Important Safety Instructions
Read before beginning any work on the heater
 Read, understand, and follow all instructions.
 DO NOT permit children to use or operate this heater
 WARNING—FOR INDOOR USE ONLY.
 Do not permit any electrical appliance, such as a light, telephone, radio, television,
or microphone within 5’ of the pool
 A clearly labeled emergency switch must be provided by the installer. The switch
must be readily accessible to the occupants & shall be installed at least 5 feet
(1.52m) away, adjacent to, and within site of the pool.
 Heater and pool are intended for use as described in this manual. Do not use at-
tachments not recommended by the manufacturer.
 Never drop or insert any object into any opening.
 This Heater will need an electrical contractor provided & installed Ground
Fault Circuit Interrupter (GFCI).
 A green colored terminal is provided within the terminal compartment. To reduce
the risk of electric shock, connect this terminal to the grounding terminal of your
electric service or supply panel with a continuous green insulated copper wire
equivalent in size to the circuit conductors supplying this equipment.
A pressure wire connector has been provided on the Heater to permit connection
of a #8 AWG solid copper bonding conductor between this unit and all other electri-
cal equipment and exposed metal in the vicinity, as needed to comply with local
requirements.
Important Warnings
 The main power to the Heater System & all other electrical components should be
turned off before anyone enters the pool. Even if the Thermostat or Timer have
been paused, the heater functions, live electrical circuits are still present.
 Do not operate the pool until it is full. Running the Heater or other accessories
without proper water level may cause the system to operate at abnormally high
temperatures.

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.

Step 2
Electrical
 IMPORTANT NOTE : Due to the risk of electrical shock, a licensed electrician experienced in spa/
baptismal pool heaters should install this unit in strict compliance with the National Electrical Code
and any state or local code which may apply. Units are required to have a clearly labeled emergen-
cy switch provided by the installer as part of the installation. The switch must be readily accessible
to the occupants and shall be installed at least 5 feet (1.52 meters) away, adjacent to, and within
sight of the unit.
Wiring the Heater
 Remove 2 Phillips head screws from the top of the front cover of the heater and hinge the cover for-
ward.
 Note the location of the terminal block inside the heater. The ter-
minals on the block are marked Line 1 (L1), Line 2 (L2), Neutral
(N), and Ground. Connect the input service wires to the appropri-
ate terminal. Connect the ground wire to the ground lug. NOTE:
The installer shall provide a Ground Fault Interruption Circuit to all
electrical connections for the heater and accessories
 Close and secure the cover.
 Connect the pump using the receptacle located on the side of the
heater.
Installation of the Accessory Controller
The controller lays loose on the mounting pad.
There are mounting brackets if you wish to drill and
screw it down.
Plug cable from controller into heater.

Installation of Auto Fill and Auto Water Level Control
NOTE: It is the responsibility of the owner/installer to verify the overflow drain port supplied will offset the
incoming flow of water.
Installation of the Fill Port (2 PIN Connector)-
1. In a convenient location, close enough to the heater to allow connection of the pig tail, drill a 1 1/8”
hole approximately 6” above the floor of the baptistry.
2. Smooth hole on both sides. Slide the gasket over the threads of the fill port and push it through the
hole. Install and tighten the nut to the back of the baptistery. Apply silicone as necessary.
3. Install the fill device using Teflon tape on all threaded connections.
Installation of the Auto Drain (3 PIN Connector)-
Following the baptistry installation instructions for location, install the floor drain.
In a convenient location, pipe in the auto drain unit before the junction of the over flow drain (see draw-
ing). Control wiring on the auto drain is 20’ long, but additional control cable (by others) may be spliced
to extend its length
Installation of the Water Level Pressure Switch (4 PIN Connector)-
1. In a convenient location, drill a 1 1/8” hole, 10” below the rim of the baptistery.
2. Smooth hole on both sides. Slip the gasket onto the water port and slide it through the side of the
baptistery. Install the nut and tighten securely. Silicone as necessary.
Overflow / Wall Fitting Floor fitting
There may be extra wall fittings
that are used in other applications

Air Switch Installation
This heater is supplied with 2 air switches, each with 10’ of tube, to control start/stop and fill/drain. The
air switches can be mounted on the lip of the pool or any other convenient location.
The air button in the heater package allows for NON-ELECTRICAL start/stop of the system and will
override the time clock function. System operation is paused, but live electrical circuits are still present
inside the heater.
The second air button controls fill & drain functions. After installing the air button, plug it into the
receptacle on the Controller.

