The Electrical Control Panel, located behind t h e right hand side panel and in t h e lower r ight corner, conta ins the components for t h e machine controlling circuit. This panel is t o b e accessed only by trained, exper-

..ienced technicians.

WARNING! DISCONNECT FREEZER FROM THE SOURCE OF ELECTRICAL SUPPLY BEFORE ATTEMPINC TO SERVICE.

The following is a n explanation o f t h e control panel components:

C OMPRESSO R C ONTACTO R - Activates the refrigeration compressor. When the machine is operated in the PRODUCTION mode, the.compressor contactor will be energized by t h e e lect ronic Hard'O-Ma t i c control (H.O.M.).

BEATER MOTOR CONTACTOR - Activates t h e beater drive motor. The beater motor -con tac to r is energized by t h e se lector switch when e i t h e r in the PRODUCTION, EXTRACTION o r CLEAN MODES.

OVERLOAD PROTECTOR - Senses t h e current (amperage) supplied t o t h e bea te r motor. In t h e event of a current overload, t h e protector will t r ip and s top the en t i re machine, The tr ip AMPS have been pre-set a t t h e factory and a r e indicated on t h e control panel cover. This device also contains t h e overload rese t mechanism. If reset is required, position the se lector switch t o t h e OFF position before pushing t h e reset button. Return selector switch to t h e desired mode.

ELECTRONIC HARD-0-MATIC (H.O.M.) - Automatically senses and controls product consistency when the f reezer is operaring in t h e PRODUCTION mode. Depending on signals received from t h e beater drive motor, t h e H.0.M. act ivates or stops the refrigeration system t o maintain pre-set product consistency.

CURRENT TRANSFORMER - Monitors bea te r motor current characterist ics and provides signal t o H.0.M.

TRANSFORMER (MAIN) - Steps down t h e primary 115 line voltage t o 24 volt secondary supply for the control circuit.

TERMINAL BLOCKS (1 15 Volt) - Inter-connection point for high voltage components, I.E. compressor, main transformer, beater motor, and condenser fan motor. Also, used to connect power supply wires.

The machine is now completely assembled and ready to be sanitized.

PACE 11

PART V SANITIZING THE FREEZER

Prior t o starting the freezer with the product t ha t will be served, t h e f reezer mus t be sanitized-

Sanitizing t h e freezer is most important as the procedure retards t he growth o f bacter ia and insures acceptable product test results when examined by local Heal th and/or Agriculture Departments.

The frequency of cleaning and sanitizing cycles must comply with local Health Regulations. If uncertain about the regulations in your area, contact the local Board of Health or Department of Agriculture.

To begin the sanitizing process, you wi l l need a clean pail, wire wisk, and a so f t plastic bristle brush.

1. Mix 2 9z. of sanitizer, STERA S H E E N 'GREEN LABEL O R EQUIVALENT, (sample packs included in the STXRT- UP KIT) into a pail containing one gallon of warm water. Dissolve sanitizer by stirring with a wire wisk, This formula will make a 200 P.P.M- (parts per million) concentration of chlorine sanitizing solution.

IMPORTANT: Do not exceed the formula recommended by the sanitizer manufacturer as i t wi l l not add to its effectiveness,

2. L i f t t h e fill chute cover and pour the sanitizing solution into the cylinder until t he solution rises in the fill chute.

3. Turn the selector switch to the CLEAN position for 30 seconds (Ref, Fig. 4, PC. 5 ) . The beater will run allowing the sanitizing solution to come in contact with all internal product contact areas- During ihe 30 second CLEAN period, the remainder of the one gallon of sanit- izing solution should be added filling the fill chute,

4. Turn the selector t o ihe OFF position.

5. Using a sanitized soft Srisile brush, brush the dispense chute, the underside of the fill cnute cover, and the sides of the fill chute that w i l l come in contact with product. Close the fill cover. Allow the sanitizing solution to remain in contact with the product areas for three ( 3 ) to five ( 5 ) minutes-

6. Place a c lean pail under the dispense chu te and slowly raise t h e dispense handle and g a t e cover t o dra in the sanitizing solution from t h e cylinder.

7, Allow the sani t izer t o drain completely, CIose the dispense handle,

HELPFUL SUGGESTION: When the sanitizer has stopped flowing f rom t h e dispense head, leave the dispense handle in the OPEN position znd tu rn t h e se lec to r switch t o t h e CLEAN position for two t o i h r e e seconds to assist in removal of the last b i t of sanitizer.

00 NOT RINSE THE idACHINE WITH FRESH WATER AFTER THE SANITIZING .PROCESS HAS BEEN COltlPLETEO AS THIS ACTION WOULD COIUPLETELY NEGATE THE ENTIRE PROCESS.

CAUTION: It is recommended t h a t the beater b e turned a s little as possible during the washing and sanitizing processes as excessive ro ta t ion c a n result in premature wear of bea te r blade surfaces;

PART V1 STARTING THE FREEZER.

