INSTALLATION
When Installing This Product…
-
Read these instructions carefully.
Failure to follow them could damage the product or cause a hazardous condition. -
Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.
-
Installer must be a trained, experienced service technician.
-
After installation is complete, check out product operation as provided in these instructions.
CAUTION
Do not use tools to adjust the EA122A 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.
SAFETY CONNECTION FOR PIPING BETWEEN VALVE DISCHARGE AND DRAIN
INSTALL EA122A AT HIGH POINT IN SYSTEM
Fig. 3. Install the EA122A at high point in system.
INSTALLATION
- as specified in the Location section.
- Turn EA122A until vent fits tightly on piping. Use a wrench to securely tighten hex.
- If safety drain connection is desired, install a pipe between vent discharge and drain using Q122A1001Safe Waste Connector.
- Make sure that the red vent cap issecurely tight, 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.
- With the valve in the closed position,flush the system as required to remove dirt, debris, and contaminants.
- Fill the system with the appropriate solution.
- Operate the EA122A by turning the air vent body counterclockwise to the open position. Use hands only. See Fig. 4
- Open red air vent cap one full turn counterclockwise for proper automatic operation.
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.
Closing the air vent (turning valve body clockwise) isolates the EA122A from the system, allowing service.
CAUTION
The EA122A may be hot due to system temperature extremes. Use caution when adjusting vent to prevent burning hands.
The EA122A may become accumulated with dirt in the seat area of the float assembly, which may cause the vent to malfunction. Periodic cleaning is recommended to prevent the vent from malfunctioning.
NOTE: The EA122A may be serviced without depressurizing or draining
the system.
To clean the seat area, proceed as follows:
-
Turn the vent body clockwise to theclosed position, isolating the vent from the system See Fig. 4.
-
Remove the float assembly by unscrewing the top of the body and lifting the black cover assembly up. See Fig. 5.

CAUTION
Do not bend spring on float assembly or damage to the vent may result. -
Carefully clean the seat area of any dirt or debris.
-
Carefully clean any dirt or debris from inside the vent chamber.
-
Replace the float assembly, making sure that the O-ring is seated properly. See Fig. 5.
-
Replace black cover assembly on air vent body using hands only until handtight
-
Operate the EA122A by turning the air vent body counterclockwise to the open position. Use hands only. See Fig. 4.
-
Make sure the red vent cap is open (one full turn counterclockwise from closed).
TROUBLESHOOTING
CAUTION
The EA122A may be hot due to system temperature extremes. Use caution when adjusting ventto 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 it is open one full turn; make sure the vent passage is open.
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. Adjust the valve to the closed position by turning the vent body clockwise.
2. Clean the vent as described in the Service section.
3. If internal parts appear damaged or deteriorated, replace cover assembly (Part No. P122B1010).
