Installation method for prevention of falling overIf it is necessary to prevent the unit from falling over, install as shownin the figure. prepare all 4 wires as indicated in the drawing unscrew the top plate at the 4 locations indicated A and B put the screws through the nooses and screw them back tightA Location of the 2 fixation holes on the front side of the unitB Location of the 2 fixation holes on the rear side of the unitC Wires: field supply6.3. Drain pipe disposal Make sure the drain works properly. In regions where buildups of snow can be expected, theaccumulation and freezing of snow in the space between theheat exchanger and external plate may lower operatingefficiency. In this case, drill a knock-out hole in the lower part ofthe bottom frame so the snow can escape. When creating aknock-out hole, use a Ø6 mm drill bit to open round holesconnected to the circumference of the knock-out hole (4 places). After punching the knock-out hole, the application of repair-typepaint on the surface around the edge sections is recommendedto prevent rust.7. Installation service space The installation service spaces shown in the illustrations arebased on an air intake temperature of 35°C (DB) for COOLoperation. In regions where the air intake temperature regularlyexceeds 35°C (DB), or if the heat load of outdoor units isexpected to regularly exceed the maximum operating capacity,reserve a larger space than that indicated at the air intake sideof units. Regarding the required air outlet space, position the units withconsideration to the space required for the onsite refrigerantpiping work as well. Consult your dealer if the work conditions donot match those in the drawings.7.1. Precaution on installation(A) In case of non-stacked installation (See figure 1) (Unit : mm)(A-1) Single unit installation(A-2) Multiple units installation (2 units or more)- Secure appropriate space when using a side piping outlet.(B) In case of stacked installation1. In case obstacles exist in front of the outlet side.2. In case obstacles exist in front of the air inlet. Do not exceed two levels for stacked installation. Install a roof cover as shown in the figures above (field supply),as outdoor units with downward drainage are subject to drippingand freezing of that drain water. Install the upper outdoor unit so that its bottom plate is atsufficient height above the roof cover. This is to prevent thebuildup of ice on the bottom plate outer surface. A space of atleast 500 mm is recommended. It is not necessary to install a roof cover if there is no danger ofdrainage dripping and freezing. In this case, the space betweenthe upper and lower outdoor units should be at least 100 mm.Close the gap between the upper and lower units so there is nore-intake of discharged air.(C) In case of multiple-row installation (for roof top use, etc.)1.
