Installation EDUS391000-F12 8. Installation Read these SAFETY CONSIDERATIONS for Installation carefully before installing an air conditioner or heat pump. After completing the installation, make sure that the unit operates properly during the startup operation. Instruct the customer on how to operate and maintain the unit. Inform customers that they should store this Installation Manual with the Operation Manual for future reference. Always use a licensed installer or contractor to install this product.
EDUS391000-F12 parts other than those specified by Daikin are used, fire or explosion may occur. CAUTION • Do not touch the switch with wet fingers. Touching a switch with wet fingers can cause electric shock. • Do not allow children to play on or around the unit to prevent injury.
Installation 2. EDUS391000-F12 FOR THE FOLLOWING ITEMS, TAKE SPECIAL CARE DURING CONSTRUCTION AND CHECK AFTER INSTALLATION IS FINISHED. BEFORE INSTALLATION WARNING • Entrust installation to the place of purchase or a qualified serviceman. Improper installation could lead to leaks and, in worse cases, electric shock or fire. • Use of unspecified parts could lead to the unit falling, leaks and, in worse cases, electric shock or fire. NOTE • Be sure to read this manual before installing the indoor unit.
EDUS391000-F12 Installation • Where piping between indoor and outdoor units is possible within the allowable limit. (Refer to the installation manual for the outdoor unit.) • If a return-air duct is not installed, carefully select the place and method of product installation so that air flow into the product will not be blocked. WARNING • When installing the unit horizontally, be sure to tilt the unit in the direction shown in Fig. 1-2. If the unit is tilted in any other way, water can leak.

Failing to insulate the pipes may cause leaking or burns.
Installation EDUS391000-F12 (1) Install drain piping as described Fig. 6. CAUTION • Be sure to insulate any field piping all the way to the piping connection inside the unit. Any exposed piping may cause condensation or burns if touched. In case of vertical installation • When brazing the refrigerant piping, perform nitrogen replacement first, or perform the brazing while feeding nitrogen into the refrigerant piping. (Refer to Fig.
EDUS391000-F12 Installation • To keep the piping from becoming clogged with dirt, avoid bends where possible and install so that traps can be cleaned. Air handler At least 4 in. At least 3 in. Fig. 7 • Observe the following guidelines when installing concentrated drain piping. Select the thickness of the concentrated drain piping to reflect the capacity of the machine to which it will be connected. (Install a drain trap for each indoor unit.) (Refer to Fig.
Installation EDUS391000-F12 NOTES 1. If the wiring is in a place where people it can be easily touched by people, install a ground-fault circuit interrupter to prevent electric shock. 2. When using a ground-fault circuit interrupter, make sure to select one useful also to protection against overcurrent and short-circuit. When using a ground-fault circuit interrupter only for grounding device, make sure to use a wiring interrupter together.
EDUS391000-F12 Installation in Fig. 10. • Then secure them in place with the included clamp material (1) as shown in Fig. 10 to protect them from external force from outside the unit. • If the power supply voltage is 208V, change the transformer wire connection from the 240V terminal to the 208V terminal. (Refer to Fig. 11) How to use insulation tube. • Use the insulation tube to cover the wiring. • Joint the insulation tube with the tape and cut off the tube sticking out of the unit.
Installation EDUS391000-F12 • Outside the air conditioners, separate the low voltage wiring (remote controller and transmission wiring) and high voltage wiring (ground wire and power supply wiring) by at least 5 in. so that they do not pass through the same place together. Proximity may cause electrical interference, malfunctions, and breakage. [ PRECAUTIONS ] • Refer to the “REMOTE CONTROLLER INSTALLATION MANUAL” on how to install and lay the wiring for the remote controller.

EDUS391000-F12 Installation (1) Turn off power supply to all indoor and outdoor units. (2) Remove the front panel (upper) and the electric heater slot cover. (5) Install the circuit breaker mounting bracket removed in step (3) into the blower deck. * The HKR-03 and HKR-06 have no circuit breaker mounting bracket; Procure and install a circuit breaker. Electric heater slot cover (6) Connect the relay connector of the heater kit to the relay connector of the product.
Installation EDUS391000-F12 (8) Pass the power supply wiring and the ground wire through the conduit (conduit should be field supplied). The hole for running wires through should be sealed completely to prevent air from entering. (11) Confirm that there are no mistakes with the wiring, and install the front panel (upper).
EDUS391000-F12 Installation (12) -2 Electric heater operating mode setting 〈When electric heater is used in “Heat Pump lockout mode”〉 • Check the heater capacity. (Select heater marked with “ ” or “ 2” in Table 8.) • Perform on-site setting using the remote controller. • Set the “heat pump lockout mode” using the outdoor unit.
