After cleaning, rinse with a sterile wet cloth.
Before commissioning, well dry and ventilate the device because explosive gases may form during disinfection.
During each decontamination, ensure the protection of persons adapted to risks.
CAUTION in link with the risk of corrosion and damage of the unit
DO NOT use cleaners containing acid or chlorine.
In case of potential damages and corrosions following the use of not recommended cleansers, Froilabo accepts decline
all responsibility.

Pressure relief valve
Froilabo freezers have a pressure relief valve enabling the chamber to return quickly to ambient pressure, either after
door opening or CO
2
or N
2
injection.
Frequent door opening increase humidity in the freezer. It may result in ice forming in the air intake tube in which the
pressure relief valve is located. A set of calibrated foam blocks is located in the air intake tube to minimise this issue.
If the air intake tube is blocked by ice, opening the door becomes difficult.
If this occurs, remove the safety valve and the calibrated foam blocks and then insert a screwdriver (or other long, thin
object) in the air intake tube and push the ice into the freezer chamber. When possible, apply a spray of warm water
also allows to remove the ice.
Clean the pressure relief valve (on the side of the unit) and the calibrated foam blocks on a regular basis (everyone to
three months, as needed). Ensure that the valve and blocks are repositioned correctly. The foam set consists of 2 foams,
a thin on valve side and a thicker on tank side.
After a freezer shut down, remove the foam from the pressurization valve. Allow the foam to dry completely, or
use the spare set, before replacing the foam in the valve, and restarting freezer.
After injection of CO2 or N2, it is necessary to proceed to the disassembly of the decompression valve and to replace
the internal circular silicon membrane in the right direction to find a seal inside the valve.
4)
Air filter
In order to keep the refrigeration performance of the freezer optimum and prolong the life of the compressors, an air
filter is located on the front panel, in front of the condenser.
This filter must be cleaned of dust as often as necessary. To do this, simply remove the filter and wash it (using water
with no cleaning agents). After drying the filter (without wringing), put it back in place.
Freezers must not be operated without filters. If the filter is not in place, an alarm will be raised until the filter is back in
place.
Froilabo strongly recommend disposing of the filter and replacing it with a clean one. It will protect users from potential
contamination and reduce the risk of exposure.
