High above in the sky is moved implement when cannot moving --
1. Whether does examination power source have report, whether is the limits of voltage 220V ± 10% in (usable avometer or electrography test) .
Whether does the batteries inside 2. inspection remote controller have report (considerable examine liquid crystal shows clear) .
3. set parameter is correct. If run temperature of condition, set,wait.
Have near the machine inside 4. examination disturb without electromagnetism, wait like fluorescent lamp, may disturb the signal that the remote controller transmits.
High above in the sky is moved implement when refrigerating capacity is insufficient --
Whether does 1. inspection door window close close, indoor whether to have add heat source newly, wait like personnel, electric equipment.
2. screen pack is clean, air inlet of room inside and outside, give wind gap whether unobstructed, wind of pass in and out forms short loop.
3. set parameter is correct, if whether wind speed is in high gear.
Situation of heat exchange of the 4. machine outdoor is favorable, have without get sunshine point-blank, the effect that plays a wind without the machine outside getting other air conditioning waits.

High above in the sky is moved implement drop water, slack when --
1. checks drainpipe whether screwy, squash, whether burst.
2. drainpipe is exported whether dip is in water, correct should be to show water.
3. room inside and outside joins the canal wraps up complete, have without appear part. Like disclosure indoor copper pipe has a knot to show a phenomenon, the stuff with usable good heat proof quality wraps up.

High above in the sky is moved implement when noise is bigger --
1. affirms whether sound comes from air conditioning.
2. air conditioning is started or stop when machine, inside machine is plastic a sound that because of temperature metabolic happening bilges to shrink and be given out belong to normal phenomenon.
Machine of 3. inside and outside secures wall to whether bear fruit.
4. checks room inside and outside to join whether the canal has been secured, have not have and the machine outdoor or other object produce collision.
5. air conditioning is started or stop when machine, cold intermediary is in inside the system noisier flow sound can be given out before achieving a balance, belong to normal phenomenon.

Hot pump air conditioning (changes in temperature air conditioning) welcome as a result of its economy by broad user, use in the center may encounter the following kinds of situations:
After when 1. makes heat, switching on the mobile phone, outside machine start, inside machine do not move. This is normal prevent air cooling to blow a protection, when inside after machine accumulation of heat is finished, can begin to move.
When 2. air is colder, after empty modulation heats up, can appear indoor machine stays turn a few minutes, this is normal change frost to move, surface of the heat exchanger in moving because of the machine outdoor is met frost, affected further heat exchange result thereby, must undertake defrost so.
