This publication is the property of the Polar Krush Group and should

not be reproduced without written permission.

This booklet contains operational instructions for Polar Krush, Devil’s Ice

and Refresh machines. For the purpose of this booklet the machine

images throughout are that of the Polar Krush Classic Twin Machine,

however the usage instructions are applicable to all Refurbished and

Classic machines, which are operated in the same way.

Regular cleaning and maintenance of the machine is the responsibility

of the operating site. For hygiene purposes, we recommend that you

carry out your cleaning schedule and check your filter at least

fortnightly.

Setting up your Machine

3. You will need to ensure that there

is a clearance of 20cm at the back

and both sides of the machine. This

will ensure that the machine has

enough room for ventilation. If the

machine overheats, it won’t

function effectively.

4. Take the drip trays out of the clear

bowls, and position at the bottom of

the front panel. Make sure that the

clear overflow pipe is tucked into

the back of the tray.

5. Remove the taps from the bowls

and lubricate the shafts with

lubricant. Then simply push them into

place in the tap tubes until you hear a

click.

1. Position your machine where you will be using it. Your machine

will need to have a 240 volt electric power supply.

2. Plug the machine into the mains.

Preparing the Product

1. Pour the concentrate into a

clean product bottle and fill to the

top of the concentrate line.

2. Fill the bottle up to the neck

using the coldest water possible,

as the colder the water, the less

time it will take for your machine

to freeze down.

For best results, we recommend

that you chill your mixed product

overnight in a refrigerator.

3. Shake the bottle well and pour

the mixture into the machine. This

will give you slightly more than 5

litres of slush, as the mixture

expands slightly as it freezes.

Each bowl has the capacity for 12

litres and should be kept filled

between the minimum and

maximum levels indicated.

Your machine is now ready to start

freezing.

Freezing and Adjustment

The first time you start up your machine, it will freeze down

within two and a half hours. However when you freeze it down

each day afterwards, it will take less time.

Because these machines are refurbished, and the compressors

may have been replaced, there may be some variation in freezing

time between the two sides. This means that one side may freeze

relatively quickly, and the other side may take slightly longer. This

is quite normal, and does not mean that your machine is broken.

1. When your machine is first

switched on, it will need to chill

completely before it begins to

freeze. The liquid will remain

transparent while this is

happening.

2. When your slush is completely

chilled and ready to begin

freezing, small pieces of ice will

form on the evaporator, and you

will start to see these floating

around in the product.

3. The ice will slowly get thicker

and more dense, and the slush will

form.

evaporator

If you try to serve your slush, and its consistency is either too

solid or too runny, you can alter its consistency by adjusting the

torque setting on the back of the machine.

By turning this screw, you will

see the peg move between the +

and – positions.

If you want to make the product

thicker, move the marker toward

the + sign, which will increase

the ice crystals in your product.

When adjusting the setting,

move it gradually, or your

machine may over freeze, leaving

your slush too solid, or not freeze

enough, leaving it too runny.

This can be done by using a flat

head screwdriver. You will find

the adjustment screw on the

back of the square plastic panel

that is holding the evaporator.

4. When you have slush that is

fairly thick but is still being turned

by the spiral, your slush is ready to

serve.

1. The control switchboard for the Polar Krush machine is shown

below.

2. Left hand side freezer

3. On and Off switch

4. Motor - right spiral

5. Right hand side freezer

6. Rear light switch

This machine works in the same way as above, but also has a chill

switch that allows the machine to remain chilled overnight. If you are

using this setting, turn off the freezer switches (2,5) and turn on the

chill switches (3,6). Reverse in the morning to freeze down.

7. On and Off switch

1 2 3 4 5 6

The on/off switch (3) will light up when a power supply is available.

Switch the machine on, then switch both augers/spirals (1,4), and

both freeze buttons (2,5) on. You will notice that the freeze function

will not start for around 5 minutes after the augers are turning.

Please note that if the augers are switched off at any time, the freeze

function will cut out. This is to protect the machine – if freezing

continues and the ice forms a solid block, there is a risk of damage to

the machine when the auger is switched back on, as the ice will stop

the auger turning effectively.

The Control Panel

2. The control switchboard for the Devil’s Ice machine is slightly

different and is shown below.

Cleaning your Machine

2. Remove upper mixing arm by

applying gentle pressure on the

front end of the stainless steel rod

to remove from plastic location on

the inside front of the bowl.

1. Use the taps to empty the

product from each of the two

bowls into a suitable clean

container.

Remove the clear lids from the

bowls.

3. Remove the taps by pressing the

tabs at both sides of the tap and

easing them out of the shaft, pulling

upwards at the same time.

4. Unscrew the two bowl retaining

nuts.

