Operating Manual For
GEWAS 191 and GEWAS 191A
Scope of supply:
1 x control device GEWAS 191 or GEWAS 191A
1 x water sensor GWF-1S
1 x solenoid GMV 191 12VDC
1 x bushing
1 x sealing ring
Specification:
Voltage supply : 220/240V 50/60Hz (control device)
Power rating: approx. 3 Watt
max. switching current: 16A ohmic load (for GEWAS 191A only)
Solenoid: max. working pressure: 6bar servo controlled (pressure difference infeed/outfeed >0,5 bar)
Dimensions: control device: 126 x 79 x 54 (L x W x H)
solenoid: 82 x 52 x 41
EMC: The GEWAS 191 and GEWAS 191A correspond to the essential protection ratings established in the
Regulations of the Council for the Approximation of Legislation for the member countries regarding
electromagnetic compatibility (89/336/EWG)
Installation and commissioning:
1. Installation of solenoid
- Lock water feed lines.
- Screw bushing onto the solenoid by means of a left-hand turn.
- Insert sealing ring.
- Connect solenoid and bushing to the water feed by means of a right-hand turn. The solenoid
will automatically be drawn towards the sealing.
- Check for leakage by opening the water feed.
=> in case of leakage repeat the process described above but change position of bushing on
the solenoid slightly.
- Screw water connection tube to the outlet side of the solenoid (use existing sealing ring or
make sure that tube itself is properly sealed! ).
If the installation has been carried out correcly the bushing can be tightend by hand. In case of
leakage check if sealing has been inserted and if all sealing surfaces are clean; also check if
the installation has been carried out correctly, e.g. if the bushing (both right-hand and left-hand
thread covering one half) is positioned correctly on the solenoid (p.r.t. installation of the
solenoid point 2). If necessary repeat installation process. Tightening by force (e.g. by means of
a pipe wrench) in case of a leakage at the solenoid will only damage the right- and left-hand
thread in the bushing but will do nothing to remedy the fault cause.
Advice for commissioning:
The solenoid will not be opened unless it has been connected to the activated control device.

2. Installation of control device and water sensor
- Make it a rule to read the operating and maintenance advises before starting-up the device.
- Place water sensor at desired position and fix it, if necessary.
- Connect water sensor and solenoid to the control device.
- Open water feed line unless you have already done so.
- Plug in control device into a socket outlet with earthing contact.
=> Device is now active, the solenoid is open.
- Check water connection for leakage.
- Connect device which is to be switched off in case of alarm to the socket outlet with earthing contact of the control device.
! Well done, your GEWAS device is now ready for use !
