Haier 5U125S2PN1FA Installation Manual page 5

Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage.
If the gas leaks and builds up around the unit, it may catch fire or explosion.
Establish drain piping according to the instructions of this manual.
Inadequate piping may cause flooding.
Tighten the flare nut according to the specified method such as with a torque wrench.
If the flare nut is tightened too hard, the falre nut may crack after a long time and cause refrigerant leakage.
Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke fire, or explosion. Please instruct the customer to
keep the area around the unit clean.
