PRS Startup Procedure (1200M) Mobilize & Rig in Equipment 1. Fill glycol bath with approximately 350 US gallons of 50/50 propylene glycol/DI water mix before use. Fill glycol to a level at least 6 inches above bottom of sight glass on heater expansion chamber and above the low level shutdown switch. CAUTION: If the glycol level is below the low level switch, the fuel gas system will not function and the burner will not light. See Figure 9. 2. Mobilize equipment to customer site. Spot PRS a minimum of 10 feet (3m) from tube trailer and 30 feet (10m) from customer supply point. 3. Connect 1” high pressure hose from tube trailer to Inlet #1 (or Inlet #2) & secure hose with whip restraint. 4. Connect 2” low pressure supply hose from 2” discharge valve of PRS to customer supply point. Secure hose with whip restraint. NOTE: Ensure customer supply point has a purge valve in place upstream of the customer supply valve including a check valve to prevent back flow of gas into PRS. 5. Connect grounding cables from tube trailer to PRS and to customer supply point. 6. Open & secure control panel doors. 7. Remove cover on spark arrestor of heater. 8. Ensure the glycol level is visible in the sight glass in the expansion chamber of the heater. Ensure 6 inches can be seen in the sight glass and is above the low level shut down sensor when cold. CAUTION: do not over fill as the glycol will expand as it is heated and can overflow the top hatch. 9. Release clamp on smokestack and raise to vertical position using hand crank pully system and secure with bolts. 10. Open the controller boxes of PCV-104 and PCV-108 and set both controllers at 0 psig. 11. Ensure main fuel gas supply valve V-10 is closed. See Figure 2. 12. Visually inspect that dust caps are on pressure safety valves.   Figure 2  TGT PRS Manual Page 2
