Check the electrical connections. Test the outlet for power by plugging in a small lamp or hair dryer. Check to
make sure the breaker is not tripped. Replace GFCI outlet or breaker if necessary.
The condition results from sediment in the water heater of the home. Drain and flush the heater according to
the manufacturer’s instructions, and then clean the interior of the tub with a mild, grease cutting dish soap.
Each MTI Boutique Series air bath is equipped with a pair of sensors near the drain of the bath. They appear
as two small chrome buttons. Every time water is introduced into the bath, even if the air system was not used,
the air system will automatically activate approximately 7 minutes after the water has drained out of the tub in
order to purge the system of any small droplets of water. The system will turn off in approximately 1 minute.
Water soluble products such as bath salts are fine to use, however, MTI does not recommend the use of heavy
bath oils. If bath oil is used, refer to the care and cleaning section of this manual for proper after-care and
cleaning instructions.
Most scratches and scuffs can be easily sanded out. Please contact MTI’s service department for instructions.
Deeper scratches and chips may require the services of a professional repair technician.
To verify, turn the air system on high for 4-5 minutes (you do not need to have water in the tub). Carefully feel
the grey air hose where it exits the blower. It should be warm to the touch. If it is cold, please contact MTI for
service. Please note that some skin sensitive people might experience the so-called “cold air effect”, which is
caused by the actual sensation of air bubbles running along the skin, giving the bather a “shivering” sensation.
Note:
Even if the air entering the tub was hot enough to burn the skin, this shivering effect would still persist.
The heated blower is not designed to heat your bath water, just to pre-heat the incoming air. The air hose and
blower must be installed in a climate controlled environment. Pipe insulation may be used to insulate the air
hose, however, do not insulate the blower itself; the blower needs sufficient air space surrounding it for proper
circulation and operation.
Small, barely detectable power fluctuations may have disrupted the purge cycle. Turn the breaker off (or unplug
the blower), wait for ten seconds, then plug back in. The blower should now follow the normal purge cycle.
The problem is most likely the breaker or the GFCI outlet. Check your breaker box first, and then use a hairdryer
to test the outlet where the equipment is plugged in. This should identify the problem. If both these items check
out fine, please have your serial or registration number available and contact MTI’s service department.
Barely detectable power fluctuations may occasionally disrupt the remote control operation. To correct:
If the remote is still inoperable, please have your serial or registration number available and contact MTI’s
service department. The remote control is a non-serviceable, sealed control, so it cannot be repaired on site.
1.
Turn off the breaker or unplug the blower, then turn it on again.
2.
Within 15 seconds, simultaneously press the “plus” and “minus” buttons, hold down for four seconds, and
release. The remote is now ready for use.
3.
If the synchronization is not successful, simply repeat the steps.
One or more connections may have been unplugged during installation. Check that the grey air hose from the
air blower to the manifold, and from the manifold to the tub, is properly connected. If necessary, reconnect and
tighten clamps. See illustration on page 9.
