Xylem JABSCO 29120-5000 Installation Instructions Manual page 4

Option 3: Toilet waste discharging into holding tank, top of hold-
ing tank is above discharge elbow at anytime.
(See Figure 3 below).
YOU MUST fit a 38mm (11/2") Vented loop fitting, Jabsco part num-
ber 29015-0010.
• If there is ANY possibility that the discharge elbow may be be-
low the top of the tank at ANY time, a ventilated anti-syphon
loop must be fitted in the outlet pipework to ensure that the con-
tents of the tank do not syphon out through the bowl.
• Arrange the outlet hose to form a loop which is at least 20 cm
(8") above the highest possible level that the tank may reach,
and fit the Vented Loop at that highest point.
Option 4: Toilet waste discharging into holding tank, discharge el-
bow always above top of holding tank.
(See Figure 3 below).
• Run the outlet hose up from the discharge elbow to form a loop at
least 30cm (12") higher than the discharge elbow.
• This will create a water seal at the Joker Valve that will prevent
bad odours from escaping through the toilet.
YOU MUST fit a 38mm (11/2") Vented loop fitting, Jabsco part num-
ber 29015-0010.
• If you fit a vented loop at the top of the hose loop this will ensure
that you can keep some water in the base of the toilet without
risk of it being siphoned away.

• Half fill the bowl with warm fresh water.
• Keeping the Flush Control Lever (key 23) in the Shut (
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
