SECTION 13: VENTILATION

VENTILATION In a private sauna, the air should be changed about 6 times an hour. This can be achieved by making a vent opening (fresh air inlet) in the sauna wall directly below the heater. The air outlet must be lower than the upper  benches, as far as possible from the heater and about two feet higher than the fresh air inlet vent, See Diagram 12. It is recommended that ventilation openings meet the requirements of UL Specification 875. The minimum opening  should be determined using one of the following formulas:
For R<31, V>9.3,
For R>31, V>0.3R
where
R = the floor area of the room in square feet and
V = the minimum vent size in square inches

WARNING
The “CAUTION” and “WARNING” placards must be mounted in accordance with Section 10.
WARNING
REDUCE THE RISK OF OVERHEATING
Exit immediately if uncomfortable, dizzy, or sleepy. Staying too long in a sauna is capable of causing overheating.
Supervise children at all times.
Check with a doctor before use if pregnant, in poor health, or under medical care.
Breathing heated air in conjunction with consumption of alcohol, drugs, or medication is capable of causing unconsciousness.
CAUTION
REDUCE THE RISK OF FIRE
Do Not Place Combustible Material On The Heater At Any Time.
For safety purpose sauna door must open out and not lock.
Never use a wood stain, seal or preservative on the inside of your sauna room.
Light fixtures get very hot during operation. Locate light fixture where it will not be a burn hazard.

DIAGRAM 14: ROOM TEMPERATURES

Non-Typical Ceiling Height
Notes:
Temperatures vary in a sauna room by height and distance from heater.
Ventilation will help reduce it but will not eliminate temperature variations.
The hottest part of the room is always at the ceiling directly above the sauna heater and should not exceed 194°F (90°C).
Air temperature will be 15F to 25°F lower on the opposite side of the room from the heater close to the ceiling.
The temperatures in the elevated view are gen­ eral numbers. Each sauna room is different due to construction variations and ventilation.

SECTION 14: BWT (Bio Water Technique) Technology

The world sauna trend is moving to the higher humidity and lower temperatures. Many find it easier to breathe, the skin feels warm, and the humidity helps induce a sweat. This system will increase the humidity in the room allowing the  air temperature to be lower, and still feel hot.  BWT technology provides the ability to increase humidity levels in the sauna room while the heater is warming up and during the sauna session. The continuous soft boil of water during the  sauna session increases the humidity in the room to provide a consistent feel. Additional water can be added to the rocks to provide an additional spike of humidity as needed. How to use BWT: Allow heater to warm up for approximately  20 minutes and add water into the tank through the side of
fragrance diffuser with slots. Add approximately 2 cups of fresh water into the tank. Do Not Use Pool or Spa Water. Fragrance oils can be placed in the side of the fragrance diffuser without the slots. Avoid adding fragrances directly into the water of the BWT. The oils may cause the water to foam and maybe difficult to remove the scent from the tank.
BWT tank and sleeve should always be installed in heater with rocks. Water in the tank is optional and not required if preference is lower humidity.

SECTION 15: MAINTENANCE

Inspect sauna room at the end of each day the room to ensure the control and system is off.
The sauna, like a bathroom, should be kept clean and odor free. Towels or mats should always be used on benches and floor as perspiration otherwise penetrates the soft wood. To clean and remove perspiration stains, use soap or detergent in warm water, best applied with a scrub brush. Badly soiled surfaces may require sanding. Sand paper wrapped around a wooden block works well.
Air out the sauna often by keeping the door and vents open when the sauna is not in use. Saunas that are in daily use should be washed down at least once a week to keep them clean and the air fresh. Duckboard should be removed from the sauna, the sauna floor mopped and dried in a conventional manner, and the duckboard thoroughly scrubbed and dried before returning to the sauna room. The sauna heater should be wiped down occasionally with a damp cloth to remove lint and dust. The rocks should be removed once a year for cleaning and small or crumbled rocks replaced.
Benches and supporting structure must be inspected annually for potential deterioration due to age, dry rot or abuse.
Any boards with signs of deteriorations should be replaced immediately to avoid possible injury.

SECTION 16: TROUBLESHOOTING

If control displays “Sn” it means no sensor is connected. Refer to Section 5 for sensor installation information.
If control displays “HL” it means the high limit is open. Refer to Section 9 for high limit information.
System won’t start to heat, ensure the system is not in the delay mode. If “dLAY” is flashing in the display window, the system is in the delay mode.
If control displays “JP” it means the jumper is open on the main board in the CB Box. Verify jumper is installed in CN6 location on the main board. If it is open, close the two pins.
If control acts erratically or buttons turn on and off by itself during startup. Turn power off at the circuit breaker, place the glass on the control and turn power back on the system. The control will automatically reset the sensitivity of the  capacitive switches.
CAUTION: Use only a contactor approved for 250,000 endurance Cylces.
