CILINDRO HEATER INSTALLATION MANUAL |PAGE 3
POSITIONING YOUR HEATER, POWER UNIT, AND TOUCHPAD
You should have received two boxes with all the necessary components for your Cilindro heater. The rst is the heater box itself.
Remove the heater from the box. Next, open the Xenio control box - this box will contain the power unit, the digital touchpad,
hardware, and temperature sensor.
Note: It is possible you will receive two temperature sensors - one in the heater box and one in the Xenio control box. They are the same
sensor - set one aside as a spare for possible later use.
Upon its arrival to you, the Cilindro heater has two adjustable feet pre-installed into its base. In this
state, it can be used in conjunction with the provided mounting bracket, instructions for which
can be found in the manufacturer’s manual. However, when being installed in an Almost Heaven
Sauna, it is recommended that you remove the two additional feet from the provided mounting
bracket replacing them into the vacant holes under the heater. In this way, the heater will be
sitting directly on the oor.
Note: You will need channel-lock pliers to remove and reinstall the feet.
The Cilindro heater is a oor mounted unit. It should sit on a level surface, with feet that can be adjusted to accommodate a slight
gradient. Position the heater in the designated heater location in your sauna.
Due to its height, the top of the Cilindro heater should be anchored to the wall of the sauna. A bracket is provided in the hardware
to achieve this; secure it to the wall and heater following the instructions in the manufacturer’s manual. We recommend anchoring
the heater once all connections have been completed, and prior to placing the stones.
POSITIONING THE HEATER COMPONENTS
Indoor Saunas
For indoor sauna applications, mount the power unit on or near the sauna. It can be mounted on the exterior of the sauna, or on
an adjacent wall. The main power for your heater will connect here rst, and then relay onto your heater. Next, consider where
you’d like to mount your touchpad. You can mount the touchpad wherever it’s most convenient for you. We do not recommend
mounting the touchpad in the sauna itself.
Outdoor Saunas
Neither of these components are waterproof, so proper precautions should be taken for outdoor sauna applications. Please
consider the following:

is mounted in the sauna and connects to the power unit. If the sauna is located greater than this
distance away from where the power unit is installed, then the power unit should be mounted
nearer to the sauna in a weatherproof enclosure with proper ventilation. The image at the left is an
example of an enclosure. Alternatively, you can purchase a longer temperature sensor wire directly
from Almost Heaven Saunas.

CONNECTING YOUR HEATER TO POWER
Please note, the power unit provided with your sauna is rated for single-group connection. The instructions below are for single-
group connections only.
Incoming Power
First, you will need to bring power to your power unit. Remove the power unit’s cover and pry out the appropriate knockouts that
will allow the wiring to enter and exit the unit.
Note: for visual purposes the wiring images you will see in this manual do not utilize the knockouts.
Connect the power cord to the appropriate terminals, with the two hot lines connecting to the left-most L1 and L2 terminals, and
the ground connecting to the ground terminal. A neutral line is not needed - this is only required if a light or ventilation fan is
connected to the power unit, an application that is not available in the U.S. market.
Power Unit Wiring

CILINDRO HEATER INSTALLATION MANUAL |PAGE 5
Outgoing Power
Next, you’ll want to relay power to the heater itself.
Remove the terminal block cover (at the back of the heater), and cut out the center of the rubber
gasket under the heater - this is where the wire will enter the heater to connect to the terminal
block.
Using the same gauge wire you used to bring power to the power unit, connect the left-most
outgoing L1and L2power unit terminals to L11and L21on the heater. Next, connect L11and L12
together with the provided copper jumpers. Do the same with L21and L22. Finally, connect the
ground terminal at the power unit to the ground terminal at the heater.
Now, connect A1 on the power unit to A1 on the heater. Repeat for A2. This completes the high-
limit safety circuit. It is sucient to use a 12 gauge wire for this circuit.
Temperature Sensor
The temperature sensor mounts in your sauna and provides feedback to the power unit regarding the temperature in your sauna.
We advise mounting this sensor approximately 18”to the side of the heater, and approximately 18”below the highest point of the
sauna. Use the provided hardware to mount the sensor.
Next, feed the sensor wire out of your sauna in order to connect to the power unit.
Secure the wiring to the circuit board mini-terminal. Starting on the outside and moving in, the wires should connect in the
following order: blue - white - red - yellow.

Touchpad
The touchpad should be mounted in a dry location. Once you’ve determined this
location, use a athead screwdriver to gently pry the screen of the touchpad from the
mounting bracket. Feed the data cable through the hole in the mounting bracket, and
mount the bracket to the location you selected. Push the data cable connector into the
port on the back of the screen and snap the screen back into the bracket.
Next, connect the other cable to the port closest to the power unit’s mini-terminal block that is connected to the temperature sensor.
Replace the power unit’s cover and turn the power switch on the underside of the power unit to the “on position”.
PLACING THE STONES
We highly recommend wearing gloves when placing the stones.
Depending on the size heater you selected, you should have received 5-7 boxes of stones with
your Cilindro heater - you will not use all of them. Rinse the stones before placing them into the
heater to remove any dust. Once cleaned, place the stones around and on top of the heating
element grates. Do not “play Tetris” with the stones to t as many in the heater as possible - this
will compromise heating eciency. Once you set a base layer of stones in the heater, gently
drop the stones and let them rest where they land. Fill the heater with stones until the top of the
stones are 1 to 2”below the top of the heater.
It is recommended that you remove the stones once a year, replace any that have cracked or
corroded. It is a good idea to rinse these stones at this time, too. You may purchase additional
stones from Almost Heaven Saunas

OPERATING YOUR HEATER
Note: Your touchpad’s default settings are compatible with your heater. No changes
are necessary.
Immediate Start
Turn your breaker on. If everything is connected correctly, the buttons at the bottom of the screen
should illuminate. The bottom left button is the main power unit - press it, and you should hear a
loud “clunk” from the power unit, which is the contactors engaging. If you do nothing, it will begin
heating immediately; the display will show the current temperature in the sauna, as well as the time
remaining on the heat cycle.
Delayed Start
Turn the power button on the touchpad. Press “menu” until the clock icon is ashing. Adjust the
preset time by pressing + or - until you get to the desired preset time. You are able to preset your
heater in 10 minute increments for up to 12 hours. The time remaining before the heater turns on
should appear below the brackets at the top of the touchpad.
Setting the Temperature
The temperature displayed on the screen is the temperature inside the sauna where the temperature sensor is mounted. To set
your desired sauna temperature, press the power button on the touchpad. Press “menu” until the thermometer icon ashes.
Adjust the temperature with the + or - until your desired temperature is displayed. The sauna will heat to and hover around this
temperature.
