10.3.2 Replacing or tightening the hoses
Hose connection on the pressure and/or return line is leaking or hoses are defective. Tighten
the hoses on the control valve.
(Please note! Observe torque of M
A
= 40 Nm!)
NOTE when using mono-couplings:
If you want to change the hoses, you must first dismantle the mono-couplings.
CAUTION (when using the mono-coupling system)!
Take care that the port ‘T’ of the recycling unit is always connected to the port ‘T’
of the mono-coupling.
CAUTION (when using the quick-disconnect coupling system)!
The return hose, which is screwed onto port “T” of the recycling unit, must always
be fitted with a male quick-disconnect coupling.
However the supplying hose line must be fitted with a female quick-disconnect
coupling.
Procedure:
1. Loosen the 2 B screws in the handle sleeve
with quick-disconnect protective sleeves C
(hexagon socket)
2. Remove handle sleeve A and tighten
screwed connection. If necessary, renew
seals.
3. Dismantle hose D and sealing ring E. (This
point is omitted if the hoses are just being
tightened!)
4. Screw the hose with sealing ring back on.
Please ensure that the insulating washer F
is on and correctly assembled.
5. Tighten the hose connection on the control valve. (Please note! Observe the
necessary torque of M
A
= 40 Nm!)
6. Then replace handle sleeve, protective sleeves and screws, tighten (Torque:5 Nm) and
secure it with thread-locking compound (e. g. LOCTITE 243).
