TROUBLESHOOTING
Q: The pump or blower will not turn on. What should I check first?
A: 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. On systems with multiple control boxes or equipment, ensure that
all connections are intact.
Q: There is a leak at the pump when it’s turned on. How do we stop the leak?
A: Check the rubber “O” rings for proper seating. Tighten the large union nut rings on the pump. These may have loosened during
shipping or installation. Do not over tighten.
Q: There is a rust colored, greasy ring in my bath tub. What causes this?
A: 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.
Q: The air jets on my tub are not blowing air bubbles. What could be the problem?
A: The keypad or other connections may have been unplugged during installation. Check that the keypad is connected to the blower,
and the blower is plugged into a working receptacle. Check that the grey air hose from the air blower to the manifold is properly
connected. If necessary, reconnect and tighten clamps.
Q: My MTI air bath appears to just turn on even if we are not in the tub.
A: Each MTI Designer Collection 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 o in approximately 1 ½ minutes. The light on your keypad blinks during the countdown to the purge cycle.
Q: I understand the purge cycle, however my tub is now purging in the middle of the night. How can I stop this from happening?
A: Small, barely detectable power fluctuations may have disrupted the purge cycle. Turn the breaker o (or unplug the blower), wait for
ten seconds, then plug back in. The blower should now follow the normal purge cycle.
Q: The air bubbles seem cool. How do I check that the blower is warming the air?
A: 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 eect”, 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 eect would still per-
sist. The heated blower is not designed to heat your bath water, just to preheat the incoming air. If your tub is installed against an outside
wall(s), it is recommended to adequately insulate the wall(s) to minimize heat loss. Do not insulate the blower itself; the blower needs
sucient air space surrounding it for proper circulation and operation.
Q: Can I relocate the pump and/or blower?
A: Because all MTI tubs are built to order, the pump and blower can be relocated during the manufacturing process (at no additional
charge) to accommodate your specific installation. The pump cannot be relocated once the tub is built. The air blower can be relocated
onsite up to eight feet away from the bath.
Q: Is it safe to use bath salts or bath oils in my air bath?
A: 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 cleaning section of your manual for proper after care and cleaning instructions. Products containing strong natural or
chemical dyes may discolor the jets and/or controls on your tub. Check the label to ensure the products are safe for acrylic or plastics,
and always use according to the product recommendations.
Q: How can I get scratches out of my acrylic tub?
A: Most scratches can be bued out using an automotive polish. Any polish suitable for use on “clear coated” automobile paint is fine.
Deeper scratches and chips may require the services of a professional acrylic repair technician.
Q: My bath’s hydrotherapy system has been working great for years, and now has stopped working. What should I check first?
A: The problem is most likely the breaker or the GFCI outlet under the tub. Check your breaker box first, and then use a hairdryer to test
the outlet under your bath where the equipment is plugged in. This should identify the problem. If both these items check out fine, please
have your registration number available and contact our technical service department.
Q: How do I find the serial or registration number on my bath?
A: The registration number can be found on a silver sticker attached to the outside wall of your bath. It is typically placed 3-4 inches over
the pump and /or air blower.
