12.4 Defrosting the Chamber
1. Remove all product and place in another freezer.
2. Turn the unit off and disconnect from the power source.
3. Open all doors and place towels on the chamber floor.
4. Allow the frost to melt and become loose.
5. Remove the frost with a soft cloth.
6. After defrosting is complete, clean the interior with a non-chloride detergent.
Rinse thoroughly with clean water and dry with a soft cloth.
7. Plug unit in and turn power switch on
8. Allow the freezer to operate empty overnight before reloading the product.
12.5 Cleaning the Door Gasket
The door gasket should be cleaned monthly.
Using a soft cloth, remove any frost build-up from the gasket and door(s).
The door gasket may need to be cleaned more frequently if dirt or excessive frost
build-up prevents the door from closing properly.
12.6 Vacuum Relief Port
The exterior door gasket provides an excellent seal to protect product, provide an energy
efficient thermal barrier to keep cold air in and room temperature air out, and reduce
frost build up on the inner doors.
Because the door gasket seals so well, a vacuum can be created after a door opening.
Warm air enters the cabinet, cools and contracts, creating a vacuum that pulls the door
in tightly against the seal.
To equalise the pressure inside the cabinet after a door opening requires 1.5-3.0 cu.ft.
of ambient air to be drawn into the cabinet. The amount of air required to equalise the
pressure varies depending on the cabinet size, cabinet temperature, duration of door
opening, inventory volume and the temperature/humidity of the ambient air.
The unit is designed with a "vacuum relief port" that allows the pressure to be equalised.
The time required to draw 1.5-3.0 cu.ft. of air into the cabinet depends on two factors:
1.
the size and number of paths available for the air to enter the cabinet, and
2.
the pressure difference between the internal cabinet and the ambient room.
Cabinets with the vacuum relief port operating normally, (i.e. vacuum relief port is not
iced over) will require a minimum of 30 seconds up to a maximum of 120 seconds for the
cabinet to equalise. This is also a good indication that the exterior door is well sealed.
