INSTALLATION
WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service techni-
cian.
4. After installation is complete, check out product opera-
tion as provided in these instructions.
CAUTION
Do not use tools to adjust the EA122 or damage to the
vent may result. Use hands only to adjust vent. A
wrench may be used only on hex during installation.
LOCATION
Install the EA122A on the positive side of the circulator pump
at the point where air will accumulate. This is usually the high
point of the supply or the return main in the system as shown
in Fig. 3.
Fig. 3. Install EA122A at high point in system.
INSTALLATION
1. Fit EA122A vent in piping at a location as specified in
the Location section.
2. Turn EA122A until vent fits tightly on piping. Use a
wrench to securely tighten hex.
3. If safety drain connection is desired, install a pipe
between vent discharge and drain using Q122A1001
Safe Waste Connector.
4. Make sure that the red vent cap is securely tightened,
and that the valve is in the closed position by turning
vent body clockwise. See Fig. 4. Use hands only to
avoid damaging the vent.
5. With the valve in the closed position, flush the system
as required to remove dirt, debris and contaminants.
6. Fill the system with the appropriate solution.
7. Operate the EA122A by turning the air vent body coun-
terclockwise to the open position. Use hands only, see
Fig. 4.
8. Make sure the red vent cap is tightened all the way to
the stop position for proper leakage guard operation.
Use hands only to tighten.
Fig. 4. Turn vent body counterclockwise to open or clockwise
to close.

OPERATION
The EA122A operates as follows:
Opening the air vent (turning valve body counterclockwise)
exposes the EA122A to the system. Water and air may enter
the vent chamber. The float will fall through any air in the
chamber. This opens the vent seat.
The red vent cap allows air to pass through the open vent. As
the air is released through the vent cap, water replaces the air
in the vent chamber and the float rises. This closes the vent
seat. When additional air enters the vent chamber, the
operation repeats.
If the vent seat remains open, water will rise through the vent
and cause the swelling disks inside the red cap to close off
the vent. Closing the air vent (turning valve body clockwise)
isolates the EA122A from the system, allowing service.
SERVICE
CAUTION
The EA122A may be hot due to system temperature
extremes. Use caution when adjusting vent to prevent
burning hands.
Dirt may collect in the seat area of the air vent float assembly,
causing the vent to malfunction. Clean the vent periodically
to prevent this problem.
NOTE: The EA122A may be serviced without
depressurizing or draining the system.
To clean the seat area, proceed as follows:
1. Turn the vent body clockwise to the closed position,
isolating the vent from the system. See Fig. 4.
2. Remove the float assembly by unscrewing the outer
ring at the top of the body and lifting up the black cover
assembly. See Fig. 5.
3. Carefully clean any dirt or debris from the seat area.
CAUTION
Do not bend spring on float assembly or damage to
the vent may result.
4. Carefully clean any dirt or debris from inside the vent
chamber.
5. Replace the float assembly, making sure that the O ring
is seated properly (see Fig. 5).
6. Replace black cover assembly on air vent body.
7. Using hands only, replace outer ring, turning until hand-
tight.
8. Operate the EA122A by turning the air vent body
counter-clockwise to the open position. Use hands
only. See Fig. 4.
9. Make sure the red vent cap is tightened all the way to
the stop position for proper leakage guard operation.
Use hands only to tighten.

TROUBLESHOOTING
CAUTION
The EA122A may be hot due to system temperature
extremes. Use caution when adjusting vent to prevent
burning hands.
Problem Action
The EA122A is not venting
air or there is too much air
in the system.
1. Check the red vent cap; make sure the vent passage is open (disks are not swelled).
2. Check that the valve is in the open position.
3. Make sure that the float is attached to the vent lever as shown in Fig. 5.
Water is leaking from the
EA122A.
1. Make sure the red vent cap is tightened all the way to the stop position.
2. Adjust the valve to the closed position by turning the vent body clockwise.
3. Clean the vent as described in the Service section.
4. If internal parts appear damaged or deteriorated, replace cover assembly (part no. P122B1002).
