WARNING: Risk of electric shock. Connect the control amplifier to a properly grounded,
grounding-type receptacle protected by a Ground-Fault Circuit-Interrupter (GFCI) or Residual
Current Device (RCD). Do not remove the grounding pin from the plug or use a grounding adapter.
IMPORTANT! Keep insulating materials away from the control amplifier. Provide an unobstructed air
space around the control amplifier to permit cooling.
NOTE: The control amplifier can be positioned vertically or horizontally.
Remove the control amplifier from the box.
Install the mounting brackets to the control amplifier.
Position the control amplifier flush or recessed from the front of the studs.
Using the wood screws provided, secure the control amplifier to the framing. Use the anchors
provided if securing to a wall material other than wood.
NOTE: The transducer terminals and wires are numbered to identify the correct connections. When
required, the control amplifier can be removed to aid in the wire connection process.
Securely attach the transducer wires to the transducer terminals on the control amplifier. The white
with black wires are the positive (+) leads, and the solid white wires are the negative (-) leads.
If equipped, connect the chromatherapy connector to the chromatherapy terminal on the control
amplifier.
Baths with chromatherapy and heated surface: Connect the inter-connect cable from the heated
surface control to the control amplifier.
Baths with heated surface: Connect the inter-connect cable from the heated surface control to the
