INSTALLATION (cont’d)
NOTE! Placing a tape of the same color as of the Material Delivery Hoses (red
for the Iso (A), blue for the Poly (R)) on each Transfer Pump would be a good
method for minimizing errors in connection.
a. Make sure that the Inlet Valves on the Proportioner are closed.
b. Connect one end of the Polyol (R) Material Delivery Hose (¾” thread)
to the Proportioner Polyol (R) Inlet Valve and the other end to the
Polyol (R) Transfer Pump.
c. Connect one end of the Iso (A) Material Delivery Hose (½” thread) to the
Proportioner Iso (A) Inlet Valve and the other end to the Iso Transfer Pump.
d. Connect the air hose to the Transfer Pumps after ensuring each Transfer Pump
Shut-Off Valve is CLOSED.
NOTE! To avoid errors in connection, the Coupling connections of the Iso (A)
and Poly (R) Material Delivery Hoses are different sizes, making it difficult to
swap connections.
e. Ground the Transfer Pump as recommend by the material supplier. The movement
of product inside the Hoses can cause static electricity and produce electrical
discharges.
f. Connect air to the air line coming off the first section of hose (90-110 psi).
