• Corresponding language table ................................. 102 Contents Thank you for purchasing this Panasonic product.This product is a commercial air conditioner indoor unit.Installation Instructions attached. Conrm to authorized dealer or specialist on usage of specied refrigerant type. Using of refrigerant other than the specied type may cause product damage, burst and injury etc. This air conditioner has no ventilator for intaking fresh air from outdoors. You must open doors or windows frequently when you use gas or oil heating appliances in the same room, which consume a lot of oxygen from the air. Otherwise there is a risk of suffocation in an extreme case. Never use or store gasoline or other ammable vapor or liquid near the air conditioner — it is very dangerous. Do not use this appliance in a potentially explosive atmosphere. Never touch the unit with wet hands. Do not insert your ngers or other objects into the air conditioner indoor or outdoor unit, rotating parts may cause injury. If the refrigerant comes in contact with a ame, it produces a toxic gas. For safety, be sure to turn the air conditioner off and also to disconnect the power before cleaning or servicing. Pull off the power plug from a receptacle, or switch off the breaker, or switch off the power disconnecting mean to isolate the air conditioner from the main power supply in case of emergency. Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for cleaning. In case of malfunction of this appliance, do not repair by yourself. Contact the sales dealer or service dealer for a repair and disposal.

Before Requesting Services Troubleshooting Emergency Operation

If any of the following events should occur, operate the unit temporarily by pressing the Emergency button of the Indicator.

Remote controller is out of order. Battery is dead (in the case of using optional wireless remote controller). Remote controller is lost (in the case of using optional wireless remote controller). Pressing the Emergency button will operate under the following conditions.• Operation mode : AUTO • Set temperature : 24

• Fan speed : High ( , )At this time, the OPERATION lamp of the indoor unit's Indicator lights up.When stopping the emergency operation, press the Emergency button. CAUTION Do not keep pressing the Emergency button. If accidentally kept pressing the button, the unit will go into service mode. When the Emergency button is pressed once again, the unit returns to stop mode. If not returned to stop mode, consult the sales dealer or service center. IndicatorEmergency button OI_00_311238_EU.indb 10 2019/5/10 9:37:3611 ENGLISH Tips for Energy Saving

Do not block the air intake and outlet of the unit. (If either is obstructed, the unit will not function well, causing malfunction.) During cooling operation, use sunshades, blinds or curtains to prevent direct sunlight from entering the room.

zAlways keep the air lter clean. (A clogged lter will impair the performance of the unit.) → “Maintenance” (P.8) zTo prevent conditioned air from escaping, keep windows, doors and any other openings closed. Operation Mechanism

Heating performance zSince this air conditioner utilizes outside air for heating, its heating performance deteriorates as outside temperature decreases. (Due to heat pump system) →In that case, use another heating appliance.

Defrosting zThis appliance may start defrosting operation to melt frost formed in the outdoor unit.

Defrosting starts: The indoor unit fan stops (or the speed becomes extremely slow). ” (STANDBY) appears.

Heating operation resumes after several minutes: The indoor unit fan remains stopped (or it will run at a very slow speed) until the indoor heat exchanger coil warms up sufciently. ” (STANDBY) appears.

Defrosting is complete: The indoor unit fan starts operation. ” (STANDBY) disappears.

‘‘DRY’’ operation zOnce the room temperature reaches the level that was set, the outdoor unit repeats the cycle of turning on and off automatically. zWhen the room temperature is more likely to reach the level that was set, the fan speed is set to ‘‘breeze’’ (light wind) automatically. (To prevent the humidity in the room from rising again)
