SAFETY PRECAUTIONS
● Read the following "SAFETY PRECAUTIONS" carefully before installation.
● Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, care and maintenance as stated in
instructions. Please remind the customer to keep the operating instructions for future reference.
WARNING
This indication shows the possibility of causing death or serious injury.
CAUTION
This indication shows the possibility of causing harm or damage the equipment.
1) Use qualified installer and follow carefully this instructions. Otherwise it will cause electrical shock, water leakage, or esthetic problem.
2) Install at a strong and firm location which is able to withstand the set's weight. If the strength is not enough or installation is not properly done, the set
will drop and cause injury.
3) For electrical work, follow the local national wiring standard, regulation and this installation instruction. An independent circuit and single outlet must
be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
4) Use the specified cable and connect tightly for indoor connection. Connect tightly and clamp the cable so that no external force will be acted on the
terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
5) Wire routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat-up
at connection point of terminal, fire or electrical shock.
6) When carrying out piping connection, take care not to let air substances other than the specified refrigerant go into refrigeration cycle. Otherwise, it
will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
7) Do not damage or use unspecified power supply cord. Otherwise, it will cause fire or electrical shock.
8) This equipment must be earthed. It may cause electrical shock if the grounding is not perfect.
9) Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may
cause fire.
10) Please diconnect the power supply when install or maintenance or sevice this system.
1) Selection of the installation location.
Select a installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance.
2) Do not release refrigerant.
Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take care of the liquid refrigerant.
it may cause frostbite.
3) It may need two people to carry out the installation work.
4) Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.
5) Carry out drainage pipes as mentioned in installation instructions. If drainage is not perfect, water may enter the room and damage the furniture.

- Page 3 Horizontal drainage ● The unit includes a drain pump, which can elevate condensate water up to 120 cm from the unit lowest level. The drainage tube is connected to the upper drainage nozzle. ● The lower drainage nozzle role is to empty the drain pan before servicing the unit. ● Install on the drain tube with 5-10 mm thickness thermal insulation sleeve to prevent drippings. Drainage test For VRF system please do drainage test after finishing all installations, wiring and piping included, and doing ITEST (Installation test ) sucessfully: (1) Power on the system, and runs cooling mode. (2) Check whether the pump sound is normal. (3) Slowly inject about 1,000 cc of water into the drain pan.Check the drainage through the transparent drain port to see if any drain leakage happens. (4) When the check is finished, do not forget to cut off the power supply. 3.UNIT DIMENSIONS Unit:mm Model DLV007-DLV015 DLV018-DLV024 1050 1090 4.ACCESS TO THE UNIT 5.UNIT INSTALLATION Insert 4 M10 or 3/8 threads rods into the ceiling.

Remove panel4. Remove filter trails 2-3. Insert filter trails 2-3 on the opposite side of the unit. 5.Close panel 4 in the rear side of the unit. Insert the filter into the trails. DISPLAY CONTROL UNIT 1.LOCATION CRITERIA ● It is recommended to install the Display Control Unit close to a ceiling in a central and neutral zone at typical conditions. In addition, the aesthetic aspect should be considered. ● The Display Control Unit is connected to the main control board on the air conditioner (the indoor unit) by a communication cable. Cable is connected to the Display Control Unit by a quick-connector. (8 pin plug) 2.INSTALLATION OF DISPLAY CONTROL UNIT ON WALL ● Drill a 12 mm diameter hole on the wall, for routing the communication cable. ● Open the unit cover, drill 3 holes in the wall to match the holes in the Display Control Unit, install the inserts and fasten the unit to the wall with 3 screws. ● The Display Control Unit is provided of a special communication cable, 7 meters long, terminated by a plug, connected in the housing itself to a distribution box, which enables the control of the air conditioner from several different rooms, each one from its own Display Control Unit. ● Connect the quick connector to the appropriate socket on the main control board in the indoor unit electrical box. 3.CONSIDERATIONS IN LOCATING THE REMOTE CONTROL UNIT a) Locate the Remote Control Unit in such a way that when mounted on its support on the wall, it will be in line sight with the Display Control Unit (at less than 8 m). b) It is recommended to establish the final location of the Remote Control Unit only after the first operation, assuring proper transmission and reception between the Remote Control Unit and the Display Control Unit.
