ACTIONS TO TAKE AGAINST POWER FAILURE

If the main power fails, take the following actions.
Re-start using the Control Panel
located on the chiller-heater. Monitor
until chiller-heater returns to normal
operation. Purge directly from the
absorber. Stop the machine to ensure
the dilution operation takes place. The
dilution operation takes approximately
15 minutes.
