Page 4: Safety Precautions
If you can't make sure that your house power supply is earthed well, please don't install the unit. The unit must be installed by a licensed tradesperson and in accordance with： Midea installation instructions. ● AS/NZS 3500.4-"National Plumbing and Drainage Code Hot Water Supply ●...
Page 5 NOTE This water heater must be installed by a licensed person as required by the Building Act. Only a licensed person will give you a compliance certiﬁcate, showing that the work complies with all the relevant standards and only a licensed person will have insurance protecting their workmanship for 6 years.
Page 6 BATTERY DISPOSAL Dispose of used button/coin batteries immediately. ● Place sticky tape around both sides of the battery and dispose of it immediately ● in an outside bin, out of reach of children, or recycle safely. HOT WATER CAN BE DANGEROUS Warning –...
Page 7 EXPLANATION OF SYMBOLS DISPLAYED ON THE INDOOR UNIT OR OUTDOOR UNIT This symbol shows that this appliance used a ﬂammable refrigerant. If the refrigerant is leaked and exposed to an WARNING external ignition source, there is a risk of ﬁre. This symbol shows that the operation manual should be CAUTION read carefully.
Page 8 13. When a FLAMMABLE REFRIGERANT is used, the requirements for installation space of appliance and /or ventilation requirements are determined according to -- the mass charge amount (M) used in the appliance, -- the installation location, -- the type of ventilation of the location or of the appliance. 14.
Page 9 7. Ventilated area Ensure that the area is in the open or that it it adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
Page 10 11. Repair to intrinsically safe components • Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. • Intrinsically safe components are the only types that can be worked on while live in the presence of a ﬂammable atmosphere.
Page 11 The refrigerant charge shall be recovered into the correct recovery cylinders. For appliances containing ﬂammable refrigerants other than A2L refrigerants, the system shall be purged with oxygen-free nitrogen to render the appliance safe for ﬂammable refrigerants. This process may need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant systems.
Page 12 g)Start the recovery machine and operate in accordance with instructions. h)Do not overﬁll cylinders (no more than 80 % volume liquid charge) i) Do not exceed the maximum working pressure of the cylinder, even temporarily. j) When the cylinders have been ﬁlled correctly and the process completed, make sure that the cylinders and the equipment are removed from site promptly and all isolation valves on the equipment are closed o .
Page 13 • The hose must be of su cient length and diameter such that it will extend to at least 3 m beyond the outside of the building The venting should only take place on the certainty that the refrigerant will not get •...
Page 14 Please read thoroughly all of the instrucitons before installing or operating the unit. The following safety warnings are very important, always read and obey all safety symbols: WARNING • The unit must be earthed e ectively. • A RCD breaker must be installed adjacent to the power supply. •...
Page 15 CAUTION • The earthing pole of socket must be well grounded, make sure that power supply socket and plug are dry and connected tightly. • Before cleaning, be sure to stop the operation and turn the breaker o or pull out the power plug.

Page 18: Basic Operation Principle
BASIC OPERATION PRINCIPLE We know from experience, the natural ﬂow of heat, moves from a higher to a lower temperature source, a heat pump can transfer heat from a lower temperature source to a higher temperature source with high e ciency. The advantage of a heat pump water heater is that it can supply more heat energy, normally 3:1 times than input electricity power by extracting the heat from ambient atmosphere in a free charge way and transfer to Sanitary Hot Water.
