Haier 309463N User Manual

1.

Connect the suction kit (K) to the pump's fluid inlet, 
and place the tube into the fluid supply. 

2.

Close the pump air regulator (D). 

3.

Open the pump's bleed-type master air valve (B). 

4.

Hold a metal part of the gun (T) firmly to the side of 
a grounded metal pail and hold the trigger open. 

5.

Slowly open the air regulator (D) until the pump 
starts. 

6.

Cycle the pump slowly until all air is pushed out and 
the pump and hoses are fully primed. 

7.

Release the gun trigger and lock the trigger safety 
latch. The pump should stall against pressure.

8.

If the pump fails to prime properly, open the drain 
valve (G). Use the drain valve as a priming valve 
until fluid flows from the valve. Close the drain valve 
when all air is eliminated.

9.

With the pump and lines primed, and with adequate 
air pressure and volume supplied, the pump will 
start and stop as you open and close the gun. In a 
circulating system, the pump will speed up or slow 
down on demand, until the air supply is shut off.

10. Use the air regulator to control the pump speed and 

the fluid pressure. Always use the lowest air pres-
sure necessary to get the desired results. Higher 
pressures cause premature tip and pump wear.

For a brief shutdown, relieve the pressure, page 12. 
Stop the pump at the bottom of its stroke to prevent fluid 
from drying on the exposed displacement rod and dam-
aging the throat packings. 

For a longer shutdown, or overnight, always flush the 
pump before the fluid dries on the displacement rod, 
page 14. Relieve the pressure, page 12.

Never allow the pump to run dry of the fluid being 
pumped. A dry pump will quickly accelerate to a high 
speed, possibly damaging itself. If your pump acceler-
ates quickly, or is running too fast, stop it immediately 
and check the fluid supply. If the supply container is 
empty and air has been pumped into the lines, refill 
the container and prime the pump and the lines with 
fluid, or flush and leave it filled with a compatible sol-
vent. Be sure to eliminate all air from the fluid system.
