
For ease of transportation and installation, the filter
media is NOT loaded in the pressure tank, but delivered in
separate bags of 1 Cuft; it must be loaded on-site, after
positioning of the pressure tank.

The gravel underbedding is already preloaded in the
pressure tank.
FILTER MEDIA LOADING
1.
Move the pressure tank to the correct installation
location; position it on a flat and level surface. Make sure
to leave enough space for ease of service.
2. Position the riser assembly upright and centred in the
pressure tank; plug the top of the riser tube with a piece
of tape or clean rag, to prevent filter media from entering
the tube.
3. Place a funnel on the pressure tank opening and fill the
pressure tank with the filter media; make sure the riser
assembly remains centered in the pressure tank.
4. Rinse the pressure tank opening to remove any filter
media from the threaded section.
5. Unplug the top of the riser tube.
CONTROL VALVE
6.
Make sure the O-ring in the riser insert and the tank O-
ring (around the threaded section of the control valve) are
in the correct position.
7. Screw the top distributor onto the control valve.
8. Lubricate the threaded section of the pressure tank, the
top of the riser tube and the tank O-ring of the control
valve; use a silicon-based lubricant.
9. Lower the control valve straight down onto the riser tube,
until the riser tube is correctly inserted in the riser insert;
then push it down firmly and screw it onto the pressure
tank.
