3. While the SET and MAINT indicators are illuminated, press the START/STOP
key.
4.8 Total Running Time
The control module of the Innova 4300 totals the time the shaker has been “ON” to
track hours of usage.
To display the accumulated running time:
1. Select HRS using the
SELECT key.
2.
Simultaneously press the
∆
and
∇
keys.
The SET and MAINT indicators will flash and the accumulated running time will be
displayed in hundreds of hours (i.e., “02” equals 200 hours; “102” equals 10,200
hours). This display will continue for 10 seconds and then default to the previous
mode readout.
4.9 MAINT Indicator Light
After 10,000 hours of operation, the MAINT indicator will light. Preventive
maintenance is recommended at this point. The light can be deactivated by NBS
Service Personnel. Alteration of the internal clock by unauthorized personnel will
void the warranty.
4.10 Vent
The Innova 4300 is provided with a vent to exhaust gas or allow small amounts of
ambient air into the chamber. The vent is located in the left side of the cabinet (
see
Figure 3 ).
When the knob is tight (in a clockwise position), the vent holes are sealed. Rotate the
knob counter-clockwise to open the vent.
