GENERAL INFORMATION & INSTALLATION

5.

Remove all internal support packing, tape

and wires in machinery compartment.

6.

Check that refrigerant lines do not rub or

touch lines or other surfaces, and that fan blades,

if any, move freely.

7.

Use clean damp cloth or disposable paper

wiper to pipe clean the exterior surfaces of the

cabinets.

8.

See DATAPLATE on the cabinet base and

check that the location source voltage cor-

responds with the voltage specified on the

dateplate.

CAUTION

Unproper voltage supplied to

the ice Maker will void your parts

replacement program.

9.

Remove the Manufacturer’s Registration

Card from the User Manual and fill in all spaces

including: Model Number and Serial Number

taken from the aluminium plate.

Forward the completed, self addressed,

registration card to the Frimont Factory.

LOCATION AND LEVELLING

WARNING. This unit must be installed in

an area where it will not freeze and

protected from the elements such as wind,

rain, water spray or drip. Ambient tempe-

rature limitations are: 10

°

C (50

°

F)

minimum and 40

°

C (100

°

F) maximum,

while water temperature limitation are:

5

°

C (40

°

F) minimum and 35

°

C (90

°

F)

maximum. Ambient and water tempera-

ture exceeding these limitations may

result in machine malfunction and the

loss of warranty coverage.

Make sure that the structure on which the ice

maker will be located be on a solid footing and

supports at least 700 Kgs.

This ice maker is designed for free standing

application only. Do not built it in. Make sure that

location site is well ventilated to ensure correct

operation. Also allow 20 cm clearence in back

and both side of the ice maker to be able to easily

perform service inspections and operations.
1.

Erection - For elevation of machine to its

stand or location, fork lifttrucks should be used.
2.

Position the MF/MFN 88 in the selected

permanent location and level the cabinet on both

the left-to right anf front-to-rear direction.

INTRODUCTION

This manual provides the specifications and the

step-by-step procedures for the installation, start-

up, operation and maintenance and cleaning of

the SCOTSMAN Model MF/MFN 88.

The Model MF/MFN 88 is a quality designed,

engineered, constructed and throughly tested

icemaking system, providing the utmost in

flexibility to fit the needs of a particular user.

DESCRIPTION

The Scotsman MF/MFN 88 - continuous flow ice

maker - consists of one large capacity flake ice

making system contained within a compact

cabinet entirely in stainless steel. The flake ice

produced is extruded through an ice discharge

opening. All panels are removable to allow easy

access to electrical and mechanical components

for cleaning and maintenance.

SEALED REFRIGERANT SYSTEM

The freezer auger is driven by a gear motor assy.

The refrigerant used is R 404 A controlled by an

automatic expansion valve.

STORAGE BIN OR ICE ROOM

Since the MF/MFN 88 is a continuous flow type

ice maker and does not have its own attached

storage bin, it is necessary to use an auxiliary bin

or prefabricated ice room for appropriate ice

storage. An insulated ice storage bin or room is

always required, then - according to ice

applications - this can be refrigerated or non-

refrigerated; a weight/volume ratio of 1,8 m

3

 per

ton must be taken into consideration for correct

ice storage room design which, in any case,

should be dimensioned to accomodate a

minimum of 16 hrs. ice production.

UNPACKING AND INSPECTION

1.

Call your authorized SCOTSMAN

Distributor or Dealer, for proper installation.
2.

Visually inspect the exterior of the shipping

container and skid and any severe damage

noted, should be reported to the delivering carrier;

and, a concealed damage claim filled in subjetct

to internal inspection, with carrier representative

present.
3.

Remove the packing, and the shipping base

or skid.
4.

Remove screws and shipping tape, and

service panels from the cabinet, and inspect for

any concealed damage.

Notify carrier of any concealed damage claims,

as stated in step 2 above.
