MACERATOR PUMP SYSTEM (IF EQUIPPED)
Your RV may be equipped with a macerator
pump system used to discharge waste from
the gray and black waste tank. The system
has a 1-1/2 inch diameter flexible hose that
runs from the pump (under the RV) and is
stored in an exterior storage compartment.
The system, when powered on, can
discharge waste (uphill if necessary) up to a
distance of 150 feet.
Open the hose compartment and pull
out the 1-1/2 inch flexible hose with the
attached dump connector. The dump
connector includes two connections: a
small removable cap for attaching a 3/4
inch garden hose, and a larger 3-inch
removable cap that allows it to attach to the
sewer outlet at the dump station.
Using the system:
1.
To make drainage easier, make sure the RV is level.
2.
Attach the dump connector to the 3-inch sewer outlet at the
dump station, or to a 3/4-inch garden hose and run the hose to a
dumping location.
3.
Open the black tank dump valve.
4.
Turn the Macerator power switch ON (switch lights up red) at the
hose storage compartment and the macerator pump will begin
sending waste through the dump hose.
5.
When the tank is empty, turn the macerator power switch OFF.
6.
Close the black tank valve.
7.
Open the gray tank dump valve.
8.
Turn the Macerator Power Switch ON.
9.
When tank is empty, turn the macerator power switch OFF.
10. Close the gray tank valve.
11. Unhook the dump connector, rinse it out and place the hose and
connector back into the storage compartment.
Macerator Bypass Valve
The Macerator Bypass Valve is located underneath the external hose
storage box. This bypass will allow you to gravity dump the waste
from the tanks straight down to a 3-inch sewer hose connection under
the trailer in the event there is a problem with the macerator motor.
The bypass valve also doubles as an emergency cutoff in the event
of a problem with the flex hose or dump connector. Closing the valve
stops waste flow out of the macerator pump and up to the flex hose,
but will divert waste to the main dump connector under the RV. Make
sure the main dump gate valve is closed until you are ready to empty
the black tanks.
PLUMBING SYSTEM
(See page 78 & page 79)
Garden Hose Connection
Dump Station Connection
To operate:
1.
Attach a 3-inch sewer hose
to the main dump connector
under the trailer and to a
sewer outlet at a dump
station.
2.
Open the desired black / gray (manual) drain valves, one at a
time (black then gray).
3.
The bypass valve is
normally open (handle is
pulled OUT). To bypass the
macerator, push the bypass
valve IN (turns off flow from
the macerator pump)
allowing waste to flow out of
the dump connector under the trailer via gravity.
The bypass valve for the macerator is typically pointing back
underneath the coach. Handle position is normally pulled OUT
(bypass closed). The valve position is by design, so it can't be
activated accidentally when system is operating normally.
4.
When finished, close the main dump gate valve under the trailer,
along with the black / gray dump valves. Disconnect the sewer
hose from the main dump connector and at the dump station.
Winterize the Macerator system
1.
Ensure all waste tanks are empty.
2.
Pour RV antifreeze into the toilet and down into the black water
tank.
3.
Make sure macerator bypass valve is pulled OUT. Turn the
macerator pump ON.
4.
Run the pump until antifreeze begins to discharge from the dump
connector attached to the flex hose.
Use a container (bucket) for capturing system fluid.
5.
Turn the macerator pump OFF.
6.
Drain the flex hose by holding it at a sloped angle to drain excess
water and return the hose to the storage location.
7.
As an added safety measure, push the Macerator Bypass valve
IN to bypass the macerator and let it drain.
8.
After draining make sure to pull the macerator bypass valve OUT
again.
De-winterize the macerator system
Emptying the black tanks in the spring will flush antifreeze out of the
macerator system.
