perform at least one complete blast chilling or shock freezing cycle. When done, instruct the client
on the correct use of the unit.

and the sight glass must be clear.
4. As soon as possible after the unit has been started, check the power consumption, the standard
pressure measurements and the operation of all the controls.
NOTE: The refrigerating system works on pressure. An electro valve mounted on the top of the
cabinet is controlled by the electronic controller. When the temperature of the air in the cabinet falls
to the programmed low temp setting, the electro valve will close (0 VAC) and the unit will pump
down. When the temperature of the air in the cabinet rises to the programmed high temp setting,
the electro valve will open and refrigeration will start.
