7. Connect the exhaust line (l) for restricted exhaust if necessary.

Restricted exhaust
The regulators and filter regulators provide an option for relieving exhaust via a
connected exhaust line. An M5 thread (o) is located in the spring cover for this
purpose. The thread on the F&B version is located in the cover for the adjusting
screw (= cover m).
Semi-automatic and manual condensate drain
The condensate could cause damage to the compressed air system!
In a semi-automatic condensate drain, the condensate is drained only when a
pressure differential of approx. 1 bar is present in the reservoir. Over long periods
of operation, the condensate can exceed maximum capacity and get into the
compressed air system. This could damage the compressed air system.
O Make sure that a pressure differential of approx. 1 bar is present in the
reservoir at regular intervals (e.g. by temporarily switching off the system,
see "Switching off the system").
O Do not allow the condensate to enter the environment in an uncontrolled
manner (e.g. connect an exhaust line).

Semi-automatic condensate drain
The semi-automatic condensate drain remains closed at a constant operating
pressure. The condensate drain opens at a pressure differential of approx. 1 bar.
The drain closes as soon as the operating pressure returns to a steady level.
Manual condensate drain
The condensate can be drained manually.
O Mount a drip container below the drain opening and press from below against the

Service and Repairs

Cleaning and servicing
O Seal all openings with suitable protective caps to prevent detergents from
penetrating the system.
Changing the filter element:
System is operating under pressure!
Opening the system when it is under pressure can result in personal injury and
cause damage to the MH1 maintenance unit/device.
O Ensure that the system is pressure-free before opening the reservoir.
Filters become contaminated with use and must be changed regularly, at the latest
after one year. This, however, is only a recommendation, since the interval depends
on the quality of the compressed air and the amount of air throughput.
To place your order, use the material numbers listed below. You can find the
addresses for AVENTICS national representatives at www.aventics.com/contact.

Changing the filter element:
1. Turn reservoir counterclockwise and remove (a, b).
2. Turn filter piece and remove (c, d).
3. Remove upper swirl cap and change filter insert (e).
4. Reassemble the individual parts.
5. Rotate new filter insert into assembly (f) and tighten slightly by hand (g).
6. Screw in reservoir by turning it clockwise as far as it will go (h, i).

7 Decommissioning, Disassembly, Exchange
Danger of injury if disassembled under pressure!
Assembling when under pressure can lead to injuries and damage to the product
or system components.
O Make sure that the relevant system part is not under pressure before you
disassemble the product or exchange parts.
O Protect the system against being switched on.
8 Disposal
Scrap the device and condensate in accordance with local regulations.
9 Extension and Conversion
Danger of injury if assembled under pressure!
Assembling when under pressure can lead to injuries and damage to the product
or system components.
O Make sure that the relevant system part is not under pressure before
extending or converting the product.
O Protect the system against being switched on.
Changing the pressure gauge
5-II
1. Rotate old pressure gauge out of pressure gauge thread.
2. Remove remnants of the old sealing material.
3. Mount the new pressure gauge as described in "Mounting the pressure gauge".
3 5 Changing the flow direction
When delivered, the flow direction is from left (
1. Make sure the relevant system part is not under pressure.
2. Turn the product while taking the mounting orientation into account,
see chapter "Technical Data".
