Weekly Checklist 

 

Weekly or Monthly Calibration and operation of all controls (high- and low-pressure switches, oil 
pressure switch, etc.) are within limits. 

 

Cooling tower spray nozzles and pump suction screen are free of scaling and algae (consult water 
treatment suppliers for corrective measures). 

 

Water distributors at the top of the freezer are free of scale accumulation. 

 

Remove solids that have collected in the water tank.  

 

Check all motor drive units (compressor, pump motors, cooling tower fan, and pump, etc.) for abnormal 
noise and/or vibrations. 

 

Observe one complete ice making cycle, record data, and compare with the 

Warranty 

Registration/Start-Up Form

. 

Monthly or Yearly Checklist 

 

Check entire system for leaks. 

 

Check system for leaks after 400 hours or 4 weeks of operation. 

 

Drain water from the condenser and cooling tower and check condenser tubes. Inspect for damage by 
corrosion or scale. 

 

Remove all rust from all equipment, clean, and paint. 

 

Check all motors for shaft wear and end play. 

 

Check operation and general condition of all electrical controls, relays, motor starters, and solenoid 
valves. 

 

Observe one complete ice making cycle, record data, and compare with the 

Warranty 

Registration/Start-Up Form

. 

 

Change oil in cutter motor gear reducer. 

 

 Warning: 

Pressure relief valves must be replaced after 5 years of service. Before replacing relief valves, 

review requirements per current local and national codes. Valve replacement should be performed only by 
service personnel experienced and certified in refrigeration and qualified to work with high-voltage electrical 
equipment. If a relief valve discharges, the valve must be replaced before putting the machine back into service. 
Relief valves do not properly reseat after a discharge event. Contact Vogt SuperCare Customer Service for 
replacement valves.
