Pressure Switch Adjustment
Pressure switch is normally factory set for universal
spa applications. Heater must not be installed more
than five feet above water level or five feet below. If the
heater is installed below the spa level or if a two speed
filter pump is used it is necessary to reset the pressure
switch as follows:
1. With pump and heater on, turn adjustment knob
clockwise until a click is heard.
2. Turn adjustment knob counter clockwise 1/4 turn.
3. Turn pump off and on several times. Heater should
shut off immediately. If it does not, repeat steps
above until proper adjustment is made.
Shut Down
Turn off electrical power to heater at main disconnect
when draining spa.
MAINTENANCE
Spa Water Chemistry
Chemical imbalance can cause severe damage to
your heater and associated equipment. Maintain your
water chemistry according to the chart on page 8. If
the mineral content and dissolved solids in the water
become too high, scale forms inside the heat exchang-
er tubes, reducing heater efficiency and also
damaging the heater. If the pH drops below 7.2, the
heater will be severely damaged. This will result in cor-
rosion of the heat exchanger.
Heat exchanger
damage resulting from chemical imbalance is not
covered by the warranty.
Element Inspection and
Replacement
The element assembly head is removed as follows:
1. Turn off electrical power to heater at the main dis-
connect and turn off water supply line.
2. Drain the heater.
3. Remove access panel.
4. Disconnect all wires to terminals of elements.
5. Remove four bolts holding element in place.
6. Remove element assembly.
7. Replace element assembly and gasket using
reverse procedure.
Removing the Aquastat
1. Turn off electrical power to heater at main discon-
nect.
2. Remove screw holding aquastat to mounting
plate.
3. Disconnect wires from aquastat and control knob.
WARNING:
The use of alcohol, drugs, or medica-
tion can greatly increase the risk of fatal
hyperthermia in pools and tubs.
NOTE:
Hyperthermia occurs when the internal tem-
perature of the body reaches a level several degrees
above the normal body temperature of 98.6°F
(37°C). The symptoms of hyperthermia include dizzi-
ness, fainting, drowsiness, lethargy, and an increase
in the internal temperature of the body. The effects of
hyperthermia include (1) unawareness of impending
hazard, (2) failure to perceive heat, (3) failure to rec-
ognize the need to exit pool or tub, (4) physical
inability to exit pool or tub, (5) fetal damage in preg-
nant women, and (6) unconsciousness resulting in a
danger of drowning.
WARNING:
ONLY QUALIFIED PERSONNEL
SHOULD ATTEMPT MAINTENANCE ON THIS
EQUIPMENT (N.E.C. ARTICLE 100-1971) (MAIN-
TENANCE MUST BE DONE WITH MAIN
DISCONNECT OPEN).
