Operation
Pressure Relief Procedure
1. Close the air regulator by turning counterclockwise as
far as possible.
2. Disconnect the air line quick coupler to relieve air
pressure.
3. Open the dispensing valve, if used.
4. 4. Open the fluid drain valve to relieve all fluid
pressure, having a container ready to catch the
drainage.
Flush the Pump Before First Use
The pump was tested in water. If water could contaminate
the fluid you are pumping, flush the pump thoroughly with
a compatible solvent. Follow the steps under Starting and
Adjusting the Pump.
Starting and Adjusting the Pump
All Systems
1. Be sure the pump is properly grounded and bonded.
Read FIRE OR EXPLOSION HAZARD on page 3.
2. Check all fittings to be sure they are tight. Use a
compatible liquid thread sealant on all male threads.
Tighten the fluid inlet and outlet fittings snugly. Do not
overtighten the fittings into the pump.
3. For the first startup: Connect the fluid inlet hose to
the pump and place the other end of the hose in a two
quart container of oil. Start the pump following Steps
1, 3 and 4 in either of the following startup
procedures. When the container is empty, shut off the
air to the pump and reconnect the hose to the suction
line. This procedure wets the pump internal parts to
ensure maximum suction.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air
regulator. Remove the suction tube from the solvent and
place it in the fluid to be pumped.
WARNING
PRESSURIZED EQUIPMENT HAZARD
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious injury
from pressurized fluid, accidental spray from the gun or
splashing fluid, follow this procedure whenever you
• Are instructed to relieve pressure
• Stop pumping
• Check, clean, or service any system equipment
• Install or clean fluid nozzles
WARNING
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause
serious injury or death if splashed in the eyes
or on the skin, inhaled, or swallowed. Do not
lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the Pressure
Relief Procedure at left before lifting the pump.
