Loosen hose clips and disconnect the hose ends from both seacock hose tails. Pump the handle (key 36)
to drain the toilet pump and ensure that all water is drained from the toilet system.
Remove the base drain plug (key 9,10).
Open any secondary valves.
Disconnect the discharge flange (key 14) from the pump (avoiding the need to remove the hose from the
discharge elbow (key 16).
3. SERVICING - WINTERISATION
Drain the complete system, both as protection against frost damage and to discourage the growth in the
pipework of anaerobic bacteria that cause unpleasant smells.
If you plan to overhaul the toilet in the spring, this is a good time to disassemble it and take the components
ashore to make the overhaul easier.
If you leave the toilet disassembled and, if the seacocks are opened when the craft is afloat, water will flood
in and may cause the craft to sink, which may result in loss of life.
Therefore, you MUST attach a warning notice to the seacocks and, if possible, wire the seacocks shut.
ATTACH WARNING NOTICE!
Replace the base drain plug securely.
Reconnect all hose ends and secure them with their hose clips.
Replace the joker valve in the discharge elbow.
Reconnect the discharge elbow and hose to the cylinder using the discharge flange, whilst relieving any
leverage from the discharge hose. If you do not, the joint may not seal.
Fasten down the seat, lid and pump handle to prevent use and attach a warning notice.
If you are not disassembling the toilet:
Remove the 2 screws (key 31) that secure the discharge flange (key 14) that holds the discharge elbow
(key 16) and hose to the pump cylinder (key 18).
Loosen hose clips; disconnect the inlet hose and the flushing water hose (key 13) from the top of the pump.
4. SERVICING - OVERHAUL
REMOVE THE PUMP ASSEMBLY AS FOLLOWS
Open ( ) the Flush Control (key 24) before lifting off the valve cover assembly and picking up the top

Remove the handle and the seal assembly by following the SERVICING INSTRUCTIONS for SEAL
Remove the 6 screws (key 30) that secure the valve cover (key 31).
DISMANTLE THE PUMP ASSEMBLY AS FOLLOWS
Withdraw the piston assembly (key 28,29) and prise off the piston O-ring (key 29).
Do NOT remove the bowl from the base
Clean and disinfect all parts - refer to OPERATING INSTRUCTIONS for CLEANING. Remove scale from
the cylinder bore.
Inspect the top and bottom valve gaskets (key 21) and the joker valve, and renew them if they are
damaged, stiff or covered with scale. Automatically renew the seal assembly and the piston O-ring. Use the
other parts in the kit as necessary.

Locate the valve seat (key 19) on top of the cylinder, locate the top valve gasket (key 21) on its pegs on top
of the cylinder, locate the valve spring (key 35) on its peg in the valve cover, and Open ( ) the Flush Control
(key23) before refitting the valve cover (key 27).
Secure the discharge elbow and hose to the cylinder, using the discharge flange (key 14), BEFORE you
refit the pump assembly to the base (key 7), so that the joint is not under leverage from the discharge hose.
If you do not, the joint may not seal.
Secure the pump assembly to the base whilst relieving any leverage from the discharge hose. If you do not,
the joint may not seal.
Push on the new O-ring (key 29) and lubricate with petroleum jelly (vaseline).
Following the SERVICING INSTRUCTIONS for SEAL REPLACEMENT fit the new seal assembly (key
32,33,34), the piston assembly (key 28,29) and the handle (key 36).
Lubricate pump cylinder bore with petroleum jelly (Vaseline).
Locate the joker valve (key 15) in the discharge elbow(key 16).
Locate the bottom valve gasket (key 16) on its pegs on the base.
Examine all hoses throughout their length for chafe, kinks and splits under hose clips. Check all hose clips
for corrosion and replace worn or damaged parts.
Reconnect all loose hose ends and secure them with their hose clips.
Ensure that the base drain plug (key 9,10) is securely in place.
REASSEMBLE THE PUMP AS FOLLOWS
Do NOT remove the hose from the discharge elbow.
Remove the 4 screws (key 17) that secure the pump cylinder to the base.
Lift off the pump assembly and pick up the base valve gasket (key 6) and the joker valve (key 14).
!
CAUTION: Gripping the piston rod with a tool anywhere except on the
16mm (5/8") below the handle damages the surface in a way that causes
rapid seal failure.
HAZARD RISK - Seacocks opened by mistake
!
CAUTION: The use of anti-freeze is NOT RECOMMENDED, as it is mpossible
to ensure that it penetrates the complete toilet system. If, for any reason,
anti-freeze is used it MUST be glycol based.
!
CAUTION: Do NOT lubricate top or bottom valve gaskets. Do NOT
apply sealing compounds to any gaskets or hose connections.
