Blowing Agents
Some foam blowing agents will froth at temperatures above
90°F (33°C) when not under pressure, especially if agitated.
To reduce frothing, minimize preheating in a circulation sys-
tem.

Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump:
use ground wire and clamp (supplied). Connect
ground clamp to a true earth ground.
Gun:
ground through connection to a properly grounded
fluid hose and pump.
Fluid supply container:
follow local code.
Solvent pails used when flushing:
follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a non-conductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
Maintain grounding continuity:
When flushing or
relieving pressure, hold metal part of the gun firmly to
the side of a grounded metal pail, then trigger the gun.
NOTICE
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
•
When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
•
Always clean the fluid inlet strainers after flushing.
•
Check with your material manufacturer for chemi-
cal compatibility.
•
When changing between epoxies and urethanes
or polyureas, disassemble and clean all fluid com-
ponents and change hoses. Epoxies often have
amines on the B (hardener) side. Polyureas often
have amines on the B (resin) side.
