Installation of Pre-assembled Backup
System on a Common Discharge
(For 12 VDC Backup Systems SPBS-10HF-6 and SPBS-12HF-10 with included 115 VAC Primary Pump)
s WARNING
!
WARNING
Comply with all national and local electrical and plumbing codes when
installing this unit. Disconnect power from all electrical equipment housed within the sump system
before working on or around the sump pump or battery backup system beginning with 115 VAC
powered pumps, level switches, and charger controllers; followed by DC powered items. Includes all
items such as pumps, level control switches, Charger/Controller Unit, and battery systems.
s WARNING
!
CAUTION
Reduction of plumbing sizes from what is used for the discharges of the primary 115 V and 12 VDC can
result in system under performance. Discharge piping that is of insucient size can result in premature pump and/or system
operation failure.
Included in the SPBS-10HF-6 and SPBS-12HF-10 kits:
1. 12 VDC backup pump
2. 115 VAC primary pump
3. Battery charger/controller
4. Battery case (battery not included)
5. (1) 1-½" street elbow near 12 VDC pump
6. Coupling for 12 VDC pump discharge
7. Check valve for 12 VDC pump
8. Switch to control 12 VDC pump
9. Check valve for 115 VAC pump
10. Discharge pipe “wye” assembly connected to the
12 VDC pump and 115 VAC pump
Customer required to purchase separately:
1. 12 VDC deep cycle battery – BCI Group 27, rated
85 – 140Ah, Lead-acid or AGM
2. Pipe and coupling or check valve (For connection to
drain pipe from household plumbing to discharge
pipe “wye” assembly)
3. Waterproof adhesive for plumbing connections

Pre-assembled with Common Discharge Pipe “WYE” Assembly
Step 1
a. Remove all debris from the sump basin.
b. Conrm that all exible couplings and hose clamps are properly seated and tight on the PVC plumbing discharge piping that is
part of the sump pump backup system.
c. Place the sump pump backup system into the sump pit/basin. Support both pumps as the assembly is lowered into the
basin. Do not use the PVC plumbing as a handle during this process as the connections might come loose.
d. The connection from the discharge pipe “wye” assembly to the drain piping from the home must be made so as to ensure
that both the 115 VAC primary pump and the 12 VDC backup pump rest at on the oor of the sump basin when the plumbing
is completely assembled and to align connection to the drain piping from the home. Dry-t the assembly to conrm prior
to gluing (see Figure 5).
e. Once dry-t conrms that both pumps rest at on the sump basin oor and the wye assembly piping aligns with drain piping
from the home, secure all connections by applying approved waterproof adhesive to all necessary joints and conrm that all
exible coupling hose clamps are fully engaged with plumbing and fully tightened.
s WARNING
!
CAUTION
For proper pump operation the exit point of all drain piping from the home must be lower or sloping away,
from the discharge plumbing’s highest point. Improper water drainage can allow freezing within the line leading to system or
component damage or failure.
s WARNING
!
CAUTION
Ensure all hose clamp connections and threaded connections are tight and that all plumbing slip t
connections are properly glued prior to starting the sump pump system. Failure to do so can result in damage to pump system
and/or cause property damage due to ooding.
s WARNING
!
CAUTION
Do not install or store the pump where it will be exposed to the weather or to temperatures below freezing
or damage to the pump will occur.
