Operation of Water Pump
WARNING
The Containerized Latrine System ships with an antifreeze solution pumped into the
freshwater lines. The antifreeze solution is nontoxic, but unsuitable for drinking or washing.
DO NOT OPERATE THE LATRINE until the freshwater lines have been flushed.
NOTE
The use of a step aid may be required.
1. Remove priming cap (1) from the QDC fitting (2) on the pump (3).
2. Open the waste tank valve (4) and allow antifreeze to drain into the holding tank (5).
3. Close the sink valve (6), the waste tank valve (4), and the main commode valve (7).
NOTE
The use of a step aid may be required.
4. Using a clear funnel, fill the 1-inch QDC fitting (2) with the water obtained from priming the water line;
fill pump (3) until water begins to overflow out of the QDC fitting (approximately 11/3 gallons).
5. Recap QDC fitting (2).
6. Locate water pressure gage (8).
CAUTION
Do not turn on the circuit breaker (#2B) for the water heater. Applying power to a dry water
heater will burn out the heating element, making the water heater inoperative.
7. Set circuit breakers #9/11 in the breaker panel to the ON position.
8. Open the sink valve (6), the main commode valve (7), and the six commode supply valves (9).
9. Set water supply pump switch (10) to the ON position. Pump should operate immediately. Pump will
automatically operate when pressure drops below 20-psi, and will shut off between 32-psi and 40-psi.
10. To bleed air from the system, open the spigot (11) on the side of the sink stand. Close the spigot
when a steady stream of water is discharged. Then, open the spigot (12) at the end of the commode
supply pipe, in the stall closest to the door. Close this spigot when a steady stream of water is
discharged.
11. Open the faucets and flush each toilet to release any remaining air in the system.
12. The pump may be shut down by turning the water supply pump switch OFF.
