Figure 31. Air fi lter replacement.
Remove the wing nuts retaining the bottom panel
and remove the panel. Grasp the bottom edge of the
fi lter and pull it downward and to the right. Replace
it only with the specifi ed part available from a Jandy
representative. Push the replacement fi lter into the
tracks at the front and rear of the fi lter box.
4E. Electrical Trouble Shooting
WARNING
ELECTRICAL SHOCK HAZARD. This heater
contains wiring that carries high voltage. Con-
tact with these wires may result in severe injury
or death.
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify proper operation after servicing.
This section describes procedures for checking
the electrical power and control components of the
heater one at a time and in the order they appear in the
control circuit.
These procedures require a Volt-Ohm meter with
0-150 VAC range, and 0-1000 Ohm resistance range.
Figure 32 shows the power and control circuits, and
where to take measurements. Location numbers in
circles have been added, and will be referenced in the
following sections.
As stated at the beginning of this manual, some
of these procedures are hazardous. Only a qualifi ed
service technician should service the heater.
4E-1. 115V Electrical Power Supply
The electrical components of the Hi-E2 pool
heater are designed to operate with supply voltage
ranging from 103V to 126V at 60 Hz. Measure supply
voltage at the "hot" and "neutral" wirenut connections
in the heater electrical junction box (identifi ed as
points A and B on the wiring diagram). If no voltage
is present, correct this external to the heater. Circuit
breakers, time clock settings or similar devices may be
the problem. Voltage outside of the above range may
be due to poor wiring, poor connections, other loads
such as air conditioning compressors or to an electric
utility company problem. Arrange for cor rec tion of the
voltage as appropriate.

4E-2. Control Circuit Trouble Shooting
The heater controls are in a 24V 60 Hz circuit
with operating and safety controls basically arranged
in a series circuit. Trouble shooting is done by probing
for voltage at various points in the circuit to determine
which com po nent is preventing operation. Check
points are indicated on Figure 32. The rec om mend ed
procedure steps through the circuit in a sequential
way, but verifying voltage at any of the numbered
points confi rms that all prior components are OK.
Experienced technicians may be able to shorten the
process by going directly to one of the intermediate
test points.
4E-2a. Transformer
Attach one lead of the voltmeter to the
transformer terminal with a yellow wire attached to it,
which is point 11 on Figure 32. (This lead can be left
in place for most of the testing.) Touch the free lead of
the meter to the transformer terminal with a red wire,
point 1. The meter should show 20-28 volts. If there is
no voltage, replace the transformer.
4E-2b. Fuse
Leaving the "common" voltmeter lead in place
at point 11, touch the free probe to point 2. This is the
terminal block screw attached to the red wire from
the in-line fuse, and absence of voltage indicates a
defective fuse. If there is no voltage, inspect the rest
of the wiring to be sure that there is no "short" such as
contact of a terminal with the heater chassis or another
terminal. Correct any such condition and replace the
fuse.
4E-2c. Fireman Switch and External
Probe for voltage at point 3, the other con nec tion
of the terminal block, which has a white wire
connected to it. If there is no voltage, the time clock
switch or other ex ter nal interlock may be mis-adjusted,
mis-connected or defective. Correct this external
problem.
4E-2d. Limit Switches
Probe for voltage at point 4, which is the water
