Use 220 to 240 V AC power. Failuretoheadthiswarningmayresultinfire,electricshockordamagetothecircuitboards.For the outdoor air intake vent, choose a position where combustion gas or other similar exhaust air is not sucked in and the vent is not buried by snow.Inabilitytobringinfreshairmayresultinlackofoxygenintheroom.Select a place which is strong enough to support the product, and install the product securely.Injurycouldresultifpartsfall.Electrical work must be carried out safely and reliably by a professional electrical contractor (properly qualified electrician) in accordance with internal wiring provisions and electrical-equipment technical standards.Poorconnectionandfaultyelectricalworkcouldresultinelectricshockorfire.Install an all-pole power supply isolator at the power supply side as per local electrical regulations. All supply circuits must be disconnected before obtaining access to the terminal devices. Use the specified cable size and connect the cables securely to prevent disconnection when they are pulled.Ifthereisadefectintheconnection,thereisapossibilityoffire.Use the designated electric wires, and connect them securely so that they do not come loose.Defectiveconnectionsmayresultinfire.When metal ducts penetrate through metal-sheeted wooden buildings or structures, install the product so that there is no electrical contact between the metal ducts and the metal sheeting.Electricleakagemaycauseignition.Make sure to cover with the terminal block cover after electrical work.Failuretoheedthiswarningmaycausedust,humidity,etc.toenter,resultinginelectricleakageorfire.Secure duct piping with commercially available fixing bands, aluminum tape, etc. to prevent piping from coming loose. Install outdoor piping from the product so that it is tilted at a downward pitch of at least 1/30 towards the outside.Failuretoheedthiswarningmaycauserainpenetration,resultinginelectricshock/fireorwaterdamagetohouseholdproperty.Piping should be installed so that no load is applied to the pipe guide.Failuretoheedthiswarningmaycausedampermulfunction.If the product will not be operated for a long period of time after installation, make sure to turn off the circuit breaker.Itcouldcauseelectricalshockbydeterioratedinsulationorfirebytheelectricleakage.

4.4.2 Insulating the Ducts
CAUTIONTo prevent dew condensation, insulate the ducts and pipe guide. (glass wool 25 mm or equivalent) Make sure to insulate up to the base of pipe guide.When the product is anticipated to be stopped for a long time, insulate the RA (Return Air) side ducts also. (i.e. not operated for 24 hours).Indoor humidity can cause condensation because exposed parts can become cold in winter.
