Priming Metering Pumps:
1.
Install ratio block onto gun head to keep the A&B materials separate for priming.
This will allow for no material waste for priming and ratio checks.
2. Set both pumps for longest pump stroke for priming. If either tank or pump
completely runs out of A or B materials, never re-prime fluid section with static
mixer attached. This could result in material cross over inside the gun.
3. Using the throat seal oil (TLS-ISO) provided with the system, pour oil into the
packing nut reservoirs, (see drawing VHPC-2200, item 3, part number VHPC-
2207 packing nut) ¾ full of TSL-ISO oil (TLS-ISO-800). This will protect materials
from drying on the piston rod which affects the life of the piston rod packings.
4. Fill both A & B containers with materials. Always keep the ISO tank lid on the
tank and slightly snug tighten to avoid moisture contamination and or crystals
from forming. Crystallized ISO will plug the fluid filter and will affect metering of
the system.
5. Be sure the pump pressure regulator is set to zero.
6. Have two clean containers available to catch the materials as they are dispensed
from the ratio block. Position the gun so that the ratio block separates the two
materials into the containers to prevent cross contamination.
7. With ratio block attached to gun head, pull the trigger on the gun and adjust the
pump pressure (clock wise) to begin cycling the pumping system. Once a steady
flow of both A & B materials, note if any fluid pressures for both materials. Very
little fluid pressure is required for ratio checks but the fluid gauge needle should
come off its stop even if an exact reading is not obtainable.
8. When using the ratio block, the two materials have not come into contact and no
solvent flush should be required at this time.
9. A ratio check or a gel test can be performed at this time
