remote installation of air blower and system components

Radiance® ........................................................................................ 1-3 AMP
Bluetooth Amp (Stereo HO w/ Bluetooth) ..............................15 AMP
Due to limited space between the tub walls, remote placement of the blower and some therapy system components is
necessary. These components may be safely remote located while maintaining optimal performance and easy operation
when the following conditions are met.
• Place the blower within 8’ of the tub to reduce heat loss.
• The blower, control boxes, and electrical outlet must be accessible for future servicing.
• Installation location of these components must be properly ventilated to keep components from overheating and
climate controlled to avoid the impact of cold ambient air on the performance of the blower and guard against
humidity that can be corrosive to electronics.
• The blower requires approximately 2 ft of space and a 1” x 4” vent for proper circulation. Do not use insulation within
8” of the blower, and never wrap insulation around the blower as this will cause the equipment to fail.
• There must be a GFCI electrical outlet on a 110 VAC at the recommended size for the air system and options selected
for your tub within 2ft of the blower. See electrical requirements above and your order details.
• A keypad (on/off device) installed remote of the tub must always be connected with one continuous cable. Never
use a spliced or coupled data cable. MTI can provide a data cable up to a 12’ length. Cables in excess of 12’ may be
acquired from local electronics suppliers.
IMPORTANT: Before fishing cables and completing installation, always test the cable with the system components.
Instructions for system operation are on pages 11-14. MTI is not repsponsible for system failures due to the use of parts that
are not supplied by MTI Baths.
The best location for the air blower is directly below the tub between the floor joists. This location keeps the air blower
close to the tub and often offers easy access from below. If the room below has a finished ceiling, there are many fixtures,
such as HVAC cold air returns, that can be used to camouflage the access panel in the ceiling and vent the space. If
access below the tub cannot be made available in your home, there are several other locations where the blower can be
located, such as an adjacent closet or vanity.
TIP: To reduce heat loss, use rigid 1” PVC when extending the airline from the tub to the blower location, and wrap the
PVC in pipe insulation. MTI offers blower boxes, in various styles and finishes, to house the blower near the tub. Find these
bathroom accessories and more at www.mtibaths.com.
EXTENSIONS: A blower extension kit and extension cables for LED lights, Radiance®, and keypads are available. Contact
our Technical Service Department at 800-783-8827or email [e-mail]. If the drain sensor wire needs to be
lengthened, you may splice in 18 gauge, low voltage wire. Be sure to save the two pin connector to allow reconnection to
the blower!
IMPORTANT!
Do not splice cables to extend. Read instructions
below and contact mti baths for cable extensions.
