In an attempt to make this manual as useful as possible, it has been presented in two formats. Problem-solving solutions are described with Troubleshooting Flow Charts and also with Step-by-Step Procedures. The two formats together should provide an overall complete explanation, with flow charts providing an overview of specific problems, and step-by-step procedures giving more detailed information.Important Safety InformationWARNING:Risk of electrical shock! All procedures described in this servicemanual must only be performed by qualified personnel, inaccordance with the standards applicable in the country ofinstallation and, whenever possible, with the equipmentpowered off. When connecting the equipment, always referto the wiring diagram affixed to the inside of your spa pack’spower box cover! This diagram always prevails over the wiringdiagram at the end of this manual.

GFCI Trips!

If all connections are made, but nothing seems to be working, you probably have a power supply problem. Carry out the following tests to identify and correct the problem:

Note that for new installations, GFCI trippings due to miswiring are common.If breaker is wired properly, GFCI trippings may occur when total amount of current drawn by spa exceeds breaker rating. This is highly unlikely as each spa pack outputis individually fused, and fuses will blow before GFCI trips.A current leak to ground will also cause GFCI to trip. If any of the components is faultyand a leak of more than 5mA occurs, GFCI will trip to prevent electrocution.1•Verify if GFCI is properly connected.2•If it is not, verify GFCI wiring diagram and reconnect it.3•If GFCI is properly connected, but still tripping, unplug all outputs, including heater and light cord wires.4•If the GFCI still trips, replace transformer.If it stops tripping, reconnect onecomponent at a time until GFCIstarts tripping. Replace defectivecomponent.

GFCI Trips!

1•Disconnect incoming powerlines.If GFCI still trips, there mustbe a cable problem.Call an electrician!2•If GFCI stops tripping. Replace GFCI.3•If GFCI trips again, replaceboard. (Refer to "How toReplace the Board" sectionof this manual.)If GFCI continues to trip even after having replaced the transformer,carry out the following tests to correct the problem:

Jumper Positions

Certain MC-MP spa pack parameters can be modified by changing the position of jumpers on the board.Please check wiring diagram on inside pack cover to verify specific functions for our pack.Remove MC-MP power box cover to access jumpers.

Flashing Dots Displayed

Three flashing dots error condition indicates a pressure switch problem. Note: If remote heater is selected in the Low Level Programming, then this section does not apply.There must be enough water in the spa for normal operations. System may detect errorcondition if spa filter is dirty or if something restricts flow of water in piping.The heater will automatically shut down when error condition occurs.Power may remain On when the following steps are carried out.5•If you do not detect continuity,verify if pressure switch cable isproperly connected to pressureswitch and board.1•Verify if Pump 1 (or circulationpump if installed) is working. Ifpump is not working right, referto pump section of this manual.2•Make sure jumper is set pro-perly for circulation pump.3•If Pump 1 is working properly,turn it on by pressing Pump 1key (or start circulation pumpby increasing the set point) andtest continuity on pressure switch.4•If you detect continuity, go tostep #10.12MC-MP CE & AS Service Manual

6•Ensure adequate water flow in theheater and short two pressure switchterminals with jumper cable.7•If the three dots disappear, firstmake sure there is no blockage ofwater or air lock and check watervalve.If the installation is older than 2 years,replace the pressure switch and re-calibrate it.If installation is recent, try readjust-ing the pressure switch. If this is notpossible, replace switch.(Refer to "How to Adjust thePressure Switch" section of thismanual.)8•If the three dots still appear, theproblem may be either with switchcable or board.Remove plastic cover and replacecable.9•Replace board if error condition stillpersists.
