Heads - Gray and Black Waters

November 03, 2016

 

The two bathrooms have two heads manufactured by Tecma.  They are of the suspended type, to facilitate cleaning of the floor.

In each bathroom there is a suspended bidet that matches in size and looks the Tecma heads.

The black waters can either go directly overboard or to a black water tank.  There is one black water tanks.

 

 

Procedures

Emptying Holding Tank

To empty the holding turn on the holding tank pump, located on the electrical panel on the bridge.

When the Maretron waste level meter shows 0, the tank is practically empty.  If the waste level meter shows a - (minus sign) the waste tank is dangerously overfilled.

 

Adjusting the Water Level in the Heads

To adjust the water level to the correct water level of 1 cm above the outlet hole in the ceramic bowl turn the shaft trimmer in the rear part of the control panel of the head located behing the head.

Equipment

 

WC

The two WC's are Tecma model Evolution.

The functioning cycle of the head is completely automatic and eliminates wastewater with a high performance turbine pump that allows a wastewater's drainage up to a height of 11 meters and a distance of 90 meters.  

They are connected to the cat's fresh water system. I find that less salt water is used on board the simpler is the maintenance of the equipment that uses water. The water is controlled by an electrovalve and a filter.  Should there be a shortage of fresh water, it is possible to connect the heads to the salt water system.

The control panel has two switches so as to leave the bowl absolutely empty when not in use.

For the WC and the holding tank only paper that passes the following test should be used:
Put a sheet of toilet paper into a one liter jar, add about 5 to 8 cm of water and shake for about 30 seconds.  The paper must mostly dissolve.

Each WC weighs 28 kg and draws 25 A, the electrovalve draws 5 A.

Purchased July 2006.
