D. Alarm:
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires
or remove ground prong from attachment plugs.
Failure to properly ground the pump system can cause
all metal portions of the pump and its surroundings to
become energized.
All electrical and safety practices shall be in accordance
with the National Electrical Code
®
, the Occupational
Safety and Health Administration, or applicable local
codes and ordinances.
IMPORTANT:
The alarm panel, as an integral part of this
complete unit, is supplied with its own separate
Installation/Operation/Maintenance manual. Ensure receipt
of this manual, and that it is read and understood prior to
installing this unit. Familiarity with the plugger box manual
is critical.
A separate 115V branch circuit is required for the alarm
circuit. Do not split the incoming pump power circuit to
power the control circuit.
Connect the grinder pump leads and the float switch
leads to the plugger box in accordance with the
instructions included with those units.
E. Float Switches:
The pump cycle is preset at the factory
at 7" (approximately 13.5 gallons). The pump cycle can
be adjusted by loosening the cord grip and moving the
“on” float up or down. Adjustments of more than 3" in
either direction are not recommended—call customer
service if the pump cycle needs to be adjusted beyond
this recommended level.
F. Testing and Startup:
Follow the testing and startup
procedures found in the pump and plugger box
manuals.
G. GR20 Guide Rail Assembly:
The GR20 quick
disconnect assembly provided with the grinder
package system is designed to allow easy installation
and removal of the pump. Ensure that installation is
done per Figure 2 and Figure 3.
