EL/GL Series - Mach 3
ML240 Quick Reference Guide
Initial Start-up
When your spa is first actuated, it will go into Priming
mode (after displaying some configuration information).
Please see the M-7 Installation Instruction Manual for
complete instructions on Power-up and Pump Priming.
The Priming mode will last for up to 4 minutes and
then the spa will begin to heat and maintain the water
temperature in the Standard mode. You can exit Priming
mode early by pressing “Temp”.
Temp
Press the “Temp” button once to display the set
temperature. To change the set temperature, press the pad
a second time before the LCD stops flashing. Each press of
the “Temp” button will continue to either raise or lower the
set temperature.
If the opposite direction is desired, release the pad and let
the display revert to the current water temperature. Press
the pad to display the set temperature, and again to make
the temperature change in the desired direction.
After three seconds, the LCD will automatically display the
last measured spa temperature.
Jets
Press the “Jets” button once to turn pump 1 on or off, and
to shift between low and high speeds if equipped. If left
running, the pump will turn off after a timeout period. The
pump 1 low speed timeout on some systems may be as
long as 4 hours.
On non-circ systems, the low speed of pump 1 runs
when the blower or any other pump is on. It may also
activate for at least 1 minute every 30 minutes to detect
the spa temperature (polling) and then to heat to the set
temperature if needed, depending upon mode. When the
low speed turns on automatically, it cannot be deactivated
from the panel; however, the high speed may be started.
