PM Checklist

Instruction Sheet
Crathco Granita Preventative
Maintenance (PM)
Checklist for Kit 90566
Serial # 11259 and above*
(and units with lower serial #’s that have been converted
to stainless steel shafts - units with black stainless shafts
will need to be converted using PM Kit #90110B)
A preventative maintenance visit should be performed every 6 months. In addition, air filter should be cleaned weekly, and every three months the
condenser should be cleaned, and the rubber bell shaped shaft seals should be replaced. Failure to complete PM’s every 6 months is considered abuse
of the machine, and therefore voids the warranty. Proof of PM must be documented with Grindmaster Corporation to maintain warranty coverage. To
document your PM, complete this form with signatures, place used/worn parts that were replaced during the PM inside envelope, and mail to
Grindmaster Corporation. Parts returned should include 2 evaporator seals, 2 rubber bell shaped shaft seals, valve o-rings and shafts (if applicable).
First PM on serial numbers 11259 to 12202 should also include kit number 90225 (one per serial number).
The following procedures should be performed during a preventative maintenance visit, using PM kit #90566 or 90110B.
Document model and serial number of equipment and record above.
Check product temperature and consistency for proper setting - adjust if necessary.
Insure product is being mixed properly and is within specification (check and document brix - most products should be around 13% - refer to
product manufacturer’s recommendations for exact recommended brix). Record brix reading here: Left Bowl __________ Right Bowl __________
Check for leaks at gaskets, o-rings, front shaft seal, etc.
Empty product from bowls and disassemble unit completely.
Clean and sanitize all disassembled parts.
Clean and sanitize top tray and freezing barrel.
Clean out condensation tube with sanitizer and long brush.
Check condition of all panels, bowls, lids - replace if necessary.
Check mixing rods and augers for wear, check mixing rod bearing for wear - replace if necessary.
Check for bowl knobs (two per bowl to lock down bowl in front) - replace if necessary.
Check operation of lights in lid and rear of unit (if equipped) - replace light bulbs if necessary.
Clean re-usable air filter. Check condition of filter and replace if necessary.
Clean condenser.
Check condition of bowl gaskets and replace if necessary.
Replace all o-rings on dispense valves and lubricate.
Check drive shaft. Replace if necessary, using PM kit #90110B in place of 90566 above.
Replace evaporator seal in front of evaporator. (Use brass tool, included, to slide seal onto shaft, and use the white tool to tap seal into place. Be
sure to lubricate seal with food grade grease first.)
Replace bell shaped rubber shaft seal on front of freezing barrel (generously lubricate inside seal).
Lubricate parts where appropriate (dispense valve o-rings, inside of shaft seal, inner rim of bowl where it meets with the bowl seal).
Re-assemble unit and refill with product.
Verify and document defrost timer setting and operation and time of day setting and adjust if necessary.
Check thermostat setting on MG models. Thermostat setting should be between 1-1/2 and 2.
Verify compressor operation and freezer controller operation.
Verify ventilation is adequate (8” on both sides and back).
Check electrical connections and wiring.
Check fan operation (1 condenser fan and 2 gear motor fans) and clean fan or blades if necessary.
Review proper periodic care and cleaning instructions (disassembly, cleaning, sanitizing, lubrication and re-assembly) with store personnel. Review
proper product mixing and handling instructions with store personnel. Demonstrate and train store personnel to follow proper procedures (stress
importance of store level maintenance such as lubrication and filter cleaning).
Make sure store personnel have appropriate supplies (lubricant and sanitizer) to care for machine.
