The prerequisites to be observed when checking and
adjusting DHK/UI can be found in the test instruc-
tions for DHK/UI in ESI[tronic] 2.0. These test in-
structions do not form part of the scope of delivery.
ESI[tronic] 2.0 can not be installed on the EPS 205.

Procedure:
1. Clean the DHK/UI (see Sec. 7.3 ).
2. Fit the injection chamber on the DHK/UI.
i
A UI can only be connected using the UI connection
adapter (special accessory).
3. Attach the DHK/UI (Fig. 38, item 3) to the clamp
(Fig. 3, item 3).
!
To avoid twisting and premature wear, do not con-
nect the high-pressure hose directly to the DHK/UI.
4. Connect the high-pressure hose with the connection
adapter (Fig. 38, item 4, 5) to the DHK/UI.
!
The connection adapter must be tightened to a
torque of between 25 Nm and 30 Nm. If the con-
nection between the connection adapter and the
DHK/UI is leaking, the screw connection is not to
be re-tightened. In the event of a leak, unfasten the
1
connection again, clean the sealing surface and re-
connect the connection adapter applying the correct
tightening torque.
5. Connect the hose 1 680 712 362 to the quick-release
coupling of the injection chamber (Fig. 38, item 2)
and to the "DHK/UI flushing connection and test con-
nection" (Fig. 38, item 1).
6. Close the guard.
7. Perform the test.
