• The outlet and electrical circuit are adequate for the appliance.
• The outlet is a 3-hole grounded outlet . If this is not the case, you must choose another outlet. Failure to follow these important safety instructions absolves the manufacturer of all liability. If it becomes necessary, the power cable must be replaced by a qualified professional only.

USE
The instructions below will enable you to prepare your air conditioner for operation as efficiently as possible. Before use, make sure the air intake and air outlet flap are unobstructed.
Please   note: This appliance is provided with an auto-evaporation feature for condensate removal during cooling and dehumidifying modes.

AIR CONDITIONING INSTALLATION

For optimal results see the figures below for the suggested minimum distances.

DOUBLE-HUNG WINDOW

• Place the window bracket (B5) in the window sill, extend the bracket fully within the window frame (fig. 1).
• Fix the bracket into place by tightening the wing nut (fig. 2). Attach the provided stripping foam (B10) to the top of the window bracket and then lower the window onto the bracket. (Should the window bracket be too large for the window the plastic can be cut with a saw by a qualified professional.
• If the windows are large, use additional window bracket (B4) to cover your window opening, extending it to the required length, then securing it with the locking wing nut supplied (fig. 3).
• Insert and lock the accessory for window bracket (B1) already attached to the air exhaust hose, into the slot of the window bracket (fig. 4).
• At the other end, be sure hose adapter’s tab is straight up (like the 12 position on a clock) as shown in fig. 5.
• Attach assembled hose to the back of the air conditioner (fig. 6).

SLIDING WINDOWS

• Thanks to the locking wing nut, it’s possible to use the win – dow bracket also for sliding windows. Position the hole of the window bracket in the lower corner to allow for correct installation of the exhaust hose.

TIPS FOR CORRECT USE
To ensure optimal results from your air conditioner, follow these recommendations: Close the windows and doors where air conditioner will be used. When installing the air conditioner semi-perma-nently, you should leave a door slightly open (as little as 1/2 inch -1 cm) to guarantee proper ventilation. Never use the appliance in very damp rooms (laundries for example). Protect the room from direct exposure to the sun by par-tially closing curtains and/or blinds to make the appliance much more economical to run.

• Never use the appliance outdoors.
• Make sure there are no heat sources in the room.
• Make sure the air conditioner is standing on a level surface.
• Never rest objects of any kind on the air conditioner.
• Never obstruct the air intake or air outlet flap (see figure below).

CLEANING
Before cleaning or maintenance, turn the appliance off by using the button, then unplug from the outlet.
CLEANING THE CABINET
You should clean the appliance with a slightly damp cloth then dry with a dry cloth. For safety reasons, never wash the air conditioner with water. Attention! Never use petrol, alcohol or solvents to clean the appliance. Never spray insecticide liquids i or similar.
CLEANING THE AIR FILTER
If the filter is dirty, air circulation is compromised and the efficiency of the appliance decreases. It is therefore good practice to clean the filter at regular intervals. The frequency depends on the duration and conditions of operation. If the unit is used constantly or systematically, you are recommended to clean the 5 filter once a week. The filter is housed in the intake grille. To clean the filter, remove as shown in fig. 8.

Use a vacuum cleaner to remove the dust collected on the filter.
If it is very dirty, immerse in warm water and rinse a number of times. The water should never be hotter than 104°F. After washing the filter, allow it to dry completely before repositioning it.
The filter helps capture dust and pollen.
START OF SEASON CHECKS
Make sure the power cable and plug are undamaged and the ground system is sufficient.
Follow the installation instructions precisely.
END OF SEASON OPERATIONS
To drain all water from the circuit, remove the external cap by unscrewing it in the counter clockwise direction and allow the water to drain out into a basin (fig. 9).

When the appliance is empty, replace the caps.
Clean the filter and dry thoroughly before putting back.
In order to properly storage the appliance at the end of the season, we suggest you cover it with the supplied end of season dust cover (B9) and you put the accessories in the relevant max 33ft~ end of season accessories bag (B8).

TECHNICAL SPECIFICATIONS

ONLY FOR SERVICE CENTERS USE
THE WIRING DIAGRAM IS LOCATED INSIDE THE UNIT.

LIMIT CONDITIONS

Room temperature for air conditioning 61° ÷ 95°F (16-35 °C)
Maximum relative humidity 80% RH
Please note: outside of these conditions, the unit will take longer or may not reach the cooling temperature that is set.
Transport, filling, cleaning, recovery and disposal of refrigerant should be performed by a technical service centre appointed by the manufacturer only.
The appliance should be disposed of by a specialist centre appointed by the manufacturer only.
Attention! TO AVOID DAMAGE TO THE UNIT:
NEVER TRANSPORT OR TURN THE APPLIANCE UPSIDE DOWN OR ON ITS SIDE. IF THIS OCCURS, WAIT 6 HOURS BEFORE TURNING THE APPLIANCE ON, 24 HOURS IS RECOMMENDED. After the unit has been on its side, oil needs to return to the compressor to ensure proper function. Without allowing the unit this time (6-24 hours) the unit may function for only a short time, and then the compressor will break down from lack of oil.
