REPLACEMENT INSTRUCTIONS
GENERAL INFORMATION
WARNING:
This unit should be serviced only by qualified service personnel.
To reduce the risk of electrical shock when servicing, turn off all power to the
pump/dispenser. Simply turning off the power switch in the electronic head will
not remove all power from the unit! All breakers that feed the unit should be
turned off. In submersible pump applications, turn off power to the submersible
pump and any other dispensers which use that submersible pump. AC power
can feed back into a shut-off dispenser when other dispensers share a common
submersible pump or starter relay.
All replacement procedures are written with the understanding that the Series 9800Q has been
opened for servicing. Electronic component access is detailed on the next page.
The numbers found in brackets [1] in the text can be used to find the associated balloon number
in the reference drawings.
