WARNING :
Installing recirculation pump
When Hydro Kit is used with the sanitary water tank, it is STRONGLY recommended to install
recirculation pump to prevent cold water at the end of hot water supply flooding out and to
stabilize the water temperature inside the sanitary water tank.
- The recirculation pump should be operated when sanitary water demand is not required.
Therefore, external time scheduler to determine when the recirculation pump should turn on
and turn off is required.
- The operating duration time of the recirculation pump is calculated as follow :
Duration time [minute] = k * V / R
k : 1.2 ~ 1.5 is recommended.
(If distance between pump and tank is far, then choose high number.)
V : Volume of sanitary water tank [liter]
R : Water flow rate of pump [liter per minute], which is determined by pump performance
curve.
- The pump operating start time should be prior to the sanitary water demand.

Final Check
• Flow direction :
- Water should flow from water outlet of the unit to sanitary tank water inlet when sanitary tank
heating is selected.
- To verify the flow direction, check temperature at the water outlet of the unit and water inlet of
sanitary water tank.
- If correctly wired, these temperatures should be almost equivalent if thermal insulation of water
pipe is well performed.
• Noise or water pipe vibration while 3way valve operation
- Due to surging effect or cavitation effect, noise or water pipe vibration can be occurred while
3way valve is operating.
- In that case, check followings :
• Is water circuit (both under floor water loop and sanitary water tank loop) fully charged? If not,
additional water charging is required.
• Fast valve operation yields noise and vibration. Appropriated valve operating time is 60~90 seconds.

system stopping.
- If system found some problem, which is not critical to system operating for yielding heating
energy, the system can temporarily continue in emergency mode operation with end user's decision.
• Classified Trouble
- Trouble is classified two levels according to the seriousness of the problem : Slight Trouble and
Heavy trouble
- Slight Trouble : Sensor trouble.
- Heavy trouble : Compressor cycle trouble.
- Option Trouble : a problem is found for option operation such as water tank heating. In this
trouble, the troubled option is assumed as if it is not installed at the system.
• Emergency operation level
- When the system is faced with trouble, it stops and waits for user’s decision. : Calling service
center or starting emergency operation.
- To start emergency operation, user simply push ON / OFF button once more.
- Two different levels are prepared for emergency operation : High temperature cycle and low
temperature cycle.
- In emergency operation mode, user can not adjust target temperature.

• Duplicated trouble : Option trouble with Slight or Heavy trouble
If option trouble is occurred with slight (or heavy) trouble at the same time, the system puts higher
priority to slight (or heavy) trouble and operates as if slight (or heavy) trouble is occurred.
Therefore, sometimes sanitary water heating can be impossible in emergency operation mode.
When sanitary water is not warming up while emergency operation, please check whether the sanitary water sensor and related wiring are connected well or not.
• Emergency operation is not automatically restarted after main electricity power is reset.
In normal condition, the unit operating information is restored and automatically restarted after main
