OPTIONAL EQUIPMENT OPERATING INSTRUCTIONS
INLINE HEATER
For Whirlpools - The factory installed inline heater used on MTI whirlpool systems is designed to maintain
the temperature of the water during the hydrotherapy bath. The heater is not designed to heat cold water.
The heater will activate automatically when the pump is engaged. There is no separate control for the
heater. The thermostat is pre-set at 102°F. The heater must be plugged into a110 VAC,15 AMP, GFCI
protected outlet. Both the pump and inline heater must be plugged in for system to operate properly. The
heater has an indicator light to conrm that it is working.
For Soakers and Air Baths - The inline heating system for soaking tubs and air baths is manually
activated by an on/off device, typically a push button style. This system gently recirculates the bath water
through the inline heater, with negligible disturbance to the water. The heatsoak system requires a dedi-
cated 110 VAC, 20 AMP, GFCI protected outlet. Both the pump and inline heater must be plugged in for
system to operate properly.
RADIANCE Note: If your tub is equipped with an air system,
the Radiance control will be on the keypad (shown on page 11 & 14)
To turn the system on, press the button on the
touchpad. The light on the touchpad will be on.
Radiance is designed to be left on continually as the
initial heating can take about an hour. The system
uses less energy than a standard light bulb. To turn
the system off, press the button again. The system will
turn off in the event of a power surge or power failure.
Must have access to transformer box for future
servicing - test prior to installing.
WATER LEVEL SENSOR AND TIMER
The Water Level Sensor control will prevent the pump from operating until the water level reaches 1 - 2 inches
above the highest jet. If the water level falls while the pump is operating, the unit will automatically shut off.
(Note: Designer Collection tubs run on a 20 minute timer and then automatically shut off.)
MICRO-JET CLUSTER PACKAGE
Micro-jets provide pinpointed hydrotherapy, typically to the back or neck. To
adjust or shut off the micro-jets’ water ow, turn the volume control divert-
er valve. Depending on the number of micro-jets, you may have one or
two volume control diverter valves, each controlling one set of micro-jets.
IMPORTANT! YOU MUST TURN THE VOLUME CONTROL FOR THE
MICRO JETS DOWN UNTIL YOU ARE SITTING IN FRONT OF THEM. IF YOU
ACTIVATE BEFORE, WATER MAY SPLASH OUTSIDE THE BATH.
Important information for whirlpool baths equipped with the micro-jet package. This specialty massage
therapy system must be in the OFF position under the following conditions:
1. When the water in the tub is below the highest micro-jet, the pillow is above the water line.
2. When you want to operate the whirlpool’s lower jets only.
3. When operating the Fill-Flush, or Simple Touch System.
Turn the volume control diverter valve to adjust air ow and shut off the micro-jets.
If your tub is equipped with more than four micro-jets, they may be operated by their own pump, on/
off control & air-volume control. See pages 15, 17 & 18 for photos and functions of keypads for tubs
equipped with micro-jets.
