INSTALLATION
Wall Mounting
1. Select a suitable location complying with the gage manufac-
turer's recommendations. The most common location for room
pressure measurement is on the wall next to the door entering
the room at the 5 ft. level. The wall depth must be at least 2-1/2
in. and clear of any obstructions.
Note: Always check for proper clearance before cutting any
holes.
2. Using the mounting plate (A1) as a guide, mark the wall for
the gage opening, local room reference fitting and mounting an-
chors.
3. Cut out the opening and drill the anchor holes with a 3/16 in.
drill and install the wall anchors (A3).
4. Install the gage on the mounting plate using the hardware
provided with the gage. Make sure to square the gage with the
mounting plate ensuring the jack screws contact the three
mounting ears.
5. Push one of the plastic tubing pieces (A5) onto the reference
fitting and onto the appropriate fitting on the back side of the
gage.
Note: For most applications this would be the low port. Cut the
tube to the length required. Tubing should not kink after instal-
lation.

Parts List
A1 – Gage mounting plate
A2 –Wall anchor screws
A3 – Plastic wall anchors
A5 – Plastic tubing
6. Install the remaining piece of plastic tubing onto the uncon-
nected port on the back side of the gage. Connect the other end
of the tubing to the room pressure sensor located in the room
being measured.
Note: The accessory space pressure sensor kit A-465 provides
an ideal solution for remote room sensing.
7. Insert the assembly into the wall taking care to avoid kinking
the tubing. Secure the mounting plate to the wall with screws
(A2).
8. To calibrate the gage equalize the pressures being sensed
(i.e., open the room door and/or shut down the air handler), and
zero the gage.

Panel Mounting
Panel mounting is accomplished following most of the steps
listed for wall mounting. Some of the differences are listed
below:
• Use the appropriate length and type of mounting screws for se-
curing the mounting plate (A1) to the panel.
• If the high and low references are remote from the panel, con-
nect the pressure sensing tubing to the appropriate ports on the
gage.
• If clearance behind the gage is a concern, the side ports on the
gage may be used.
To use the side ports, install the factory supplied plugs on the
back ports and install the barbed fittings supplied with the gage
on the side ports.
Note: Install the barbed fittings on the side ports after the gage
is mounted on the panel.
