 1.  Dc pump won’t run
 

(a)  Check fuse in line from control box center to the battery (see fig. 5) 

If fuse is blown, replace.

 

(b)  Check for proper connections.

 

(c)  Check all wire terminal points. Clean if required.

 

(d)  Check for low battery. Service battery if required.

 2.  pump runs but pumps very little or no water. 
 

(a) Check for weak battery. Weak battery slow pulse alarm will sound 

and “yellow” light will blink.  Battery will recharge if “Red” power 

“on” light indicates power has been restored and the float switch 

is in the off position.

 

(b)  If immediate usage is required, remove and replace dead battery 

with a full recharged battery or place an additional battery in parallel.

 

(c)  Due to varying conditions, the pump may continue to run on a weak 

battery without sufficient power to remove water before the low battery 

alarm is activated.  Pump will stop running when low battery alarm 

is activated.

 (d) 

 Weak batteries can be recharged but may not store 

sufficient energy for full service. A weak recharged battery can only 

be detected by reduced pumping time or by checking each cell with 

a hydrometer. If your emergency pump system is used frequently, 

the battery should be checked by a qualified battery dealer.

 3.  pump cycles too frequently.
 

(a)  Check tether length on variable level float switch.

 

(b)  Lengthen tether as required. 4" recommended for standard 

installations.

 4.  Float switch in “on” position. pump won’t run.
 

(a)  Remove pump. Check for obstruction in pump preventing impeller 

from rotating.

 5.  pump runs, but pumps water intermittently.
 

(a)  Pump is air locking. Check flow of water incoming to sump. If 

water is entering the sump at a high velocity creating a turbulent 

condition, a mixture of air and water may cause a complete 

or partial air lock and reduce or stop the flow of water in the 

discharge pipe.

 

(b)  Baffle the incoming stream of water to reduce turbulence. Diverting 

water stream against wall of basin usually corrects an air lock 

problem.

 6.  Water level high, pump startup delayed.
 

(a)  Battery is weak, if battery terminal voltage has dropped to 10.5 

volts, the control box automatically shuts off the system for 

10 minutes and activates the low battery fast pulse alarm. If 

main power supply is off, a good quality battery may recover 

without recharging if the float is in the “off” position, and allow 

some additional pumping time. If main power supply is “on”, the 

primary pump will lower the water level and the battery will begin 

recharging.  The battery is low if battery terminal voltage drops to 

8.5 volts.  The control box automatically shuts off the system and 

activates a fast pulse alarm.  The system can not be restarted 

until power is restored and the battery recharged.

 

(b)  If power has been restored and water in sump remains high, 

check primary pump. Service if required.

  

(c)  A completely drained battery may require 18 hours for a full charge.

 7.  Alarm sounds during battery recharge cycle.
 

(a)  Push alarm reset (max. 3 times). If condition persists, replace battery.
