Safety Information for Danfoss
Quick Disconnect Couplings
1.0 General Instructions.
1.1 Scope. The scope of this safety bulletin is to warn against
improper selection, use, installation, etc. of Danfoss coupling
products.
1.2 Distribution. A copy of this safety bulletin should be
distributed to all individuals responsible for using and/or
selecting Danfoss coupling products.
1.3 Fail-Safe. Design all systems and equipment for fail-safe
operation such that failure of any component does not result in
personal injury and/or property damage.
1.4 User Responsibility. It is the sole responsibility of the user to
select and determine that the Danfoss product is compatible
with the end use application. The user is responsible for reading
and following this safety bulletin as well as any instructions or
literature on the Danfoss product being used. The user must
provide necessary product warnings for Danfoss couplings
products, used with systems or equipment, to the operators of
the systems or equipment.
1.5 Usage with other Manufacturers’ Products. When
using Danfoss coupling products with other manufacturers’
adapters, hoses, etc., do not exceed the lowest pressure rating of
any of the components being used or rupture may result.
2.6 Connect or Disconnect Under Pressure.
If connection and/or disconnection of couplings under pressure
is a requirement, only use couplings designed for connection/
disconnection under pressure. Failure to utilize this type of
coupling in that application may result in hose whip, expelled
components, high speed fluid discharge, and/or system
damage. Be certain not to confuse the rated operating pressure
with the rated connect/disconnect under pressure.
2.7 Environment. Ensure that Danfoss couplings are compatible
with the surrounding environment. The surrounding
environment may be heat, salt water, moisture, chemicals, and
the like. Failure to protect against an adverse environment may
cause system damage, premature failure, and/or leakage of fluids
which may be flammable, toxic, at extreme temperatures, or
otherwise harmful.
2.8 External Loads. Avoid any external loads such as side loads,
tensile loads, vibration, etc. Failure to do so may result in
accidental disconnection, premature failure, system damage,
and/or leakage of fluids which may be flammable, toxic, at
extreme temperatures, or otherwise harmful.
2.9 Welding & Brazing. Extreme heating of plated products above
+450°F (+232°C) such as welding, brazing, baking, etc., where the
plating is burned off, may result in the release of deadly gases.
3.0 Installation of Danfoss Couplings.
2.0 Selection of Danfoss Couplings.
2.1 Pressure. Ensure that the maximum operating pressure of the
system or equipment does not exceed the rated operating
pressure of the Danfoss coupling product or rupture may result.
2.2 Fluid Compatibility. Verify that all components (seals, metals,
etc.) are compatible with the fluid being conveyed. Failure to do
so may result in high speed fluid discharge and/or leakage of
fluids which may be flammable, toxic, at extreme temperatures,
or otherwise harmful.
2.3 Temperature. Ensure that the maximum operating
temperature of the system or equipment does not exceed the
rated operating temperature of the Danfoss coupling product
(including seals) or rupture may result.
2.4 Coupling Size. Use properly sized couplings such that there is
not a large pressure drop across them thus avoiding system
damage due to excessive heat generation or failure of internal
components.
2.5 Sleeve Lock. Use sleeve locks or threaded couplings where
there is the possibility of accidental disconnection. Failure to
utilize sleeve locks or threaded couplings in these applications
may result in hose whip, expelled components, high speed fluid
discharge, system damage, or leakage of fluids which may be
flammable, toxic, at extreme temperatures, or otherwise harmful.

3.1 Inspection of Product. Prior to installation, ensure that the
Danfoss product meets all of the requirements of the system
and/or equipment it is to be used on. Ensure you have the
correct part number, function test the coupling by connecting it
with a mating half. The function test should result in smooth,
non-binding operation or premature failure may result.
3.2 Cleanliness. Use end caps and plugs to reduce the risk of
system contamination or damage to critical sealing surfaces.
Failure to do so may result in leakage of fluids which may be
flammable, toxic, at extreme temperatures, or otherwise harmful.
Caps and plugs are not a secondary seal unless explicitly noted.
3.3 Location. Place Danfoss couplings in a safe location such as not
to expose the user to personal injury (slippage, tripping, falling,
etc.) during installation, connection, disconnection and
maintenance.
4.0 Product Maintenance. A maintenance schedule should be
put in place to ensure that Danfoss couplings are functioning
properly. Danfoss is not responsible for product failures resulting
from modification or improper maintenance.
4.1 Inspection. Visually inspect to ensure that there is no leakage,
cracked components, corrosion build-up, contamination
build-up, wear, etc. If any abnormality is encountered, the
coupling should be replaced immediately.
