1WARNINGS AND SAFETY PRECAUTIONS
PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE SWITCHING ON THE COOLING UNIT AC 710!
GENERAL ELECTRICAL SAFETY GUIDELINES:
•Perform a routine check of the devices and their wiring.
•Replace worn or damaged cords immediately.
•Use appropriate electrical extension cords/power bars and do not overload them.
•Place the devices on a flat and firm surface. Keep them away from wet floors and counters.
•Avoid touching the device, socket outlet or switch if your hands are wet.
•Do not perform any alterations to the electrical part of the devices or their components.

2GENERAL DESCRIPTION
Additional Cooling Unit AC 710 is designed to regulate temperature of MC water bath in the extended range, down to 15 °C with the
resolution of ± 1 °C at standard laboratory conditions. This accessory device is also recommended for applications requiring high light
intensities as some heating of the water bath by the LEDs always occurs.
The Cooling Unit AC 710 is supplied in two versions –for 210-240 V AC and 110 V AC power line.
2.1 COOLING UNIT AC 710 EQUIPMENT
Cooling Unit AC 710 package consists of:
•AC 710 water pump (Fig. 1A)
•Hailea HC-130A water chiller
•one piece of power cable
•one piece of AUX cable
•one piece of elastic silicone tube 8/6 mm –5 m length

3INSTALLATION
Place the Cooling Unit AC 710 on a flat, firm and dry surface! Let it stand in upright position for at least 12 hours
before plugging it into power supply!
1. For a safe and proper operation of the AC 710 cooling kit, switch OFF the Multi-Cultivator MC 1000 device prior installing the Cooling
Unit AC 710.
2. Connect the water pump with the water chiller (Fig. 1A) by placing two circular rubber seals (3 mm) around the outlets on the top of
the Hailea water chiller (Fig. 1B-C). Then, put the water pump on the top of the water chiller (Fig. 1D) and place the other two seals
(2 mm) around the outlets of Hailea water chiller (Fig. 1E). Finally, fix the water pump to the water chiller with screws (Fig. 1F-G).
3. Plug the AC 710 water pump connector into the cooling pump connector (AUX 1) output on the rear panel of the MC 1000-OD (Fig.
1H). This connection provides the powering of the pump as well as controls its function in remote mode (MC 1000-OD controls the
circulation of the water in water cooling circuit).

4. Inter-connect the AC 710 water pump, Hailea water chiller and MC 1000-OD cooling spiral using the water circulation hose (Fig. 2A-
B). First, attach ca. 1 m silicone hose to the lower port (Fig. 2A-3) of the water pump. Then connect the second end of this tubing to
the top input of the cooling spiral (Fig. 2B-4).
5. After that, connect the short, ca. 30 cm long silicone hose, to the upper port (Fig. 2A-1) of the water pump and inter-connect it with
the top input of the water chiller (Fig. 2A-2).
6. Finally, use the ca. 1 m long silicone hose to connect the other output of the MC 1000-OD cooling spiral (Fig. 2B-5) with the Hailea
water chiller (Fig. 2A-6).

7. Plug the Hailea water chiller in AC electricity.
8. Switch ON the Hailea water chiller using main power button on its side. Front display shows the actual temperature in the small
water tank positioned inside of the Hailea water chiller. Please read the attached Hailea HC-130A manual for more information.
9. Switch ON the MC 1000-OD device. Fill the MC 1000-OD water bath with distilled water while the water level in water bath is sufficient
(Fig. 2C).
10. Unscrew the top cover of the AC 710 water pump reservoir and fill it with water (Fig. 2A).
11. Switch ON the cooling pump via MC front control display: Settings > Cooler > ON (Fig. 3). The active pump circulates the cold water
in the water-cooling circuit and stops automatically after 2 minutes. The cooler function is used to fill the water-cooling circuit with
water or to get rid of air bubbles in the hoses. The active water pump is indicated by a lit LED that illuminates the reservoir.

12. While the pump is active, slowly add distilled water in the water pump reservoir (Fig. 2A) to fill the entire cooling system (tubing,
Hailea inner water tank, and MC cooling spiral) –ca 1 l of distilled water is needed.
13. The minimum water level in the pump reservoir must be above its upper port. Usually, the reservoir should be filled to 2/3 of its
volume.
14. Set the required temperature of the water in the Hailea water chiller to 5-10 °C: Long push the SET button on the Hailea front panel
>> change the blinking value to the required temperature using arrows >> press SET button.
15. Set the required MC cultivation temperature using MC front control display or PBR control software. When the Multi-Cultivator is
cooling, the blue LED light indicator COOL next to the Multi-Cultivator control display is lit.
16. MC 1000-OD is now set to control automatically the temperature in the water bath by circulating the cold water from the water
chiller into the MC cooling spiral that is immersed in the MC water bath. Regulation is provided by the MC 1000-OD automatically.
Check the water level in the cooling circuit regularly. When the water level drops to 50 % of the water pump
reservoir capacity, refill the reservoir.
It is recommended not to leave the tank without the water. However, running the pump without water will not
damage the Cooling Unit AC 710. The water pump is prevented from overheating as it will automatically switch
off if the pump temperature rises too high.
