Graco A-25 Recirculation / Pressure Relief Lines, Install Fluid Temperature Sensor FTS

Page 19

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.

Install Fluid Temperature Sensor (FTS)

Install FTS between main hose and whip hose. See Heated Hose manual for instructions.

Setup

Connect Heated Hose

NOTE: See heated hose manual for detailed instruc- tions for Graco heated hoses.

NOTICE

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) min- imum.

1.Turn main power OFF.

2.Assemble heated hose sections, FTS, and whip hose. See Heated Hose manual for instructions.

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.
