Outdoor Unit Installation - Daikin FT18HEV1K Operation Manual And Installation Manual

Outdoor unit installation

1. Remove the handle from the outdoor unit's right side plate.
2. Remove the cord anchorage. Connect the power cord
(for cooling and heating unit, connect the power cord
and signal control wire) to the terminal block.
3. Attach the power cable with the cord anchorage,
(for cooling and heating units, use the cord anchorage
to attach the power cable and the signal control wire).
4. Make sure the wire is securely connected.
5. Install the handle.
NOTE:
● Incorrect wiring can cause parts to malfunction.
● After the cable is connected, make sure there is space between the connection and the
place where the lead wire is attached.
1. Connect the charging hose on the manifold valve to the charge end of the low pressure
valve (both high/low pressure valves must be tightly shut).
2. Connect charging hose joint to vacuum pump.
3. Turn the handle and open the Lo manifold valve completely.
4. Open the vacuum pump to release the air. Slowly loosen
the joint nut on the low pressure valve to check for air
leakage. (If the vacuum pump noise changes, the
multimeter reading will be 0.) Tighten the nut.
5. Release the pressure for 15 minutes or more and
make sure the multi-meter reading is 1.0 × 10
(–76cmHg).
6. Fully open high/low pressure valves.
7. Remove charging hose from charging end of low pressure valve.
8. Tighten the bonnet on the low-pressure valve. (As shown in Fig.10)
Drain of condensation from the outdoor unit (Heat pump models)
Condensed water that forms during heating must be properly
discharged through the drainage pipe.
Installation method: Put the drain connection through
the 25mm hole in the frame and connect the drainage pipe to
the drain nozzle.
