VCCA-20-P Condensate Pump for Plenum Applications
OWNER'S MANUAL
English
EN
The VCCA-20-P pump is designed to be used in plenum applications and is compliant with UL standard
UL2043, “Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed
in Air-handling Spaces.”
This condensate pump automatically removes condensate
water that drips from an air conditioner evaporator coil, refrig-
eration equipment coil, condensing furnace, or condensing
boiler. The pump is controlled by a float switch mechanism,
which automatically starts and stops the pump.
All models also include a high water level switch, which opens
a thermostat circuit when the pump reservoir is full, stopping production of condensate. Alternatively, this
switch can be reconfigured to close a circuit, which can operate an external alarm or relay, (purchased sep-
arately).
This product is covered by a Limited Warranty for a period of 12 months from the date of original purchase
by the consumer. For complete warranty information, refer to www.LittleGiant.com

• Do not use to pump flammable, combustible, or explosive fluids such as gasoline, fuel oil, kerosene, etc.
• Do not use in explosive atmospheres or hazardous locations as classified by the NEC, ANSI/NFPA70.
• Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface, or in water.
• When a pump is in its application, do not touch the motor, pipes, or water until the unit is unplugged or electri-
cally disconnected.
• If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of
power.

Questions and Answers

    What to do if condensate is overflowing from Little Giant VCCA-20-P Water Pump?
    • S
      Samantha SmithAug 5, 2025
      If the condensate is overflowing from the tank of your Little Giant Water Pump, several factors could be at play. First, ensure the pump is connected to electrical power, ideally a dedicated GFCI circuit. The liquid inflow might be exceeding the pump's capacity, requiring a larger pump. The high-level switch should shut off the A/C unit or signal an alarm if connected correctly; verify this connection. Make sure the pump is level to ensure proper activation. Also, inspect the float for debris or build-up, as a dirty float can be too heavy. Check the check valve for obstructions and ensure the outlet tubing isn't kinked or blocked. Clear any blockages in the impeller housing. If none of these steps work, the switch or motor may be defective, necessitating a pump replacement.

      If your Little Giant Water Pump doesn't start when the tank is full, begin by ensuring it's properly connected to a dedicated GFCI circuit. Check the circuit breaker or fuse and replace it if necessary. Inspect the float for debris or build-up, cleaning it to ensure it's not too heavy. Verify that nothing is obstructing the float's movement. If these steps don't resolve the issue, the switch or motor may be defective, requiring you to replace the pump.

    Why Little Giant VCCA-20-P will not shut off?
    • S
      Steven HarringtonAug 17, 2025
      If your Little Giant Water Pump will not shut off, start by checking for any obstructions to the float's movement and remove any debris. It's also possible that the liquid inflow matches or exceeds the pump's output capacity, requiring a larger pump. Ensure the high-level switch is correctly connected to the A/C unit or alarm circuit. If these steps don't resolve the issue, the switch may be defective, and the pump may need to be replaced.

    What to do if Little Giant Water Pump runs but does not discharge liquid?
    • J
      Jennifer ThomasAug 23, 2025
      If your Little Giant Water Pump runs but doesn't discharge liquid, start by inspecting the check valve for any obstructions. Also, consider whether the lift is too high for the pump's rated performance. Check the inlet to the impeller for any blockages and clean it if necessary. Finally, ensure that the outlet tubing isn't kinked or blocked, clearing any slime or debris from the tubing and cleaning the inlet and outlet piping.

    Why Little Giant VCCA-20-P does not deliver rated capacity?
    • D
      Dr. Daniel KellerAug 29, 2025
      If your Little Giant Water Pump does not deliver its rated capacity, start by inspecting the check valve for obstructions. Also, verify that the lift isn't too high for the pump's capabilities. Check that the supply voltage matches the nameplate rating. Lastly, inspect the impeller and discharge pipe for clogs, cleaning the pump and checking the pipe for scale or corrosion.
