Steamist Built-In Timer Controls
SMS-45, SMS-60 and SMS-80 Models
The SMS-45, SMS-60, and SMS-80 model sauna heaters are supplied with a dual-function timer that allows the user to "pre-set" the the timer up to 8 hours in advance. The timer has a 60 minute time cycle (the large print "0" and "1" on the dial). If you wish to use the full 60 minute time cycle, turn the timer knob clockwise past the "1" setting on the dial. Then turn counter-clockwise until a "click" is heard. This indicates that the timer is now engaged. The sauna will now operate for 60 minutes and shut off automatically.
NOTE: If the time is set past the "1" on the dial, the sauna heater will not come on until the timer counts down to the 1 hour mark Please note that this is a motorized timer and does not make a ticking sound.
Allow your sauna heater at least 30 minutes to heat up the room to the desired temperature.
The timer has the added feature of advance settings of up to
8 hours. To use the advance setting feature, turn the timer counter-clockwise until you reach the small numbers 1-8.
Set the time clock to the desired advance program. The
Dual Function Timer
amperage. See Figures 1-5 for the required clearances. Any wiring within the sauna walls must be rated for 90°C and all copper wire must be used. Run wire through flex conduit from the wall to the heater and connect to the junction box at the back of the heater with a 90 degree connector. Remove cover plate from junction box and connect supply wires to terminals marked 1 and 2. Connect ground wire to lug marked ground.
If connection to the heater will be made at a later time, bring flex conduit into the sauna room 4 to 6 inches from the floor and leave about 3 feet of flex conduit for connection to the heater. See page 7 for specific instructions regarding the washing and placement of stones as well as heater operation.
sauna heater will begin the countdown to the 60 minute heat cycle. For example - if you want your heater to begin heating in 3 hours, just turn the knob counter-clockwise until the small 3 is reached. Your sauna will be ready for use in approximately 3 1/2 hours (allowing for a 30 minute heat up time).
Thermostat Conrol
The SMS-45, SMS-60, and SMS-80 sauna heaters also come equipped with a thermoastat control. Most sauna bathers will need to experiment with the thermostat control for the first few sessions in order to determine the most suitable temperature. For the initial heat up cycle, set the thermostat at it's maximum setting. Observe the temperature within the sauna, as indicated by a separate sauna thermometer (available separately from your Steamist sauna dealer). Allow the heater 30 minutes to heat the room. If the room is too hot, just turn the knob counter-clockwise and allow the room to cool to the temperature you desire. It may take a few adjustments to reach the optimal sauna temperature.

Placement of the Sauna Rocks
Do not operate the sauna heater without the stones. Use only the stones that are supplied with the sauna heater.
Wash stones with water and place them inside of the heater so that the rocks are between and around the heating elements. Take care, however, not to force the rocks between the elements. Use smaller stones first and continue to fill the heater with larger stones until they are about 2" below the rock guard. You may not need all of the stone.
STONES SHOULD BE PLACED LOOSELY WITHIN THE
HEATER SO THAT THERE IS AMPLE HEAT CIRCULA-
TION AROUND THEM. STONES SHOULD ALSO COVER
THE HEATING ELEMENTS COMPLETELY!
POURING WATER DIRECTLY ON EXPOSED ELEMENTS
COULD GREATLY DECREASE THE LIFE OF THE
ELEMENTS!
Testing of the Sauna Heater
1) After the sauna heater has been wired according to the appropriate wiring diagram as well as local and national codes, turn the sauna breaker on at the main panel.
Make sure that the circuit breaker for the sauna is labeled.
2) Turn the thermostatic control to the "ON" position. The thermostat control is located either on the sauna heater or the remote wall control. If you have a wall control, the indicator light will come on, indicating that the sauna is heating.
Set the timer for 15 minutes.
3) Within 5 minutes, you should be able to feel heat from the heating elements when holding your hand over the heater.
4) If the sauna does not heat, refer to the troubleshooting information listed below.
5) It is normal for a small amount of smoke to appear during the first heating, as a protective element coating needs to burn off. Turn the sauna on for 1 hour prior to using for the first time, to eliminate smoking and ensure the consistency of the sauna rocks.
Troubleshooting
A. If the sauna does not operate after initial installation and wiring:
1) Check to be sure that the breaker is on. ALso, make sure that the breaker is the correct size.
2) Make sure that the neutral wire has been included. A neutral wire is necessary for all heaters except thise with a built in control.
3) Check the circuit breaker in the contactor to make sure that it has not been shorted out.
