Attention!
Equipment will be damaged if the end
connections are undersized.
Make sure that the connections are
strong and rigid enough to support the
weight of the equipment and to
withstand the forces that occur during
operation.
Consider space required for servicing the
equipment and/or exchanging components and
observe the necessary withdrawal distance to
remove the cover. For more information on the
required withdrawal distances see section
"
Dimensions and weights
" on page 31.
Some applications require that the
equipment is fitted with an air-balance
pipe: float traps for compressed air line
drainage and equipment installed in plants
where condensate is lifted upstream of the
equipment.
In this case connect the air balance pipe
to the bore on top of the cover.
Make sure that the pipe system of the plant is
clean.
Make sure that the equipment is free from
foreign matter.
Attention!
Malfunctions may occur if the equipment is
installed incorrectly.
The equipment must be installed with
the inlet end at the top and with the
float arm in a horizontal plane so that
it rises and falls vertically.
Mount the equipment in the desired installation
position.
Make sure that the pipes meet the following
requirements:
The layout of the pipelines must prevent the
formation of water pockets.
The pipeline must have a gradient so that the
condensate is free to fall towards the equipment
The cross section of the air balance pipe must
be at least DN 8 (¼ ") .
If the equipment is fitted with control unit
SIMPLEX, an air balance pipe must be
connected to the vent hole for the hand-vent
valve. The balance line must have a ⅜ ” BSP
end connection.
If one or more of the above mentioned
requirements cannot be met, please contact our
Technical Service or authorized agency in your
country.
Connect the end connections of the equipment
properly to the pipes.
If necessary, connect the air balance pipe to the
equipment as shown in the following drawing.
Make sure that the equipment is safely mounted
and that all connections are made correctly.
Mounting the measuring electrode
You can attach one or two measuring electrodes
(14) of the following type:
To detect banking-up of condensate: NRG 16-
19 or NRG 16-27 installed on top of the body
To detect loss of water seal: NRG16–19 or
NRG16–27 installed at the side of the body
The following tool is required for installation work:
Combination spanner to DIN 3113 form B:
⅜ ” BSP connection: A. F. 17
NRG 16-19: A. F. 22
NRG 16-27 (new): A. F. 27
NRG 16-27 (old): A. F. 32
