SECTION 2: OVERVIEW
SECTION 3: SETTING BATH TIME AND TEMPERATURE
The K3 and KT3 steam generator controls feature adjustable bath time and temperature controls with a
digital display. The actual room temperature and time remaining are alternately displayed every 5 seconds.
The display also indicates error codes, if needed.
• The temperature can be adjusted from 84 to 125 °F (29 to 52°C) with an initial default of 120 °F (49°C).
The temperature display preference may be set using a jumper on the steamer circuit board to select either
°F (default) or °C.
• The maximum bath time may set to 60 minutes (default) or 24 hours (for light commercial use) using a
jumper on the steamer circuit board.
If a KT3 is installed
: The KT3 control must be mounted inside the steam room, approximately 4 feet up
from the floor, as it contains the temperature sensor. A K3 control may be installed outside the steam room
as a second control. Either control my be used to control the steam bath.
If a K3 is installed
without
a KT3
:
The K3 control may be mounted inside or outside the steam room, approximately 4 feet up from the floor. A second K3 control
may be installed so one is inside and the other outside the steam room. Either control my be used to control the steam bath. Note:
when a K3 controls the steam
bath without a KT3 installed, a separate temperature sensor must be installed in the steam room.
During a steam bath
: The ''sequential steam'' feature automatically changes heating levels depending on how close the room temperature is to the set point.
When very close to the set point, heating is cut back to about 30% full power so the temperature remains more constant during use. If the temperature drops a
few degrees, the heating goes up to about 60% of full power and if the temperature drops more full power is applied until the room heats enough to start reducing
power again.
The K3 and KT3 controls operate identically
.
Bath Time
: The default bath time is 30 minutes, adjustable from 5 to 60 minutes in 5 minute increments. A jumper on the steamer board may be set for a bath time
settable up to 24 hours max. in 1 hour increments. To check the time setting, turn on the steam bath then press the TIME switch. The set time will immediately be
displayed. Continue holding the switch for 5 seconds and the setting will begin to change. Continue pressing the switch and the TIME setting will step up until the
highest set point is reached then step down to the lowest, then step up again. Release the TIME switch once the desired setting is reached. Whenever the TIME
switch is pressed for more than 5 seconds, it will change to set mode and start to increase.
Bath Temperature
: The default bath temperature is 120°F (49 °C), adjustable from 84 to 125 °F (29 to 52°C), adjustable in 1° increments. A jumper on the steamer
board may be set to provide either a °F (default) or °C temperature display. To check the temperature setting, turn on the steam bath then press the TEMP switch.
The set temperature will immediately be displayed. Continue holding the switch for 5 seconds and the setting will begin to change. Continue pressing the switch
and the TEMP setting will step up until the highest set point is reached then step down to the lowest, then step up again. Release the TEMP switch once the desired
setting is reached. Whenever the TEMP switch is pressed for more than 5 seconds, it will change to set mode and start to increase.
Settings
will be kept until manually changed or until power is lost to the steam generator.
If power is lost, the settings will return to factory defaults but the
60 min/24 hr and °F/°C choices will not change unless their jumpers are moved on the circuit board.
The jumpers for newer model AKs (built since March, 2017) are shown in Figure 2A, below. This model has its circuit board mounted on the back of the steamer.
The jumpers for older model AKs (built before March, 2017) are shown in Figure 2B, below. This model has the steamer circuit board mounted on the steamer shelf.
