GENERAL USE AND MAINTENANCE
Switching from Fresh Water Flush to Recirculating Flush / Recirculating Flush to Fresh Flush modes
This unit can be converted from fresh water fl ush to recirculating fl ush with just a fl ip of the lever on the 3-way valve. The
3-way valve is located in the right rear corner of the unit, in the back of the sink. The hatch in the corner protects the valve
from being tampered with. To change from fresh fl ush to recirculating mode, and vice versa, open the hatch, and turn the
yellow handle of the valve in the opposite direction of where it currently is. The unit is in fresh water fl ush mode when the
handle is pointing up, and is in recirculating mode when the handle is pointing down. Replace the hatch when completed.
Opening The Sink
The sink holds the fresh water for hand wash as well as for the fresh
water fl ushing operation of the waste tank. The lid of the sink is
hinged and locked with a keyless lock for ease of accessibility. To
unlock the sink, insert a long thin object
(the key for the lock on the
T.P. Dispenser works well)
into the 1/4” hole directly below the bottom
of the sink lid, and while pushing down on the front of the lid of the
sink, push the
(key)
in to release the catch, and lift up the lid.
Trouble Shooting
PUMP WILL NOT RETURN UP WHEN PRESSED DOWN WHEN UNIT IS IN FRESH WATER FLUSH MODE:
The hoses that go
from the sink to the tank and pump are reversed. Carefully lay the unit on it’s back. Loosen the clamp holding the hose on
the bottom of the sink as well as the clamp holding the hose on the intake port of the pump. Remove these hoses and place
the hose that was going to the tank to the intake port of the pump, and place the hose that was going from the intake port
of the pump onto the fi tting on the bottom of the waste tank. Tighten the clamps, stand the unit back up and retest.
Locking/Unlocking the Unit
(Optional)
If this unit is equipped with an optional exterior lock, it can be locked to prevent unwanted usage in the evening or weekend
hours when no one is on site. This is done by turning the lock to the right and removing the key. When it comes time to
unlock the unit, insert the key and turn all the way to the left, and then back to the upright position.

Winterizing the unit
Start winterizing the unit by opening up the drain plug on the sink, and making sure it is completely drained. Reinstall
the drain plug. Pump the foot pump on the sink several times until there is nothing but air coming out of the sink tap.
Pump out the contents of the waste tank. Clean the inside of the tank with a pressure washer or hose Pump the foot
pump to run the fesh water through the pump and hoses. Pump out the waste tank again and pump the foot pump
several times while doing so to be sure that no water remains in the hoses or pump.
Remove the cover from the soap dispenser. push the locking tab on the mounting plate towards the wall, and slide the
soap dispenser body up and off the mounting plate. Pour any left over soap into your soap container and thoroughly
rinse out the soap dispenser body with warm water. Place the soap dispenser body back on the mounting plate, and
reinstall the lid.
