pump. The life of this battery will depend on
the amount of time that power is lost during
the lifetime of the pump and the average
ambient temperature. Because of the
extremely low power demands of the DR-
2000 it may never be necessary to change
this battery. If this battery does go dead, the
clock will revert to the default time of 12:00
AM of Day 1 and all programmed events will
be erased after a power loss. A replacement
battery can be purchased commercially. See
the Periodic Maintenance section for more
information.
OPTIONAL LOW LEVEL ALARM KIT
An optional low level (sonic) alarm and low level alarm lance
are available (see Spare Parts list).
The low level alarm lance is inserted into the chemical drum and
the sonic alarm is installed on the left side of the pump housing.
Both are wired into the appropriate connectors on the main PCB.
The lance detects when the chemical drum is empty and the
sonic alarm issues an audible alarm.

Refer to the installation instructions in the low level alarm kit
for more detailed instructions.
