TYPICAL WORK INVOLVED FOR INSTALLATION OF MASTER SPAS SPA
16
system. The installation will require the purchase of a separate sub panel to feed the pa control
panel. An electrical wiring schematic is supplied in the drawings section.
All materials, equipment and labor needed to connect each electrical component must be
provided.
Wiring and conduit must be installed as required by the local regulatory authority having
jurisdiction to all of the system components listed below:
1- Electric and or gas heater (where installed)
1- Filter pump
1- Pump 1 therapy pump
1- Pump 2 therapy pump
1- Propulsion drive assembly
1- Freeze Protect Circuit (where installed)
NOTE: See “Overall Design Information” section for electrical specifications for each model.
The low voltage system interface wiring connecting the timer, emergency shut off, and spa
control must also be installed as per code. Refer to the “Technical Drawings” section of this
manual for suggested layout of timer and emergency shut off.
The conduit termination point should be sealed with a UL Listed sealing device. All wiring must
be routed through approved conduit that is sized for the wire gauge being used. The conduits
shall be terminated using a Liquidtite conduit. GFCI nuisance tripping and motor noise is
reduced when using the metal conduit. In the event that local codes have additional require-
ments they must be followed.
The spa equipment must be grounded by way of a bonding wire in addition to the normal
ground wiring of the electrical components. The use of this bonding wire will reduce nuisance
tripping of the GFCI breaker. The gauge of this bonding wire must be the same gauge as the
live conductor to insure that it is capable of carrying the current in the case of a short circuit.
Wire used must be a minimum of 75 degree centigrade stranded copper rated MTW or THHN.
Solid copper wire of any kind is NOT to be used to GROUND components. Solid copper wire
may be used to BOND metal parts per local code.
The electrical components used to operate this unit should be wired per the component manu-
facturers recommendations. All electrical components shall be protected by a G.F.C.I. The
propulsion controller requires the installation of a special G.F.C.I. which has been supplied with
the spa. All other electrical components shall be supplied by a circuit protected by a G.F.C.I.
and installed in accordance with Local, and State law, and the NEC. In the event that one
requirement is more restrictive, the more restrictive requirement shall be used.
An optional control box can be ordered that allows for most electrical control devices
to be housed in a UL approved box and comprises of all UL approved components. Taking
advantage of this control box will allow for a simple and quick electrical installation. Refer
to the “Technical Drawings” section of this manual for electrical installation schematics
used to wire the system with or without the optional control box.
The optional Control Box is capable of controlling the circulation pump (24 hour continuous),
both therapy pumps, lights (on/off), propulsion system, e-stop, and timer (15 min.).
Before connecting to the spa electrical components, check the incoming power to confirm a
voltage level of 216 – 264 VAC.
Connect bonding connection to the spa bonding lug located on the step entry side of the spa.
Also verify that a bonding connection is made to the bonding block located on the opposite
end of the pa where the propulsion VFD is located. Bonding connection, wiring and installa-
tion shall comply with the NEC and local codes.
