ual pump is “Enabled”. After ten minutes, the display
will revert to “Disabled”. If a longer run time is desired
the manual pump must be enabled again when the time
has elapsed. Manual oil pump control is only available
when the chiller is stopped. The Manual Pump key is
not displayed during system prelube, system run and
system coastdown.
