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.

For United Kingdom Only

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.
