Installation - Graco Matrix 312964C Manual

Installation

NOTICE
• Do not over tighten tank level monitor into tank
bung! Over tightening can cause permanent dam-
age and result in inaccurate readings.
• Do not use thread sealant or adhesive! Many of
these products are chemically incompatible with the
PC/ABS plastic.
• Use the Graco-supplied down tube 15U731 only. Do
not replace down tube with any other tube.
1. Remove the bung fitting and screw in the TLM
hand-tight. DO NOT use a wrench to tighten as this
may damage the TLM. Do not use thread lock adhe-
sive as this may damage the TLM.
2. The TLM must be mounted within 2 degrees from
perpendicular to the surface of the fluid. A level that
measures degrees should be used. Place the level
on the top of the pipe fitting on the tank. If outside
the 2 degree specification, the fitting should be
changed.
Graco recommends that the height of the tank fitting
should not exceed 1/2 in. (1.27 cm). The fitting
height can be up to 2 in. (5.08 cm), provided the fit-
ting is within 2 degrees of the surface of the fluid.
Also, the taller the tank, the more critical the 2
degree specification becomes. See F
NOTICE
• The TLM will not operate correctly if tilted more than
2° from the surface of the tank liquid.
• The TLM will not read properly if:
- Fluid in the tank is agitated (i.e. filling a tank
with oil or anti-freeze). Be sure to take all TLM
readings when the fluid in the tank is calm.
- TLM is mounted next to the tank wall or in a cor-
ner.
- If there is any structural bracing or obstruction
between the TLM and the surface of fluid in
tank.
- If the down tube is not the Graco-supplied down
tube.

Do not install the TLM in the tank's fill port. Repeated
removal of the TLM will damage the unit and void the
warranty.
Port (D) is not to be used as a fill hole for oil deliveries.
See F
The tank's breather port might be the only available
location for mounting the TLM. The horizontal 2 in. npt

port (D) can be used to accommodate the breather. The
breather should be mounted in an upright position using
a 90° elbow fitting.
Do not use the horizontal port for routing pressure
relief return tubes. This can result in inaccurate
readings.
