Vacuflush Head System (Option)
•
The optional vacuflush head system uses freshwater (not raw water) to flush waste from the toilet to the holding
tank.
• If the system is equipped with a macerator pump, waste may be pumped from the holding tank into the water
through an underwater discharge seacock (where regulations permit). The macerator switches are located at the
helm station and must both be pressed simultaneously for pumping to occur.
• If your yacht does not include a macerator (macerator delete option), waste can only be pumped out of the holding
tank to the receptacle on the deck for dockside pump-out only.
Air Conditioning & Heating (Option)
Your yacht may be equipped with an optional air conditioning & heating system. Both heating and cooling are con-
trolled from the same panel. Please refer to the air conditioner/heater manual for detailed operating instructions.
• Before operating the air conditioning and heating system, make sure the breakers on the AC main distribution
panel are activated and verify the system’s raw water pickup seacock is OPEN. The seacock must remain OPEN
anytime the air conditioner/heater is in use.
• The raw water pickup strainer should be checked periodically for debris according to the directions given in the
Raw Water Strainer section of this supplement.
