Operational Control
Intelligent temperature controller with more perfect control system,
control the time delay of compressor, fan and on/off, defrosting
temperature into the Settings, defrosting quit. the temperature of the
cooling and heating operation process by time and temperature of double
protection self-checking overheat detection, sensor self-inspection (E1
said sensor fault line), the operation is simple, powerful.
After the machine power on, open the switch, panel auto-matically detect
probe the relationship between temperature and set temperature, etermine
the machine cooling or heating mode (the machine is only cooling, and
standby mode).
When the water temperature is greater than the set temper-ature more
than 2 °C/°F, the machine start delay cooling mode operation after three
minutes. When the water temperature is less than the set temperature
below 2 °C/°F, the machine start delay heating mode operation after three
minutes. When the water temperature and set temperature within 2 °C/°F,
standby the machine.
Temperature once set, the parameters are stored, if not reset, the machine
has been operating and stop to set temperature.
The chiller has power failure memory function. Call again after the
blackout, still in accordance with the mode of the original machine.
The chiller has the compressor delay start protection function. Stop after
restarting, if the downtime is less than 3 minutes, automatic control system
delay to meet 3 minutes after the restart.
See illustration on the control panel 1~2.
Press and hold the SET into the function of temperature setting,
adjusted by “▲”key or “▼”key until conform to the requirements of the
owner.
Stop the operation (don't press any keys) for 10 seconds, automatically
converted to digital tube display temperature, set up effective.

1. In order to ensure safety, please place the machine in aquatic animals or other liquid
does not splash into place, in order to avoid leakage of dangerous.
2. Please place the machine where the children not easy contact, lest the children play and
accidental damage.
3. The operation of the machine need ventilation cooling. Machines placed must keep
enough space, therefore, generally The direction of the wind at no less than 30 cm and The
direction of the exhaust air of not less than 50 cm.
4. In order to prevent the machine from the water circulation pipeline jam, please on the
inlet side of the machine assembly filtering device or series filter barrels outside the
cylinder.
5. Please use hard hose or tube wall thickness, not easy to winding soft hose as machines
in and out of the water pipe, In order to prevent the water pipe is blocked and the
refrigerating capacity of the machine impact or not refrigeration.
6. Please check whether the power supply voltage before starting the conform to the
requirements of the machine parameters, Open the water cycle system, and make sure the
normal operation of water flow.
7. Please regular cleaning machine(Generally should not be more than a month),Ensure
machine ventilation cooling, prevent the dust adhesion caused by leakage phenomenon.
8. If you don't use machine for a long time, please empty your machine internal moisture,
and clean, Placed in ventilated dry place, make sure the next can normal use.

1. Machine normal use for a long time, If it is found that the capacity
significantly less or without refrigeration, should consider whether or not
the refrigerant quantity is not enough, Please sent to professional
maintenance and repair, and infuse the right amount of the same
refrigerant(R22 or R410a).
2.Use for a long time, if the air temperature or water temperature is too high,
poor ventilation dust accumulation make machines could cause compressor
protective stop working, At this time should be cut off power supply, clean
machine and strengthen the ventilation and heat dissipation, which can be
restored to normal work.
