General Information

Before Servicing

• Always disconnect power to any Viking product

before attempting to service it. Always verify

that power has been disconnected.

• If the unit has been running, use caution around

condenser and copper tubing. These areas may

be very hot.

• Use caution around condenser ns and

baseplate edges. These areas are sharp.

• Refrigerant is under high pressure. Always

evacuate any system before attempting to work

on it.

• Reasonable care and safe work methods should

be practiced when working on any Viking

product. Never work with energized electrical

equipment in wet or damp areas.

• Use an appropriate work area and location

when performing repairs. You will ﬁnd that it is

easier to repair undercounter units if they are

set on a raised platform or workbench.

• Always wear protective safety glasses and

gloves when working on any Viking product.

• Any refrigerant, whether CFC, HCFC, or HFC

(R-12, R-22, or R-134a), must be recovered.

Federal regulationsprohibit intentional venting

or release of refrigerants during service repair

or disposal of an appliance.

After Servicing

After servicing the unit, whether at a site or service

center, check the following:

• MAKE CERTAIN THERE ARE NO LEAKS IN

DRAIN OR WATER LINES. Check water line,

water valve, drain valve, and drain tubing for

leaks.

• Make certain ice machine functions properly

by observing ice production and ice harvest

cycles. Check for hollow ice slabs or ice slabs

that will not release.

• Make certain bin thermostat will turn unit off.

The best way to check this is to let ice maker

bin ﬁll with ice. However, if time is restricted

then use several ice cubes and place them on

bin thermostat’s capillary tube sleeve located

on side of ice bin. The unit should shut down

within a few minutes. After removing ice, unit

should start at least ﬁve minutes later.

General Information

Electrical Requirements

• 115 VAC, 60 Hz., single phase power is needed.

• Use an outlet with a 15 amp delayed action

fuse or circuit breaker. DO NOT PUT A FUSE

ON THE NEUTRAL OR GROUND OF THE

CIRCUIT.

• Properly grounded outlet is required for unit.

• It is recommended or your building code may

require that a single circuit GFCI receptacle

or breaker be used for this unit only. DO NOT

USE AN EXTENSION CORD.

• Outdoor models must use a GFCI receptacle.

Water Requirements

• Use supplied water line tting for water

connection to the rear of the unit.

• Use cold, potable water supply only with

pressure between 20 to 120 psi.

• Use 1/4 inch OD soft copper tubing. Plastic

tubing can be used, but may leak with age.

• Use 1/4 inch saddle shut-off valve. Check to

make sure valve complies with local codes.

DO NOT USE SELF PIERCING SADDLE VALVE

OR LESS THAN 1/4 INCH SADDLE VALVE AS

WATER FLOW WILL BE RESTRICTED.

• A quality system water lter or local water

ﬁlter is recommended. A quality ﬁlter can

remove particles as well as remove unpleasant

taste and odors from water.

• Softened water is not recommended

Depending on mineral concentrations, this

can produce cloudy white cubes that may

stick together.

Gravity Drain

NOTICE

A DRAIN PUMP MUST BE USED FOR ICE

MACHINE DRAIN.

The drain ﬁtting from ice maker is for 5/8 inch OD

tubing. This tubing can be routed to a gravity drain

in area shown in Figure 1 or to a remote gravity

drain that is located below ice machine. Be sure to

check your local codes. Slope any long horizontal

runs according to code to remote gravity drain for

proper drainage. An air gap may be necessary for

horizontal runs over four feet. Use thick wall tubing

that will not kink easily when icemaker is

installed. PROPER ROUTING, SLOPING, AND

SIZE OF DRAIN LINE IS IMPORTANT ESPECIALLY

IF USING FLEXIBLE TUBING OR POOR ICE

PRODUCTION WILL RESULT.

If installing a standoff gravity drain, use illustration

below for location. Standpipe can be up to three

inches high above the ﬂoor. Route tubing from ice

maker into drain pipe. See the Owner’s Guide for

additional drain information.

It may be necessary in some installations to wrap

drain tubing with wrap-type insulation to prevent

condensation on drain tube. CONDENSATION

CAN FORM ON DRAIN TUBING AND CAUSE

SURROUNDING WATER DAMAGE.

Drain Pump

A drain pump can be used to drain water when

a gravity drain is not practical. Refer to drain

pump instructions supplied with drain pump for

installation.

As with the gravity drain, it may be necessary to

wrap drain tubing from ice machine to inlet of drain

pump with wrap-type insulation. CONDENSATION

CAN FORM ON DRAIN TUBING AND CAUSE

SURROUNDING WATER DAMAGE.

WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow these instructions could result

in ﬁre or electrical shock or ﬁre.
