Always protect tub from construction damage by using a protective cover. Damage, including
chips and scratches, incurred at the jobsite is excluded from warranty, but may be repaired by
qualied technician at the owner’s expense. Do not stand in the tub or store materials in the tub
during construction. Do not store tub in temperatures below 32 degrees Fahrenheit. Proper waste and
overow installation is the responsibility of the installer. MTI does not warrant leaks associated with im-
proper waste and overow installation.
There are many possible ways to install your new MTI tub, and some may require different framing than
the following instructions. Keep in mind that the framing should always provide a level surface for the rim of
the tub and sufcient space below the tub for bedding compound. Access must be provided to each pump,
or electrical component on your tub. The access panels must have a minimum size of 16" x 14" for
installation and future servicing of the equipment. MTI will not authorize any service unless clear
access is available. The installer is responsible for providing access for any future servicing. The
bolts/screws through the mounting feet on the pump may be loosened or removed once the tub is
in place if necessary for future servicing.
Each MTI tub may be ordered with a wide array of options. If your tub has more than two power cords, the
power cords will be gathered together with a bright yellow hang tag to indicate the number of power cords to
be plugged in for proper operation. See electrical specications on page 4.
Additional access to plumbing xtures is strongly recommended. It is the responsibility of the installer to comply with
local plumbing codes regarding pump and plumbing access. Note: Do not allow any material such as insulation
within 8" of pump. Pump must have sufcient air space surrounding it for circulation.
ELECTRICAL INSTALLATION INSTRUCTIONS
Warning - When installing or using electrical products, basic precautions should always
be followed, including:
1. Soaking tubs equipped with an in-line heater require dedicated 110V circuits for the electrical
components. Please see Electrical Specifications on page 4. If your tub has more than two power
cords, the power cords will be gathered together with a hang tag indicating how many items must
be plugged in for proper operation. This circuit must be connected to a supply that is protected
by a ground fault circuit interrupter (GFCI). Such a GFCI should be provided by the installer
and tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt
power. Push the reset button. Power should be restored. If the GFCI fails to operate in this
manner, there is a ground current flowing, indicating the possibility of electric shock. Do not use
this unit. Disconnect the unit and have the problem corrected by a qualified service representative
before using.
2. MTI pumps and inline heaters are supplied with a 29" grounded plug to be plugged into a
grounded recepticle. Do not remove this plug. The control(s) for various options are typically
located on the tub, and a wall switch is not necessary. Under no circumstance should you alter
the provided supply cord.
3. A pressure wire connector is supplied on the exteror of the pump to permit connection of a
No.8AWG (8.4mm) solid copper bonding conductor* between this unit and all other electrical
equipment and exposed metal in the vicinity as needed to comply with local requirements.
WARNING: Unauthorized modification may cause unsafe operation and poor performance of the whirl-
pool. Do not relocate the whirlpool pump, or make other modifications to the whirlpool system, as this
could adversely affect the performance and safe operation of the whirlpool. MTI shall not be liable under
its warranty or otherwise for personal injury or damage caused by any such unauthorized modification.
