B. WATER DRAIN

The recommended drain tube is a plastic or

flexible tube with 18 mm (3/4") I.D. which runs to

an open trapped and vented drain.

FINAL CHECK LIST

1.

Is the Cabinet level? (IMPORTANT)

2.

Have all electrical and piping connections

been made?

3.

Is there an electrical service disconnect

within sight of the installed machine?

Has the voltage been tested and checked against

the nameplate rating?

4.

Is the water supply line shutoff valve installed

near the machine.

5.

Have all the wires been checked for

looseness and thightness.

6.

Has the owner/user been instructed on

how to operate the Icemaker.

7.

Has the Manufacturer’s registration Card

been properly filled out? Check for correct Model

and serial numbers from Serial nameplate, then

mail the completed card to the FRIMONT factory.

8.

Check all refrigerant linea and conduit lines,

to guard against vibration or rubbing and possible

failure.

9.

Is there at last 20 cm. clearance behind

and around Cabinet for proper air circulation?

10. Is the Icemaker installed indoor in a location

where ambient temperatures are a Minimum of

10

°

C (50-degrees F.) all year around?

11. Has water supply pressure been checked to

insure a minimum of 1 atm (14 PSI).

12. Verify that unit lighted switch is in the OFF

position.

13. Has the owner been given name and

telephone number of the authorized SCOTSMAN

Service Agency.

3.

Ice chute to convey the ice from the outlet of

the machine to the ice storage area is supplied

with the machine.
4.

Thermostat capillary tube must be positio-

ned so that its end extends out the ice chute

opening or the ice deflector and get easily in

contact with the cone formed by the ice deposited

in the storage room, before - anyway - that ice

builds-up in the chute.

Thermostat capillary tube is coiled behind the

control box, it must be routed to follow the ice

chute or ice deflector and protrude for a certain

extension beyond the ice discharge opening in

the storage room. Use caution when routing this

capillary to prevent kink or to bent it excessively.

Coil excess capillary inside ice maker cabinet.

Tape coil to prevent vibration againt another part.

ELECTRICAL CONNECTION

See machine electrical specifications in Unit

Nameplate and at page 5 of this Service Manual

to determine wire size to be used for electrical

supply. This unit must be grounded according to

all Electrical Codes and local ordinances. Provide

a fuse disconnect box within sight and easy-

reach of the ice maker. Use timed fuses on all

terminals.

The maximum allowable voltage variations should

not exceed ten percent of the nameplate rating,

even under starting conditions. Low voltages can

cause erratic operation and may be responsible

for serious damages to the overload switch and

motor winding.

WATER SUPPLY AND DRAIN CONNECTIONS
A.

The recommended water supply line is a

3/4 inch O.D. fitting. Connect to cold water supply

line with standard plumbing fittings, with a shutoff

valve installed in an accessible place between

the water supply and the Cabinet.

In some cases, a plumbing permit and services

of a licensed plumber will be required.

CAUTION - This ice maker is equipped

with a low water pressure safety device

which, in the event of low water pressure,

will automatically stop the ice maker to

prevent damage. The ice maker will

automatically restart with increased water

pressure.

This ice maker will not operate properly

when water supply temperatures are

below 5

°

C (40

°

F) and above 35

°

C (90

°

F).

NOTE

.  

Water supply must be installed to

conform with local plumbing codes. In

some cases, a plumbing permit and

services of a licensed plumber will be

required.
