SECTION 1: GENERAL INFORMATION
These heaters are ETL approved by Intertek for permanent installations.
All wiring must be performed in accordance with the NEC and local
codes. See Table 1 for wire and room size requirements.
These heaters are free standing, secured to the floor, with separate
controls.
Pro 10.5, 12.0, & 14.4 (Model # 1105-105, 1105-120 & 1105-140)
Laava 10.5, 12.0, & 14.4 (Model # 1105-1052, 1105-1202 & 1105-1402)
Octa 10.5, 12.0, & 14.4 (Model #1106-105, 1106-120, & 1106-140)

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.
CB 9-1 or
CB 9-3
Do not take a sauna if using
alcohol, drugs or
medications.
Pregnant women or persons
with poor health should
consult their physician before
using any sauna.
Caution fire hazard: Do not
use the sauna room for
drying clothes, bathing suits,
etc. Do not hang towels
above heater or place any
object other than the rocks
supplied on the heater. If any
darkening of the wall around
the heater is noticed
discontinue sauna use
immediately.
Inspect sauna regularly for
required maintenance to
heater, control and benches.
Replace wood surfaces which
show any signs of
deterioration.
The heater gets extremely hot
during operation and should
not be touched or burns may
result.
Minors should be adequately
supervised whenever near a
hot or warming sauna.

WARNING
SECTION 2: MOUNTING OF SAUNA HEATER
SECTION 3: PLACING OF ROCKS
Carefully locate the heater according to the dimensions shown in
Diagram 1 and bolt it to the floor. (Bolts are not supplied with the
heater.) Tighten to secure the heater in place.
The rocks supplied with the heater have been chosen to provide the best
heater performance. Use of any other type of rock may void the heaters
warranty. Never operate the heater without rocks in place! Rinse the
rocks with water before placing in the heater. Place the larger rocks at
the bottom and the smallest at the top. Place the rocks loosely so that
the air can circulate through the heater. Packing the rocks too tightly
may cause the heater high limit switch to trip. The rocks must fully
cover the heating elements. Attach the guard with the screws provided.
SECTION 4: ELECTRICAL HOOK-UP
SECTION 6: HEATER SCREEN (GUARD RAIL)
Electrical installation must be made by a licensed electrician in
accordance with the National Electrical Code and local regulations.
This heater is intended for use with Digi I, Digi II, or Digi VII controls
only. Use of any other control will void the warranty and UL listing.
The control must be installed in a dry location outside the sauna room.
The location must be selected to allow installation of the thermostat's
temperature sensor shown in Diagram 1. (9 foot sensor wire supplied,
but may be extended with equivalent 2 conductor wire.)
The model CB 9-3 contactor is required for use with 3 phase heaters,
the model CB 9-1 contactor is required for use with single phase
heaters. To determine the correct wire size, refer to Table 1. Use
copper supply wire only, suitable for minimum 90 degrees C. The
heater must be grounded! See the heater diagrams for proper
connections.
Install a wooden heater guard to prevent the sauna bather from
accidentally touching the sauna heater. Install the heater guard rail with
the height clearances and dimensions shown in Diagram 1.
SECTION 5: TEMPERATURE SENSOR
Route the sensor wire from the contactor box to the sensor location. It
may be necessary to drill holes to string the wire through the studs or
ceiling joists. Route wires into contactor box and connect to terminals
#1 and #2 of J3. Ensure low voltage wiring and high voltage wiring is
separated by a minimum of 4"or an electrical barrier. With a flat tip
screwdriver, unsnap sensor cover from sensor. Mount sensor
horizontally to the finished wall directly above heater 2" inches down
from ceiling. Refer to Diagrams 1, 2, & 3 for installation information.
Fire sprinkler systems used
inside any sauna room
should be properly rated for
sauna room temperatures.
Do not pour chlorinated pool
or spa water on heater.
Excessive water use on
heater may cause damage
and void warranty.
Do not install a shower in
sauna room.
Electric Shock Hazard - High
voltage exists within this
equipment. There are no
user serviceable parts in this
equipment. All installation
and service to this equipment
should be performed by
qualified licensed personnel
in accordance with local and
national codes.
Do not construct sauna room
so as to restrict air flow
through the bottom of the
heater.
Packing the rocks too tightly
may cause the heater high
limit switch to trip.
