Recirculation / Pressure Relief Lines
Do not install shutoffs downstream of the PRESSURE RELIEF/SPRAY valve outlets (BA, BB). The valves function as over pressure relief valves when set to SPRAY. Lines must be open so valves can automatically relieve pressure when machine is operating.
If circulating fluid back to the supply drums, use high pressure hose rated to withstand the maximum working pressure of this equipment.
If Recirculating to Supply Drum: Connect high pressure hose (R) to relief fittings (BA, BB) of both PRESSURE RELIEF/SPRAY valves. Route hose back to component A and B drums. Refer to manual 309852.
Alternate recirculation hoses (requires adapter fittings):
249508 - ISO (A) (moisture guard) red hose, 1/4 in. (6 mm) ID; #5 JIC fittings (m x f); 35 ft (10.7 m) long.
249509 - Resin (B) blue hose; 1/4 in. (6 mm) ID, #6 JIC fittings (m x f), 35 ft (10.7 m) long.
Setup
1.Turn main power OFF.
2.Assemble heated hose sections, FTS, and whip hose; see manual 309572.
3.Connect A and B hoses to A and B outlets on Reactor fluid manifold (FM). Hoses are color coded: red for component A (ISO), blue for component B (RES). Fittings are sized to prevent connection errors.

Manifold hose fittings (VV, WW) allow use of 1/4 in. 
and 3/8 in. ID Reactor heated fluid hoses.
4.Connect cables (SS). Connect electrical connectors (NN). Be sure cables have slack when hose bends. Wrap cable and electrical connections with electrical tape.

Connect Heated Hose
See manual 309572 for detailed instructions for
Graco heated hoses.
The fluid temperature sensor (FTS) and whip hose 
must be used with heated hose; see page 19. Hose length, including whip hose, must be 60 ft (18.3 m) minimum.
