SECTION 12: VENTILATION

VENTILATION Ventilation shall be provided in a 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 9.

The minimum opening should be determined using one of the following formulas:

For R < 31, V ≥9.4
For R ≥ 31, V ≥ 0.3R

R = the floor area of the room in square feet
V = the minimum vent size in square inches

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.

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 15°F 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 general numbers. Each sauna room is different due to construction variations and ventilation.

Typical Ceiling Height

SECTION 13: 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.

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.

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.

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 14: TROUBLESHOOTING

If control displays “Pre-Heat’ it means there is no sensor connected to the CB Box or the room temperature is below 10°F. Refer to Section 5 for sensor installation information. Note: the system will heat for 5 minutes and then turn off and error “No Sensor” if a sensor is not connected to CN 4.

If control displays “HL” it means the high limit is open. Refer to Section 9 for high limit information how to reset the device. If the heater continues to have the high limit issue, check placement of sensor for correct location.

If the control displays “Door Open” check to see if the there is a connector on CN 10.

System wont 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 acts erratically or buttons turn on and off by itself during startup. Turn power off at the 120 Volt circuit breaker for control power, place the glass on the control and turn power back on the system. The control will automatically reset the sensitivity of the capacitive switches. Turn power back on and test.

CAUTION: Use only a contactor approved for 250,000 endurance Cylces
