GENERAL INSTALLATION GUIDELINES Specific air bath installation instructions are on page 6. Do not begin building any structure for your tub until your tub arrives. All printed specifications for MTI tubs have +/- ½" tolerance AND ARE SUBJECT TO CHANGE AT ANY TIME. Take all final installation dimensions from your tub. Note: air baths, the pre-leveled foam base and pre-leveled frame add approximately 2-3 inches to the height of the tub.
AIR BATH INSTALLATION INSTRUCTIONS Do not attempt to remove the foam or board from the bottom of the tub. Doing so may cause damage and will void the warranty. Do not remove the wires attached to the sensors located on each side of the drain. 1. Never handle the bath by the blower, piping or other equipment. 2. Make sure the manifold and airlines are protected when moving the tub into the house. 3. An access panel of at least 16" x 14" must be provided for the blower for any future servicing. 4.
OPTIONAL EQUIPMENT INSTALLATION GUIDELINES THE OPTIONS BELOW ARE NOT STANDARD ON EVERY BATH. PLEASE CHECK YOUR ORDER FOR ANY ADDITIONAL OPTIONS ADDED. INLINE HEATER OPTIONS: HTI - The heater has a separate power cord that must be plugged into a 110 VAC,15 AMP, GFCI protected outlet. There is an indicator light on the heater to check for operation.

OPTIONAL EQUIPMENT INSTALLATION GUIDELINES (continued) CLEANING SYSTEMS FILL-FLUSH® CLEANING SYSTEM If your unit arrived with pre-installed valves, simply connect the hot and cold water lines to the valves. The tub will fill through the jets, eliminating the need for a filler spout. If the unit was purchased with the Fill-Flush System with no valves installed (“stub-out”), you must first install the hot and cold valves either on tub or in decking surrounding tub.
VIRTUAL SPOUT Incoming water is connected to mixing valves mounted on the tub, surrounding deck or wall. Output from the mixing valves must then be tied into either a Wilkins Double-check Valve or Atmospheric Vent Valve, depending on local backflow prevention plumbing codes. If code requires an Atmospheric Vent Valve, you can use either a tub mounted or deck mounted Breda Valve or an In-wall Acme Valve. Output from any of these valves is then connected to the Virtual Spout.
OPTIONAL FEATURES INSTALLATION GUIDELINES (continued) STREAM BATH INSTALLATION / OPERATION INSTRUCTIONS Prior to installation, this bath must be water tested in accordance with the procedures outlined on page 2. The tub will then be installed following the instructions starting on page 3. Keypad functions for Stream Bath with Air System (no LED lights) can be found on page 12.

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.
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.
