7. Connect the Transfer Pump/ Heated Hose Assemblies/ Air Supply and Air Dryer
systems as required. Review the Installation Instructions for each to ensure proper set-
up and operation.
8. Install the Material Transfer Pumps as follows:
WARNING! If Transfer Pumps have been previously used, pay
special attention to connect each Pump to “its” specific material.
Inadvertently changing the Transfer Pumps will cause a
chemical reaction rendering them useless.
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, 6-8 bar)
