For Preparation of Heating
"HOT KEEP"is operated in the following cases.
When heating is started:
In order to prevent blowing out of cool wind, the indoor unit fan stopped
according to the roo piping te perature when heating operation is started.
Wait for approx. 2 to 3 inute, and the operation will be auto atically changed
to the ordinary heating ode.
Defrosting operation (in the heating ode):
When it is liable to frost. the heating operation is stopped auto atically
for 5 to 12 inutes once per approx. one hour, and defrosting is operated.
After defrosting is co pleted, operation ode is auto atically changed
to ordinary heating operation.
When the roo ther ostat is actuated:
When roo te perature increases and roo te perature controller actu-
ates, the fan speed is auto atically changed to stop under low te perature
condition of indoor heat exchanger. When roo te perature decreases,
air conditioner auto atically changes over to ordinary heating operation.
WARMING OPERATION

Period of war -up
With the heat pu p type war ing, the echanis of heat pu p that concentrate heat of outdoor
air with the help of refrigerant to war the indoor space, is utilized.
When a roo is war ed with a heat pu p type air conditioner, frost accu ulates on the heat ex-
changer of outdoor unit along with the drop of indoor te perature. Since the accu ulated frost re-
duces the effect of war ing, it is necessery to auto atically switch the operation to the defrosting
ode. During the defrosting operation, heating operation is interrupted.
War ing capacity of heat pu p type air conditioner decreases along with the
drop of outdoor te perature.
When the war ing capacity is not sufficient, it is reco ended to use another
heating i ple ent.
Since the heat pu p type air conditioner e ploys a ethod to circulate war
winds to war the entire space of a roo , it takes ti e before the roo te -
perature rises.
It is reco endable to start the operation a little earlier in a very cold orning.

1. Safet precautions
WARNING
Please read these "Safety Precautions" first then accurately execute the installation work.
Though the precautionary points indicated herein are divided under two headings,
and , those points which are related to the strong possibility of an installation done in error
resulting in death or serious injury are listed in the section. However, there is also a
possibility of serious consequences in relationship to the points listed in the section as well.
In either case, i portant safety related infor ation is indicated, so by all eans, properly observe all that is
entioned.
After co pleting the installation, along with confir ing that no abnor alities were seen fro the operation
tests, please explain operating ethods as well as aintenance ethods to the user (custo er) of this equip ent,
based on the owner's anual.
Moreover, ask the custo er to keep this sheet together with the owner's anual.
This syste should be applied to places as office, restaurant, residence and the like. Application to inferior
environ ent such as engineering shop could cause equip ent alfunction.
Please entrust installation to either the co pany which sold you the equip ent or to a professional contractor.
Defects fro i proper installations can be the cause of water leakage, electric shocks and fires.
Execute the installation accurately, based on following the installation anual. Again, i proper installations
can result in water leakage, electric shocks and fires.
When a large air-conditioning syste is installed to a s all roo , it is necessary to have a prior planned
counter easure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration.
In regards to preparing this counter easure, consult with the co pany fro which you perchased the equip ent,
and ake the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold
concentration does occur, there is the danger of a resultant oxygen deficiency accident.
For installation, confir that the installation site can sufficiently support heavy weight. When strength is
insufficient, injury can result fro a falling of the unit.
Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons
and hurricanes, etc. I proper installations can result in accidents due to a violent falling over of the unit.
For electrical work, please see that a licensed electrician executes the work while following the safety standards
related to electrical equip ent, and local regulations as well as the installation instructions, and that only
exclusive use circuits are used.
Insufficient power source circuit capacity and defective installation execution can be the cause of electric
shocks and fires.
Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted
to the ter inal connection part, through properly securing it. I proper connection or securing can result in
heat generation or fire.
Take care that wiring does not rise upward, and accurately install the lid/service panel. Its i proper installation
can also result in heat generation or fire.
When setting up or oving the location of the air conditioner, do not ix air etc. or anything other than the
designated refrigerant within the refrigeration cycle.
Rupture and injury caused by abnor al high pressure can result fro such ixing.
Always use accessory parts and authorized parts for installation construction. Using parts not authorized by
this co pany can result in water leakage, electric shock, fire and refrigerant leakage.
CAUTION
