INSTALLATION INSTRUCTIONS FOR GRT75-PF-RFS PET FOUNTAIN

Important: Read all instructions and refer to local codes
prior to installation.

l Local soil conditions may require more gravel for

drainage.

l It is recommended to include a supply stop

appropriately located on the supply line.

l An in-line PRV installed on the supply line is

recommended to ensure a working water pressure of 40­60 psi.

l A water filter should be installed on the supply line if

sediment or mineral content is a problem.

l Provide 30" x 30" x 6" deep concrete pad minimum.

Prepare trench for water supply line and waste line (if
required). At fountain location prepare hole to trench depth
and large enough for a person to work. Lay supply and
waste into trench allowing extra length to be trimmed
during hook-up.

Depending on code and design requirements, drain may
be open, French or sanitary connection. For French drain,
place a minimum of three cubic feet of gravel under drain
opening. Local soil conditions may require more gravel
drainage.

Refill trench and hole, compacting back fill as required.
Leave sufficient depth in hole to accommodate concrete
pour.

Prepare the slab area surrounding fountain spreading and
compacting gravel as necessary. Prepare form
approximately 6" diameter to protect supply and waste
stub outs.

If required, fix 1/4”-20 UNC L-bolt anchors by others in
position arranging L-bolts according to pattern indicated
and pour concrete to grade. Leave enough thread for
mounting base. Ensure concrete top surface is flat and
level. If concrete has cured use appropriate ½” concrete
anchoring hardware by others following the manufacturer's
installation recommendations.

For freeze resistant option refer to

-FRU manual #9938-340-0M1.
