ELECTRICAL
WARNING
Before servicing electrical components in the case or the doors or door frames make sure all power to case is off. Always
use a qualified technician.
Check voltage and amps drawn on (Page 17) to determine proper line and fuse or circuit breaker size. Check power supply for low
voltage. If voltage reads “120” with no load, and it drops below “107” when the compressor tries to start, it is an indication of too
small supply wiring or too long to run.
It is recommended that a separate circuit be run for each cabinet to prevent another appliance burning the fuse or tripping the
circuit breaker, causing loss of product.
WARNING
The cabinet must be grounded.
Maintaining your equipment.
Planned Preventative Maintenance (PPM), also referred to as planned maintenance, is a pre scheduled maintenance routine, set
out to ensure that your Refrigeration equipment is maintained and working efficiently.
Most service companies offer this service and will be glad to get you set up. The Frequency of this PPM will depend on your site
conditions.
Most PPM contracts are scheduled
Monthly
Quarterly
Annually
Failure to keep your unit maintained can result in breakdowns and possibly voiding your units warranty.
Here is a list of some things that need to be checked although some programs vary pending needs and application.
The condenser coil needs to be cleaned
The condensate drains need to be cleared
Fan motors and blades need to be cleaned of dirt and debris
Inspect electrical connections
Check door gaskets
Monitor temperature and cycling
Operational characteristics should be logged so they can be compared during future visits.
Inspect Compressor and start components
