Mono bloc Unit
In case of a power supply failure or pump operating failure, drain the system (as suggested in the figure below).
H<H
When water is idle inside the system, freezing up is very likely to happen which could
damage the system.
• Do not obstruct the air inlet and air outlet vents, it may cause low performance or
breakdown. Please remove obstacles to assure the ventilation.
• During winter, please clean and remove the snow near mono bloc unit so that the snow
does not cover the air inlet and air outlet vents.
External filter
• Clean the external filter at least once a year. Failure to do so may cause the filter to clog up, which may lead to system
breakdown. Consult an authorised dealer.
Inspection
• In order to ensure optimal performance of the units,
seasonal inspections on the units, external filter and field
wiring have to be carried out at regular intervals. Consult
an authorised dealer about maintenance.
• Clear any obstruction on the air inlet and outlet vents of
the mono bloc unit.
For extended non-use
• Do not switch off the power supply. Switching off the
power supply will stop the automatic water pump
operation and will cause jamming in the water pump.
Non serviceable criteria
Disconnect the power supply
then please consult an authorised dealer under the
following conditions:
• Abnormal noise during operation.
• Water/foreign particles have entered the remote control.
• Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.
Maintenance
Weekly timer setting
■Note:
• You may set the timer for each day of the week (Monday to Sunday) with 6 programmes per day.
• When the system is switched on by the timer, it will use the previously set temperature to control the water outlet
temperature.
• The same timer programme cannot be set on the same day.
• You may also select 2 or more days with the same timer setting.

The following symptoms do not indicate malfunction.
Symptom Cause
Water flowing sound during operation. • Refrigerant flow inside the unit.
Operation is delayed a few minutes
after restarting.
• The delay is a protection for the compressor.
Mono bloc unit emits water/steam. • Condensation or evaporation occurring in the pipes.
Steam comes out of the mono bloc
unit in the heating mode.
• It is caused by defrost operation in the heat exchanger.
Mono bloc unit does not operate. • It is caused by the protection control of the system when outdoor temperature is
out of the operating range.
System operation switches off. • It is caused by the protection control of the system. When the water inlet
temperature is lower than 10 °C, the compressor stops and the backup heater
power turns on.
System is hard to heat up. • When the panel and the floor are heated simultaneously, warm water temperature
may decrease, which may reduce the heating ability of the system.
• When the outdoor air temperature is low, the system may need longer time to heat
up.
• Discharge outlet or intake inlet in the mono bloc unit is blocked by some obstacle,
such as a pile of snow.
• When the preset water outlet temperature is low, the system may need longer time
to heat up.
System does not heat up instantly. • System will take some time to heat up the water if it starts to operate at cold water
temperature.
Backup heater is automatically turned
ON when it is disabled.
• It is caused by the protection control of the unit heat exchanger.
Operation starts automatically when the
timer is not set.
• Sterilisation timer has been set.
Display power consumption remains
as previous value.
• Memory is saved on hourly basis. If a power failure occurs, the data kept from last
hour will be displayed.
• Total power consumption has reached 999 days. Press to reset the counter.
HEAT indicator blinks on the display. • System is performing deice operation.
Loud refrigerant noise continue for a
few minutes.
• It is caused by protection control during deice operation at outdoor ambient
temperature lower than -10°C.
