INSTALLATION
5. Connect the leads from the control charger to the battery terminals. White
positive (+) lead to positive terminal and black negative (-) lead to negative
battery terminal. Upon proper connection, test alarm will sound. Press
alarm reset to silence. This indicates proper charger to battery connection.
CAUTION
Correct battery hook up is essential for operation of the
system. Use nuts supplied with battery and eyelet connectors on battery
wire leads. On batteries with different sized posts, the positive terminal
is the larger post, 3/8” (10mm) diameter. The smaller post, 5/16” (8mm)
diameter is the negative terminal. This will be indicated on the battery.
Apply grease to the terminals to help prevent corrosion.
6. Connect the plugs for the pump, operational switch, and power supply into
the appropriate receptacles on the controller.
7. Close battery box and secure cover.
8. Plug the control power cord into the 115 V wall outlet. The primary sump
pump and the control charger should be on separate circuits.
9. Reconnect power to primary sump pump.
1.
The installation kit includes the necessary fittings and parts needed to install
as in Figure 1. A check valve is incorporated in the discharge of the backup
pump.
2. Select location for battery and control charger. Control charger must be
within 6' (1.8 m) of a 115 V wall outlet and within 6' (1.8 m) of pump and basin.
Connect to a separate circuit, different than the primary pump.
3. Make certain the float switch clamp is tight on the pipe to avoid slippage.
Ensure that the “off” level of the float is 1" (25 mm) minimum. above the
discharge tee of
the DC backup pump (see figure 1). Position pumps in the
sump and move float up and down, making sure of free movement without
interference from any obstructions inside the sump or lid. Very shallow sumps
may require some adjustment to avoid overfilling or backing up of water into
the sump inlet. The float switch can be moved on the discharge pipe or the
rubber stops can be adjusted as necessary. Cut extra float rod length below
lower float stop to prevent debris from interfering with float operation (see
Figure 2).
4. Mount the Key controller to the wall. If more convenient, the control charger
may be set on a nearby shelf or ledge. The Key controller can also be
mounted to the mounting posts on top of the battery box lid.
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 Key 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 the switch
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 Key
’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 continuously. 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.
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.
6. Complete the final testing of your installation by ensuring the primary
pump is still disconnected from power. Then, unplug the Key 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. Press 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 Key
controller.
9. The battery LED will be yellow during normal charging operation. See
page 6 and 7 for a description of controller functions.
It is important to understand that the Key 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 Key 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.
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 the float is disconnected, the alarm will sound and the Red Float Status LED will blink indicating that the float state has changed. 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.
