4.1 Scheduled Maintenance
Proper and timely maintenance is crucial for trouble free functioning of any device and your Esco ULTF is no
exception to this rule. We strongly recommend that you follow the maintenance schedule suggested
hereunder in order to obtain optimal performance from your Esco ULTF.
Above is the minimum frequency. More frequent maintenance is required depending on actual condition of the freezer.
4.2 General Cleaning
Routine cleaning of freezer should be carried out. The surfaces can be cleaned by wiping down with clean
water and a mild detergent using a sponge.
4.3 Condenser Cleaning
Cleaning the condenser is one of the most important tasks
to ensure the unit operates properly and efficiently. A
clogged condenser often results in poor performance and
raised power consumption. In some cases, clogged
condenser can choke the system’s air intake and cause
severe damage to the compressors.
To clean the condenser, pull open the left and right bottom
doors. Use a household type of vacuum cleaner to vacuum
the fins. Make sure you can clearly see through the fins
after the vacuum operation is completed.
The condenser should be cleaned once every 6 months or
more frequently if the area is dusty.
4.4 Air Filter Cleaning
The air filters are the first line of defense against dust and
dirt that might be pulled into the condenser. It is necessary
to inspect and clean the air filters on a regular basis.
To clean the air filter, open both left and right bottom
doors, there are two air filters installed. Remove the
condenser air filter, and wash it in water. Dry it out and
place it back in the air filter holders.
The air filter condition should be inspected and washed once in every 3 months. Replace the filter if it is too
dirty or worn out.
