5.5 Operating the unit

5.5.1 General

CAUTION!

UTION!

UTION!

At initial start-up or when restarting after a service stop, the main power switch must have been on for at least 12

hours before starting. This is necessary to remove any ice build-up inside the unit.

CAUTION!

UTION!

UTION!

Before starting the unit, the reactivation air inlet and wet air outlet must be thoroughly checked. Any ice must be

removed. To avoid malfunction, it is important to have clear air passage throughout the ductwork.

When the unit is installed into the freezer and the reactivation circuit is connected, the connections have
to be blocked until the unit can be started. If this is not done there is risk that there will be ice build up in
the reactivation piping.

Before starting the unit, make sure that the reactivation ducting is free of ice.

Power must be connected to the unit as soon as possible to keep the reactivation fan free of ice (heater
inside).

Unless the power is connected immediately upon installation, wait a minimum of 12 hours prior to the start
of the unit.

5.5.2 Start

1. Ensure the power connected indicator is illuminated
2. Operate the mode switch on the Operator´s panel to the MAN position.

NOTE!

The reactivation air fan and reactivation heater will start immediately and will be running for approx. 5

minutes before the process air fan and the drive motor for the rotor start operating.

3. Check that the following indicators are on:

Power connected indicator

Unit running indicator

Both reactivation heater indicators

Process and reactivation air fan indicators

Drive motor indicator

4. Allow the unit to run for approximately 10 minutes to ensure that the operating conditions have

stabilized and check that the reactivation heater is operating (temperature indicator displays reactivation
air temperature).

NOTE!

If the reactivation air temperature is not indicated at all or does not reach above the first quarter of the LED

bar graph the reason might be that the airflow is too high. See Airflow Check and Adjustment.

5.5.3 Restart after power failure

When the power is removed from the unit, or there is a unit stop due to a unit malfunction, the reactivation
flow and heater is also stopped.
