Page 6 Warning Installation Meaning The heat pump must be installed by qualified personals, to avoid improper installation which may lead to water leakage, Professional installer electrical shock or fire. is required. Please make sure that the unit and power connection have good earthing, otherwise may cause electrical shock.
Page 7 ATTENTION Meaning Installation The unit CANNOT be installed near the flammable gas. Once there is any leakage of the gas, fire may occur. Installation Place Make sure that the basement of the heat pump is strong enough, to avoid any decline or fall down of the unit Fix the unit.
Page 8 Usage Meaning The earth electrode of socket should have the perfect earth wiring and the rating current should be more than 16A. Keep the socket and plug dry to avoid leakage and check if they are connected well usually. The check ways are as follow: Put the plug into the socket and turn on the unit, then pull out the plug half an hour later and check if the plug is hot.

Page 13 If any hot work is to be conducted on the refrigeration equipment or any associated parts appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area 6) No ignition sources No person carrying out work in relation to a refrigeration system which involves exposing any pipe work that contains or has contained flammable refrigerant shall use any sources of ignition in such a...
Page 14 Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used.
Page 15 shall be at the correct rating. Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the atmosphere from a leak Cabling Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration.
Page 16 Purge again with inert gas; Open the circuit by cutting or brazing. The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be "flushed" with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally...
Page 17 refrigerant cylinders: All personal protective equipment is available and being used correctly; The recovery process is supervised at all times by a competent person; Recovery equipment and cylinders conform to the appropriate standards. d) Pump down refrigerant system, if possible e) If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system f) Make sure that cylinder is situated on the scales before recovery takes...
Page 18 condition. Before using the recovery machine, check that it is in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt. The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant Waste Transfer Note arranged.

Page 33: Failure List & Troubleshooting
Failure List & Troubleshooting 7.1. Non-error tips 1 Why the compressor is not running when I start up the unit? Answer: When the unit is powered on after the last shut-down, the compressor will not run until 3 minutes later. This is the self-protection of the unit. 2 Why sometimes the outlet water temperature on the display increases slowly? Answer Because the water temperature is different between the upper layer and bottom layer in the tank at the beginning.
