ROUTINE MAINTENANCE
Cleaning of exterior, interior, and accessories
Use a dry cloth to wipe down the outside and inside of the unit and all accessories. If the outside panels
are dirty, wipe the panels using a cloth moistened with a diluted neutral dish-washing detergent.
Wipe off condensation from the glass or exterior of the cabinet with a dry, soft cloth.
Using an undiluted solution of detergent may cause the unit’s plastic areas to crack. Follow the
directions on the detergent for details of dilution.
After wiping the cabinet or accessories with a diluted detergent, be absolutely sure to wipe the surfaces
with a cloth dipped in clean water to remove traces of the detergent. After this, be absolutely sure to
wipe the surfaces with a dry cloth.
<Important>
Do not use a brush, an acid, a thinner, laundry soap, a powder detergent, or boiling water for cleaning.
These may cause damage to painted surfaces or cause perishing of plastic and rubber components.
Moreover, do not wipe plastic and rubber components with a volatile material.
In order to maintain the unit’s intended level of performance, always replace accessories that have
been removed for cleaning.
Checking of alarm operation
Check the alarm operation regularly (every 6 months) to ensure that the alarm is activated in case of
power failure. The alarm operation can be checked by following the procedure below.
1.
Press the alarm test key (ALARM TEST).
2.
The alarm indicator blinks, the alarm buzzer sounds intermittently, and the remote alarm is in alarm
mode. This continues for 90 seconds and then finishes automatically.
During the 90 seconds, the alarm buzzer cannot be stopped by pressing the alarm buzzer stop key
(BUZZER).
3.
The alarm operation can be cancelled by pressing the alarm test key (ALARM TEST) again during the
90 seconds.
Cleaning of condenser filter
The condenser filter is installed inside the front cover. Clean the condenser filter every 6 months to
maintain the appropriate cooling performance.
1.
Open the front cover by pulling firmly on both lower
corners of the front cover. [Fig. 1]
2.
Raise the shaft, and insert the end of the shaft into the
black hole in the front cover. This keeps the front cover
from falling back.
3.
Gently pull the black tab on the lower middle of the
condenser filter to remove the condenser filter.
4.
Clean the condenser filter with a vacuum cleaner or
water.
5.
Thoroughly dry the condenser filter when using water to clean it.
