Instructions:

Step 1. Mix:
• Empty one bag into five-gallon bucket and half fill with
water.¹
• Stir for one minute.
• Fill remainder of bucket with water.
• Stir for one minute.
• Let mix stand for at least 10 minutes.


Step 2. Prime Pump²:
(determine situation that best describes your pump)
• If the pump has a priming port (CAPS), pour into primer
port just ahead of ready-mix.


If primed through the hopper:
For vertical intake ports (gate or rock valve):
• Fill water in hopper high enough for intake parts to charge
as pump cycles.
• Pour the mixed Prime-A-Pac into hopper so the prime is
charged in the system ahead of the ready-mix
For horizontal intake ports (ball or flapper valve):
• Fill water in hopper as necessary in order to allow the port
or ports to charge as pump cycles.
• Pour the mixed Prime-A-Pac directly into intake port just
ahead of the ready-mix.


If primed directly in the hopper:
• Pour at least 5 gallons of water into hopper.
• Pour one bag of Prime-A-Pac primer into hopper and cycle
pump in reverse for 15 to 20 strokes.
• Let stand at least 10 minutes prior to priming system.
• Charge prime into system ahead of ready-mix.


How much to use?
Normally, one bag (2 pounds) for each 100 feet of 5”
system.³


Best results:
Pre-mix in a 5-gallon pail the night before.

¹ Prime-A-Pac provides lubrication for pipe and hose. The responsibility to provide a safe workplace remains with the user. Each user should consider the health
hazards and safety information contained herein as a guide and should take any pre-caution necessary to ensure a safe work environment.
² More water and primer may be needed in cases where the hopper is extraordinarily large or the intake valve is placed high up on the hopper. In all cases,
primer should be completely charged into system ahead of ready-mix.
³ Horizontal pumping jobs may require more priming agent. A sponge may be placed ahead of the mixture to insure that system interior is completely coated.