‘O’ rings

5. Gently ease the bowls out of

their position by moving them

downwards and forwards.

Carefully release the bowl from

the red seal at the back, taking

care not to spill any syrup that

may be remaining in the bowls.

6. Unscrew the spiral retaining

nut, remembering to turn

clockwise as this has a left hand

thread.

Please note – when you replace

the spiral and retaining nut,

there is a shaped hole, you

need to ensure that the flat

part of the spindle is located

correctly.

7. The red bowl seal can now be

carefully removed from the

cylindrical evaporator, and the

white shaft seal can be removed

from the spindle.

8. Clean the cylindrical evaporator and the blue plastic tray

underneath with a soft damp cloth.

9. Wash all the loose parts with a sanitiser, taking care to follow the

manufacturers instructions. Do not use an abrasive cleaner on the

bowls as the plastic can be. A bottle brush could be used to clean the

inside of the tap tubes.

Please note that the flat face of the

seal is toward the machine and the

curved face is toward the bowl. You

will need to remember this when

you reassemble the machine after

cleaning.

10. When all parts have been

cleaned, reassemble the machine

in reverse order, making sure that

you lightly grease the red seal on

the edges of the grooves and the

inside back edge of the bowl that

will touch the red seal. This avoid

leaks will help assembly and make

the next removal much easier.

11. Before placing back on the

machine, grease the small white

shaft seal, packing it half full with

lubricant to prevent product leaks.

Wipe away any excess lubricant that

may have been squeezed out as the

auger nut is tightened in an anti

clockwise direction.

The O rings on the taps must also be greased to prevent leaks and

help the movement when dispensing product.

Your machine is now ready to use.

Cleaning the Filter

2. Gently ease off the back panel

from the top, taking care to avoid

damaging the screw thread. Then

lift the panel upwards and toward

you over the lower remaining lug.

The panel will then be free and can

be removed with the filter. Note

that the wide stainless steel

surround should face the machine

when replaced.

1. A removable filter is fitted to the

machines, so you will need access

to the back of the machine.

Remove the black plastic knob.

3. The filter can now be cleaned,

keeping away from any food

products, by gently cleaning with a

soft brush or washing with warm

soapy water.

Rinse and dry, then replace the

filter and rear panel and replace the

fastening knob

Regular cleaning of the filter will ensure a faster freeze down time,

save electricity and reduce unnecessary heat being generated by the

machine.

Problem Possible cause Solution

The space around the sides and/or back of machine is

inadequate for cooling airflow.

Allow at least 20 cm between the machine and anything next to it & keep away from heat

sources.

The filter and/or the item that looks like a radiator are

clogged with dust etc.

Turn the machine off. Remove the rear back panel. Using a brush or vacuum cleaner clean the

condenser and filter, where fitted.

The product dilution is incorrect. Check the product dilution, as stated on the concentrate bottle, if unsure change.

The level of the product in the bowl is too low, exposing

the spiral.

Top up level with correctly diluted product.

Check the fuse in 13amp plug. Replace fuse, as necessary. If problem continues, request service.

Check the power supply outlet. Replace fuse or consult an electrician, as necessary. If problem continues, request service.

Product is leaking from the

bowl.

One of the bowl seals is not correctly positioned or

lubricated.

Remove bowl, check seals correctly positioned and lubricate.

Product is leaking from tap.

Tap is stiff to operate.

Tap not positioned correctly or the seal rings lubricated. Remove tap, clean and lubricate the “o” ring seals, replace tap until it clicks into place.

Product is flowing into the

drip tray through drainage

tube.

The white shaft seal between the shaft and the spiral is

incorrectly fitted, worn, or not lubricated.

Remove and refit the seal, filling the cup of the seal half full of grease. Wipe away excess after

tightening the screw. (s ee page 4 of the manual)

The spiral and/or upper

mixing arm is not turning.

Spiral (auger) switch is not turned on. Turn on spiral switch. (N.B. machine will not freeze until spiral turning)

The red bowl seal is not in the correct position, causing a

squeak, or the gear teeth do not mesh.

Check red bowl seal is seated correctly.

The product dilution is not correct. Remove and replace.

The white shaft seal has not been replaced, is damaged,

or not greased.

Replace, or clean and half fill with grease.

Low level of product. Refill with product with correctly diluted product.

Gear teeth worn. Request service call.

Light switch is off. Turn on.

The bulb has failed. Request service call.

Machine is noisy after a repair

or service.

Machine makes a grinding noise.

This is perfectly normal when new parts are fitted. Allow time for the parts to bed in. If noise

persists after a day or so request a service call.

The machine does not cool

efficiently, but the

compressors are running.

The machine over-freezes,

stops or slows down the

movement of the spiral.

The spiral and/or the upper

mixing arm are creating

noises as they rotate.
