Piping Connections

Connect inlet and outlet tubing to the condensate pump as follows:
1. Cut end of pipe(s) from evaporator or furnace drain at a 45° angle as shown to prevent pipe(s) from
sealing closed when sitting against the tank's floor.
2. The pump will accept up to three drain lines, although care should be used to make certain that total
inflow does not exceed the rated output of pump. If more water drains into the pump than the rated
output, the tank will overflow. Route drain pipe(s) downward into one or more pump inlet opening(s)
one to three inches, ensuring no interference with float operation. Keep any unused openings closed
using the supplied cap plugs.
3. Install outlet tubing or piping onto outlet check valve and secure with hose clamp (not provided).
• Use 3/8" inside diameter maximum tubing or piping to prevent excessive flow back to unit.
4. Route outlet tubing or piping from pump straight up as high as necessary.
• Do not extend higher than 75% of the total dynamic head capacity of the pump.
5. From the high point, slope discharge line down slightly to a point above the drain area. Then, turn down
and route to a suitable drain at a point below or approximately level with the bottom of the pump, if
possible.
• This will produce a siphoning effect which will improve efficiency of the pump.
6. If it is not possible to slope the discharge line down, make an inverted "U" trap directly above the pump
at the highest point.
