GENERAL SAFETY INSTRUCTIONS
►
This product is not a safety device and may not be used as
such.
►
The product may not function properly as a result of dirt,
wear, damage (for example, by dropping) or improper use.
Therefore, the product should not be used in applications
where a malfunction can cause danger or damage.
►
Check the compatibility of the medium used, temperature
and other operating conditions with the materials and
specifications of the product. It is the responsibility of the
user to select the right product for the application.
►
This product is not intended or approved for medical
applications, food and/or application in gas appliances.
►
Solenoid valves can only be used with clean liquids or gases.
It is recommended to install a filter before the solenoid valve.
►
Never exceed the limits for pressure, temperature or voltage
as indicated on the product and/or in the technical
documentation.
►
The temperature of a solenoid valve coil can rise during
operation; this is normal. Overheating will cause smoke and a
burning smell. In this case, the power supply must
immediately be disconnected.
►
A solenoid valve opens and closes quickly. Improper use can
cause pressure waves (fluid hammer) in the pipes with
possible damage as a consequence.
►
Beware of electric shock when working with electrical
equipment
.

INSTALLATION AND MAINTENANCE
1.1.
Safety instructions before starting
►
It is recommended to install the product in a dry
environment. In moist environments, make sure that no
moisture can penetrate the coil, actuator or connector.
Ensure that the solenoid valve is installed in an area with
adequate ventilation to facilitate heat dissipation. Make sure
the solenoid valve is not in contact with or in the vicinity of
flammable materials. Ensure that the product is protected
from frost. Frost may damage the product and/or block the
moving parts, causing the product to malfunction.
►
Operations may only be performed when the system is not
pressurized, electrically disconnected and cooled down.
►
Turn off the power supply before performing any work on the
solenoid valve to prevent the risk of electrical shock and to
prevent activation of the solenoid valve.
►
The product is only safe when properly installed and operated
by qualified persons. Please read the safety instructions and
technical documentation carefully before installation, use or
servicing. Always observe applicable and generally accepted
safety
Measures.
►
Ensure a safe startup after installation or maintenance.
►
Water hammer is a typical consequence of a high flow rate
and pressure in pipes with small diameters. There are several
solutions to this problem:
►
Reduce the pressure with a pressure reducing
valve before the solenoid valve.
►
Increase the pipe diameter if possible.
►
Dampen the water hammer by using a flexible
hose or buffer before the solenoid valve.
1.2.
Installation
Clean fluids and gases
The solenoid valve can be used in combination with clean liquids or
gases. Make sure that the pipe may contain dirt before installing the
valve. It is recommended to install a filter (500 µm) before the solenoid
valve.
Mounting the valve
Be aware of the direction of flow of the medium when installing the
valve. Solenoid valves with an arrow on the housing must be connected
in the indicated direction. The pipes on both sides of the valve must be
securely fastened. Use a wrench for both valve and pipe while tightening,
to prevent unnecessary stresses in the system. The solenoid valve must
be fixed via the provided connection points. Only exert force at the
designated areas on the body such as the hexagon; never to the coil or
armature. Avoid vibration in the pipes. Use a suitable sealant for
threaded connections of the solenoid valve. Avoid the entry of sealing
material in the valve, this can lead to malfunctioning of the valve.
Position
It is recommended to install the solenoid in vertical position with the coil
facing upwards. This reduces the probability of the collection of debris in
the solenoid valve. When the solenoid valve is mounted at an angle, it is
recommended to deviate maximally 90° from the vertical position.
