2. THEORY OF OPERATION
A. ACCESS PANEL LOCATION
Access must be provided to perform any service to your
whirlpool. When reading this information, it is a good
idea to open your access panel and familiarize yourself
with the components described below.
After reading this manual, contact your Kohler
dealer if you have any questions.
B. BASIC WHIRLPOOL COMPONENTS
Your new Kohler whirlpool consists of the following
components.
The bath: acts as a reservoir for water and
provides a location for whirlpool action.
The pump actuator: turns the whirlpool on and off
through the activation of a sensing device. This
switch also allows you to regulate the water flow.
The pump-control box: includes the relay and
timer that drive the motor and the pump. This
assembly must be protected with a Class A
Ground-Fault Circuit-Interrupter (GFCI) supplied
by your installer to prevent electrical line-to-ground
shock hazard. Never bypass the GFCI. If the GFCI
trips or the whirlpool is not working properly, call a
Kohler authorized service representative to repair
the problem.
The 2-speed pump motor unit with built-in
heater: provides the power to move the water and
create the soothing whirlpool action. The built-in
heater engages and remains on to maintain water
temperatureas long as the pump is running and the
whirlpool water temperature does not exceed 104
°
F (40
°
C).
Adjustable jets: placed strategically for optimum
hydro-massage. You control the air and water flow
of each jet. The air and water flow is determined by
how far you open up the jet nozzle.
The built-in heater: automatically turns on when
the whirlpool is started, and maintains the water
temperature to a maximum of 104
°
F (40
°
C). The
heating element is built into the pump. The heater
is internally wired, and requires no external
electrical connection.
C. WATER AND AIR FLOW CYCLE
The diagram shows the water and air flow for a typical
Kohler whirlpool bath. Once you fill your whirlpool with
water, it becomes a self-contained system.
Water is drawn from the bath through the water suction
inlet located near the bottom of the bath. The water is
pulled into the pump and circulated past the built-in
heater. The water is then forced back into the bath
through adjustable jets located in the bath walls. Valving
is used to regulate the water flow intensity and/or to
supply water to the neck jets. The suction inlet is
protected with a cover to prevent small objects or hair
from becoming entrapped.
Air is drawn into the stand pipe, mixed with the water
stream at the jets and is adjusted by rotating each
individual jet flange.
The operating cycle continues as long as the pump and
motor are running. A built-in timer automatically shuts off
the pump and motor after 20 minutes of operation.