Operation of the Heater
 Fill the baptismal pool with fresh water to the proper level (6” below the top of the pool, but at least 3” above
the water return line (outlet fitting). Never operate the pump or heater without water in the system. Resulting
damage from dry operation is not covered by the warranty.
 Turn the power on to the heater from the main breaker. Water should now circulate. If water is not circulating,
turn the power off and refer to the Trouble Shooting Guide at the back of this booklet.
 Set the thermostat to the desired temperature.
 Check the water temperature using a thermometer (by others) until the desired temperature is reached. Adjust
the thermostat until a comfortable setting has been reached.
 Select the operational switch on the front of the heater to operate the system by the time clock or allow the
system to continuously operate.
Check for Proper System Operation
 Fill the pool with water. The pool is considered full when the water level is 6” below the top of the baptismal
pool.
 Turn the thermostat to the OFF position
 Set the Timer Mode Switch to the #2 position (continuous operation)
 Turn on the power at the breaker.
 The system is operating properly if the system is idle.
 Turn up the thermostat. The pump should start running and, once pressure builds in the pump, the system will
begin to heat. The amber “Heater On” light should now be illuminated.
 If the light does not come on, TURN OFF THE POWER. Refer to Trouble Guide .
Operation of the Time Clock
The system includes a 7 day time clock to allow for automatic control of the system.
 Set the system timer by turning the outer dial clockwise only until the present time and day are aligned with
the pointer on the dial. Do not attempt to turn the timer counter clockwise or permanent damage to the timer
will occur.
 Each tooth on the timer, when pushed out, represents 2 hours of operation. Consult the Temperature Rise
chart on the page 8 for mathematically estimated heating times. Time on the chart does not allow for heat
rising off the pool, so additional time may be necessary.
Operation of Auto Fill / Auto Drain System
When the air button is pressed, and the water turned on, the water level pressure switch will allow the fill port to run
water into the pool. When the water level reaches a point 4” above the water level pressure switch, the fill port will
turn off. The water level will then be approximately 6” below the top of the baptistery to allow for displacement dur-
ing usage. Should the water level drop 2” below normal, the water level pressure switch will activate the fill port
and refill the baptistery to the proper level. These levels are preset at the factory and should not require adjust-
ment.
When the pool is full and the auto fill system is activated the auto drain system can be activated by depressing the
air button once. This will disable the auto fill system and automatically open the electric drain.
Pressing the air button again re-activates the fill system and closes the drain.
If the system is draining and filling at the same time, flip the toggle switch on the drain valve to the oppo-
site position (see pg 10 for switch location on valve)

Important OPERATIONAL Warnings
 The main power to the heater system and all other electrical components should be turned off be-
fore anyone enters the pool. Even if the thermostat or timer have paused the heater functions, live
electrical circuits are still present!
 Do not operate the pool until it is full. Running the heater or other accessories without proper water
level may cause the system to operate at abnormally high temperatures, premature failure of com-
ponents, and unnecessary tripping of the high limit switch.
 Do not heat water in excess of 102°F. A temperature of 100°F is considered safe for healthy adults
only. Hotter water increases a risk of hypothermia. Young children, elderly persons, persons
having medical problems and persons on medications should have special consideration.
 Pregnant women need to be alerted to the danger of fetal damage and should consult their
physicians before being baptized.
 Always check the water temperature using an accurate thermometer. Thermostats installed in the
system may error in regulating water temperature by as much as 4°.
 Never, never tamper with the controls!. Scalding may occur if safety controls are not in proper
order.
 If freezing temperatures are expected, turn off the Heater system, drain the pool, then turn off the
electrical power. Follow the Operation Instructions on page 9 for restarting the Heater.
