INITIAL START-UP AND OPERATION

 1. 

Test the installation for leaks by running water into the sump, allowing 

for normal operation of the primary pump.

 2. 

Check the controller. The System Ready light will be green when the 

unit is plugged into the 115 V wall outlet. The battery will indicate its 

condition when the controller has DC power. When the unit is first 

plugged in, all lights will flash and alarm will sound to verify all lights and 

the alarm work. The Fit controller powers up expecting both switches 

to be connected. If one or both float switches are not connected, 

there will be various alarms depending on what is connected. If this 

occurs, simply plug in both switches and then reset the alarms by 

holding the Silence button for 3 seconds. Note that the charger may 

not begin charging for several minutes.

 3. Disconnect the primary pump from its power source before touching 

any component in the sump pit.

  4.  Lift the Fit’s 

operational float switch. After 1 second “splash activation 

prevention” delay, the DC backup pump will run, and the alarm 

will sound after 1 more second. Lower the operational float switch 

after the alarm sounds. 

Take care that the intake of the DC pump is 

set above the intake of the primary pump. If water was pumped, the 

Yellow DC Pump LED and alarm will remain on, indicating that the 

pump ran and pumped water. The alarm can be silenced by pressing 

the Silence button. The yellow LED can be cleared by holding the 

Silence button for 3 seconds to reset. If the operational float is held 

on while there is no water to pump, the controller will turn the pump 

on and off a few times before running the pump continuous. This is to 

purge a suspected air lock. When the float is lowered, the pump will 

turn off, but the yellow DC Pump LED will not persist. The yellow DC 

Pump LED and alarm only stay on if the pump actually pumps water. 

The intention of this behavior is so the installer can turn the pump on 

and off for testing during installation without repeatedly having to reset 

the controller. If the operational float is removed/unplugged, there 

will be an alarm and a red flashing Float Status LED until silenced or 

remedied. If the operational float was never installed, the alarm and 

red flashing Float Status LED will occur for 4 hours and then turn off.  

If there is a need for the controller to disregard the operational float 

(for example, service or replacement), a Factory Reset can be initiated. 

Unplug the operational float and then hold the Test and Silence buttons 

together for 6 seconds. This will instruct the controller to NOT alarm 

for the missing operational float and reset the unit.

  

CAUTION

Continuous dry running may cause overheating and 

damage the pump seals. Upon release of the float switch, the pump 

will shut off. Be certain there are no obstructions around the float 

or stem that will prevent the switch from turning off.

 5. Check installation of the high water switch taking care that it is installed 

so that its “on” point is higher than the “on” point of the operational 

switch. Lift the high water float. After 1 second “splash activation 

prevention” delay the pump will turn on, the alarm will sound, and 

the light will alert of high water. If the operational float is down, and 

the DC pump is underwater, the pump will run until the float lowers 

and the pump is no longer pumping water, or the run timer expires. 

A float fault LED will be lit. During a float fault, the operational float 

is disregarded until the controller is reset. If the operational float is 

up during high water, unit will alarm and high water float light will 

illuminate. The pump will turn off once water is pumped lower than 

the operational float.
If the high water float is held on while the operational float is down 

and there is no water to pump, the controller will turn the pump on and 

off a few times before running the pump continuously. This is to purge 

a suspected air lock. If the high water float is removed/unplugged, 

the resulting controller and pump behaviors are the same as if it 

was turned “on”. The alarm and red Float Status LED will be on until 

silenced and reset, respectively. If there is a need for the controller to 

disregard the high water float (for example, service or replacement), 

a Factory Reset can be initiated. Unplug the high water float and then 

hold the Test and Silence buttons together for 6 seconds. This will 

instruct the controller to NOT alarm for the missing high water float.  

When a new high water float is received, simply plug it in and the 

controller will see it and monitor it from that point forward.

 

6.  Complete the final testing of your installation by ensuring the primary 

pump is still disconnected from power. Then, unplug the Fit controller 

from the 115 V wall outlet. Run water into the sump until the DC 

backup pump is activated by the operational float switch. Check all 

connections for leaks.

  7.  Push the Silence button when the pump is running. This will silence 

the alarm. The pump will continue to run until the operational float is 

deactivated.

  8.  Reconnect the controller and the primary pump to the AC wall outlets. 

The primary pump may come on, lower the water level in the sump 

back to its normal operating level, and shut off. Both primary and 

backup systems are now ready for use. Hold silence button for 3 

seconds to reset the Fit controller.

  9.  The battery LED will be yellow during normal charging operation. See 

page 6 and 7 for a description of controller functions.

    NOTE: When running the pumps, it is normal for a stream of water to  

spray out of the pump's 1/8" (3 mm) air relief hole. 

It is important to understand that the Fit controller is an advanced technology product that has capabilities beyond those seen in other battery backup 

products. For those unfamiliar with the product, behaviors in the Fit may initially seem unusual. For example, the controller is able to recognize potential air 

lock situations and remedy with an on/off/on/off/on routine proven to purge the problematic air from the pump. Further, advanced float logic enables the 

controller to sense other pumping issues such as a stuck float, allowing the system to take actions to prevent damage to equipment.  
The LEDs have specific patterns and behaviors that differ from other products on the market. For example, the DC Pump LED will stay Yellow after pumping 

water, alerting the homeowner of a DC pump-run event. If the pump runs and does NOT pump water (for example when lifting the float manually as a test 

with the pump above the waterline), the LED will not stay Yellow. This is meant to be an aid to the installer in order to test the pump without having to reset it 

each time.

When either float is disconnected, the alarm will sound and the Red Float Status LED will blink indicating that the float state has changed. Disconnecting 

the high water float will cause the pump to run. If there is an operational float fault diagnosed by the controller, you may notice that it no longer turns the 

pump on and off. This is because the sequence of prior events indicated that the operational float can’t be trusted (such as lifting the high water float while 

the operational float is down – this is illogical to the controller since water would always lift the operational float first), and the controller will rely on input 

from the high water float. Since the high water float does not have a sufficient pumping range, the controller will turn the pump “off” once 30 seconds have 

elapsed or the pump begins spinning in air. The Fit offers true redundancy for pump operation that competitor’s products do not have. 
Before leaving the installation site, the installer must initiate a Reset by holding the Silence button for 3 seconds. This will ensure that all systems are in a 

standby, ready state.
