C. ELECTRICAL REQUIREMENTS
The installation must have a Class A Ground-Fault
Circuit-Interrupter (GFCI). The GFCI protects against
line-to-ground shock hazard. Use a 120 V, 20 A, 60 Hz
dedicated service for the BodySpa.
3. SITE REQUIREMENTS
A. CLEARANCE REQUIREMENTS
Thedistance from therough floortothe finishedceiling or
header must be between 83-1/2” and 84” to provide
adequateclearancewhenassemblingthedoorenclosure
to the footbath. Be sure the ceiling and header are level.
B. STUD POCKET PREPARATION
NOTE: Carefully study the illustration at right before you
begin construction of the stud pocket. Follow the framing
details provided to ensure correct installation.
Use 2x6 framing for the tower wall to provide sufficient
space for the tower mounting frame and wiring, and
minimum2x4framingfortherestofthestudpocket.Make
sure you allow for access to the pump in the event the
BodySpa requires service.
Provide double stud support for the door enclosure wall
jambs. You must secure the door enclosure wall jambs
directly to the studs to obtain proper support and correct
opening dimensions. Expanding wall anchors will not
provide adequate support for the door enclosure
assembly.
You must install these stud supports to be within 3/8”
of plumb for proper door enclosure installation. Maintain
this tolerance to ensure a satisfactory, watertight
installation.
The footbath requires no additional bottom support when
the rough floor is plumb and level with respect to the stud
framing. If the rough floor is not level, shim it as needed.
Verifythatthedistance from the rough floor to the finished
ceiling is between 83-1/2” and 84”.
IMPORTANT: Leave studs exposed. You must secure

O. APPLY SEALANT
Door seals are an integral part of this door. However,
sealing with a quality clear silicone sealant is necessary
to ensure a properly functioning, watertight unit.
The required sealing procedure follows:
Mask both edges of joint to be sealed, maintaining a
joint width of 1/8” to 3/16”.
Apply a uniform bead of sealant. Smooth the bead with
your finger.
Remove the tape from the sealed joints immediately
after smoothing the bead.
Repeat for all areas to be sealed.
Very Important! Apply silicone sealant to the outside
