lnstal lation lnstnuctions
Liquidator 2 is supplied fully assembled, ready to be installed on top ofyour tank, near the edge except for the Guide Pipe, which must bepurchased separately and cut to length. lnstallation is straightforward,
regardless of whether the tank is full or empty.

What you will needPipe:

2" round (plastic or galvanised steel). Actual OD = 66.3r, (2 3/8'),OR,
2" square galv. Steel or aluminium tube. 50mm sq. tube will also fit.
Wall thickness up to 2mm (0.'10")
Pipe length = tank height approximately.

Drills: 4mm (11164"), smm (3/16"), 12mm(112")
Tools: Phillips head screwdriver, knife, hacksaw, file, silicone sealant
For Extended Mounting (see below): Vz" pipe and sockets will also be needed.

I Ghoose position
The best place is where the indicator can readily be seen from your prelened direction.
Close to the tank access hole is easiest for installation.

2 fitl Float with waten
The float needs the weight of the water to provide the driving force forthe system. Unscrew the cord Attachment Fitting, insert the drinking
straw provided just inside the hole (about 20mm (3/4 ") only), submerge
the Float under water, and suck the air out. Water will rush in around thestraw until only a small bubble remains inside.
Screw the Fltting back in so that it seals.

3 frlount Float Pulley Housing
The Float Pulley Housing can swivel up to 450 to adapt to steep roofs. lt can also be reversed inside the Swivel Cover - better for shallow slopes as it gives more clearance for theFloat Cord. Decide which is best for your situation. Be careful not to lose the circlip.
lf the roof is curved or ribbed the base can be shaped to suit - file or grind as necessary.

Adjust location if necessary to avoid any obstacles on the tank such as pipework, bulges,overflow ouflet, etc,, and trace its outline on the tank roof. Check that the Guide Pipe, when
fitted into the Main Pulley Housing, will be at least 1Omm (3/8") clear of the tank wall.
Drill Float Cord hole (12mm (112") dia.) vertically, through the roof , offset 1 7mm (0.67") horizontally from the axle centre.
Untie the cord from the float, pass it through the hole, and re-tie it to the float inside the tanklf the cord b beyond reach from the tank access hole, use a stick with a nail in the end as a"croof to capture it, Check that the cord won't rub on the edge of the hole. lf so, enlarge it
or drill andpr hole.
Place the Fbat Pulley Housing back on its marked position on the tank . rool and fasten it.tothe roof with the two long stainless steel self tapping screws provided. Drill right through witha 4mm ( 11|il1 dia. drill, then enlarge the holes in the housing with a
5mm (316J dia. drill.

4 *epane Guide Pipe BaseThis should be vertically below the Main Pulley Housing. lt can bescrryed to the floor, with a central screw. For sloping or uneven
floors, the thin rim on the underside ol the Base can be liled away tocompensate.
No floor? No need for the Base - just bury the end of the Pipe in theground, or concrete it in.

5 rit Guide Pipelnsert the Guide Pipe fully into the Guide Pipe Base (or hole in theground), rest it against the Main Pulley Housing (held horizontally),
and mark where the top of the pipe has to be cut. Cut the pipe to length, remove burrs.
Note. 50mm square tube is slightly smaller than 2" ( 50.8mm) so it will be slightly loose
inside the aluminium castings. Tape wrapped around the tube ends, silicone sealant, oradhesive will take up the gap.

Before fitting the Guide PipeHousing, adjust the Countenre{/tards by pulling themthrough, taking up the excess ardftare* knot
underneath.
The Counterweight should hang just der d ihe bottom,
with the lndicator hard up against the u&side of the Main
Pulley Housing and the Float f ully up insib te tank.
Cut off the excess cord below the knd

7 Final Assembly
Gently lower the Counterweight insile, and the Indcdor
outside, down the Guide Pipe ard btiltem hang mdertfieir
own weight. Push the Main Pulley l-lousing onb tfn @ ofthe Guide Pipe (it can swivel on the Flod tuIey l-h-sing)Iornm Gap

8 GheckAccunacy
Make sure the reflective red barrl on the lndicator is leveiwith the centre of the float. This is true liquid level, fl-he
float, hanging from its cord, is always half-immersed.)
Minor adjustments can be made by undoing and retying thestop knots in the cord, for both Float and lndicator.

I Attach Stay
Ensure the Pulley Housings are in iheir correct positions
and the Guide Tube is vertical.
Fix one end of the aluminium Stay to one of the lugs on the Main Pulley Housing and theother end to the tanli roof, with the two short stainless steel self-tapping screws supplied.
Bend and/or twist the Stay such that it lays flat on the tank roof. Drill size for the screw holes
is 4mm (11/64").

I0 Seal Gaps
Silicon sealant can be used to seal/secure the Main Pulley Housing and Guide Pipe Baseto the Guide Pipe. Then, seal around the base of the Float Pulley Housing/Tank roof withsilicone sealant. Likewise, seal the gap between the Swivel Cover and the Float Pulley
Housing. Screw heads and pipe socket threads may also be sealed.
After sealing, the only point of entry for insects, dust etc., is where the indicator cord
emerges. However, it is virtually impossible for insects, dust, etc., to enter the tank as thecord passes through the close fitting sellaligning grommet tucked up inside the Main Pulley
Housing.

Extended Mounting
The Float Pulley Housing can be located much further from the edge, high up on the roof, as
in the diagram. The Vz" black polypropylene threaded socket with can be replaced with stan-dardlz"pipe and fittings, readily available from hardware stores in either plastic or metal.
When rethreading the cord tie a bulky knot at the end to make sure it doesn't accidentaliydisappear into the Main Pulley Housing.
Liquidator 2 is supplied with enough cord for a 1.5m (5 feet) horizontal extension on a 3m(10 feet) high tank. The extra length is gained from the underside of the counterweight. lnstead of cutting ofi the excess cord after retying the knot below the Counterweight as in Step
6, reposition the knot so that the excess cord is added to the float cord.
Quite likely, a longer stay will be needed. This can be made from metal strip, angle, or tube.

Pipe Stub Mounting
The Float Pulley Housing fits neatly on either 2" round pipe and 2" square tube which may
be a more convenient place for mounting.

Maintenance
Liquidator 2 should keep working well lor many yearc. lt is weatherproof hn not perfectly
sealed. Like any mechanical device exposed b the outdoors, Liquidator 2 should be checked
periodically for correct operation, accidental damage, wear, cobwebs, irpress of dust, etc.

Ghemicals
Liquidator 2 can be used on chemical tanks, but the onus is on the installer to make surethere are no adverse effects on the parts exposed to the chemical.
The only part in direct contact with the liquid is the polypropylene float. However splashing,fumes or vapours may affect the polyethylene cord attachment fitting and polyester cord
inside the tank. Other parts outside the tank may also be affected by chemical fumes.
For some chemicals it may not be advisable for the float to be filled with water. Other liquidscould be used, or alternatively, granular material such as sand. The gross weight of thefloat and contents should be 550 grams approximately for use in water and other liquids
with a similar density. lf the specific gravity is significantly less than 1.0, the buoyancy willbe less and the float should be lighter. For example if the SG is 0.8 then the float shouldbe about 't 0% lighter, about 5009m. Likewise for denser liquids, the weight may need to beincreased.
Examples of Liquids: water, acids, oils, fertiliser, waste water, molasses, wine, chemicals,etc., almost any liquid that is compatible with the polypropylene float.
