INSTALLATION INSTRUCTIONS (cont.)
These instructions are written assuming 60Hz, 120V pow-
er supply. Verify the electrical requirements of the bath
unit before installation. Refer to the equipment labels for
voltage and frequency requirements.
Note:
This bath is designed for indoor use only. The elec-
trical equipment must not be exposed to direct or indirect
water or moisture contact. The electrical equipment must
also be protected from dust and other airborne debris
before, during and after installation.
A licensed electrician must provide the “dedicated” electri
-
cal service protected by a GFCI. The location of the GFCI
must be at least five (5) feet [152cm] away from the inside
surface of the bath, accessible for regular testing. Use
copper conductors only.
DANGER - RISK OF ELECTRIC SHOCK:
Connect only
to a circuit protected by a Ground Fault Circuit Interrupter
(GFCI). In the unlikely occurrence of a current imbalance
in the power conductors, the GFCI will interrupt the power
to the bath.
WARNING: The electrical service to the GFCI must not
be interrupted by any control device. Likewise, the
electrical service from the GFCI to the bath control
should be direct and not interrupted by a switch. Nev-
er use a switch in conjunction with a control device.
This will VOID THE MANUFACTURER’S WARRANTY.
The pumps are supplied with an electrical bonding lug to
allow connection of a solid copper bonding conductor be-
tween the unit and other electrical equipment and exposed
metal in the area as may be required by local code.
Note:
The air blower’s exterior housing is made of all plastic ma-
terials and does not require a bonding conductor.
Grounding is required. The unit should be installed by a
qualified service representative and properly grounded.
Install the service connection at least six (6) inches [15cm]
above the sub floor.
All local and state electrical and plumbing codes
must be observed.
Where there are no local codes, the
National Electric Code (NEC) and Uniform Plumbing Code
(UPC) shall be observed. It is the responsibility of the
installer/owner to determine specific code compliance prior
to installation of the product.
Note:
In the Commonwealth of Massachusetts, installa-
tion is to be done by a Massachusetts licensed plumber.
DANGER - Do not alter the factory installed wiring. All
building materials and wiring should be routed away
from the equipment or other heat-producing compo-
nents of the unit.

CONTROL BOX CONNECTIONS
All power cords must be connected into the proper 20 amp 120VAC GFCI dedicated circuit for the system (The LS640
Premier and Signature Edition models require (1) 20 amp and (1) 15 amp 120V GFCI circuit). Some models may have
more than one control box mounted on a stand that is temporary secured to the packing board for shipping. These boxes
must remain on the control box stand so that the two boxes can communicate properly via infrared communication. All
controls should be located to permit access for inspection and servicing. Depending on the options ordered on the bath,
more than one outlet may be required.
