10 Installation
DANGER
Risk of electric shock
▶There is a danger of injury or death (if
operating voltage is higher than safe
extra low voltage)!
●Before performing any work on the
GEMÜ product, switch off power and
protect circuit from being switched on
again.
NOTICE
ATEX version
▶Please observe the relevant EX regulations, in particular
EN 60079-14 and EN 50281-1-12, during installation and
maintenance .
Prior to installation:
1. Check the suitability of the pilot solenoid valve prior to
the installation!
See chapter "Technical data".
10.1 Installation
WARNING
The equipment is subject to pressure!
▶Risk of severe injury or death.
●Depressurize the plant.
●Completely drain the plant.
Installation location:
CAUTION
●Do not apply external force to the pilot solenoid valve.
•Installation position: Optional.
•Manual override and electrical plug must be accessible.
•Direction of the control medium:
from "P" to "A".
Installation:
•Installation work must only be performed by trained person-
nel.
•Use appropriate protective gear as specified in plant oper-
ator's guidelines.
1. Ensure the suitability of the valve for each respective use.
The valve must be appropriate for the piping system oper-
ating conditions (medium, medium concentration, temper-
ature and pressure) and the prevailing ambient conditions.
Check the technical data of the valve and the materials.
2. Shut off plant or plant component.
3. Secure against recommissioning.
4. Depressurize the plant or plant component.
5. Completely drain the plant or plant component and allow it
to cool down until the temperature is below the media va-
porization temperature and cannot cause scalding.
6. If necessary, correctly decontaminate, rinse and ventilate
the plant or plant component.
7. Carefully remove the caps from the female threads.
10.1.1 Installation - GEMÜ 0326

6. Connect and seal the pressure inlet tubing to connection
"P" 2 (G 1/4).
7. If applicable, connect and seal the exhaust tubing to con-
nection "R" 5 (M5) or mount a silencer.
8. Connect and seal the outlet tubing to connection 4 (G
1/4).
9. Close connections not used with blanking plates 7.
NOTICE
Important:
▶The holes 8 in the aluminium distributor rail must corres-
pond to the holes in the blanking plate.
10. Close the open connection opposite "P" 2 with supplied
sealing plug 3 and gasket 9.
11. All threads must be sealed gas tight.
After the installation:
•Re-attach or reactivate all safety and protective devices.
11 Electrical connection
DANGER
Risk of electric shock
▶Risk of injury or death (if operating
voltage is higher than safe extra low
voltage).
▶Electric shock can cause severe burns
and fatal injury.
●Work on electrical connections only by
qualified trained personnel.
●Disconnect the cable from the power
supply before making the electrical
connection.
●Connect the protective earth con-
ductor.
CAUTION
●Power supply varies dependent on the design (see
product label).
●Do not bridge terminals!
Required for electrical connection:
•Crosshead screwdriver
•Small flat screw driver
The following note only applies to the ATEX version:
NOTICE
▶Every valve solenoid must have a fuse appropriate for its
rated current (max. 3 times rated current in accordance
with DIN 41571 or IEC 60127-2-1) or a motor protection
switch with short circuit and thermal instantaneous trip
(setting to rated current) connected upstream as protec-
tion against short circuits. This fuse may be located in the
corresponding power supply unit or must be connected
separately upstream. The fuse rated voltage must be
equal to or greater than the specified nominal voltage of
the solenoid. The breaking capacity of the fuse unit must
be equal to or greater than the maximum short-circuit cur-
rent occurring at the site of installation (usually 1500 A).

12 Commissioning
CAUTION
Protect against leakage!
●Check the tightness of the media con-
nections prior to commissioning!
●Provide precautionary measures
against exceeding the maximum per-
mitted pressures caused by pressure
surges.
Prior to cleaning or commissioning the plant:
1. Check the tightness and the function of the pilot solenoid
valves.
2. If the plant is new and after repairs blow out the piping
system with a fully opened pilot solenoid valve (to remove
any harmful foreign matter).
Cleaning:
•The plant operator is responsible for selecting the cleaning
material and performing the procedure.

▶Solenoid coil heats up during opera-
tion.
●Allow the solenoid coil and piping to
cool down before servicing work.
CAUTION
●Servicing and maintenance work must only be performed
by trained personnel.
●GEMÜ shall assume no liability whatsoever for damage
caused by improper handling or third-party actions.
●In case of doubt, contact GEMÜ prior to commissioning.
