BENDIX SD-08-2403 Manuale Utente

4. Position the end cover as marked during removal and

install the retainer ring so that the gap in the ring is
within an inch of  the notch in the body.

5. Grease the threads on the three cap screws and reinstall

them with their retainers in the end cover.

6. Reconnect the air control line to the purge valve port in

the end cover.

7. Reconnect the thermostat and heater wire.

8. Test the air dryer as outlined under the Preventive

Maintenance and Checking Serviceability Section of this
manual.

1. Install the air dryer in the compressor discharge line as

close to the supply (first) reservoir as possible. The
discharge line between the compressor and air dryer
must not exceed 20 feet in length nor less than six feet
in length for a two cylinder compressor or ten feet in
length for a single cylinder compressor. Six feet of
discharge line and a 90 cubic inch reservoir can be used
in lieu of ten feet of discharge line for single cylinder
compressors.

The discharge line should slope downward from the
compressor to the air dryer inlet to avoid water traps
and to allow drainage to the air dryer. (If  the 90 cubic
inch reservoir is used, it should also be mounted and
plumbed to avoid water traps and to allow drainage into
the air dryer.) Discharge lines may be either be copper
tubing or high temperature hose. However, Bendix
compressors require a minimum of four feet of copper
tubing extending from the discharge port. The balance
of the discharge line may be either copper tubing or
high temperature hose.

2. Locate outside the engine compartment in an area of

air flow when the vehicle is in motion. Do not mount
near exhaust system or other heat-producing
components and avoid road-splash areas. Provide 20
cm (8 in.) clearance below dryer for servicing.

3. Mount vertically, with purge valve exhaust toward the

ground, away from the frame and other components.
Connect a hose to the exhaust cover if  necessary, since
this valve may expel rust and scale particles as well as
condensate and oil collected in the dryer.

4. Connect the purge valve control port to one of  the

governor unloader ports. This line should be routed such
that no water traps are formed.

5. For the dryers with a 3/4-14 or 1 - 11-1/2 dryseal outlet

port, a check valve must be placed between the purge
volume and the first downstream reservoir. (Dryers with
1/2-14 dryseal outlet ports have a built-in check valve.)

6. Connect a fused #16 gauge wire from the “on” position

of the engine control or ignition switch to the heater

terminal. This connection must be waterproof. Use an 8
to 10 amp. fuse with 12 volt end covers and with 24 volt
end covers identified with the marking “24V 120W.” Use
a 4 to 5 amp. fuse with 24 volt end covers identified with
the marking “24V.”
