Note regarding EL and GL systems: Mach 3 EL and GL systems function identically, but conform to different International requirements. This user guide will refer to EL systems for the sake of simplicity, but the information given applies to both EL and GL products.

EL/GL SERIES (Mach 3) CONTROL WITH ML700 PANEL
The ML700 panel 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 ML700 panel 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 “Warm” or “Cool.”
Icon Legend
Heat Icon - Indicates different stages of heating.
Jets Icon - Spins fast on high speed; spins slow on low speed.
Blower Icon - Biggest in highest speed; smallest in lowest speed.
Fiber-Optic Light Icon - Spins when the wheel is on; stands still when wheel is off.
Light Icon - On dim, the LCD will show the center circle plus one quarter of the light beams. Half of the light beams will show on medium brightness, and all of the light beams will show on bright.

Time 
When time hasn’t been programmed, the “
” icon flashes. To set the time, press “Time” then “Mode/Prog.” Use the “Warm” and “Cool” buttons to adjust time. See previous page for more detailed instructions. (Time settings on EL1000 and some EL2000 systems are not preserved in the event of power loss; time will have to be reprogrammed upon each power up.)
If your spa has an optional pH/ORP sensor (not available on EL1000 and some EL2000 systems), pressing “Time” twice will display the current pH level; pressing it three times will display the current ORP.
Setting the Time
Once the spa has been properly connected the first time (every power up on the EL1000 and some EL2000 systems), notice the “
” icon appearing on the screen.

Temp Set (80°F - 104°F / 26.0°C - 40.0°C)
The last measured temperature is constantly displayed on the LCD. Your spa’s set temperature range may vary from range shown above depending on your manufacturer’s settings.
Note that the last measured spa temperature displayed is current only when the pump has been running for at least 1 minute.
Warm/Cool 
Press the “Warm” or “Cool” button once to display the set temperature. Each time either button is pressed again, the set temperature will increase or decrease depending on which button is pressed. After three seconds,
the LCD will automatically display the last measured spa temperature.
Mode/Prog 
This button is used to switch between Standard, Economy, and Sleep modes. Press “Mode/Prog” to enter mode programming, press “Cool” to cycle through to desired mode (LCD flashes until confirmed), then press “Mode/Prog” to confirm selection.
Standard mode maintains the desired temperature. Note that the last measured spa temperature displayed is current only when the pump has been running for at least 1 minute. The “
” icon will display until the mode is changed.
Economy mode heats the spa to set temperature only during filter cycles. The “
” icon will display until mode is changed.
Pressing “Jets 1” while in Economy mode puts the spa in Standard-In-Economy mode, which operates the same as Standard Mode, then reverts to Economy Mode automatically after 1 hour. Both the “
”
and “
” icons display in this mode. During this time, a press of the “Mode/Prog” button will revert to Economy Mode immediately.
Sleep mode heats the spa to within 20°F (11°C) of the set temperature only during filter cycles. The “
” icon will display until mode is changed.
Standby Mode
Pressing “Warm” or “Cool” then “Jets 2” will turn off all spa functions temporarily. This is helpful when changing a filter. Pressing any button resets the spa. On some systems the “Jets 1” button will control the pump in Standby Mode (“Drain Mode”). In this case, press any other button to exit. System will revert to previous mode after 1 hour.
Jets 1 
Press the “Jets 1” 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.
