APPLICATION
The gas pressure switch C6097Ais used to detect the
pressure of city gas, natural gas,
LP gas or air etc.
When the gas pressure changes, the diaphragm of the
pressure receiving part detects it and operates the (SPOT)
switch to ON/OFF control of the external electrical circuit.
These switches are widely used to detect the upper limit or
lower limit pressure of gas or air to be supplied to agas
burner, or to detect the clogging of the interlock filter of a
burner blower.

•Disconnect power supply to the pressure switch
before beginning the installation to prevent
electrical shock and damage to the equipment.
•Turn off gas supply before installation.
Mounting and orientation
In vertical, or horizontal plane with the setting dial facing
upwards. Make sure that dirt or humidity does not get into the
connection open for ventilation
(G in Figure. 1.).

•Do not remove the seal over the pressure inlets,
until ready to connect piping.
Connecting positive pressure inlet (stand alone)
1. Take care that dirt does not enter the pressure switch
during handling.
2. Remove the dust seal from the positive pressure inlet.
3. Apply amoderate amount of good quality compound to
the pipe for fitting only, leaving the end thread bare,
PTFE tape tape may
be used as an alternative.
4. Use asound tapper fitting with thread according to
ISO 7-1 (8S21 ,
DIN 2999) or new, properly reamed
pipe, free from swarf.
5. Screw the pressure switch onto the pipe, using the
wrench boss incorporated
in the housing.
6. Complete the electrical connections as instructed in the
Electrical connections section.
Connecting positive pressure inlet (flange mounted)
1. Take care that dirt does not enter the pressure switch
during handling.
2. Remove the dust seal from the positive pressure inlet.
3. Place the a-ring. If necessary grease it slightly to keep
it in place.
4. Mount the pressure switch on the valve body and screw
it tightly with the two M4 mounting screws.
5. Complete the electrical connections as instructed in the
Electrical connections section.
AWARNING
Tightness test after installation
•Spray amoderate amount of of good quality leak
detection spray
on all pipe connections.
•Start the application and check for bubbles. If a
leak
is detected in apipe connection, remake the
joint.
ADJUSTMENT AND CHECKOUT
Electrical connection
AWARNING
•Switch off power supply before making electrical
connections.
AWARNING
•The adjustment and checkout has to be carried out
by qualified personnel only.
•Terminals are accessible,
no protection against
electrical shock.
•Take care that the wiring
is in accordance with local
regulations.
Use lead wire that can withstand 105
QC ambient.
The electrical ON/OFF operator
is provided with aterminal
block for electrical connections.
Wiring
Follow the instructions supplied by the appliance
manufacturer. Refer to Figure
2. and 3. Connection diagram
C6097A.
Pressure set point adjustment
(tolerance ± 15 % over total scale)
NOTE: The knob readings are approximations of the actual
settings.
1. Remove the cover of the pressure switch.
2. Turn the dial clockwise to increase or
counter-clockwise to decrease the pressure set point.
3. Replace the cover.
3
EN1R-91729907R1-NE

Accurate pressure set point adjustment
(stand alone only)
(tolerance <3% over total scale)
1. Remove the screw from the test nipple inlet.
2. Connect the tube of the pressure measurement device
to the nipple (Fig.
1. F).
3. Remove the cover of the pressure switch.
4. Slowly release pressure of the main gas supply line until
the desired value
is reached.
5. Turn dial slowly until contact 1-3 opens and contact
2-3 closes.
6. Replace the cover.
7. Disconnect the pressure measurement device and
replace the screw.
Checkout
Checking cut-off pressure
After the installation is completed, continue with the following
procedures:
1. Slowly close manual main valve with the burner in
operation. Shut down should occur when the pressure
drops below the set point and the alarm
(if connected)
should
be energized.
2. Re open the manual main valve. The pressure should
rise and exceed the set point value, the burner should
start
up and the alarm turn off after the reset button is
depressed.
