Routine Maintenance & Troubleshooting
Cleaning Exterior Surfaces
Only mild detergents and water or an approved cleaner should be used on the painted surfaces of your Low
Temperature Cooler.
Cleaning the Refrigeration Condenser Fins
To keep the refrigeration system operating at optimum cooling capacity, the refrigeration condenser fins located
behind the front grill holes should be kept free of dust and dirt. Accumulated dust should be blown out periodically
using clean, dry compressed air.
Draining Residual Oil from the Immersion Probe Assembly
A thin film of oil may build up within the Immersion Probe Assembly with extended use and adversely affect the
Immersion Probe Cooler’s cooling efficiency. To ensure maximum cooling performance, we recommend that this
oil be drained from the Immersion Probe Assembly after every 200 hours of use or whenever you see a drop in
cooling performance.
1. Place the Power Switch / Circuit Breaker in the OFF position.
2. Elevate the Immersion Probe Assembly as high as possible above the enclosure for 10 to 15 minutes to
allow residual oil to drain back into the compressor. Do not allow the assembly to twist or dip as oil may
pool internally in these areas.
CAUTION:
Moving Immersion Probe Assembly while unit is operating may result in damage.
IMPORTANT:
Should you experience frequent drops in cooling performance due to the
accumulation of oil in the Immersion Probe Assembly, verify that it is properly installed, without
any twists.