4) Be sure that the thermostat and timer are in the "ON" position.
5) Check the timer to make sure that it winds down. If the timer has been shorted out, the heater will not operate.
B. If the heater has been in operation, but ceases to operate:
1) Check the circuit breaker to make sure it is on.
2) Check the timer to see if it winds down.
11/10
- 6 -
3) Check the high limit reset button. The high limit reset is located under the heater on the wall mount models and on the back of the junction box on the floor models.
4) Call your electrician or local service peron for additional help.
NOTE! A ground fault interrupter (GFI) should not be installed in and does not belong in a Sauna. If used, the breaker will trip, and damage could result.
C. If Sauna Heater operates, but sauna room does not reach desired temperature (160-185F is considered normal sauna temperature).
1) Make sure you allow at least 30 minutes heat up time.
2) Make sure that the sauna thermometer is located 6 inches down from the ceiling and is located close to the heater. Temperature readings will vary according to placement of the thermometer.
3) Check for the proper wire size and type as specified in this manual.
4) Check placement of the stones in the heater. Stones should be placed loosely around the elements, to ensure adequate air flow.
5) Check for heat loss within the room. Gaps around door openings, excessive use of glass in windows, etc.
6) Is the room properly insulated?
7) Is the ceiling higher than 7 feet?
8) After checking all of the above, remove the rocks and visually inspect the heater elements for holes or burned areas.
CAUTION! Electrician or Service Person.
1) Before servicing, turn power off at the breaker!
2) Make sure all wiring connections are secure.
3) Check for burned spots or shorts in wiring of timer or thermostat.
NOTE: Warranty is void on Steamist heaters and controls if the installer or electrician fails to follow the necessary wiring information as provided in the wiring diagram or fails to follow any and all applicable codes pertaining to the installation of this product.
High Limit Control
Each heater is equipped with a high limit control switch as a safety device. If an abnormal heating condition should occur, the heater will automatically shut off. The high limit switch will need to be reset manually before the heater will operate. To reset the high limit, locate the reset button
(bottom front on wall models, behind the junction box at the back bottom on the floor models) and push upward until the contactor engages. If the reset button continues to trip, contact a qualified service person. Be sure that a GFI has not been install on the sauna heater and sauna control circuits.

Do not place any combustible material on or over the sauna heater. At no time should towels, bathing suits, buckets, or ladles or any other flammable material be placed on or over the heater.
11/10 - 7 -
Use only clean tap water on the sauna stones. Do not use any chemically treated water (such as spa or pool water) on the heater at an time. Use of chemically treated water can result in rapid oxidation of the heater components, voiding warranty.
Maintenance Instructions
1) Use only clean water on the sauna stones. Do not use any chemically treated water (such as spa or pool water) on the heater as it will cause rapid oxidation of the internal heater components.
2) Clean water should always be used in sauna buckets and water should be dumped out after every use.
Scour buckets and ladles occasionally when film collects from usage. Use plastic bucket liner in bucket to prevent leakage.
3) Scrub benches with a soft brush, using soap and water or a mild disinfectant when needed. Typical maintenance in a commercial application is about once a week. Each sauna bather should sit or lie on a towel when taking a sauna, to aid in prolonging the life of the benches.
4) Remove Super Dek or duckboard flooring and wash with disinfectant. On wooden duckboards, test disinfectant on a small area to ensure that there is no chemical reaction that may discolor the wood. Hose off Super
Dek or duckboard and replace in sauna.
5) To maintain appearance of the sauna heater, remove water stains by wiping with a damp cloth occasionally.
6) Steamist sauna heaters require no special maintenance when properly installed by a qualified electrical contractor. After about 1 year of use, inspect the stones to determine if they need replacement. Rocks may crack or crumble over time.
7) Steamist strongly recommends that the sauna floor is made of a material that is easily cleaned. Ceramic tile, concrete, marble, sheet vinyl, etc. are all suitable for use in a sauna. When the sauna floor is made of a non-porous material, it is easy to keep clean, sanitary and odor free. Carpeting is not recommended for use in a sauna.
8) A floor drain should be provided in a commercial application for sanitary cleaning and maintenance.
9) To remove perspiration stains from he walls and benches, the wood may be lightly sanded with fine sand paper to restore its appearance. We do not recommend that stains or sealers be used in the sauna, as they may produce toxic vapors.
10) The sauna room will heat faster if the high vent is kept in the closed position during the initial heat up period.
The low vent may always be kept in the open position.
11) Required warning signs should always be posted according to the instructions.
