Installation
WARNING: Ensure the power
cord is not installed so that it is
pinched or against a sharp edge
and ensure that the power cord is
stored or secured to avoid tripping
or snagging to reduce the risk
of re, electric shock or injury to
persons.
Grounding Instructions
This product must be grounded.
If it should malfunction or break-
down, grounding provides a path
of least resistance for electric
current to reduce the risk of
electric shock. This product is
equipped with a cord having an
equipment-grounding conductor
and a grounding plug. The plug
must be plugged into an appropri-
ate outlet that is properly installed
and grounded in accordance with
all local codes and ordinances.
DANGER: Improper connec-
tion of the equipment-grounding
conductor can result in a risk
of electric shock. Check with a
qualied electrician or serviceman
if you are in doubt as to whether
the product is properly grounded.
Do not modify the plug provided
with the product – if it will not t
the outlet, have a proper outlet
installed by a qualied electrician.
This product is for use on a
nominal 120-volt circuit and has
a grounding plug that looks like
the plug in Figure 1. Make sure
that the product is connected to
an outlet having the same con-
guration as the plug. No adapter
should be used with this product.
CAUTION: Risk of Electric
Shock. Unplug the cord before
moving or servicing this furnishing.
!NOTE: A 15 Amp, 120 Volt cir-
cuit is required. A dedicated circuit
is preferred but not essential in
all cases. A dedicated circuit will
be required if, after installation,
the circuit breaker trips or fuse
blows on a regular basis when the
cassette is operating. Additional
appliances on the same circuit
may exceed the current rating of
the circuit breaker.
Mantel Installation
Install the replace into the
mantel (refer to mantel assembly
instructions).

mum internal/opening dimen-
sions (Figure 2).
!NOTE: An air inlet is required
for optimum mist production, see
Figure 2 for minimum dimen-
sions.
!NOTE: For optimal perfor-
mance, 12 in. (305 mm) mini-
mum clearance between the in-
stallation surface and any surface
above should be maintained.

Assembly
Figure 4
1. Carefully unpack all of the
components from the box.
(Figure 4)
2. Remove top cover by turning
the retaining tabs on both
ends of the water reservoir.
(Figure 5)
3. Install the light bulbs by
aligning the pins on the bulbs
and the xture and pressing
down until they are fully
inserted. (Figure 6)
4. Install the transducer so that
it is sitting level in the circular
holding area in the reservoir.
5. Orient transducer wire so that
it does not sit directly above
the emitter and the wire
passes through the slot in the
side of the tank. (Figure 5)
6. Reinstall the top cover and
ensure both retaining tabs
have been turned so that they
are pointing inwards.
7. Fill and install the Rell
Container.
!NOTE: Normal tap water can
be used in the Optimyst® as long
as the tap water is not considered
to be hard water. In the event
your tap water is hard, you may
use softened water or distilled
water with 1/8 tsp of salt (0.5
mL) added to the water reservoir.
(The addition of additional salt
should only be used when you
notice that the unit is not produc-
ing mist as expected.)

Operation
!NOTE: Always ensure that the
appliance is in an upright position
before operating the unit.
!NOTE: When the cassette
is used in an environment where
background noise is very low, it
may be possible to hear a sound
which is related to the operation
of the ame effect. This is normal
and should not be a cause for
concern.
!NOTE: Always ensure that
the appliance is in a level position.
The manual controls for the cas-
sette are located on the top of
the unit, below the control cover.
(Figure 7)
A. On/Off Switch
Supplies power to the cassette.
B. Mode Selector Switch
Press once to turn on the ame
effect. This will be indicated by an
audible “beep”. Although the lights
turn on immediately it will take 30
seconds before the ame effect
starts.
Press to put re in to standby
mode. This will be indicated by
one “beep”.
C. Flame Intensity Control
Adjusts the intensity of the ame
effect when the cassette has
been activated.
Turning the control knob clock-
wise to decrease the intensity
of the ame effect. Turning the
control knob counter-clockwise
will increase the ame effect.
!NOTE: Give the ame genera-
tor some time to react to changes
you may make on the ame
control knob.
!NOTE: When the water tank is
empty the unit will turn off after 30
seconds. See instructions under
Maintenance Section for rell-
ing tank. When this procedure is
complete, the main lamps will illu-
minate but it will take 30 seconds
before the ames return.
