WARNING
Pressure Relief Procedure
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, or injury
from moving parts, fire, explosion, or electric
shock, always follow this procedure when shutting
off the system, when checking or servicing any part
of the spray system, and whenever you stop opera-
tion.
1. Turn off the fluid supply to the meter.
2. Shut off all electrical power to the fluid system
or air system.
3. Follow the Pressure Relief Procedure for your
fluid system dispensing device.
CAUTION
The flow meter rotor can be damaged if it rotates at
too high a speed. To avoid high speed rotation,
open the fluid valve gradually. Do not over-speed
the rotor with air or solvent. To prolong meter life,
Do not use the meter above the maximum flow rate
of 1000 cc/min. (34 oz/min.).
Recommended Usage
The flow meter can be used with fluids that are 0 to
50 C (0 to 122 F).
Use the flow meter with the filter provided, as abra-
sive fluids can cause problems with the rotor.
