SAFETY INSTRUCTIONS
•
It is recommended to wear hand-gloves while making connection or disconnection of Danfoss’ Multi-FF device.
•
Hold top plate / movable plate on hose lines or on to a surface perpendicular to handle strips, to avoid finger
entrapment during engagement with fixed plate.
•
Once two plates / sub-systems are engaged, remove your hand off the plate and only rotate the handle. Do not put
hand/fingers in between 2 plates.
•
Ensure that fingers are not entrapped in between bottom/fixed plate and handle of the device during operation
•
Ensure absence of pressure inside the Multi-FF before initiatingdisconnection of system or carrying out any
maintenance work.

OPERATING CONDITIONS
This section covers general operating conditions to obtain long life of multiplate coupling without unpredicted failure.
It is advisable to use multi plate coupling under same operation conditions.
The allowed operating temperature lies between -20°C to 100°C. This is operating temperature of multiplate coupling
assembly and subjected to change based on seal material configuration of Coupling half. The permitted storage
temperature lies b10°C and +35°C.
The maximum operating relative air humidity should not exceed 75%. Similarly, it should not exceed 60% for storage.
Dust & vibration free environment will ensure correct functionality of multiplate coupling.
Maximum operating pressure for multiplate coupling is as follow. These are tested at 1:4 times operating pressure and it
is advisable that system pressure for continuous service shall not exceed maximum operating pressure recommended
below.
