Page 7: Indoor Unit Installation
Indoor unit installation Refrigerant pipe work must be done before installing the indoor unit. Location Access for servicing is an important factor in the location of any air handler. Provide a minimum of 30 inches in front of the appliance for access to the control box, heating elements, blower and air filters. This access may be provided by a closet door or by locating the appliance so that a wall or partition is not less than 30 inches from the front access panel. - Page 8 Indoor unit installation This appliance is approved for zero (0) inches clearance to combustible material on any part of the air handler exterior casing and the inlet or outlet ducts providing NO electric heater is being used. There is a one (1) inch clearance on the supply plenum and supply air duct when an electric heater is installed in the appliance.
- Page 9 Indoor unit installation Return air requirements Closet Wall Typical Closet Installations Provisions shall be made to permit the air in the rooms and the living spaces to return to the air handler. Failure to comply may cause a reduction in the amount of return air available to the blower, causing reduced air flow resulting in improper heating and cooling of the living space.

Page 10: Upflow Application
Indoor unit installation Arrangement: Unit is shipped from the factory arranged to be installed in an upflow or horizontal left (right to left air flow) position. Horizontal left means when the unit is laid on its side and you are facing the unit, the supply air opening is to the left and the return opening is to the right. -
Page 11: Horizontal Application
Indoor unit installation Horizontal application Horizontal applications will normally be used in an attic or crawl space. This type of installation requires supply air plenum or duct to be connected to the supply collar and a return air plenum or duct be attached to the unit inlet collar. -

Page 13: Performing Leak Test & Insulation
Performing leak test & insulation Leak test LEAK TEST WITH NITROGEN (before opening valves) In order to detect basic refrigerant leaks, before recreating the vacuum and recirculating the R-410A, it’s responsible of installer to pressurize the whole system with nitrogen (using a pressure regulator) at a pressure above 595 PSI (4.1MPa). LEAK TEST WITH R-410A (after opening valves) Before opening valves, discharge all the nitrogen in the system and create vacuum. - Page 14 Performing leak test & insulation 5. Select the insulation of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. Indoor temperature of 86 °F(30 °C) and humidity of 85% is the standard condition.If install in a high humidity condition,use one grade thicker insulator by referring to the table below.If installing in an unfavorable conditions, use a thicker wall insulation.
