Important Safety Information
WARNING: Risk of electrical shock! All procedures described in this service manual
must only be performed by qualified personnel, in accordance with the
standards applicable in the country of installation and, whenever
possible, with the equipment powered off. When connecting the
equipment, always refer to the wiring diagram affixed to the inside of
your spa pack’s power box cover! This diagram always prevails over
the wiring diagram at the end of this manual.
All information given subject to technical modifications without notice.
In order to be as helpful as possible, most sections of this manual were written in two
distinct formats: problem-solving solutions are described using both troubleshooting
flow charts and step-by-step procedures.
They should be used in conjunction, flow charts giving a global overview of specific
problems while step-by-step procedures are more detailed.
Although this manual has been prepared with great care, some information may seem
erroneous or unclear to you. In this case, please do not hesitate to contact us with
your remarks or questions.

Note: For systems manufactured before 1999, if P43 & P44 are
missing, use a #6 gage (4 mm dia.) cable and install it
between Line 1 and Line 2.
1 x 230 VAC (32 A) input supply wiring
Proper wiring of the electrical service box, GFCI and spa pack terminal
block is essential.
•Make a visual inspection for signs of miswiring. Refer to the supplied wiring
diagram. Call an electrician if necessary.

POWER & GROUND CHECKGFCI Trips!
1• Verify if the GFCI is properly
connected.
2• If it is not, verify the GFCI wiring
diagram and reconnect it.
If the equipment is connected but nothing seems to work, the power supply
must be defective. Perform the following:
Note that in new installations, GFCI trippings due to miswiring are very common.
If the breaker is properly wired, GFCI trippings can occur when the total amount of current
drawn by the spa exceeds the rating of the breaker. Such an occurrence, however, is very
unlikely since each output of the spa pack is individually fused and fuses will blow before the
GFCI trips.
A current leak to the ground will also make the GFCI trip. If one of the components is faulty
and there is a leak of more than 5 mA, the GFCI will trip to prevent electrocution.
Several different models of GFCIs are available on the market. Note that our illustrations are
generic.
3• If the GFCI is properly connected but
still tripping, disconnect all outputs,
including the two wires of the heater &
the light cord.
4• If the GFCI still trips, replace the
transformer.
5• If the GFCI still trips even after the
transformer has been replaced:
a- Disconnect the power input wires.
If the GFCI still trips, the cable must
be defective.
Call an electrician!
b- If the GFCI stops tripping, replace it.
c- If the GFCI is still tripping, replace
the board referring to the "How to
Replace the Board" section of this
manual.
If it stops tripping, reconnect one com-
ponent at a time until the GFCI starts
tripping. Replace the defective com-
ponent.

PROGRAMMINGJumper Setup
2• To change a setting, simply pull the
jumper out using a pair of pliers and

It is possible to change some parameters of your MSPA-1-AS Spa Pack by
positioning specific jumpers located on the board.
To access the jumpers, first remove the plastic cover inside your MSPA-1-AS Spa Pack
power box referring to the "How to Replace the Board" section of this manual.
On your system, jumper functions may differ from the following. Check the supplied
wiring diagram affixed to the inside of the power box metal cover for your spa pack’s
specific functions.
Jumper location
Position 2Position 1
1• The jumpers are located on the upper
right section of the board.
Jumper JMP1: Current limiting option
Jumper JMP1 is used to limit the current drawn when the 2 pumps are used.
Position 1 (HC): The heater may not be turned on at the same time as pump 2.
Position 2 (LC): Pump 2 is disabled. Also, the heater may not be turned on if pump 1
is running at high speed or if the blower is on.
Jumper JMP2: Temperature display unit
Position 1: Temperature will be displayed in degrees Fahrenheit (ºF).
Position 2: Temperature will be displayed in degrees centigrade [Celsius] (ºC).
Jumper JMP3: Pump 1
Position 1: Two-speed pump.
Position 2: Single-speed pump.
Jumper JMP4: Pump 2
Position 1: Two-speed pump.
Position 2: Single-speed pump.
