Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before clean-
ing, checking, or servicing the equipment.
1. Press the enable/disable key on the ADM
disable the EFR/HFR, and verify it is inactive.
2. Relieve pressure and shut off the supply systems.
See your appropriate supply system manual.
3. Turn the PRESSURE RELIEF/DISPENSE valves to
PRESSURE RELIEF/CIRCULATION. Route the fluid
to grounded waste containers or supply tanks.
Ensure gauges read 0.
4. For models with a dispense valve with a safety lock,
engage the dispense valve safety lock.

Flushing

To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
Hot solvent may ignite. To avoid fire and explosion:
• Flush equipment only in a well-ventilated area
• Ensure main power is off and the heater is cool
before flushing
• Do not turn on heater until fluid lines are clear of
solvent
• Flush before changing colors, before fluid can dry
in the equipment, at the end of the day, before
storing, and before repairing equipment.

• Flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.

Maintenance

Grease Cup Maintenance

NOTE: If the quick lube system is installed on the
Z-Pump elite series, use one of the following operation
manuals for instructions. 313997, 3A1961 or 3A6165.
Grease Cup Maintenance
NOTE: For pumps with grease fittings.
Frequency of greasing intervals is dependent on
material being pumped. As a basic schedule, lubricate
pump with grease after 250 gallons of material (five of
fifty five gallon drums) has been passed through the
pump.
If the grease has become hardened, remove the
materials or grease, and shorten the intervals between
to
greasing the pump.
If the grease remains clear and free of material, intervals
between greasing the pump can be increased.
To Grease the Pump
1. Remove the M5 hex socket plug (D) to permit
grease to circulate through the throat cartridge
(119) correctly.
2. Attach grease gun to the grease fitting (C). Pump
new grease into the pump until fresh grease is
observed from grease relief hole (E).
3. Replace and re-tighten the M5 hex socket plug (D).
