Whether you're installing a new Hitachi system or have an older one that keeps tripping, the electrical side is our job: the circuit, the isolator at the outdoor unit and the protection at the switchboard.

Hitachi split and ducted systems are installed in homes around Sydney, and some have been running for many years. That means our Hitachi work is a mix of new connections and checking older installations whose isolators, cables or protection are showing their age.
For a new system, the refrigeration technician installs the units and handles the refrigerant (an ARC-licensed task we never do). We provide the dedicated circuit, outdoor isolator and switchboard protection, then test and certify. For an older system, we test the existing circuit and tell you honestly whether the problem is electrical or in the unit.
Blue Link Electrical is a licensed electrician based in Hurlstone Park (licence 332956C), working across the Inner West and Sydney.
Hitachi sells wall splits and ducted systems in Australia. As with any brand, the supply a unit needs depends on its capacity and type, and the installation manual is the document that settles it: supply requirements, recommended protection and where the power terminates.
If you're replacing an old Hitachi with a new one, don't assume the existing circuit is fine. Older installations sometimes predate safety switch protection on that circuit, use an isolator that has degraded in the sun, or were sized for a smaller unit. We check all three and quote anything that needs bringing up to date.
Each fixed system on its own appropriately sized circuit. See air conditioner dedicated circuits.
A sound, sealed, outdoor-rated isolating switch next to the condenser. Old ones are often due for replacement.
RCD protection on the circuit, often by an RCBO. Older installations may not have it.
Cable and breaker checked against the new unit's manual, not just carried over from the old one.
Room on the board and capacity in the main supply for the load.
1. Inspect. We look at the Hitachi model and manual, the switchboard and, for replacements, the existing cable and isolator.
2. Upgrade or install. New circuit and protection where needed, or reuse of a suitable existing circuit after testing.
3. Isolate and connect. Isolator fitted or replaced and supply connected. The refrigeration technician commissions the system.
4. Test and certify. Testing to AS/NZS 3000, with a Certificate of Compliance for Electrical Work.
Could be water in the isolator, a deteriorated cable or an internal fault. We test the electrical side; unit faults go to Hitachi's service network or your air conditioning technician.
Years of sun make plastic housings brittle. Replace it before it lets water in.
Some older installations lack it. Adding protection is a good safety improvement. See RCD vs RCBO.
When the unit works hardest. Can point to an undersized circuit, loose connections or a unit fault.
We test the circuit and isolator first. If they're fine, the fault is in the unit, and an air conditioning technician can advise whether repair makes sense.
Only if the cable, protection and isolator suit the new unit's manual and are in good condition. We test before reusing.
No. An ARC-licensed refrigeration technician installs the units and handles refrigerant. We do the electrical connection.
There's no fixed interval. Replace it when the housing is cracked, faded and brittle, or water has got in.
