SECTION 7: DC60 CONTROL INSTALLATION & OPERATION
Do not locate benches over
heater. Minimum clearance
of ceiling above heater 44".
Minimum clearance from
heater to wooden surfaces
(benches, side walls, heater
fence etc.) 2 inches.
Mounting brackets supplied.
Provides proper clearance
from wall behind heater.
Use only copper wire of the
size and type indicated in the
Heater Specication Chart
and the temperature rating
indicated on the heater
junction box.
All heaters and controls must
be grounded per NEC to
prevent electrical shock in
case of unit failure.
Electrical outlets or
receptacle must not be
installed in a sauna room.
A guardrail or fence is
required around the heater to
prevent burns from
accidental contact.
The DC60 control uses low voltage to switch your sauna heater on and off,
to adjust the room temperature, and to adjust the length of your sauna
bath. Either one or two controls may be connected to the heater. When
power is connected to the heater, the room temperature setting is
automatically preset to 175°F and the bath time is set to 45 minutes.
These settings are adjustable (as described below) from 150° to 194° and
from 5 to 60 minutes and any changes are remembered by the heater for
your next bath. Should the heaters power be lost then restored, the
settings will return to their 175°/45 minute default values.
INSTALLATION ROUGH IN The low voltage control must be mounted
outside the sauna room. Drill a 2" hole in the wall at the desired switch
location. String 25 foot cable through 1/2" holes in the wall studs or ceiling
joists from the switch location to the heater. Note: Use the factory
supplied cable only! Do not staple through or otherwise damage the cable!
With the decorative cover removed from the DC60 switch assembly, insert
the two control mounting screws through the control housing (may need to
punch through skinned holes) and screw 1/4" into the mounting bracket.
Locate the control cable and plug it into the jack on the back of the control
housing. Insert the mounting bracket into the wall cavity by rst pushing
with the control housing then with a hard at surface on the face of the
control housing mounting screws which extend out through the control
face. Once the mounting bracket has been inserted into the nished wall,
center the control and tighten the mounting screws to draw the control
housing securely against the nished wall. Do not over tighten the
mounting screws. Install the decorative cover plate by sliding the top of
the cover plate over the tab on the top of the control housing and pushing
on the bottom of the cover plate to complete the snap t. Route the heater
end of the control cable through the small electrical access hole at the
bottom of the heater and connect it to either J1 or J2 on the heater circuit
board. If two controls are to be installed, plug the second cable into the
remaining connector. It does not matter which of the two connectors is
connected to a control. Do not attempt to plug in more than one control
to a single connector!
OPERATION With the power circuit to the heater turned on, press the
control ON/OFF button once. The room temperature will be displayed on
the control. The heater will turn on and begin heating the room. Once the
selected bath temperature is reached, the heater will turn off and on again
as needed to maintain the desired temperature. At the end of the selected
bath time, the heater will turn itself off and the control display will turn off
again.

WARNING
SECTION 10: WARNING PLACARDS
SECTION 11: ROOM CONSTRUCTION
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 xtures get very hot
during operation. Locate
light xture where it will not
be a burn hazard.
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.
The "CAUTION" and
"WARNING" placards must be
mounted in accordance with
Section 10.
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 ttings 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 re … caution plate must be
mounted on the interior wall above the heater.
• The heater should not be operated without its container properly lled
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 oor 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 oor. Ceiling
mounted lights should be of an approved type with a junction box that is
remote to the xture itself. Use only a xture that uses A.F. or xture

SECTION 11: VENTILATION
SECTION 12: MAINTENANCE
VENTILATION 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.
It is recommended that ventilation openings meet the requirements of UL Specication 875. The minimum opening
should be determined using one of the following formulas:
For R< 31, V ³9.3
For R ³31, V ³0.3R
where R = the oor area of the room in square feet and
V = the minimum vent size in square inches
The sauna, like a bathroom, should be kept clean and odor free.
Towels or mats should always be used on benches and oor 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 oor 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 13: TROUBLESHOOTING
Control will Not Power Up - Press (reset) the high limit switch on the bottom of heater.
Control Display E001 - Sensor is not connected or broken wire to sensor.
Control Display E002 - Sensor or wire is shorted together.
Slow Heat Time or High Limit Tripping - Check rock placement, they will break down over time and reduce the air
ow in the heater. Refer to Diagram 10 for proper rock installation. Discard all rocks under the size of 2" peices. Call
the number below to order more rocks if needed.
