l when initial storage capacity is larger, should be taken to gradually reduce the temperature setting, each step temperature 10 ℃, insulation - 7 10 hours, until the temperature.

l cryogenic freezing storage tank is used to save the general biological products, ultra-low temperature freezer storage tank is not a rapid cooling device, high water content in advance best refrigerated after cooling.

l don't close to the metal edge blade when in storage plastic products, plastic bags to avoid scratches.

l body cleaning: cleaning cryogenic refrigeration storage tank inside and outside surface application non-corrosive neutral cleaning agent, after cleaning, wipe with dry cloth.

l often wipe a little talcum powder on sealer can prolong the service life of the sealing strip.

l cryogenic freezing storage tank long runs, and the side wall in the cabinet door, cabinet mouth easy to frost deposit, the frost layer thickness will affect the sealing performance and cooling performance, please use the match regular defrosting defrosting a shovel, and cadres to wipe clean.
