3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the installation,
operation and maintenance of the devices.
• local safety regulations - the operator is responsible for observing
these regulations, also with reference to the installation personnel.
Danger - high pressure.
▶ Before loosening the pipes and valves, turn o the pressure and
vent the pipes.
Risk of electric shock.
▶ Before reaching into the device or the equipment, switch o the
power supply and secure to prevent reactivation.
▶ Observe applicable accident prevention and safety regulations
for electrical equipment.
Risk of burns/risk of re if used for a prolonged switch-on time
through hot device surface.
▶ Keep the device away from highly ammable substances and
media and do not touch with bare hands.
Risk of injury due to malfunction of valves with alternating
current (AC).
Sticking core causes coil to overheat, resulting in a malfunction.
▶ Monitor process to ensure function is in perfect working order.
Risk of short-circuit/escape of media through leaking screw
joints.
▶ Ensure seals are seated correctly.
▶ Carefully screw valve and pipelines together.
To prevent injury, ensure that:
▶ Do not make any external modications to the housing of the
device. Ensure that the system cannot be activated unintentionally.
▶ Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶ After an interruption in the power supply or uidic supply, ensure
that the process is restarted in a dened or controlled manner.
▶ Do not put any loads on the body.
▶ The general rules of technology apply to application planning
and operation of the device.

Special instructions for valves circuit function B (NO) with
deaeration connection G1/8 on the coil (CF05/MX62):
The deenergized valve is open. The
medium also ows o via the deaeration
connection on the coil.
Valves of this design are therefore
suitable for relieving compressors only.
4.2 Application conditions
Ambient temperature: max. +55°C
Operating duration: Unless otherwise indicated on the type
label, the solenoid system is suitable for
continuous operation
Important information for functional reliability during continuous operation.
If standstill for a long period at least 1-2 activations per day
are recommended.
Service life: High switching frequency and high pres-
sures reduce the service life

Escaping medium.
When a sticking nut is loosened, medium may escape.
▶ Do not tighten sticking nut any further.
Overheating, risk of re.
Connection of the coil without pre-assembled valve will result in
overheating and destroy the coil.
▶ Connect the coil with pre-assembled valve only.
