APPLICATION
The C4065/C6065 differential air pressure switch for forced
flue combustion type burner system functions as a
(combustion) airflow supervision with a safe start interlock.
The C4065/C6065 differential pressure switch is designed to
be used on air or combustion products.
The C6065AH and C6065FH with enhanced accuracy are
according the requirements of high efficiency appliances.
Note:

Application notes
Considerations should be given to the following guidelines in
applying the C6065 air pressure switch:
Pco
Time
Meaning of point Pa, Pb, Pco is the following:
Pa: Maximum pressure differential with a cold
appliance.
Pb: Maximum pressure differential in a normal working
appliance.
Pco: CO point, this means that the appliance starts to
produce more CO than allowed.

MOUNTING POSITION
Horizontal mounting
When the air pressure switch is to be mounted with the
diaphragm horizontal, it is critical to state it.
The weight of the membrane will more up or down the setting
point, compared with the vertical mounting.
See fig. 4. for the shift.
When the product is used horizontally, in the particular case
when the micro switch is in upper position, the setting
tolerances are increased as described by table 3.

INSTALLATION
Provide condensate drainage by gradually sloping tubing
towards the exhaust pressure inlet (fig. 7.)
If suitable drainage is not possible then a drip leg should
be installed
Since combustion products are normally at a high
temperature, special consideration to piping length and
mounting location should be given so that the pressure port
surroundings are not subjected to ambient temperature in
excess of 90 _C.
WARNING
Products of combustion generally contain a large
quantity of vapour and generate condensation within
the device as it cools.
Condensate in the tubing or within the body of the
C6065 can cause pressure control point offset.
Condensate can also damage metal parts of the
device, making replacement necessary.
When used as primary safety control, the C6065 must
be part of a safe start circuit.

terminal (N.C.)
Common terminal
Location
To prevent condensate damage, the following procedure
should be observed when mounting the C6065:
Mount C6065 with the pressure connections at the bottom
so that condensate does not penetrate into the device.

QUALITY ASSURANCE
Assembly process are guided by work instructions. At the end
of assembly phase, all differential pressure switches are
leakage and performance tested/adjusted.
Shipping inspection is performed by employees of production
department who are responsible for quality, using their own
equipments.
All inspections (incoming and assembly) are performed by
trained personel and according inspection procedures.
