• 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 a moderate 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 a sound 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.
A WARNING
Tightness test after installation
• Spray a moderate 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 a pipe connection, remake the
joint.
ADJUSTMENT AND CHECKOUT
Electrical connection
A WARNING
• Switch off power supply before making electrical
connections.
A WARNING
• 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 a terminal
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.
