Toilet - Hydro-Vac Operating Instructions; After Initial Checks; If Using The Fresh Tank Supply; Routine Maintenance - Monaco DIPLOMAT 2004 Owner's Manual

The Hydro-Vac toilet operates on a simple principle of accelerating pressured
water through a Venturi jet to create a vacuum. City water supply or the water
pump and an accumulator tank can be used to supply the pressurized water. The
venturi jet water macerates and discharges waste to the black holding tank. The
push button on the toilet begins the flushing process.
Prior to Use:
Make the following checks and adjustments:
• Check all plumbing connections for obvious problems.
Make repairs as needed.
• The fresh water supply is available.

If using the fresh tank supply:

• The water pump should be fully primed.
• The pressure pre-charge in the accumulator tank should
be adjusted to 4 psi below the pump cut-in pressure of 25
psi.
• Close the rim-feed valve on the back of the bowl.

After Initial Checks:

Make the following initial adjustments:
• Flush the toilet until any air has been purged out of the
system.
• Check the entire plumbing for any leaks. Make repairs as
needed.
• Check the water pressure system gauge located in the service bay.
• Adjust the rim feed to the desired level by opening the rim-feed
valve at the back of the toilet. A higher rim-feed will allow a higher
water level in the bowl, but less powerful flushing action. Likewise,
a lower water level in the bowl gives a more powerful flushing
action.

Routine Maintenance:

The system has been designed for trouble-free operation. No moving parts
ever touch the waste stream, so clogging is very unlikely. However, regular
checks of the plumbing components should be performed to identify leaks or
minor problem.
Using a tire air pressure gauge, one that reads low air pressure, check the
accumulator tank pressure bi-monthly. The accumulator tank has a tire valve for
checking the air pressure in the tank. In the event air pressure needs to be
increased, a manual pump is recommended. Compressed air flow can overcharge
the tank too quickly causing the tank to rupture.
