Check Hoses For Leaks - Graco Power-Lock Instructions - Parts Manual

Check Hoses for Leaks

1. Connect fluid hoses to proportioner fluid
manifold (M). Red for hardener (ISO), blue
for resin (RES).
The manifold hose adapters (N, P) allow
use of 1/4 in. and 3/8 in. ID fluid hoses.
To check adapter tightness, torque as fol-
lows:
• A side (N) to 43-47 ft-lb (58-63 N•m).
• B side (P) to 55-60 ft-lb (74-81 N•m).
To use 1/2 in. (13 mm) ID fluid hoses,
remove the adapters from the propor-
tioner fluid manifold and install them in
the FTS swivel inlets.

2. For spray guns, close fluid valves on gun
fluid manifold. Remove manifold from gun,
see gun manual. Connect fluid whip hoses
to manifold.
3. Check that all equipment is properly
grounded. See proportioner manual.
4. Pressure check hose. See proportioner
manual for priming instructions. After all
lines are free of air check for leaks. If there
are leaks, relieve pressure as instructed in
proportioner manual. Tighten connections,
then pressurize again to ensure leaks have
stopped. Relieve pressure.
