Haier CWH24A ユーザーズマニュアル

■

Too many appliances are being used on the same circuit. 
Unplug or relocate appliances that share the same circuit.

■

Time-delay fuse or circuit breaker of the wrong capacity 
is being used. Replace with a time-delay fuse or circuit 
breaker of the correct capacity. See “Electrical 
Requirements.”

■

An extension cord is being used. Do not use an extension 
cord with this or any other appliance.

■

You are trying to restart the air conditioner too soon after 
turning off the air conditioner. Wait at least 3 minutes after 
turning off the air conditioner before trying to restart the air 
conditioner.

■

Disturbances in your electrical current can trip (Reset 
button will pop out) the power supply cord. Press and 
release RESET (listen for click; Reset button will latch and on 
some devices, a green light will turn on) to resume operation.

■

Electrical overloading, overheating, cord pinching or 
aging can trip (Reset button will pop out) the power 
supply cord. After correcting the problem, press and release 
RESET (listen for click; Reset button will latch and on some 
devices, a green light will turn on) to resume operation.

NOTE: A damaged power supply cord must be replaced with a 
new power supply cord obtained from the product manufacturer 
and must not be repaired.

■

The current air conditioner replaced an older model. The 
use of more efficient components may cause the air 
conditioner to run longer than an older model, but the total 
energy consumption will be less. Newer air conditioners do 
not emit the “blast” of cold air you may be accustomed to 
from older air conditioners, but this is not an indication of 
lesser cooling capacity or efficiency. Refer to the efficiency 
rating (EER) and capacity rating (in Btu/h) marked on the air 
conditioner.

■

The air conditioner is in a heavily occupied room, or heat-
producing appliances are in use in the room. Use exhaust 
vent fans while cooking or bathing and try not to use heat-
producing appliances during the hottest part of the day. A 
higher capacity air conditioner may be required, depending 
on the size of the room being cooled.

■

The air conditioner is not properly sized for your room. 
Check the cooling capabilities of your room air conditioner. 
Room air conditioners are not designed to cool multiple 
rooms. 

■

The filter is dirty or obstructed by debris. Clean the filter. 

■

The inside evaporator and outside condenser coils are 
dirty or obstructed by debris. See “Annual Maintenance.”

■

There is excessive heat or moisture (open container 
cooking, showers, etc.) in the room. Use a fan to exhaust 
heat or moisture from the room. Try not to use heat-
producing appliances during the hottest part of the day.

■

The louvers are blocked. Install the air conditioner in a 
location where the louvers are free from curtains, blinds, 
furniture, etc.

■

The outside temperature is below 65°F (18°C). Do not try to 
operate your air conditioner in the cooling mode when the 
outside temperature is below 65°F (18°C).

■

The temperature of the room you are trying to cool is 
extremely hot. Allow extra time for the air conditioner to cool 
off a very hot room.

■

Windows or doors to the outside are open. Close all 
windows and doors.

■

The Exhaust control is set to Open. Push the Exhaust 
control Closed for maximum cooling.

■

The Temp control is not at a cool enough setting. Adjust 
the Temp control to a cooler setting by pressing the minus 
button to reduce the temperature. Set the Fan Speed control 
to the highest setting.

■

The air conditioner in the heating mode has insufficient 
Btu/h for the heating requirements of the room. Do not 
use the air conditioner as a primary source of heat.

■

The air conditioner is not properly leveled. The air 
conditioner should slope slightly downward toward the 
outside. Level the air conditioner to provide a downward 
slope toward the outside to ensure proper drainage. See the 
Installation Instructions. 

NOTE: Do not drill a hole in the bottom of the metal base and 
condensate pan.
