Ensure that this INSTRUCTION MANUAL reaches the owner, 
skipper or operator of the craft as it contains essential safety

Operating Instructions

The toilet is one of the most used pieces of equipment on 
your boat. Correct operation of the toilet is essential for the 
safety and comfort of your crew and craft.

1. First use

After  periods  without  use  the  toilet  may  benefit  from 
lubrication.

Open inlet and outlet seacocks (and secondary valves if 

• 

fitted).
Half fill the bowl with warm fresh water.

• 

Keeping the Flush Control Lever (key 23) in the Shut 

• 

(

) position, pump out the warm water.

2. Normal use

Open  inlet  and  outlet  seacocks  (and  secondary  valves  if 
fitted).

Before use, ensure that there is enough water in the 

• 

bowl to prevent the toilet paper becoming compacted at 
the bottom of the bowl.

If the bowl is empty, move the Flush Control Lever (key 23) to 
the  Open  (

)  position  and  pump  the  handle  (key  17)  up 

and down until the flushing pump is primed and water enters 
the bowl.
Then Shut (

) the Flush Control.

Operate the pump with long, smooth strokes for efficient 

• 

and easy operation.
During use, pump as necessary to keep the contents of 

• 

the bowl low enough for comfort.
Use good quality hard or soft household toilet paper, but 

• 

do not use more than necessary.
After use, keep the Flush Control Shut (

• 

) and pump 

until the bowl is empty.

When the bowl is empty, Open (

• 

) the Flush Control 

again, and continue to pump until all waste has either 
left the boat, or reached the holding tank (allow 7 
complete up/down strokes per metre (yard) length of 
discharge pipework).

Then Shut (

) the Flush Control and pump until the bowl 

is  empty.  Always  leave  the  bowl  empty  to  minimise  odour 
and spillage.

AFTER USE:
-  SHUT (

) THE FLUSH CONTROL.

-  SHUT BOTH SEACOCKS

HAZARD RISK - Accidental Damage

If the toilet is connected to ANY through-hull fittings that are 
below the waterline at any time, and if the toilet or pipework is 
damaged, water may flood in, causing the craft to sink, which 
may result in loss of life.
Therefore,  after  every  usage,  both  seacocks  (or  secondary 
valves) MUST be shut.
Whenever your craft is unattended, even if only for a very short 
period  of  time,  both  seacocks  (even  if  secondary  valves  are 
fitted) MUST be shut.

Ensure that ALL users understand how to operate the 

• 

toilet system correctly and safely, including seacocks and 
secondary valves.
Take special care to instruct children, the elderly and 

• 

visitors.

SHUT SEACOCKS!

NOTE:  Do not put anything in the toilet unless you have eaten 
it first, except toilet paper. Do not put in: Sanitary Towels, Wet 
Strength Tissues, Cotton Wool, Cigarettes, Matches, Chewing 
Gum or any solid objects, Petrol, Diesel, Oil, Solvents of any 
kind or water more than hand hot.
