Preventive Maintenance Services

Preventive Maintenance Benefits

• Reduce equipment outages: Non-planned outages are significantly reduced mitigating product loss (food or other)
• Extend equipment life: Cleaning and tuning your gear will improve operational efficiency which reduces repair requirements and equipment replacement. Energy savings may also be observed.
• Mitigate risk of being shut down by food inspectors

High Level Sequence

1. Go to site to perform the Preventive Maintenance on equipment according to checklist(s) below
2. As a follow up to the Preventive Maintenance, KRS provides a report and sends quote(s) for any required additional actions such as parts replacements, ice machine descaling, etc.

1. On demand - email us or call us to request a PM 
2. Maintenance Contract - we set the frequency and scheduling up front and invoice you a flat rate per visit that you can add to your budget (frequency can be 2, 3 or 4 PMs per year)
3. We offer estimates upon receiving a list of equipment that requires maintenance

We require a list of your equipment to provide an accurate quote.

Preventive Maintenance Checklist For Refrigeration Equipment

1. Clean evaporator & condenser coils with high pressure nitrogen (includes roof top)
2. Check lines for condensation
3. Clean fan blades and fan cages and inspect the fan motor
4. Check the integrity of insulation, quote replacement if required
5. Check for air leaks through cracks, holes and worn parts like gaskets and seals
6. Lubricate door hinges where required
7. Insure proper closure/self-closing
8. Level unit
9. Check drain lines
10. Check all settings and ensure optimal operation

Preventive Maintenance Checklist For Gas Equipment

1. Perform temperature checks, calibrate where required
2. Inspect for oil or gas leaks
3. Doors open/close properly
4. Gas connection is secure
5. Gas hose meets regulations
6. Equipment must have its own a gas shut off valve
7. Gas equipment on wheels must have a wall restraint
8. Main gas shut-off valve must be clearly indicated and easy to shut off
9. Instructions on how to re-light each gas equipment after a shutdown are readily available

• Cleaning & Sanitizing: Use manufacturer-recommended, food-safe cleaners to remove mineral deposits (scale) from the water system, evaporator, and storage bin.
• Air Filter & Condenser Coil Cleaning: Remove dust, lint, and grease from air-cooled models to ensure proper airflow and prevent reduced ice production.
• Water Filtration: Inspect and replace water filter cartridges to prevent buildup.
• Inspection: Check for water leaks, unusual noises (grinding/clanking), and worn electrical components.
• Components: Lubricate moving parts and inspect the auger/bearings in flaker machines annually.

• Clean Filters: Remove and clean filter screens and baskets.
• Clean Wash/Rinse Arms: Inspect for blockages, ensuring all nozzles are clear for maximum water pressure.
• Wipe Interior/Exterior: Clean the machine’s interior walls, curtains, and exterior surfaces. 
• Descale/Delime: Remove mineral buildup (scale) from heating elements and interior surfaces, particularly in hard water areas.
• Check Door Gaskets: Inspect door seals for damage to prevent heat, water, and energy loss.
• Inspect Plumbing: Check hoses and drains for leaks or, blockages. 
• Calibrate Components: Check thermostats, chemical pumps, and control boards to ensure 180°F (82°C) sanitizing, temperatures.
• Water Quality Management: Monitor and maintain, water softening systems
