Installation Instructions – Airbath
Check Valve And Airline Installation
• The remote check valve MUST be mounted at least 2” above the top rim of the tub. Use 1” PVC flexible pipe or rigid schedule 40 to
connect the remote check valve to the manifold (factory installed underneath the tub) or to the grey air hose at the manifold. Connect
the check valve to the blower using the grey hose. Make sure ring clamps are secure on both end of the grey hose(s).
• NOTE:
Depending on remote check valve location and site conditions, the air hose that is attached to the manifold can remain within
the pedestal or run under the floor to connect to the roughed in airline in the floor, or exit the tub through the side of the pedestal base
for an above-the-floor airline installation. When running grey hose under the floor, use a heat resistant adhesive to secure connection
from hose to pipe and use care not to crush or restrict the airflow in the line in any way.
IMPORTANT:
Side exit from the pedesal would require onsite drilling through the pedestal and should only be considered when there is
no subfloor access to run the airline. MTI does not recommend an above-the-floor airline, unless the tub and outlet in pedestal are very
close the wall or the airline can be concealed with nearby or surrounding cabinetry. Onsite modification to the pedestal is performed at
the risk of the installer. MTI does not pre-drill the pedestal base for side exit

Water Sensor, Remote Control & Keypad Installation
• The water sensor wire, factory installed to posts under the tub on either side of the tub drain
(Photo B)
, will connect to a port on the
side of the blower
(See Illustration A on next page)
. Do not attempt to remove the sensor wires from the tub. To extend this wire, splice
in 18 guage, low voltage wire. Be sure to save the two pin connector to allow connection to the blower.
• Use the 12” ethernet cable to connect the radio receiver module to the blower.
(See Illustration B on next page)
. The keypad comes
synchronized to the blower from the factory. Synchronization instructions are provided with the remote control.
• The keypad is optonal and can be mounted convenient to the bather or in an inconspicuous location to use as a secondary option for
system control. Use the 6’ ethernet cable to connect the keypad to the secondary jack on the radio receiver module

Test
• Plug the blower into the outlet and test for operation. After the airbath is turned off and water drains from the tub, the LED light on the
keypad will flash continuously, indicating the purge cycle is activated.
• NOTE:
All air baths are equipped with an automatic drying cycle. Approximately 7 minutes after the bath is drained, the blower will turn
on for 1-2 minutes. This drying cycle cannot be cancelled. Any attempt to cancel this cycle resets the countdown timer. When the purge
cycle is complete, the LED light will cease flashing.
If your bath came equipped with an air system, there are several considerations and important installation procedures to follow. To
maintain optimal perfomance and easy operation, the following conditions must be met.
