Operation – Preparing the Pump for Each Use
17
If the pump has been used previously, it must be prepared BEFORE EACH SUBSEQUENT USE.
WARNING
Read instructions below carefully for inspecting and preparing the pump.
Damaged or clogged equipment could result in leaks or uncontrolled spray.
Leaks could result in injury to the operator or bystanders from chemical exposure, or cause
damage to the environment.
Important safety rules:
•
Power off.
Make sure all power is OFF before cleaning, inspecting, or servicing the pump.
•
Guards/shields.
Make sure all guards and shields are replaced after servicing the pump.
•
Replacement parts.
If a part needs replacement, only use parts that meet the manufacturer’s
specifications. Replacement parts that do not meet specifications may result in a safety
hazard or poor operation of the pump.
1. Ensure clean
system
Ensure the pump has been thoroughly flushed and drained of all
residual chemicals from prior uses.
2. Inspect &
repair
Inspect and test the pump system thoroughly
:
a)
Inspect hoses/lines for exposed mesh and holes. Replace all worn
or damaged hoses/lines.
b)
Inspect fittings for cracks and leaks. Replace all damaged fittings
with original NorthStar parts.
c)
Partially fill system with plain water and spray to test for leaks.
Repair as needed.
IMPORTANT: After any repair work has been done, ALWAYS test for
leaks with water one final time before using.
Be certain the pump materials will be compatible with the chemical being pumped. NorthStar pumps
are intended for intermittent or continuous duty when the proper operating criteria are met. If unsure of
the chemical compatibility with the NorthStar pump components or the motor’s intended design, please
call NorthStar Product Support at 1-800-270-0810 for assistance.
CAUTION
DO NOT
operate the pump at pressures which cause the motor to exceed the amperes rating
indicated on the name plate.
Improper adjustment of the pressure switch setting may cause severe overload or premature
failure. Failures due to improper adjustment of the pressure switch setting will not be covered
under the warranty.
Note: A reserve, clean container capable of holding at least the volume of the entire pump system
should be kept for use when the pump system needs to be emptied temporarily for repairs. It is
advisable to purchase a reserve tank suitable for chemical storage from Northern Tool and
Equipment for use in these circumstances. The container should be properly labeled as to its
contents if it is used.
