3.8. Troubleshooting
A. If sauna does not operate after initial installation
and wiring:
1. Check breaker to be sure that it is on. Also,
breaker should be correct size.
2. Make sure that a neutral wire has been included
3. Check circuit breaker in contactor to be sure that
it has not been shorted out.
4. Be sure that thermostat and timer are both in on
position.
5. Be sure that timer winds down. If timer has been
shorted out, heater will not operate.
B. If sauna has been in operation, but heater ceases
to operate:
1. Check breaker to make sure it is on.
2. Check timer to see if it winds down.
3. Check high limit reset button in heater (reset is
under the heater to see if it has been released).
4. Call your electrician or service person for further
help.
C. If Sauna heater operates, but room does not come
up to Sauna temperature (160–185°F (70–85°C)
normal Sauna temperature):
1. You must allow at least 30 minutes for Sauna heat-
up time.
2. Is Sauna thermometer located 6” (150 mm) from
ceiling, and is it above or close to Sauna heater?
(This is proper location for Sauna temperature
reading.) Thermometer readings vary with room
heights and location. Eg. 180°F (82°C) above
Sauna heater = 165°F (74°C) on opposite wall =
140°F (60°C) on upper bench level = 120°F
(49°C) on lower bench level = 100°F (38°C)at
floor level.
3. Check for proper wire size, amp size and proper
wiring (according to diagrams and information)
also necessary copper wiring.
4. Check for placement of stones to make sure they
are loosely spaced around elements, to insure
good air flow. Stones packed too tightly will
restrict air flow and reduce heating capacity.
5. Check for heat loss (around or under door, around
ceiling light or fan – we do not recommend ceiling
light and a fan does not belong in the Sauna.
6. Is room properly insulated?
7. Is ceiling higher than in figure 4?
8. After checking all of the above, remove rocks and
check heater elements for holes or burned areas.
(Only if heater has been in use for some time.)
3.9. Caution! Electrician or service person!
1. Before servicing heater, control, or contactor, turn
power off at breaker!
2. Open junction box to make sure wires are tightly
secured with no loose connections. Heater wire
and all connecting wires should be copper.
3. Check for burned spots or short in wiring of timer
or thermostat.
3.10. Maintenance instructions
1. Use only clean water on Sauna stones. Do not use
spa or pool water as it will destroy your heater.
2. Clean water should always be used in Sauna
buckets and water should be dumped out after
every use. Scour buckets and dippers occasionally
when film collects from usage. Use plastic bucket
liner in bucket to prevent water leakage.
3. Scrub benches with a soft brush, using soap and
water or a mild disinfectant, when needed - about
once a week in commercial Saunas, or depending
upon sauna usage. For sanitation, each bather
should sit or lie on a towel (this will prolong bench
life).
4. Remove Super Dek and wash waterproof floor
with disinfectant (e.g. Pine Sol) about once a week
or as often as needed. Hose off Super Dek to clean.
5. To maintain beautiful appearance of Sauna heater,
remove water stains by wiping a damp cloth
occasionally.
6. Harvia Sauna Heaters require no special
maintenance when properly installed by a qualified
electrical contractor. After 1 years of usage, the
rocks may need replacing if they have crumbled or
powered.
7. Harvia Sauna strongly recommends a floor that
can be easily cleaned (concrete, ceramic tile, or
a poured type of flooring). When this is provided,
the Sauna can be easily cleaned and kept in a
sanitary condition with little effort. A carpet is
NOT recommended for a Sauna! A carpet
becomes a perfect breeding ground for bacteria
in the moist conditions of a Sauna; and a carpet
promotes the spread of foot diseases such as
athlete‘s foot. For same reasons, wooden
duckboard should not be used for flooring.
8. In new construction, a floor drain should also be
provided, especially in commersial Saunas for
sanitary cleaning and maintenance.
9. Seal wood around glass in door - inside and outside
with Thompson‘s Water Seal to prevent
warpage.
10. When Sauna wood becomes stained from
perspiration, the wood may lightly sanded with fine
sandpaper to restore beautiful appearance. We do
not recommend stains or sealers as toxic vapors
may appear when heated. However, 2 coats of
Thompson‘s Water Seal may be used on the wood
benches in a commersial Sauna, so that the wood
may be more easily cleaned and kept sanitary – the
wood will not absorb perspiration.
11. The Sauna room will heat faster if the higher vent
is kept in a closed position when heating. The lower
vent may always be kept in an open position.
12. Required warning signs should be posted
according to the instructions.
