As a rule, the unit cannot be installed at a height of less than 8. 3ft(2. 5 m). It is possible to install the unit at a height of between 7. 3~8. 3ft(2. 2~2. 5m) from the ground, if the unit has a duct with a well defined length (11. 81inch(300mm) or more) to avoid fan motor blower contact.

Note Since the diagram is made of paper, it may shrink or stretch slightly due to temperature or humidity. For this reason, before drilling the holes maintain the correct dimensions between the markings. Concrete Insert 2 Insert bolt anchors, use existing ceiling supports or construct a suitable support as shown in figure. Hole in anchor Hole in plug Suspension bolt(3/8" or M10) Ceiling support 3 Install the suspension bolts depending on the ceiling type. Ensure that the ceiling is strong enough to support the weight of the indoor unit. Before hanging the unit, test the strength of each attached suspension bolt. If the length of suspension bolt is more than 4. 94ft(1. 5m), it is required to prevent vibration. If this is not possible, create an opening on the false ceiling in order to be able to use it to perform the required operations on the indoor unit.

When contacting the gas side and liquid side pipe, use 1 grade thicker insulator. Gas pipe Liquid pipe Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering. Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight. Install the refrigerant pipe respecting that the insulation does not get thinner on the bent part or hanger of pipe. Add the additional insulation if the insulation plate gets thinner.

The connection port of the flexible hose and PVC drainpipe must be fixed with PVC adhesives. Check out that the connected part doesn't leak. Drain pipe type : VP25(AVXC4/ND4H) 2 Connect the flexible hose to the drain hose port. Make sure that a rubber ring is installed on the drain hose port. Drain hose port location differs depending on the unit types. 3 Install the drain pipe as shortly as possible. Give a slightly slant to the drainpipe for proper drainage of condensate water. There must be no gap on the connected part so that the drainpipe is not separated from the flexible hose.
