COMPLETING INSTALLATION WITH ACCESS FROM BELOW - recommended method
6. Apply a 3/8" bead of construction adhesive or clear silicone to the bottom of the tub to adhere
it to the floor and carefully lower the tub so the drain drops through the floor. The size of the
cutout in the floor must allow for the entire drain to clear.
7. Use care not to allow silicone to get on the outside wall of the tub or surrounding floor area.
Wipe any excess immediately with a soft, damp cloth.
8. From below, connect the drain to the P-trap.
9. Re-install the access panel using the screws and screw caps saved from step 3.
10. Water test to ensure bath is leak free. Allow 24 hours before use.
COMPLETING INSTALLATION WITHOUT ACCESS FROM BELOW
6. Use two 2x4s to elevate the tub above the floor and align the drain with the P-trap. DO NOT
LET THE TUB REST ON THE DRAIN PLUMBING.
7. Apply a 3/8" bead of clear silicone to the underside of the tub to adhere it to the floor. Use
care not to allow silicone to get on the outside wall of the tub or surrounding floor area.
Wipe off any excess immediately with a soft, damp cloth.
8. Carefully remove the 2x4 supports and lower the tub so the drain drops into the P-trap adapter.
Secure the adapter and re-install the access cover using the screws and screw covers saved from
step 3 on previous page.
9. Water test to ensure bath is leak free. Allow 24 hours before use.

Warning:
When installing or using electrical products, basic precautions should always be followed, including:
1. All MTI BASICS whirlpool and air baths require a separate 15 amp 110VAC circuit for each
pump or air system blower. The inline heater for whirlpools adds 5.3 amps. The inline heater
for air baths and soakers (HTISOAK) will require an additional 20 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, indi-
cating 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. Every MTI BASICS whirlpool or air bath is supplied with a 29" grounded plug on each pump,
inline heater or air blower to 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 require a bonding conductor.
