Drawing # Description Page
Appendix B Field Wiring Diagram 9
Appendix C Field Piping Diagram 10
2.1 Place the unit preferably on a concrete floor or base.
Level the base in both directions by placing steel
shims between the base and the anchor bolts.
2.2 A well-leveled and secured unit will result in quiet
operation as well as longevity of service.
2.3 See drawing Appendix C for general piping require-
ments.
2.4 Eccentric increasers can be used in the suction line
when increasing the pipe size. The straight side of
eccentric reducers should be installed on top to elim-
inate air pockets. Support the suction and discharge
lines independently by the use of pipe hangers or
anchors. Do not attempt to spring the suction and
discharge lines into position.
2.5 The power supply required for the unit is indicted on
the nameplate located inside the control panel. A
dedicated ground wire must be connected to the unit.
Single phase motors have internal overload protec-
tion. The disconnecting means and short circuit pro-
tection are to be supplied and mounted by others.
2.6 For units installed with an optional tank, the tank
must be installed per the requirements of drawing
Appendix C. Fill the tank per the tank prior to putting
the unit into service.
WARNING: Heavy load, may drop if not lifted properly.
Do not lift the entire unit by the motor eyebolts. Lift
the unit with slings placed under the unit base rails. FAIL-
URE TO FOLLOW THESE INSTRUCTIONS COULD
RESULT IN SERIOUS PERSONAL INJURY, DEATH,
AND/OR PROPERTY DAMAGE.
CAUTION: The Residential fire pump package includes
a high pressure relief valve. Make sure the discharge
of the valve is directed to the floor drain before making the
unit operational. FAILURE TO FOLLOW THESE INSTRUC-
TIONS COULD RESULT IN PROPERTY DAMAGE
AND/OR MODERATE PERSONAL INJURY.
Section 2 - Installation Instructions

lug provided in the enclosure to avoid potential safety haz-
ards. FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS PERSONAL INJURY,
DEATH, AND/OR PROPERTY DAMAGE.
CAUTION: Seal damage may occur. Do not run
pumps dry. Fill and vent the pump volute prior to
operation. FAILURE TO FOLLOW THESE INSTRUCTIONS
