60 MSPA-MP Metapacks Service Manual
Ozonator Does Not Work!
If ozonator isn't working, carry out the following tests to correct the
problem:
To increase the life of the relay, a "snubber" circuit is used on the ozonator relay. With
this type of circuit, if no ozonator is connected to an output and relays are open, the
voltmeter will still get a reading of around 60 volts. This is normal.
It is important to take voltage reading with ozonator connected to the pack.
Power must remain On.
2• Verify if "Filter Cycle" indicator
(steady indicator light) appears
on keypad.
If not, start up a filter cycle (refer
to MSPA-MP User's Manual).
1• Verify low level programming to
make sure that ozonator is pro-
grammed properly (see Low
Level section).
N.B.: On new systems, if a pump,
blower or light is turned on during
filter cycle, the cycle will be interrup-
ted and will resume only 40 minutes
after the last active output has been
turned off. This delay is to prevent
excessive ozonator activation.
During this time, "Filter Cycle" indicator
will flash in a different sequence (3 short,
1 long, 3 short, 1 long, etc.).
To prevent excessive water tempera-
ture due to overly long filter cycles, the
system will automatically cancel a filter
cycle after 3 hours if water temperature
climbs more than 2°F above set point.
In this case, "Filter Cycle" indicator flashes
on the display.
3• Measure voltage between ozonator
white and black wire connectors:
240 VAC ozonator: P60& P30
120 VAC ozonator: P46 & P30
You should read:
≈240 VAC for a 240 VAC ozonator
≈120 VAC for a 120 VAC ozonator
4• Replace ozonator if you get a good
voltage reading.

5• Replace ozonator fuse if voltage
reading isn't high enough.
6• Replace board if you still don't
get a voltage reading. (Refer to
"How to Replace the Board"
section.)
