SECTION 4: 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. 1½ 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 damage may result.

SECTION 5: 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.

SECTION 6: 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 CN7 location on the main board. If it is open, close the two pins.
