DANGER
The operation of the thermal cut-out indicates a possibly dangerous situation. Do not reset the thermal cut-out until the water heater has been serviced by a qualified person.
Failure to operate the relief valve easing gear at least once every six months may result in the water heater exploding. Continuous leakage of water from the valve may indicate a problem with the water heater.
If the hot water system is not used for two weeks or more, a quantity of highly flammable hydrogen gas may accumulate in the water heater. To dissipate this gas safely, it is recommended that a hot tap be turned on for several minutes or until discharge of gas ceases. Use a sink, basin, or bath outlet, but not a dishwasher, clothes washer, or other appliance. During this procedure, there must be no smoking, open flame, or any electrical appliance operating nearby. If hydrogen is discharged through the tap, it will probably make an unusual sound as with air escaping.
Before touching electric terminal parts, turn off power switch.
Do not touch the inner parts of the controller. Do not remove the front panel. Some parts inside are dangerous to touch, otherwise a machine malfunction may be caused.
When front panels are removed, live parts can be easily touched by accident.
Never leave the unit unattended during installation or servicing when the front panel is removed.
Do not touch water pipes during and immediately after operation as the pipes may be hot and could burn your hands. To avoid injury, give the piping time to return to normal temperature or be sure to wear protective gloves.
Do not touch any switch with wet fingers. Touching a switch with wet fingers can cause electrical shock.
Before touching electrical parts, turn off all applicable power to the unit.

WARNING

If the water supply pressure exceeds the rated pressure, a pressure reducing valve is to be fitted in the installation.

NOTE
Do not let air, dust, or other impurities fall in the pipe system during installation. The connecting pipe should not be installed until the indoor and outdoor units have been fixed already. Keep the connecting pipe dry, and do not let moisture in during installation. When connecting copper pipe, please wrap it with thermal insulation material.
4.4 Vacuum Drying
4.4.1 Purpose Vacuum drying should be performed in order to remove moisture and non-condensable gases from the system. Removing moisture prevents ice formation and oxidization of copper piping or other internal components. The presence of ice particles in the system would cause abnormal operation, whilst particles of oxidized copper can cause compressor damage. The presence of non- condensable gases in the system would lead to pressure fluctuations and poor heat exchange performance. 4.4.2 Procedure

Notice

Table 4-5

Before performing vacuum drying, make sure that all the outdoor unit stop valves are firmly closed.
1. Mixing of pump lubricant with compressor oil could cause compressor malfunction and a one-way valve should therefore be used to prevent vacuum pump lubricant seeping into the piping system. 2. Using a vacuum pump with a discharge in excess of 4L/s and a precision level of 0.02mmHg is recommended.

After vacuum drying, keep the hoses

connected to the pressure gauge and to

the outdoor unit stop valves, in preparation

for refrigerant charging.

4.5 Refrigerant charge
Pipe length is 2~20m. If the pipe length is less than 10m, there is no need to add additional refrigerant charge. If the pipe length is more than 10m, adding additional refrigerant charge is necessary, and the rule is 20g/m for the additional pipe.
