SECTION 10: HOW TO TAKE A SAUNA

• When taking a sauna, allow time to relax completely.
• Remove clothing and jewelry…if required, wear a towel loosely.
• After 10 minutes or when perspiration begins, leave sauna and relax in dressing area…follow with a cool shower.
• Cooling time should equal time spent in sauna. Enter sauna room again and stay 5 or 10 minutes.
• Repeat the cycle 2 or 3 times; end with a brisk shower…rinse in cool water.
• Dress when completely dry and perspiration has stopped.
• Some sauna bathers enjoy the soothing effect of steam by splashing water on the heated sauna rocks. Use only one dipper full (approx. ½ cup) at a time and keep clear of the steam as it rises off the rocks.
• Do not smoke, exercise or drink alcoholic beverages in the sauna room.
• Do not pour chlorinated pool or spa water on the heater or corrosion damage may result.

3. In the outer sections, use smaller rocks placed more tightly (see note b).
4. Place rocks loosely in the center section (see note a).
5. Be sure rocks completely cover the elements (see note c).
6. Loosely cover the tops of all elements with rocks a minimum of 2” to 3”.

SECTION 11: WARNING PLACARDS WARNING

Three metal placards are included in the Installation Instruction Envelope packaged with every Sauna Heater. The CAUTION placard must be attached to the interior wall of the sauna room directly above the heater where it is visible to the bather. The WARNING placards must be attached to the door of the sauna room.

SECTION 12: ROOM CONSTRUCTION

• For safety and reliability, the following rules must be addressed.
• No permanent locking or latch system is to be used on the sauna door.
• Acceptable door fittings are: magnetic catches, friction catches, spring or gravity loaded closures.
• The door must always open outwards.
• No shower may be installed in a sauna room.
• No electrical receptacle shall be installed inside the sauna room.
• The enclosed WARNING: Reduce the risk of overheating … warning plate must be mounted on or alongside the door outside the sauna room at about eye level.
• The enclosed CAUTION: Reduce the risk of fire … caution plate must be mounted on the interior wall above the heater.
• The heater should not be operated without ~ts container properly filled with rocks and the rock guard in place.
• If an intercom speaker is installed, it should be away from the heater and as close to the floor as possible.
• Fire sprinkler systems installed inside any sauna room should be properly rated for sauna room temperatures.
• Always mount the heater according to these installation instructions.
• Minimum of R12 insulation in 16″ on center 2×4 stud walls.
• Recommended minimum flooring thickness of 5/8″

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, V³9.3, For R³31, V³0.3R
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.

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 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.

SECTION 14: 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 fioor 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 fioor 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.

DIAGRAM 15

SECTION 15: BWT (Bio Water Technique) Technology

The world sauna trend is moving to the higher humidity and lower temperatures. Many nd 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.

SECTION 16: TROUBLESHOOTING

If control displays “Sn Cold” it means no sensor is connected. Refer to Section 5 for sensor installation information.

If control displays “Pre-Heat” it means no sensor is connected or it means 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 “Sn Cold” if a sensor is not connected.

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 Cycles / ATTENTION: Utilizer uniquement un contactor approve pour 250,000 cycles de fonctionnement
