How does your Pinguino work

Optimum comfort is achieved at around 24°C and 50% relative humidity. The air conditioner removes moisture and heat from the room. Portable units can be moved between rooms or buildings.

Hot air from the room passes through a coil cooled by refrigerant gas, removing excess heat and moisture before being discharged back into the room. In single unit models, a small amount of air cools the refrigerant gas, and the hot, moist air is discharged outside.

Setting up

Air Conditioning without Installation (for Instant Temporary Usage)

1. Fix the exhaust hose 26 to the coupling 10 on the back of the unit (Figure A).
2. Fix the window attachment 27 to the end of the hose 26.
3. Place the unit near a window, French window, or door.
4. Open the window, French window, or door slightly and place the window attachment 27 as shown in Figure B.
5. For double casement windows, use the suckers 28 to hold the window halves together (Figure C).

For optimum results (Sash Window):

1. Place the bracket 31 on the window sill.
2. Extend the bracket fully within the window frame.
3. Fix the bracket by turning the wing nut and lower the window onto the bracket.
4. Insert the window attachment 27 of the exhaust hose 26 into the slot.
5. Connect the hose to the air conditioner (Figure C1).

The wing nut allows the window bracket to be used for sliding windows as well. Position the bracket's hole to allow correct installation of the exhaust hose.

Air Conditioning with Installation (for Semi-Permanent Installation)

1. Fit the flange 25 to the hole.
2. Fix the hose 26 to the coupling on the back of the unit (Figure A).
3. Attach the end of the hose 26 to the flange 25 (Figure E).

To install, make a hole in an outside wall or through a window glass. Check height and dimensions in Figure D.

When the hose 26 is not attached, close the hole with the bung on the flange 25.

NOTE: When installed semi-permanently, leave a door slightly open (approx. 1 cm) for adequate air exchange.

Preparation for Use

How to Use the Air Conditioner with Water

The air conditioners can use air and water to cool the condenser. Filling the tank 6 with water increases cooling power and reduces noise and energy consumption. Water is expelled as vapor through the exhaust hose 26.

• Always use clean top water.
• Water typically lasts about 8 hours, depending on room conditions. Turbo mode uses water more quickly.
• The unit can be used in air cooling only mode (without filling the water tank) for lower cooling power.

A) Opening the Front Panel:

Grip the front panel 3 on both sides and pull it towards you and upwards. Lift the tank 6 forward to remove it.

B) Filling the Tank:

Turn the tank upside down, remove the plug, remove the extendible tube, and fill the tank while it is on the ground.

C) Replacing the Tank:

After filling, replace the extendible tube, replace the cap, and screw it in tightly. Return the tank to its place with the 'FRONT' label clearly visible. Carefully hold the panel in the center and lower it to its closed position.

A slight gurgling sound during water operation is normal.

In High Humidity Conditions:

Water extracted from the air is used to cool the condenser. Excess water may build up in the internal tank and can be drained by removing the bung from the drain hose 11.

IMPORTANT: If room temperature is 32°C or over, the air conditioner must be operated with water in the tank.

Turning On and Setting the Timer

Electrical Connection

• Ensure the mains supply matches the rating plate.
• Check the socket and mains lead match the appliance's power requirements.
• Ensure the socket is suitable for the plug; replace if necessary.
• Ensure the socket is properly grounded.

The manufacturer is not liable for damages due to failure to follow safety procedures. Power cable replacement must be done by qualified personnel.

Setting the Timer (if supplied)

Set the programmer/timer 16 to the exact time. Turn the dial clockwise until the desired hour aligns with the pointer.

N.B.: Never turn the dial counter-clockwise.

The timer functions when the plug is connected to the power supply. If the plug is disconnected or there is a power failure, the timer must be reset.

Programmed Mode
