Your freezer will require some basic maintenance to stay in good, working condition:

• Regularly remove any frost buildup by using a wooden or plastic scraper
• Freezers that are equipped with an air-cooled condenser need to be cleaned of dust and debris at least once a year (or more often if the freezer is located near excessive dust and dirt)
• Clean off any debris with careful vacuuming or forced air
• Check and replace batteries on Sonalarm and Chart Recorders (if equipped) regularly

You should start by clicking on the "Cleaning the 1.0 Condenser" button. This will give you a step-by-step direction sheet that explains how to get to your unit’s condenser.

First, remove any products from inside your freezer. Then, unplug the freezer so it is disconnected from electricity. Open the lid or leave the door open. As the freezer warms up, you can remove any loose frost. After the frost is entirely removed, wipe away the moisture. Let the freezer airdry before plugging it back in for usage.

For Ultra Cold Series freezers, please allow them to defrost and warm up for at least 24 to 48 hours before plugging them back in.

As soon as frost begins to accumulate, remove it gently with a plastic or wooden scraper. When frost build-up is not removed on a regular basis, you could have problems. The door seal might fail, and your plastic door lining could crack if the door is forced shut with thick frost. Your freezer may also not maintain your desired temperature with frost build-up.

No, you should never drill holes in your freezer. If you do, you risk hitting a refrigeration line. In most cases, this damage cannot be repaired. If you want an access port, they can typically be installed at the time of your order. The cannot be added later. Please not that drilling a hole in your freezer voids your warranty.

For our Moderate Cold Series and Super Cold Series freezers, we use R404A. For our Ultra Cold Series freezers, we use R134A (High Stage) and R508B (Low Stage) refrigerant.
