CAUTION
Graco recommends using PTFE tape on hose threads
prior to installing the Matrix meter. PTFE tape should
be after the leading thread and clockwise (same direc-
tion as meter installs on hose fitting). Caution should
be taken not to get tape into the meter during installa-
tion as this can cause the meter to malfunction.
Should the tape be the cause of the malfunction,
Graco warranty will be denied.
2. Apply PTFE tape to the male threads of the hose fit-
ting (P). See caution above. Leave a minimum of
two engaged threads bare to maintain grounding
continuity.

Pressurizing the System

pump to pressurize the system. See the Operation
section, page 14, for proper operation of meter.
2. To ensure dispensing accuracy, purge all air from
the fluid lines and dispense valve before using it.
3. Set the system flow to the desired flow rate, which is
typically 1.5-gpm. Do not exceed a 5-gpm flow rate.
