Laurel Mountain - Owner’s Manual
Whirlpool Inline Heater
The inline heater is designed to MAINTAIN the temperature
of the bath water between 101-104 degrees Fahrenheit. These
limits cannot be increased or decreased. The Heater is operated by a
pressure switch which is programmed into the heater. This switch allows the
heater to operate only when there is sufficient water flowing through the system.
This option is equipped with a molded plug on the end of a supply cord. Check your local codes and install a
120VAC 20amp GFCI protected dedicated circuit wall outlet within 1.5’ from the heater unit. Plug the cord into
the outlet. Every time the whirlpool unit is activated, the heater will activate as well, and will MAINTAIN the
water’s temperature between 101-104 F. *Note: The heater has a piggyback outlet that ONLY the mood light
(1 amp) may be plugged into.
Water Heater for Air Bath and Soaker Tubs
The on/off button on the bathtub activates/deactivates the heater. The heater has a built-in 20 minute timer
and is a low flow/high efficiency pump, providing silent operation. The option is equipped with a molded plug
on the end of a power supply cord. Check your local codes. For the LM305 install a 120 VAC 20amp GFCI and
make sure the GFCI protected dedicated circuit wall outlet is located within 1.5’ from the heater unit. Plug the
cord into the outlet. This heater is designed to MAINTAIN the temperature in your bath water between 101-
104 deg Fahrenheit. These temperatures are preset and cannot be adjusted.
Hydrotherapy Back Massage System
Back Massage Functioning - Includes 8 jets that function on an independent 3/4 hp (5.0 amps). 2 jets work at
a time cycling up and down your back. This system requires a 20Amp dedicated circuit, 120V.
Back Massage Controls – DO NOT OPERATE the back massage system before you are in the tub and ready
for use. Doing so will spray water out of your tub! (1) The push button located at the bottom left of the
photo above turns the unit on and off. The large dial (2) on the right will adjust the cycling speed of the jets
from completely stopped on 2 active jets, to quickly cycling up and down through the entire back massage
system.
