The provided Remote Control allows the unit to be operated from a distance.
• Even if the Remote Control is operated within the effective range (6m), remote control operation
may be impossible if there are any obstacles between the unit and the remote control.
• If the Remote Control is operated near other products which generate infrared rays, or if other
remote control devices using infra-red rays are used near the unit, it may operate incorrectly.
Conversely, the other products may operate incorrectly.
First-time use:
The unit has a pre-installed lithium CR2032 battery.
Remove the protective tab to activate the remote control battery.
Replace the Remote Control Battery
- The remote control requires a CR2032, 3V Lithium battery.
1. Loosen the screw with a screwdriver (not
included) and slide the back cover to open
the battery compartment of the remote
control.
2. Replace with a new battery.
3. Close the battery compartment cover.
Tighten the screw with a screwdriver (not
included).
Precautions Concerning Batteries
1 When the Remote Control is not to be used for a long time (more than a month), remove the
battery from the Remote Control to prevent it from leaking.
2 If the batteries leak, wipe away the leakage inside the battery compartment and replace the
batteries with new ones.
3 Do not use any batteries other than those specified.
4 Do not heat or disassemble batteries.
Never throw them in fire or water.
5 Do not carry or store batteries with other metallic objects. Doing so could cause batteries to short
circuit, leak or explode.
6 Never recharge a battery unless it is confirmed to be a rechargeable type.

installer’s responsibility to verify that the wall will safely support the total load of the unit and wall
brackets.
- Additional tools (not included) are required for the installation.
- Do not overtighten screws.
- Keep this instruction manual for future reference.
- Use an electronic stud finder to check the wall type before drilling and mounting.
Remove the screws from the main unit. Attach the wall brackets to the main unit with
the screws removed from the main unit.
Drill 2 parallel holes (Ø 3-8 mm each according
to wall type) in the wall. The distance between
the holes should be 914 mm.
Leave a 5 mm gap between the wall and the screw’s head. Lift the unit with the attached wall
brackets over the heads of the screws and slot into place.
Firmly fix 1 dowel into each hole in the wall
if necessary.
