Balboa Instruments ML900 Installation Instruction

EL SERIES (Mach 1) CONTROL WITH ML900 PANEL
The ML900 panel can be used with the EL8000, EL5000, and EL2000 systems. This reference card lists all features that are available
for this panel. If your spa is not fully equipped, the panel buttons on your spa control may not be laid out as shown or respond as
described in this document.
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 the spa and maintain the water temperature in the
Standard mode. You can exit Priming mode early by pressing "Warm" or "Cool."
