooled
units). The water inlet strainer must be installed in the
ice maker water supply (see diagram on water curtain
and/or rear of machine). Water supply to water cooled
condensers should include a standpipe for the preven-
tion of "water hammer".
It may be necessary to connect water supply to a
water treatment system. Consult your local Servend
Dealer or Distributor for proper size required. Water treat-
ment may pay for itself through reduced maintenance,
higher efficiency, quality of ice, and longer equipment
life.
NOTE: Water cooled units connected to recircu-
lation systems or cooling towers etc., must maintain
a minimum of 10 psi pressure drop across the con-
denser when operational.
Drains:
To ensure trouble-free drainage, vent cuber and bin
drains to the atmosphere at the cabinet (see sketch).
Drain lines from the cabinet require 1/4" (6mm) drop
per foot (30cm) fo run. Lines should terminate over an
open trapped and vented floor drain.
Electrical:
All supply wiring and connections must conform to
the national and local engineering codes. Size wiring and
fuse per nameplate specification. Connect the cuber to
a seperately fused circuit. Conduit must be connected
to the electrical control box inside the cuber, not the rear
panel on a "C" Series machine. Place a manual discon-
nect in a convenient location between the cuber and fuse
box. The cuber must be grounded by the control box
ground screw or conduit connection.
Installation Check List:
1. Has cuber evaporator been leveled?
2. Are electrical connections complete per name-
plate specifications? Is manual disconnect "ON"?
3. Check water and drain connections:
A) Has water inlet pressure been checked?
B) Are water shut-off valves open?
C) Is water strainer installed?
D) Is bin drain tube assembled to bin?
E) When used, is the water cooled condenser
drained seperately?
F) Are drain lines vented?
G) Are drain lines insulated and sloped to floor
drain?
4. Is there 6" (15.24cm) clearance at cuber sides,
back, top for air circulation?
5. Is the cuber installed where ambient tempera-
tures will not be bleow 50
o
F (10
o
C) or above 100
o
F
(38
o
C)? Will incoming water temperature be maintained
between 45
o
F (7
o
C) and 90
o
F (32
o
C)? If air temerature
drops below 50
o
F (10
o
C) shut unit down! Disconnect all
water lines to prevent freeze up of unit.
6. Does water curtain move freely?
7. Check float valve and adjust water level as re-
quired. Be certain water pan is seated on its support
block.
8. Has storage bin and cuber been sanitized?
Air deflection baffles are available for all air cooled
equipment. The baffles attach to the side and rear to
prevent air from recirculating through the condenser.
