Operation

Figure 1: Primary Side Controls

WARNING: This unit must be properly installed before it is used. Air intakes located below the unit are essential. See “Installation” section of the Owner’s Manual for further information.

There are three different control options available for the unit: manual (under the media plate), tethered controller (must be connected to the unit) and a remote control.

The CDFI1000P and the CDFI1000-PRO units have two separate internal modules that are controlled by the settings entered on the left side (primary). The primary side controls include the power switch and standby button, whereas the secondary side controls do not. Finer adjustment can be done using the controls on the right module to have both modules operating at the same level (secondary).

NOTE: When the unit 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 flame effect. This is normal and should not be a cause for concern.
NOTE: Always ensure that the appliance is fixed to the framing in a level position.

Controls

A. On/Off Switch

Supplies power to the unit.
When the switch is set to the On position, the unit will emit one beep. The unit will be in standby mode when it is first powered on. The unit can be operated using any of the control options (onboard, tethered controller, or remote control).

NOTE: When the unit is first turned on the lights will come on and mist will appear 45 seconds later.

B. Standby

Turns the operation of the flame effect on or off.

C. Bluetooth
Required for synchronization of the remote, see synchronization instructions for more detail.

D. Test Mode
Used for troubleshooting issues – outlined in the Test Mode section of this service manual

E. Flame Intensity Control
Adjusts the intensity of the flame and smoke effect when the unit has been activated.
Pressing the will decrease the flame effect and pressing the will increase the flame effect. One beep will be heard when the flame height has reached the minimum or maximum level.

NOTE: A few moments will be required between adjustment and a change to the flame effect.

NOTE: During normal operation it is expected to see some condensation of water on the media plate. This will vary depending on ambient conditions and should be considered normal.

NOTE: When the water tank is empty, the flame effect shuts OFF and the LED’s will blink.

F. Volume Control
Adjusts the volume of the wood fire sound effects.
On the unit : Pressing the will decrease the volume and pressing the will increase the volume.
On the Remote and Tethered Controller: Pressing the will turn the volume On and Off.

Remote Control

Remote Control and Tethered Controller for CDFI1000P

Remote Control and Tethered Controller for CDFI500-PRO and CDFI1000-PRO

The tethered controller serves as the bluetooth receiver for communication with the remote, and must be connected for remote operation of the unit. It can also be used in the same manner as the remote.
The tethered controller must be connected to the unit and On/ Off Switch must be in the ‘ON’ ( I ) position in order for the remote to operate.

NOTE: To operate correctly the remote control must be synchronized with the unit.

Remote Control Synchronization / Pairing

In order for the remote control to communicate with the unit the bluetooth must be setup, as outlined below:

Verify that the tethered controller is connected correctly and that the plug is inserted all the way.
Place the On/Off Switch (Figure 1A) in the ON (“I”) position. The red light on the tethered controller will be illuminated.
Press the Standby button to activate the flame effect.
Press the Bluetooth synchronization button on the Primary controls (left side).
The unit will begin to beep and turn the lights ON and OFF every 2 ½ seconds to indicate that the unit is in synchronization mode.
Within 20 seconds of pressing the blue tooth button, press any button on the remote control (Figure 1).
NOTE: You will have only 20 seconds to perform this last step. Failure to do so will result in these steps needing to be followed again.
If the synchronization was successful the LED’s will blink 5 times and beep 5 times then the unit will go to Standby

This will synchronize the remote control and the tethered controller.

NOTE: It is possible to synchronize up to 5 units to one remote control.

Battery Replacement

Figure 3

To replace the battery:

Slide battery cover open on the remote control (Figure 3).
Install two 1.5 Volt (AAA) battery in the battery holder.
Close the battery cover.
Battery must be recycled or disposed of properly. Check with your Local Authority or Retailer for recycling advice in your area

Maintenance

WARNING: Disconnect power before attempting any maintenance or cleaning to reduce the risk of fire, electric shock or damage to persons.

Filling the water tank (Refillable bottle)

When the water tank is low, the flame effect will shut off and the unit will emit an audible beep and continuously blink twice every ten seconds. To refill the bottle(s), follow these steps.

Gently remove the top tray and place it carefully on the ground.
Turn the On/Off switch to the off position (0) (Figure 1A)
Remove the refill container by lifting upwards and outwards.
Refill the container with tap water.
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 ⅛ tsp. of salt (0.5 mL) added to the water reservoir. (The use of additional salt should only be when you notice that the unit is not producing mist as expected.)
Screw the cap back on, do not overtighten.
Return the refill container to the sump, with the tank cap facing down and the flat side of the tank facing outward.
Turn the On/Off switch to the off position (I). (Figure 1A)
Gently place the top tray back into position.

If you do not intend on using the unit for longer than 2 weeks, empty and drain the unit of water, and dry all of the water containing components.

Transducer Replacement

After prolonged usage the ability for the unit to produce mist may become reduced. When this occurs the replacement of the transducer may be required. This unit comes with 2 additional transducers, located behind the right module, which can installed when this occurs.

NOTE: There is a small tab that holds the transducer in place, that needs to be released before it can be removed.

Cleaning
It is recommended that the top cover assembly, sump and transducer are cleaned with soap and water on a biweekly basis.

CAUTION: Do not put plastic components in the dishwasher.

Filter Cleaning
The air filters can be removed and gently rinsed with water to clean and dried on a towel before reinstalling.

NOTE: Replace the filter so that the course black filter is facing the back of the unit.

Surface Cleaning

Use a warm damp cloth only to clean surfaces of the unit. Do not use abrasive cleaners.

NOTE: If you need to move the unit ensure that all of the components that contain water have been emptied before relocating.

Servicing

Except for installation and cleaning described in this manual, an authorized service representative should perform any other servicing.
