Cautions
Checks to electrical devices
- Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a
fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt
with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall
be used. This shall be reported to the owner of the equipment so all parties are advised.
- Initial safety checks shall include:
• that capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
• that no live electrical components and wiring are exposed while charging, recovering or purging the system;
• that there is continuity of earth bonding.
Repairs to sealed components
- During repairs to sealed components, all electrical supplies shall be disconnected prior to any removal of sealed covers, etc. If
it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak
detection shall be located at the most critical point to warn of a potentially hazardous situation.
- Ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected,
including damage to cables, excessive number of connections, terminals not made to original specication, damage to seals,
incorrect tting of glands, etc.
- Ensure that the apparatus is mounted securely.
- Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of preventing the
ingress of ammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s specications.
Repair to intrinsically safe components
- Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the
permissible voltage and current permitted for the equipment in use.
- Intrinsically safe components are the only types that can be worked on while live in the presence of a ammable atmosphere.
- Replace components only with parts specied by the manufacturer. Other parts may result in the ignition of refrigerant in the
atmosphere from a leak.
Cabling
- Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as
compressors or fans.
Detection of ammable refrigerants Removal and evacuation
- The refrigerant charge shall be recovered into the correct recovery cylinders and the system shall be “ushed” with OFN to
render the unit safe. This process may need to be repeated several times.
- Compressed air or oxygen shall not be used for purging refrigerant systems.
- Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to ll until the working pressure is
achieved, then venting to atmosphere, and nally pulling down to a vacuum. This process shall be repeated until no refrigerant
is within the system. When the nal OFN charge is used, the system shall be vented down to atmospheric pressure to enable
work to take place.
- The vacuum pump is not close to any ignition sources and that ventilation is available.
Charging procedures
- Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as
short as possible to minimise the amount of refrigerant contained in them.
- Cylinders shall be kept upright.
- Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
- Label the system when charging is complete (if not already).
- Extreme care shall be taken not to overll the refrigeration system.
- Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The system shall be leak- tested on
completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.
Decommissioning
- Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail.
- Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re- use of
reclaimed refrigerant.
- Electrical power must be available before the task is commenced.

Parts and Functions
“HOT KEEP” function
“HOT KEEP” is operated in the following cases.
yWhen heating is started:
In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating
operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating
mode.
yDefrosting operation (in the heating mode):
When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour, and
defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating operation.
yWhen the room thermostat is actuated:
When room temperature increases and room temperature controller actuates, the fan speed is automatically changed to stop
under low temperature condition of indoor heat exchanger. When room temperature decreases, air conditioner automatically
changes over to ordinary heating operation.
Warming operation
yHeat pump type warming
With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of refrigerant
to warm the indoor space, is utilized.
yDefrosting operation
When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit along
with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to automatically
switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted.
yAtmospheric temperature and warming capacity
Warming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature. When the warming
capacity is not sufcient, it is recommended to use another heating implement.
yPeriod of warm-up
Since the heat pump type air conditioner employs a method to circulate warm winds to warm the
entire space of a room, it takes time before the room temperature rises.
It is recommendable to start the operation a little earlier in a very cold morning.
Maintenance
Clean the air lter
1. Pull the lters upward to remove them from the Intake Grill.
2. Clean the air lter: Remove the dust from the lters by vacuum cleaner or washing them.
After washing, allow the air lters to dry thoroughly in an area protected from sunlight.
3. Re-attach the air lters to the Intake Grill. Press the two buttons on the lters until you hear
a sound of click.
Maintenace of indoor units
yWhen used for extended periods, the unit may accumulate dirt inside, which reduces its performance. We recommend that
the unit is inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service
personnel.
yWhen cleaning the unit’s body, do not use water hotter than 40°C, harsh abrasive cleansers, or volatile agents like benzene or
thinner.
yDo not expose the unit body to liquid insecticides or hairsprays.
yWhen shutting down the unit for one month or more, rst allow the Fan mode to operate continuously for about half a day to
allow internal parts to dry thoroughly.

Troubleshooting
Followings are not problems
Sound of water owing is not a problem. During unit operation or at stop, a swishing or gurgling noise may be heard. This
noise is generated by refrigerant owing in the system.
Sound of cracking is heard. During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or shrinking because of temperature
changes.
Smell are generated. This is because the system circulates smells from the interior air such as the smell of
cigarettes or the painting on the furniture.
During operation, white fog or steam
comes out from the indoor unit.
When unit is running at places like restaurant, etc. where dense edible oil fumes
always exist, this will happen.
In cooling operation, unit switches to
blowing operation.
To prevent frost from accumulating on indoor heat exchanger, unit will switch to
blowing operation for a while then resume cooling operation.
Unit will not restart after stop.
Won’t start?
Though ON/OFF button is set to ON, the unit won’t resume cooling, dry or heating
operation in 3 min after it is stopped, this is because of 3-min-delay protection circuit.
Please wait 3 minutes
No outlet air or fan speed can’t be
changed in dry mode.
Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry
operation.
In heating operation, water or steam r are
blown out of outdoor unit.
This occurs when frost accumulated on the outdoor unit is removed.
(during defrosting operation)
In heating operation, indoorfan won’t stop
even if unit is stopped.
After unit stop, indoor fan will go on running until indoor unit cools down.

heating mode)?
Any doors or windows left open?
Poor cooling
Is there any direct sunlight in the room? If there are unexpected heat sources in the
room?
Too many people in the room?
Cold air blows out (in heating mode). Is air conditioner in standby condition in heating mode?
If your unit still can’t work properly after above mentioned checks, or following problems occur, please stop it immediately and
contact your dealer.
