Daikin Tools for Install


750 – 1000 PSI

Additional Tools for Install• Metric tools (hex key set and socket set) are required when

installing or servicing Daikin RLC units• Nitrogen regulator capable of measuring up to 700 plus PSI is

necessary for installing Daikin RLC units

Metric Hex Key Set

Metric Socket Set


• Compatible with all HFC Refrigerants• Excellent anti‐wear properties• Better solubility with process fluids• Superior Resistance to Cap tube blockage• Better lubricity• Optimal for non‐drier systems• Very Hygroscopic but with no hydrolysis• Moisture easily removed

• Label the indoor units A, B, C, D, etc. as appropriate

• Daikin does not have preference regarding install order

• Important for wiring and piping

• Piping and wiring must match

• If the system is piped A, B, & C then it MUST be wired A to A, B to B, and C to C, etc.

• Fully supported in a location with little or no vibration

• Easily accessible with adequate space for servicing or repairs

• Placed within distance of allowable pipe length

• Located away from items producing heat or steam (gas)

• Located in a well‐ventilated area; not installed in a location that is hot

or humid for long periods of time (DB temp of 140° or above)

• Not installed near bedrooms due to possible audible sounds of

refrigerant flow through the piping

Electrical Wiring


Electrical WiringThe outdoor unit and branch provider (BP) units operate from separate 208/230V single‐phase power supplies, eliminating the need of power supply between them. Therefore, wiring size from the outdoor unit to the branch provider (BP) units can be reduced and ease installation.

Refrigerant Piping


Install Guidelines

• When connecting a pipe to the unit body or

removing it, be sure to use a back up wrench

and torque wrench.

• For the work dimension and the tightening

torque of the flare section, see this table.

• When connecting a flare nut, apply oil to the

flare section (only the OUTER surface), and

screw the nut three or four times initially by

hand.

• Be sure to use the flare nuts included with

the condenser or fan coil.

Test Operation

Remaining System Field Settings

Verify system operation in Cool & Heat mode as outside ambient temperature

conditions allow (heat mode is prohibited above 75.2°F outside air temperature)


Operating TestFollow the “Operating Test” as described in the installation manual of the outdoor unit. If BP unit does not operate normally during the test run, the error can be checked on the remote controller display for the indoor unit.

Simple diagnosis can be done using the LEDs on the BP unit’s circuit board.For details, see the label on the inside of the BP unit’s electrical wiring unit cover.

*DO NOT perform any other procedures during Operating Test*Operating Test CANNOT be performed during: initialization, additional charge, or recovering mode

E2 Printed circuit board faulty (BP unit)

J0 Liquid and gas thermistor faulty (BP unit)

U4 Transmission error between BP unit and indoor unit

Correctly connect the inter connections between BP unit and indoor unit

U9 Transmission error between outdoor unit and BP unit

Correctly connect the inter connections between outdoor unit and BP unit


Operating Test

Power On – Check Operation

Insure all thermisters and transducers are in place

Power ON outdoor unit for 6 hours (crank case heater)

Power ON branch port units

Open Service Valves

Perform check operation

Press/Hold BS4 (Test) button for 5 seconds


Operating Test

Temperature Control – Check Operation

Makes sure the indoor and outdoor units are operating normally

Run each indoor unit one at a time and make sure the outdoor unit is also

running

Check to see if cold (or hot) air is coming out of the indoor unit

Press the fan direction and fan strength buttons on the indoor unit to see

if they operate properly
