Air Line
1. Install the air line accessories as shown in
, page 8. Use adaptors as
needed. Be sure the air line supplying the
accessories is grounded.
a. The fluid pressure can be controlled with
either an air regulator (F) to control the air
into the pump, or with a fluid regulator (H) to
control the fluid out of the pump.
b. Install a bleed-type master air valve (B) close
to the pump. This valve is required in your
system to relieve air trapped between it and
the pump when the valve is closed. Be sure
the bleed valve is easily accessible from the
pump, and is located downstream from the
air regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious
injury from splashing.
c. Install a second air valve (E) upstream from
all air line accessories to isolate them during
cleaning and repair.
d. Install an air line filter (D) to remove
contaminants such as dirt, moisture, and oil
from the compressed air supply.
2. The air valve on the pump does not require
lubrication.
3. Install a grounded, flexible air hose between
the accessories and the pump air inlet (T). See
Technical Specifications, page 40
, to determine
the air inlet size of your pump. Use a minimum
1/2 in. (13 mm) ID air hose.
4. If desired, install an accessory Pressure Limit
Kit in the air line, close to the air inlet. See
, for the correct kit for your
pump size.
