Product Information
Volume Flow Controller Type RN
Installation, Operation, Maintenance
Product Application
The volume flow controllers type RN are designed for use
in ventilation and air conditioning systems. Only suitably
painted volume flow controllers should be installed in
systems designed to handle aggressive exhaust air, after
thorough testing has been completed.
Safety Measures
Install professionally and support with secure hanging
brackets.
Packaging, Delivery and Storage
The volume flow controllers are packed in disposable
container.
• Check goods immediately after delivery to ensure that
they are complete and have not been damaged during
transportation. Inform the carrier and TROX immediately
if the delivery is incomplete or damaged.
• Do not expose the controllers directly to the elements
even when packed. Protect from damp, effects of direct
sunlight and dirt.
• Store between –10 ºC and +50 ºC ambient temperature.
• Do not remove packing until just before installation.
Installation and Connection Method
• Choose location so that the scales on the controllers are
accessible.
• The desired volume flow can be read and, if necessary,
set, at an external scale.
• Controller operation not dependent on gravity.
• Ensure air flow is in the direction of the arrow on the label.
• Do not locate controller before bends, near dampers or
other obstructions.
• When conncetion to the main duct, ensure that the length
of the straight branch duct is 1.5 D, otherwise a perforated
plate must be installed as shown.
• For extract air operation, direct connection to the main
duct without a perforated plate is possible.
• Free inlet to controller on extract air application cannot
be used. Fit minimum inlet duct of length 1.5 D, with
suitable fairing to reduce inlet pressure drop.
Duct Connection
The controller spigot diameters are suitable for circular
ducting to DIN EN 1506 and DIN EN 13180 or flange
mounted according to DIN EN 12220 (not by RNS).
The controller should not be drilled under any
circumstances!
• Check connection ducts for debris before installing the
controllers.
• Seal duct connections to controller with approved sealants.
• Heat shrink sleeves ar only to be applied by skilled
operator.
