a) Tank assembly
The GRAF Carat tank comes in two half shells, the upper of which has the aperture for the
tank dome. We supply GRAF Maxi tank domes.
Place the locating pins in the holes round the rim of the lower half, clean off every trace of
grit and dirt from the joint surfaces, lubricate then fit the rubber profile seal in the groove
round the perimeter. Turn the upper half to its correct orientation (two people needed,
and maybe four with the 6500 litre size) and lower it onto the locating pins, making sure
the seal mates with the upper and lower halves.
•
The Graf-patented quick connectors (wedges) secure the two halves together (and can
be disassembled if you choose). For the best results, work diagonally, in attaching the
connectors, i.e. after the first, say, at 12 o’clock, secure
a connector on the opposite side of the tank, at 6
o’clock. Then secure connectors at 3 o’clock and 9
o’clock etc. This ensures that the seal is compressed
uniformly. Knock them each tight with a rubber
hammer.
Triple fins of the dome
seal face inwards
•
The tank dome seal sometimes needs to be rotated 90
degrees before it is apparent which way it goes. The
single fin goes into the grove in the top of the tank. The
triple fins point towards the centre of the rim and hold
the dome (turret) when inserted. Mount the dome but
leave the man-hole cover off for the time being.
•
In the case of the extension sleeve (optional) the rubber seal should be fitted inside
the extension before the green lid is offered up.
•
The Graf Carat tank is supplied with the Graf Optimax Filter.
The filter is a self-cleaning
mesh filters. The holes in the turret of the tank are positioned to enable plug-and-play
fitting of the filter without the need for any drilling
