TYPICAL WORK INVOLVED FOR INSTALLATION OF MASTER SPAS SPA

Should the mechanical area be enclosed care must be taken to maintain an ambient tempera-

ture that is typical for enclosed mechanical rooms containing pool equipment. The equipment

list below can be used to help determine the correct HVAC requirements during the design

stages. This is a recommended list of standard and optional equipment in a typical spa instal-

lation:

1- Electric or gas heater

1- 1.5 hp ﬁlter pump

1- 1.5 hp therapy pump

1- 2.0 hp therapy pump

1- 50 amp (40 amp maximum ampacity) propulsion drive assembly

GENERAL CONTRACTOR INSTALLATION

The spa room and mechanical area are to be constructed as per the owners design and follow-

ing the guidelines set forth by local codes and the Master Spas Installation Guide.

All shipping and delivery fees are the responsibility of the owner, unless otherwise speciﬁed.

An opening in the building large enough to accommodate the spa will have to be planned

for. See “Overall Design Information” section for dimensional speciﬁcations. The minimum

path dimensions for the spa from the unloading site to the spa area should be approximately

10 feet wide by 6 feet 8 inches high (a site survey should be conducted and good judgement

decisions should be made prior to installation day to prevent delays in the completion date due

to space limitations). The spa is supported by its own steel frame and should remain upright to

avoid damage to the acrylic shell. In the event that the spa would have to be set into a differ-

ent position so as to allow entry, care must be taken to insure that no damage is done to the

acrylic shell or supporting metal frame work.

Once the spa has been moved to the designated area it must be set on the previously con-

structed structural ﬂoor area. If the unit is to be recessed below the spa room ﬂoor, rigging will

be needed to set it properly.

The acrylic on the spa should be protected during the construction process at all times. A tem-

porary platform constructed of plywood and ﬂoor joists covered with a tarp is recommended.

This will keep construction debris from accumulating in the spa and mechanical areas. Never

use clear materials to protect the spa shell. Any damage caused by the use of clear protective

materials, will not be covered by the warranty.

An electrical conduit chase running from the spa to the control area will be needed. This con-

duit should be sized appropriately to allow for the e-stop and VFD power cables to be routed.

Once the electrical and plumbing phases are completed, the spa will need to be cleaned, ﬁlled

and the operation sequence started.

See “Speciﬁcations for Spa Room Area” in this section for information regarding ADA Compli-

ant lift chair installation.

ELECTRICAL CONTRACTOR INSTALLATION

The spa comes with its own GFCI breaker and must be wired according to the wiring diagram

supplied in the drawings section. This GFCI is a special device that is unique to this spa. This

special GFCI is designed to protect the patented propulsion system drive only. It must be wired

directly to the incoming electrical service. DO NOT install a separate GFCI breaker on this