Only a f t e r t h e machine has been thoroughly cleaned and sani t ized is the r'reozer ready f o r production o f the.initia1 batch,

You have t h e finest, fas tes t and most depenazble f reeze r nanufac:ured, Congratulations!. You a r e now re,ady t o make hard ice c ream, sherbets, ic-ts, g e l a t o and more, .

r

A successful1 re ta i l business depends entirely on the quali ty of t h e product it produces, Therefore you a r e urged t o choose wisely only quali ty increaients f o r t h e formulation or' your f rozen products- Please remember , inexpensive and inferior ingredients will result in a similar inferior product and a d i s a t i s f e d customer.

Please observe the Following recommendations:

1. Make your mixes from- hi& quality natural products o r obxain from a reliable and trust;vor;hy supplier.

2- 00 not serve the product :o the customer unless i ts quali:y and appearance 2r2 entirely sacisfac:ory.

3. 8e sure the machine is kept clean a t all times.

4. In t h e event t h e f r e e z e r requires service, always con tac t an authorized COLD ELITE Technician,

8 a t c h sizes will vary depending on the mix ingredients, desired overrun, etc,, Experience will be t h e t eacher for judging the desired size of each batch- F o r example, when making ices, a larger quantity o f mix may be poured into t h e cylinder as the final finished ba tch wi l l have less expansion due t o minimum overrun.

The initial quanti ty o f mix t o be.poured into t h e cylinder is a minimum or' 1.7 quar t s (54 oz,) and 2.2 quar ts 170 oz.1 maximum, As a guide, when charging t h e cylinder with mix, t h e horizontal mix level mark on the dispense head will indicate a fill of 1.9 quarts 160 oz.).

P repare 1.7 t o 2.2 quar ts of liquid mix, approximately 38O t o 42OF, in a clean, 'sanit ized measuring container.

PART VI1

OPERATING THE FREEZER

1. Pour t h e mix into t h e fill chute and close the chute cover.

2. Set t h e t imer t o 10 minutes and the se lector switch t o PROOUCTION. [Ref. Fig. 4, Pg. 5) .

3. Allow the machine t o f reeze the product t o the desired consisiancy.The t imer may produce an audible prior t o o r a f t e r t h e completion o f t h e freeze cycle. The 10 m i n $ ~ t e t imer se t t ing is an average. Exact timing must be arrived a t based on the mix used, desired overrun and firmness, and t h e consistancy control setting t o be discrrssed in PAST V l l l TECHNICAL INFORMATION.

4. On t h e initial batch when t h e timer sounds a t 10 minutes, turn t h e se lector switch t o EXTRACTION. lift the dispense handle and draw t h e finished batch from the cylinder into a sanitized, cold container. After dispensing is complete re turn the sa lector switch t o OFF.

Note tha t the second batch will be made in a lesser time. Again, exac t t iming must b e concluded based on t h e desired finished produc-i characteristics.

When working with different flavors, plan the saquence of batches before hand, Example, always s t a r t with vanilla, possibly cherry vanilla, vanilla chip, followed by coffee, walnut o r o ther light colored flavors. Naturally, chocolate would b e the final flavor dispensed.

PACE 14

Always remember t o use quali ty ingredients. Producing quali ty i c e creams, ices o r sherbe t s will guarantee a superior product and a happy customer.

MAINTENANCE

Your COLDELITE machine has been designed, engineered and manufactured t o achieve high performance and long durability.

The l i fe expectancy o f a machine, any machine, does not depend only on the qua l i t y o f i t s components and design, but also on the beneficial e f f e c ~ s o f basic procedures.

I t is important to you, therefore, to become famil iar with a k w o f these basic procedures:

. . " t - .. --:.-:, % ?:>'-* ,. h .:.-.v.*-: J.. -- ..,. ; . - . - 3

Remove '0' rings only w i t h the '0' r ing extractor supplied wlth the machine.

Clean the machine according to the instructions,+ . = - . G,-s.,r. . .. - -:_ - = _ -

Lubricate al l '0' rings and seals, as instructed,

The wearing or the improper cleaning o f the beater shaft seal, w i l l resul t in leakage from the rear- Check the dr ip t ray frequently and replace the seal when necessary.

Replace any '0' r ing that has a nick in it, If not replaced, it wi l l leak and in ter fere with the proper performance o f the machine.

When all the spare parts supplied with the machine are used, re-order immediately. Do not wait unt i l the part is required again-

NEVER use the AUTO position for washing, sanitizing and in i t ia l ly f i l l i ng the freezing cylinder.

IMPORTANT - During the washing and sanitizing period, run the machine only for t ime st r ic t ly necessary for this operation. Prolonged use o f the beater in the Cleaning position may causcl severe damage to the machine.

Always wash metal, plastic or rubber parts in lukewarm water. NEVER, NEVER USE HOT VJATEil!

I M P O R T A N T As the model LB-1008 i s an air cooled machine, i t s eff ic iency depends on the a i r cooled condenser. The fins of the condenser must be cleaned every t w o o r three months to assure efficiency.

W A R N I N G .-

Ext reme care must be taken when removing side, rear or control box panels.

Always turn the Se1ec;or Switch ro the OFF position. Also, turn o f f the Disconnect Switch on ihe eleca-iczl supply l ine before exposing any e lec t r i ca l connections and/or moving parts, such as belts, pulleys, fan blades and beater.
