INDOOR UNIT INSTALLATION STEP 1: SELECT INSTALLATION LOCATION Before installing the indoor unit, you must choose an appropriate location. The following standards should be met for an appropriate location for the unit: • • • • • • Good air circulation Convenient drainage Noise from the unit will not disturb other people Firm and solid - the location will not vibrate Strong enough to support the weight of the unit A location at least three feet (one meter) from all other electrical devices (e.g.
STEP 2: HANG INDOOR UNIT 1. Refer to the following diagrams for unit dimensions and locations for the four suspension bolt holes required to hang the indoor unit.
2. Before drilling the holes in the ceiling and mounting the unit, align the refrigerant pipes, drain pipe, and electric cable connection points with the direction they will be drawn out and connected to the outdoor unit through the wall hole (see Step 3: Drill Wall Hole For Connective Piping). 3. Drill four holes 4" deep in the internal ceiling for each of the required suspension bolt anchors (field supplied). Make sure to hold the drill at a 90o angle to the ceiling. 4.
STEP 4: DUCT AND ACCESSORIES INSTALLATION Once the unit is hung, you may install any additional ducting required. The diagram below illustrates one example of installing the unit with hidden ducting. The unit may also be installed exposed, depending on your needs. Vibration Dampener Vibration Dampener Duct Plenum Air Inlet Air Outlet Plenum Access Panel Air Filter INSTALLATION TIPS • • • • • • Air filters help remove dust and particles from the circulating air.
2. Bend the rear ventilation panel 90o along the dotted line (some models). 3. Swap the mounting positions of the ventilation panel and air return flange. 4. Install the filter mesh. Insert into flange as illustrated below. Ventilation panel Air return flange Or Ventilation panel Air return flange FRESH AIR DUCT INSTALLATION This unit allows for a fresh air duct to be installed. Duct location and dimensions are shown below. Fresh air duct joint DRAD18F1A & DRAD24F1A DRAD09F1A & DRAD12F1A Ø3.
MAINTENANCE ACCESS PANEL If this unit is located in a sub-ceiling, an access panel should be installed in order to gain access to the unit for routine maintenance. Common maintenance items are shown below for consideration when designing panel size and location. A minimum panel size of 2' x 2' is recommended.
4. This unit is equipped with a drain pump that allows the outlet of the drain pipe to be higher than the pipe's connecting port. For pump assisted draining, install the drain pipe to the upper connecting port. The vertical lift pipe must be installed no higher than 21 5/8" (550mm) from the drain connection port with a maximum distance of 7 7/8" (200mm) between the unit and the lift pipe. To prevent air bubbles, make sure the pipe between the unit and the lift pipe is level or slightly tilted up (0 - 1").
STEP 6: CONNECT SIGNAL CABLE BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS 1. All wiring must comply with local and national electrical codes and regulations, and must be installed by a licensed electrician. 2. All electrical connections must be made according to the Electrical Connection Diagram located on the panels of the indoor and outdoor units. 3. If there is a serious safety issue with the power supply, stop work immediately and contact a licensed electrician.
Choose the correct size of cable The size of the power supply cable, signal cable, fuse, and switch needed is determined by the maximum current of the unit. The maximum current is indicated on the nameplate located on the side panel of the unit. Refer to this nameplate to choose the right cable, fuse, or switch. Wiring the Indoor Unit 1. Prepare the cable for connection: • Using wire strippers, strip the jacket from both ends of the cable to reveal about 6" of the wires.
STEP 7: PREPARE REFRIGERANT PIPING 1. If pre-existing refrigerant piping is already embedded in the wall, begin the outdoor unit installation. Refer to the Refrigerant Piping Connections section of the outdoor unit's installation manual for detailed instructions. 2. If there is no pre-existing piping, connect the indoor unit’s refrigerant piping to the connective piping that will join the indoor and outdoor units.
TROUBLESHOOTING SAFETY PRECAUTIONS If ANY of the following conditions occurs, turn off your unit immediately! • The power cord is damaged or abnormally warm • You smell a burning odor • The unit emits loud or abnormal sounds • A power fuse blows or the circuit breaker frequently trips • Water or other objects fall into or out of the unit DO NOT ATTEMPT TO FIX THESE YOURSELF! CONTACT AN AUTHORIZED SERVICE PROVIDER IMMEDIATELY! COMMON ISSUES The following problems are not a malfunction and in most situations
