Step 1
Pre-Plan & Assembly
Assemble the Heater and Pump to the base using the instructions provided
Locate the Heater in an accessible area adjacent to and at the same approximate elevation as the
floor of the baptismal pool. For best heating results the heater must be located within 20’ of the bap-
tistry.
The system uses a circulation pump that relies on water pressure in the baptistry to operate. If the
pump is to be located near or above the water level an EQAS AGP pump will be required .
The final installation must be such that no person can touch water and any source of electrical pow-
er at the same time.
The final installation must be indoors with a minimum of 6” from any combustible materials including
the combustible materials in the floor.
Allow for adequate clearance for servicing the Heater and any options installed.
Locate the system where, if any connections were to leak or rupture, water damage will not occur.
Under no circumstances will FSI nor any of its vendors or agents be
responsible for any water damage.
Minimum piping to be used is 1 1/2” I.D. schedule 40, PVC water pipe on all inlet and
outlet connections.
Electrical service required for the EQAS AS-5 is 40amp, 240v. For the EQAS AS-5+EQAS Booster
a 60 amp, 240 volt is needed.
With the Heater in a location as described above mark a centerline of the suction fittings on the side
wall of the pool. Look behind the side wall to assure the area is clear and does not penetrate any
structural reinforcement. The mark should be 3” to 4” above the floor of the pool. DO NOT DRILL
THE HOLE! Next mark the location of the return fitting. The return fitting should be installed above
the suction fitting and at least 6” below the top of the pool. During usage, the return fitting must be
5” below the water line to prevent excessive turbulence.
Flow Control valves (red handles) are included, but not required for installation. These valves
should be placed in the suction and return lines so water from the baptistry or in the heater system
will be contained during maintenance or removal of the heater. The valve on the suction side
must always be wide open. The valve on the return line may be adjusted to control the flow
rate. This allows full water into the pump at all times.
At this time, consider the location of the Auto Fill, Water Level Controller, and Electric Drain plus any
optional items ( UV Sanitizer, Filter, Skimmer, etc.) that may be included in the final installation. Re-
view the installation recommendations for those items as well as their location to assure a proper
installation.
With the Heater in its final position, in line and level with the suction fitting location, determine the
exact position of the Heater by preassembling the plumbing headers and circuits. Be sure to align
the fittings and support the Heater in such a way that the plumbing is not put into tension
with the baptistery wall. Such tension can cause unnecessary leaks and noise due to vibra-
tion. Installer may wish to consider using flexible PVC piping if code allows for its use.
After all parts have been preassembled and aligned with hole locations, using a 2 3/4” hole saw, drill
the fiberglass and install the Suction and Return fittings. Install the fittings with the supplied gasket
on the interior (finished) side. Use silicone (not supplied) on the fitting flanges to create a watertight
seal. Position the Heater and glue the required joints.
When all glued parts are dry, re-assemble, making sure all o-rings and gaskets are in place on all
union connections. Union connections should only be hand tight. Over tightening these connec-
tions can cause them to crack and leak and are not covered by warranty. If the union connection
doesn’t feel tight, check the gasket for debris and /or replace the gasket.
