CONNECT CONDENSATE DRAIN LINE
A condensate drain line is required to be fitted to carry discharge clear of
the water heater.
The condensate drain line should not be connected to the PTR drain line
but can exit to the same point.
The diagram shows the condensate drain location on the heat pump.
Independent 15mm copper pipes MUST be fitted to the drain outlets of the
PTR and ECV.
Each pipe MUST be open to atmosphere and run with a continual
downward grade in a frost free environment to a visible discharge point.
Drain lines MUST not exceed 9 meters in length.
Valves or other restrictions MUST NOT be placed in the relief valve drain outlet line.
ELECTRICAL TESTS
DO NOT turn on the power supply to the appliance until it has been filled with water and a satisfactory insulation
(Megger) test has been performed.
Conducting Insulation (Megger) Tests
When conducting an insulation test using a Megger on this appliance, observe the following:
This appliance contains electronic components, when performing insulation tests (500 Volts)
this MUST ONLY be conducted the across active terminal to earth and then across the neutral
terminal to earth.
WARNING
Tests between the active to neutral terminals MUST NOT be performed as this WILL damage
the electronic components.
Insulation test results of between 100 kΩ and 660 kΩ are normal for this appliance.
In accordance with AS/NZS 3000 an insulation test with a result less than 1 MΩ is permitted where the appliance
is approved to a Standard applicable to that class of appliance.
This appliance is categorised and certified as a 'stationary Class 1 motor operated appliance' and therefore
satisfies the requirements of AS/NZS 60335.2.40 for leakage current and electric strength. As such, this appliance
complies with the insulation resistance requirements of AS/NZS 3000.
ELECTRICAL CONNECTIONS
The power supply to the heat pump module MUST NOT be activated until the system is filled
with water.
WARNING
The premises wiring to the heater MUST be capable of withstanding the appliance load. Refer to
specification table for load details.
All electrical connections and wiring MUST be installed, maintained and removed by authorised
persons in accordance with AS/NZS 3000, and all other relevant local regulations and municipal
building codes including OH&S requirements.
The Heat Pump is fitted with a power cord & 15 Amp plug, it MUST connect to an independent,
fused, AC 240V 50 Hz power supply with an isolating switch installed at the switch board, which
shall effectively isolate all active supply conductors from the circuit and a means for disconnection
IMPORTANT
MUST be incorporated in the fixed wiring in accordance with the wiring rules.
A Residual Current Circuit Breaker is recommended for the power supply to this appliance (this
may be a mandatory requirements in some states or jurisdictions).
Disconnect all power prior to installation and commissioning.
This appliance is designed for single phase 240 Volts, AC mains electrical operation.
