Sump Pump
The shower sump is located under the floor of the cabin and can be accessed by removing the
deck plate in the cabin sole lid. The shower sump switch on the AC/DC panel must be on for
this pump to operate. The sump collects drainage from the enclosed head shower. The shower
sump contains a filter which should always be installed when using the shower to prevent the
sump pump from becoming clogged. See
“Cleaning” on page 6–1 for maintenance
information. Similar to a bilge pump, the sump pump is activated automatically by a float
switch to discharge the collected water overboard via a thru hull. The shower sump also
collects and discharges condensation from the air conditioner and should be turned on
whenever the air conditioner is in use.
Vacuflush Head System
The vacuflush head consists of a virtuous china bowl, vacuum pump with tank, and a holding
tank. To operate the head, the head and fresh water switches on the DC panel must be in the
"on" position. This provides power to the vacuum pump, and pressurizes the fresh water
system. Since this unit uses freshwater, it is not necessary to open a seacock prior to use.
Instructions on the operation of your vacuflush head are as follows:
1. Verify that the switches on the DC panel are in the "on" position.
2. To add water prior to flushing, raise the flush lever on the bowl until the desired level is
reached.
3. To flush, depress the flush lever sharply until contents clear the bowl. A sharp popping noise
is normal when the vacuum seal is broken and flushing begins. Be sure to hold the lever
down for 3 seconds.
Located on the aft console wall is a monitor which displays the fill level of the holding tank.
When the tank is filled, it can be discharged overboard or emptied through the deck pump-out
fitting. Following are instructions on both operations:
Overboard Discharge
1. Open the discharge seacock located under the sole floor with the discharge I.D. tag. This
seacock must be open prior to discharge to prevent damage to the discharge pump. To
access, open the access plate in the sole floor.
2. Supply power to the pump at the DC panel using the switch labeled holding tank discharge.
3. Engage the pump using the key switch in the Tank Manager panel on the outboard head
wall. Turn the switch to the start position momentarily and release. The key will return to
the “auto, off” position. The discharge pump will run until the Tank Manager panel indicates
the tank is empty and turn off automatically.
4. Turn the key to the “off” position.
N O T I C E
Do not dispose of sanitary napkins or other nondissolving items in the toilet. Also, do not attempt
to flush facial tissue, paper towels, or large quantities of toilet paper.
