The K3 and KT3 controls provide automatic temperature control with AK steam generators. These
controls allow the user to set steam bath time and to adjust the bath operating temperature.
Note: For a temperature controlled steam bath, the AK generator requires either a KT3 with built
in temperature sensor or a K3 with separate temperature sensor. Another K3 may be added to
allow two controls for a steam bath, such as one inside the room and one outside, but if a KT3 is
installed it must be inside the steam room. A maximum of two controls may be installed.
1. Ensure that both the power circuit and water supply to the generator are ON.
2. To activate the steam, press the K3 (or KT3) control's On/Off switch. In 10 to 20 minutes
the room should be comfortable enough to begin taking a steam bath. The unit will turn off
automatically in 30 minutes. Note: other bath times and temperature may be set by the user.
3. Remove clothing and jewelry.
4. Enter the steam room and close the door to prevent steam from escaping.
5. Relax and enjoy the warm steam releasing tense muscles and refreshing the entire body. The
average time spent taking a steam bath is approximately 10 minutes
6. Pressing the control's on/off switch while the steam generator is operating will shut it off.
7. If your steam room has a shower, a pleasant experience can be achieved by taking a warm
shower while in the steam. You will nd the contrast from water to steam quite invigorating.

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 oor, 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 oor. 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.

1. TEMPERATURE SENSOR CABLE ROUGH-IN Required if using only a K3 (KT3 not installed) The low voltage temperature sensor must be mounted in the
steam room if a KT3 will not be used. Do not mount directly over the steam dispersion head or near the door. The sensor should be located in a wall 6” (150 mm)
below the ceiling but no more than 7ft (2,1 m) above the oor. String the sensor cable from the sensor location through 1/2” (12 mm) holes in the wall studs or
ceiling joists to the generator location. Drill a clean 7/8" (22 mm) hole through the steam room wall at the sensor location. Leave 12” (305 mm) of slack at the
sensor location. See Figure 3.
Note: Do not staple through or damage cable. Use factory supplied cables only.
INSTALL THE TEMPERATURE SENSOR ASSEMBLY inside the steam room. A 7/8” (22 mm) hole
should already be in the steam room wall with the cable ready.
a) Carefully connect the sensor cable to the sensor. The cable end should slide into place and lock.
b) Run a light bead of silicone around the back surface of the sensor and slide it into the wall with
the metal sensor tube pointed down. Tape the sensor to the wall until the silicone has set-up.
c) Connect the steam generator end of the cable to the sensor jack on the steamer’s circuit board.
See Figure 5 for the sensor jack location.
2. K3 or KT3 ROUGH-IN The low voltage controls can be mounted up to 25ft (7,6 m) from the
steam generator. The K3 control may be mounted either inside or outside the steam room and
the KT3 must be mounted inside the steam room so its built in temperature sensor will function.
String the 25ft (7,6 m) cable from the control location through 1/2” (13mm) holes in the wall studs
or ceiling joists to the generator. Note: Do not staple through or otherwise damage cable. Use
factory supplied cables only.
Optional for tile rooms: a rough-in box may be installed at the desired control mounting location. A
mounting plate with proper diameter hole and instructions is available. The plate mounts to a
single switch/outlet box and the tiles should be nished over the plate and up to the hole edges
to leave the control’s mounting hole clear. (See Figure 4)
3 INSTALL K3 or KT3 CONTROL The low voltage K3 control can be mounted directly to a nished
wall either inside or outside the steam room. The low voltage KT3 control must be mounted in-
side the steam room. See step 2 above. The control cable should already be roughed-in to this
location.
Use a 1-3/8” (35 mm) hole saw, to drill a hole in the nished wall where the control is to be mount-
ed (the control cable should already be roughed-in to this location). This must be inside the room
for KT3 controls. Plug the cable end into the jack in the back of the control
Run a bead of 100% silicone caulk around the tube on the back of the control. Make sure there is
enough to ll any grout lines and make sure the silicone is far enough from the edges to remain
hidden after mounting to the wall.
Make sure the cable is rmly connected to the control then insert the control’s tube into the mount-
ing hole and rmly press the control against the wall. Level the control and tape it in place
(painter’s tape generally works well), then leave until the silicone is cured.
Route the generator end of the control cable through a knockout in the end of the generator and
secure it using the strain relief provided. Plug the control cable into its socket on the steam gen-
erator's circuit board (See Figure 5).
Note: for steam bath temperature control, a K3 and a wall mounted sensor or a KT3 (with built in
sensor) must be installed. Only one KT3 may be installed. You may combine two K3s or a K3
with a KT3.
4. OPTIONAL SECONDARY CONTROL : As an option, a second K3 control may be installed with a K3 or KT3 to provide controls both inside and outside the
steam room. The second control should be installed as described in above, with the second K3 control cable plugged into the second S60 connector.

SECTION 5: MAINTENANCE OF YOUR AK STEAM GENERATOR
The steam generator, steam head, ttings and plumbing connections should be inspected regularly for water leaks and damage. The AK steam generator is supplied
with a manual drain valve for ushing sediments from the generator tank; an optional automatic electronic drain is available as an option. The autodrain option drains
and rinses the bath after each use. If only a manual drain is available, the steam generator should be manually drained periodically following the Flushing Procedure
shown here. This procedure should be scheduled monthly or more often depending on local water conditions and steam bath usage.
Flushing Procedure: The generator should be cool before starting.
1. Use the control to start a bath. Immediately go to the generator and open the manual drain (open is with the handle in line with the drain pipe, closed has the
handle pointing straight out over the side of the pipe).
2. Allow the tank to drain for a couple minutes then close the drain and allow the tank to ll for about 1 minute.
3. Open the drain again and allow the water to run with the drain open for a full 10 minutes with the bath turned on.
4. Use the control to turn the bath off then go to the generator. When the water stops owing out the drain, close the manual drain valve.
