1.Air condition needs to be equipped with drain pipe.
Connect the drain pipe to the drain and place the other end of the drain pipe into a container or drain area.
2. The machine should be kept level when it is in use. It is best to leanitbackward5-10 degrees, not forward or left or
right, otherwise the condensate water will leakfrom the front, side andbottom of the air conditioner.
3. Do not move the air conditioner immediately after using the air conditioner. Tilt the air conditioner backwardsslowly
by 30 degrees to ensure that the water in the air conditioner is drained.
Note: if there is leakage due to improper placement, there is no need to be nervous, just wipe it or cool it naturally, it will
not affect the performance of the machine.

Cautions When Placing Exhaust Hoses
•To ensure proper functioning, do not extend or bend the hose excessively.
•Make sure there are no obstacles around the exhaust hose outlet (within 500mm) for the exhaust system to work
properly.
•All illustrations in this manual are for illustration only. Your air conditioner may be slightly different depending on the
actual product.
a.Use the protection panel (in the Mark 2 battery pack-
age) as the window baffle.
This is only included in Zero Breeze Plus and Zero
Breeze PE series.
b.DIY to cut out two circular holes with a diameter of
11cm, the distance of 15cm between each hole.
Use a utility knife to remove the excess. If the width is not enough, cut out some other foam and stitch it together.
Choose the right angle and place it on the window. Close the window and insert the two exhaust pipes into the round
holes.
This accessory can be used in some environments, such as the cab, where it is not convenient to place the Mark 2 for
cold air to reach the position we want. Remove the 2 rubber plugs on the front panel of Mark 2 and align the adapter
with Mark 2. Tighten the two screws, hold the adapter with one hand, and pull the air duct to the desired position.
•When adjusting the position of the cold air pipe, press the extension adapter with the other hand
