Lavac Installation
Handle position (angle of operation) and/or outlet
direction can be varied by rotating pump body
(26) relative to back cover (35) (See exploded
diagram p.8).
If back cover (35) is rotated ensure air bleed hole
in back cover is re-drilled at lowest point.

therefore all hose clips must be
tight.
8. An important part of the Lavac
installation is the air bleed valve
which has to be located at the top
of the loop of the inlet pipe. Drill a
5mm (
1/18
”)diameter hole at the
top of the curve of the inlet pipe If
the top of the inlet pipe is in a
clothing locker, ensure that the
clothes do not obstruct the air
bleed valve. Similarly, if the hose
is hard up below the deck, drill the
hole slightly to one side at the top
of the loop. For installations on or
above the water line, insert the
white plastic bleed plug.
For installations below the water
line, use the black plastic plug.
(Set of bleed plugs TLZ9251).
9. Attach the self-adhesive oper-
ating instructions to the bulkhead
near the pump. We recommend
that a suitable rubber stop is
placed on the bulkhead behind the
Lavac unit to avoid possible dam-
age to the lid when opened.
inlet and, particularly, the outlet
hoses. If it is completely unavoid-
able to use right angled fittings in
the outlet hose, then rigid plastic fit-
tings should be used having an
inside radius of not less than 31mm
(2“). Do not use sharp angled
plumbers fittings which can easily
cause a blockage.
4. Establish a position for the pump
where the pump inlet is no lower
than the bowl top.
5. Bolt or screw the pump in posi-
tion using 6mm (¼“) diameter bolts
or screws ensuring that the flow
arrow on the pump is vertically up
or certainly not more than 45° from
the vertical.
IF THE PUMP IS MOUNTED IN
ANY OTHER WAY THE INSTALLA-
TION WILL BE INEFFICIENT IN
OPERATION AS THE INLET VALVE
CANNOT SEAL EFFECTIVELY.
6. Cut the 38mm (1½“) diameter
outlet hose to the lengths required.
Be sure to allow enough hose from
the top of the pump to take the loop
above the waterline at maximum
heel of the boat. For motor vessels
this is high enough at maximum
angle of roll. Attach the two cut
lengths of hose from the bowl to the
bottom (inlet) of the pump and from
the top of the pump (outlet) to the
outlet seacock.
7. Connect the 19mm (¾“) bore
inlet hose to the bowl inlet, having
allowed for a loop similar to the outlet
(see point 6) and attach the inlet
hose to the inlet seacock.
PEASE NOTE: It is absolutely
essential that all joints are 100%
sealed. No air leakage is permissible
