Section 1
General Information
It is recommended that this ice machine be inspected and installed by a qualified service technician.
Model Numbers
This manual covers the following models:
Self-Contained
Air-Cooled
ECV100AB
ECV100AL
Follow all recommendations and instructions for
proper installation and safe operation of this ice
machine.
WARNING
PERSONAL INJURY POTENTIAL
Do not operate equipment that has been misused,
abused, neglected, damaged, or altered/modified
from that of original manufactured specifications.
ECV model ice machines do not have a water curtain
covering the evaporator. The ice damper performs the
functions of the water curtain see Section 4 for
details.

Installation Instructions Section 2
Location of Ice Machine
The location selected for the ice machine must meet
the following criteria. If any of these criteria are not
met, select another location.
• The location must be indoors.
• The location must be free of airborne and other
contaminants.
• The air temperature must be at least 1.7°C, but
must not exceed 43.4°C.
• The location must not be near heat-generating
equipment or in direct sunlight.
• The location must be capable of supporting the
weight of the ice machine and a full bin of ice.
• The location must allow enough clearance for
water, drain and electrical connections in the rear
of the ice machine.
• The location must not obstruct airflow through or
around the ice machine (condenser airflow is in
and out the front). Refer to the chart below for
clearance requirements.
Self-Contained
Air-Cooled Self-Contained Water-Cooled
Top/Sides 203 mm* 127 mm*
Back 127 mm* 127 mm*
* NOTE: The ice machine may be built into a cabinet.
There is no minimum clearance requirement for the
top or left and right sides of the ice machine. The
listed values are recommended for efficient operation
and servicing only.
CAUTION
The ice machine must be protected if it will be
subjected to temperatures below 0°C. Failure
caused by exposure to freezing temperatures is not
covered by the warranty.
See “Removal from Service/Winterization” on page
4-11.
Ice Machine Heat of Rejection

Ice Machine Air Conditioning** Peak
ECV100 2400 3400
* B.T.U./Hour
** Because the heat of rejection varies during the ice making
cycle, the figure shown is an average.
Ice machines, like other refrigeration equipment,
reject heat through the condenser. It is helpful to
know the amount of heat rejected by the ice machine
when sizing air conditioning equipment where self-
contained air-cooled ice machines are installed.

Section 2 Installation Instructions
Leveling the Ice Machine
1. Screw the leveling legs onto the bottom of the ice
machine.
2. Screw the foot of each leg in as far as possible.
CAUTION
The legs must be screwed in tightly to prevent them
from bending.
3. Move the ice machine into its final position.
4. Level the ice machine to assure that the siphon
system functions correctly. Use a level on top of
the ice machine. Turn each foot as necessary to
level the ice machine from front to back and side
to side.

Installation Instructions Section 2
Electrical Service
GENERAL
WARNING
All wiring must conform to local, state and national
codes.
VOLTAGE
The maximum allowable voltage variation is ±10%
of the rated voltage on the ice machine model/serial
number plate at start-up (when the electrical load is
highest).
The ice machines are factory pre-wired with a 6’
power cord only, no plug is supplied.
WARNING
The ice machine must be grounded in accordance
with national and local electrical codes.
FUSE/CIRCUIT BREAKER
A separate fuse/circuit breaker must be provided for
each ice machine. An electrical disconnect switch
must be provided if the ice machine is hard wired
(wired without a plug).
TOTAL CIRCUIT AMPACITY
The total circuit ampacity is used to help select the
wire size of the electrical supply.
The wire size (or gauge) is also dependent upon
location, materials used, length of run, etc., so it
must be determined by a qualified electrician.

As the colours of the wires in the mains lead of the appliance may not correspond with
the coloured markings identifying the terminals in your plug, proceed as follows:
• The wire which is coloured green and yellow must be connected to the terminal in the
plug which is marked with the letter E or by the earth ground symbol or coloured
green or green and yellow.
• The wire coloured blue must be connected to the terminal which is marked with the
letter N or coloured black.
• The wire coloured brown must be connected to the terminal which is marked with the
letter L or coloured red.

Section 2 Installation Instructions
Water Service/Drains
WATER SUPPLY
Local water conditions may require treatment of the
water to inhibit scale formation, filter sediment,
remove chlorine, and improve taste and clarity.
WATER INLET LINES
Follow these guidelines to install water inlet lines:
• Do not connect the ice machine to a hot water
supply. Be sure all hot water restrictors installed
for other equipment are working. (Check valves
on sink faucets, dishwashers, etc.)
• If water pressure exceeds the maximum
551.5 kPA recommended pressure, obtain a
water pressure regulator.
• Install a water shut-off valve and union for both
the ice making and condenser water lines.
• Insulate water inlet lines to prevent
condensation.
DRAIN CONNECTIONS
Follow these guidelines when installing drain lines
to prevent drain water from flowing back into the
ice machine and storage bin:
• Drain lines must have a 2.5 cm drop per meter
and must not create traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Run separate bin and water-cooled condenser
drain lines. Insulate them to prevent
condensation.
• Vent the bin drain to the atmosphere.
