WARNING: When installing or using electrical products, basic precautions should always be
followed, including:
1. All MTI BASICS walk-in tubs equipped with a whirlpool or air bath require a separate 15 amp 110
VAC circuit for each 5.9 amp pump or blower. Radiance
®
tub shell heating system adds 5 amps.
The inline heater for whirlpools adds 5.3 amps. The inline heater for soakers (HTISOAK) will
require an additional 15 amp circuit. 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 electrician before using.
2. Each whirlpool pump, air blower and inline heater is supplied with a 29” grounded plug which
should be plugged into a standard grounded receptacle. Do not remove this plug. If a wall mount
switch is desired to control use of the unit, the switch should control the receptacle. Under no
circumstance should you alter the provided supply cord.
3.
A pressure wire connector is supplied on the exterior 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. NOTE: air blowers do not have any exposed metal and, therefore, do not
require a bonding conductor.
