This key allows the oil pump to be manually activated.
The oil pump will run for ten (10) minutes when man-
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.

ted to operated at to be adjusted. This setting can be

ten you want the oil pump to come on when the chiller
