Operation - Aventics HF04 Montageanleitung

5 AVENTICS | HF04/LP04 | R412009744–BDL–001–AB
Tools required: Screwdriver PZ0, Ø max. 3 mm,
e.g. bit 855/00 size 0x50 mm, code 055805 from WERA
Any mounting orientation may be used.
The pressure regulator can only be mounted on the
subbase with bore holes from version 05.08.
Older subbases have no bore holes. If necessary, please
contact your sales service.
Use only subbases with bore holes (6).
O
1. Check that the pressure regulator matches your order
using the material number printed on the housing.
2. Remove two valves in adjacent valve positions by
loosening the screws (7) and pulling them upwards off
the subbase (5).
3. Mount the pressure regulator as follows:
– HF04: On a double subbase or half-and-half on two
double subbases
– LP04: On two single subbases
4. Check the correct seating of the molded seals.
5. Tighten the mounting screws (4) crosswise
(see figure 1 ). Tightening torque: 0.2–0.3 Nm,
max. speed: 500 rpm
6. Mount the valve to be controlled at valve position 1 (1) of
the pressure regulator.
6 Commissioning
Let the pressure regulator acclimatize for several hours
O
before commissioning, otherwise water may condense
in the housing.
Setting the pressure regulator
1. Pull the blanking plug (9) out of push-in fitting (8) and
connect the preassembled pressure gauge with
compressed air hose 4 to the push-in fitting.
2. Slowly pressurize the system to the stipulated working
pressure.
3. Pull the safety cap (12) off the pressure regulator.
4. Loosen the lock nut (10) while counter-holding the
adjustment screw (11).
5. Set the secondary pressure at the adjustment screw.
6. Tighten the lock nut (10) while counter-holding the
adjustment screw (11).
7. Fit the safety cap (12) again.
The pressure is now set for operation.

Operation

Pressure regulators are not gas-tight. Leakages of
10 ml/min can occur even when new.
Malfunction with unstable supply pressure!
The function of the pressure regulator is no longer
assured if the supply pressure drops below the pressure
to be regulated.
Ensure that the supply pressure does not drop below
O
the regulated pressure.
8 Service and maintenance
NOTICE
Damage to the surface caused by solvents and
aggressive detergents!
The seals on the pressure regulator may age faster
under aggressive ambient conditions.
Never use solvents or aggressive detergents.

CAUTION
Clean the pressure regulator at regular intervals only
O
using a slightly moist cloth. Only use water to do this
and, if necessary, a mild detergent.
The pressure regulator is maintenance-free.
9 Disassembly
Danger of burns caused by hot surfaces!
Touching the device during operating may cause burns.
Let the device cool off before disassembling it.
O
Do not touch the device during operation.
O
Danger of injury if disassembled under pressure!
Injuries and damage to the device or system components
may occur if the pressure is not switched off before
beginning disassembly.
Make sure that the relevant system part is not under
O
pressure before you disassemble the product.
1. Remove the valve by loosening the screws (7) and
pulling it upwards off the pressure regulator.
2. Remove the pressure regulator by loosening the screws
(4) and pulling it upwards off the subbase.
