SECTION 7: HIGH LIMIT CONTROL (RESET BUTTON)

The sauna heater has a built-in high limit control, which automatically turns off the heater if the temperature inside in the sauna room rises to an abnormally high level.

To restart the heater, let the heater cool and turn the timer down to off, then push the reset button on the bottom of the heater, See the last drawing on Diagram 9 on page 14. If the high limit continually shuts off the heater, refer to Section about Troubleshooting.

SECTION 8: 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 take care to 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

SECTION 9: WARNING PLACARDS

Two 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 placard must be attached to the door of the sauna room.

SECTION 10: 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.

• The warranty is void if a shower is 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 its 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.

• If a room light is installed, it should be a surface mounted bracket type. Wall mounted lights should be about 70" above the floor. Ceiling mounted lights should be of an approved type with a junction box that is remote to the fixture itself. Use only a fixture that uses A.F. or fixture type internal wiring. A 60 watt bulb should provide sufficient lighting.

• Fire sprinkler systems installed inside any sauna room should be properly rated for sauna room temperatures.

WARNING

The "CAUTION" and

"WARNING" placards

must be mounted in

accordance with Section 9.

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.

"Digi II" Series Heater Installation & Operation Instructions

SECTION 11: VENTILATION

VENTILATION 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 8.

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

SECTION 12: MAINTENANCE

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 deterioration should be replaced immediately to avoid possible injury.
