EL/GL SERIES (Mach 3) CONTROL WITH ML551/ML554 PANEL
The ML551 and ML554 panels can be used with the
EL8000, EL5000, EL2000 and EL1000 systems. This user
guide lists all features that are available. Your spa may
not respond as described in this document as specific
operation varies by system and equipment used. If your
spa is not fully equipped, the panel buttons on your
spa control may not be laid out as shown. Functions
not accessible by this panel may be accessible by a
larger panel such as the ML900. Example: The ML551
and ML554 panels can be used with all EL8000 systems
equipped with three pumps, but pump 3 cannot be
controlled with this panel unless the system does not
have a blower and an additional Jets button is added to
the panel in its place. In other cases, pump 3 can be
controlled with an optional auxiliary panel.
The pump responsible for heating and filtration (pump 1
low on non-circ systems, or the circ pump on circ
systems) will be referred to simply as the pump.
Timeouts refer to a preset length of time that a
function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can
cause a function to operate longer, while faults can
cause a function to operate for a shorter length of time.
The system keeps track of timeouts regardless of other
conditions occurring.
In multi-button sequences, if buttons are pressed too
quickly in sequence, they may not register.

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 “Cool” or “Warm.”
