WARNING
Prolonged exposure to elevated temperatures is capable of inducing hyperthermia.
Hyperthermia occurs when the internal temperature of the body reaches several degrees above the normal body temperature of 98.6°F. The symptoms of hyperthermia include an increase in the normal temperature of the body, dizziness. lethargy, drowsiness, and fainting. The effects of the hyperthermia include failure to perceive heat, failure to recognize the need to exit the room, unawareness of impending hazard, fetal damage in pregnant women, physical inability to exit the room and unconsciousness.
WARNING
The use of alcohol, drugs, or medication is capable of greatly increasing the risk of fatal hyperthermia

SECTION 2: SECURING HEATER TO THE FLOOR page 3
WARNING
On the base of the heater are angle brackets and attached to the brackets are 2-1/2 screws for securing the heater to the sauna room floor.
The heater should be located in the sauna room observing the minimum spacing from wooden surfaces (walls or benches). The HEATER SPEC-
IFICATION CHART shows the minimum ceiling height and the minimum floorarea of the room in which the sauna heater may be used. Do not install benches over the top of heater
This heater must not be operated unless the rock compartment in the top of the heater is f illed with the igneous rocks that are furnished with the heater. They should be put on the heater so that the air is free to travel around them. Do not pack too tightly.
During the first operation, the rocks should be heated for two hours at maximum temperature with no one in the sauna room. This will allow any concealed moisture to be evaporated. If not, the moisture could cause the rocks to crack and possibly project fragments.
All wiring must be accomplished by a licensed electrical contractor. Referto the Heater Specification Chartto determine the wire size and circuit protection required. The complete sauna system consisting of heater, contactor assembly and temperature control should be properly ground- ed as per NEC or as required by local codes.
Grounding terminals are provided in the wiring compartments of each heater and also in the contactor assembly and temperature control.
Complete the wiring according to the appropriate
Diagram 1, 2, 3, 4 & 5.
The temperature control rough-in box should be installed flush in the wall, 5 feet up from the floor and so the opening is to the outside of the sauna room wall. The control is completely prewired and coded to simplify the field wiring. The capillary tube of the thermostat may go out through any knockout in the rough-in box. The preferred method isto run the tube within the wall as shown on diagram 3. The rubber grommet furnished with the control is to protect the capillary where it leaves the rough-in box. The capillary tubing bulb shall be covered with the protective shield furnished with the control. The screws for attaching the shield are included. Locate the tip of the capillary bulb at the ceiling near the heater.
Caution:
The tubing should be uncoiled carefully--the minimum bend radius of the tubing is 1/4 inch. Damage to the tubing will make the heater inoperative. The electrical wiring of the control should be as shown in Diagrams
1, 3, 4 & 5.
This heater is equipped with an overheat safety device. In the event of an abnormal heating condition. the heater will automatically shut off and the heater cannot be turned on again until the heater cools. The reset button is located on the top center of the junction box, under the painted shell. See Diagram 4. Pushing on the reset button, after the cooling period, will restore powerto the heater. If the reset button continues to trip , the factory service person should be notified.
Note:
Packing the rocks too tightly may cause the heater limit switch to trip.
Do not locate benches over heater.
Minimum height of ceiling above heater 40".
Do not construct sauna room so as to restrict air flow through the bottom of the heater.
Minimum clearance from heater to wooden surfaces (benches, side walls, heater fence etc.) 4 inches.
Mounting brackets supplied.
Provides proper clearance from wall behind heater.
Rock preheat required. Although the rocks are specially selected for use with this sauna heater, concealed moisture could cause the rock to crack and project fragments causing potential injury hazard when the rocks are heated.
The rocks must be preheated on the sauna heater for two hours at maximum temperature with no one in the sauna room.
Packing the rocks too tightly may cause the heater limit switch to trip.
Use only copper wire of the size and type indicated in the wiring diagrams and the temperature rating indicated on the heater junction box.
All heaters, controls and contactors must be grounded per NEC to prevent electrical shock in case of unit failure.
For fire and health safety, temperature controls C104A and
C105A may be used only where an attendant is present.
The tubing should be uncoiled carefully -- the minimum bend radius of the tubing is 1/4". Damage to the tubing will make the heater inoperative.

WARNING
Electrical outlets or receptacles must not be installed in a sauna room.
It is required that a guard rail or fence be constructed around the sauna heater to prevent the bather from making physical contact with the heating unit. The guard rail must not be closer than four inches to the exterior walls of the heater. If the heater is to be located in the corner of the room, one section of the guard rail may be deleted. See diagram 6.
Two metal placards are included in the Installation Instruction envelope packaged with every
Amerec 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 clear acrylic placard printed "SAUNA BATHER IN-
STRUCTIONS" should be mounted outside the sauna room, next to the door, at eye level. Nails for attaching the placard are furnished.
SECTION 10: THERMOMETER/HUMIDITY GAUGE
(Not furnished with heater. Available from your wall so that gauge can be observed from outside

SECTION 13: OPERATING INSTRUCTIONS (Cont.)
Caution:
When turning on your sauna for the first time follow steps 1 and 2 and let the heater run with no one in the sauna room through two cycles a full 120 minutes. This will allow excess oil to burn off the heating elements without causing any discomforttothe bather.
Step 1: Set the temperature rotating knob on
10. This is the highest heat setting. and the red indicating light goes out. At this setting the heat will cycle ON and OFF and maintain approximatelythetemperature nowappearing on the wall thermometer.
After you have used the Sauna a few times, you should be able to determine the number on the rotating dial that will give you the temperature that you prefer for your Sauna bath.
Step 2: If your temperature control is C102A or
C103A turn the one hour timer to its maximum setting (60 minutes).
Step 4: After you have finished your Sauna bath turn the switches OFF. The timer switch may be advanced at any time during your Sauna, or it will automatically shut the heater off when time has expired.
Step 3: Observe the wall thermometer (heat indicator) in the Sauna room (6"from the ceiling) and when it shows a temperature that feels satisfactory to you (160° to 180° F is normal) slowly rotate the temperature knob from 10 back towards the OFF position until you hear a click
Note:
Your temperature control has a red indicating light; you will observe that this glows only when power is actually going to the heating elements.
The Sauna, like a bathroom, should be kept clean and odor free. 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. 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
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.
