3.1 Reception and Inspection
On receipt of the ultracool unit, it must be inspected for damage during transport. In the case of any damage, external or internal, this cannot be referred to the manufacturer because all units are checked before dispatch. If any damage is observed, this should be documented and reported to the forwarding company. The ultrafilter warranty does not include any damages incurred during transportation.
The refrigerant circuit controls are set before shipment of the unit. They should not be re-adjusted under any circumstances (except by our ultrafilter service department). This would void the warranty of the unit.
3.2 Transportation
Keep the unit upright at all times. Do not tilt when shipping or moving. The tilting of the ultracool unit may affect the internal suspension of the refrigerant compressor.
The ultracool unit must be transported by palet jack or forklift truck.
3.3 Site
We recommend the installation of the ultracool unit in a well-ventilated site and in a corrosive-free, dust-free atmosphere. The air renewal of the room should be at least ¾ of chiller’s motor fan flow (see point 8.1). The electrical protection degree of the ultracool unit is IP54 (except models UC-10 to UC-40, which have an IP44 protection degree). In the case of out-door installation (only from UC-60 up to UC-240) the chiller must be protected from rain with a roof and it must be installed in such way that the control panel receives as few direct sunlight as possible. The inlet of fresh air onto the condenser should be in the most direct way possible, avoiding any chance of air recycling .

3.4 Identification Labels on the ultracool unit
You can find the following labels stuck on the ultracool unit.
3.5 Water Connection
Superplus models: It is mandatory to install a manual valve to adjust the pressure drop in the user system in accordance with the nominal pump pressure (See point 8.1). Standard models: The user pump must provide the chiller with the flow indicated in the ultracool characteristics plate (See point 8.1). Take into account that the maximum pressure at the chiller’s inlet cannot exceed 6 bar. It is necessary to install a water filter at the inlet of the chiller in order to avoid free particles in the water, which could block the evaporator plates or damage the pump. ultrafilter will not accept any warranty for the evaporator damage or performance loss if there is no water filter. An appropriate filter is the ultrafilter P-KG with a PPTF or similar with a filter element of 100 microns or less.

3 Installation
The water connection of the installation of the ultracool unit should be carried out according to the indications of the labels (stickers) present on the unit. In the UC-10 to UC-40 units the tank has to be filled directly by removing the chiller and tank covers. The diameter of the inlet and outlet lines must be same size or larger than those corresponding to the water inlet and outlet of the ultracool unit. Always install thermal insulation for all pipes. In the installations in which the water level of the circuit exceeds the maximum level of the tank inside the ultracool unit, it will be necessary to install a non-return valve in the water outlet of the ultracool unit and a solenoid valve in the water inlet. Terminals at 230 VAC are designed for that purpose, except for the UC-10, to carry out the supply of this solenoid valve. (see electrical diagrams).
3.6 Electrical Connection
The electrical design of the ultracool complies with EN-60204 norms. It must be checked that the supply voltage does not exceed a maximum variation of 10% referring to nominal. For the electrical supply of the ultracool unit, use an appropriate electrical line according to the data in the characteristics plate. (See also point 8.1) A system of fuses or circuit breakers must be installed before the power inlet connection to the ultracool unit. The maximum size of these protections is defined in the ultracool characteristics plate. In the three phases models there are two prepared terminals to connect a remote on-off switch away from the unit. These terminals are at 230V.

4 Start-Up
4.3 Chiller start-up
When the ultracool unit is started for the first time, it is necessary to turn ON the Main power switch (element 1 in the control panel, see point 5) and wait six hours before continuing with the start-up sequence. This time is necessary for the crankcase of the compressor to heat it up in the models that have it (UC-60 to UC-240). The oil in the crankcase of the compressor remains warm whenever the main power switch is in the ON position and the unit is connected to the line voltage. For this reason stop the ultracool unit by using the off-switch, leaving the Main power switch in the ON position. Fill the tank with water of the required quality (see annex 10) or with refrifluid through the provided connection until the maximum level of the tank is reached. Start the ultracool unit with the On/Off switch (element 2 in the control panel, see point 5). Stop the ultracool unit and refill the tank to the correct water level. Repeat this procedure until the water level in the tank remains constant. In the three phase units, from UC-60 to UC-240, of the superplus version it is necessary to verify the direction of rotation of the pump at the initial start up. To do so, start and stop the ultracool unit, using the On/Off switch (it is easier to see the turn direction when the pump is stopping). In the case of the pump rotating in the opposite direction from the indicated, it will be necessary to exchange two phases in the main power supply. It will not be necessary to check the turn direction of the fans, because they are delivered in phase with the pump. Since it may be difficult to see the pump’s rotation direction, verify that you did this operation correctly when the motor fan starts working: The air should enter the condenser and go out through the top of the chiller. If the air is moving in the opposite direction then exchange two phases in the main power supply. In the standard models, it will be necessary to check the direction of rotation of the fans, to do so, follow the procedure described in the last paragraph. Connect the On/Off switch so that the ultracool unit starts. At the same time the digital thermometer and all the indicators that should light up will turn on too, according to their function. Adjust the water pressure, using the external valve at the ultracool outlet, to the value indicated on the carachteristics plate (Nominal pressure).

5 Control Panel
5.1 Components of the Control Panel
The control panel consists of the following elements: 1. Main power switch: connects and disconnects the ultracool unit
from the power supply. Not available in models UC-10 to UC-40.
2. On-Off switch: starts up the different elements that make up the ultracool unit.
3. Water gauge: indicates the working pressure of the pump. While the
chiller is working its value must be adjusted to the nominal pressure indicated on the characteristics plate (Pnom). (See section 4.3)
4. Control thermostat: indicates the cold water temperature at the
outlet of the ultracool unit and enables it to be regulated.
5. Pump indicator (superplus version): this remains lit when the pump is working.
6. Compressor indicator: this remains lit when the compressor is
working. Not available for models UC-10 to UC-40.
7. Compressor alarm indicator: lights up when the compressor stops due to over-intensity. Not available for models UC-10 to UC-40.
8. Water level alarm indicator (superplus version): this is lit when the
water level in the tank is too low. It causes the ultracool unit to stop.
9. Low flow/temperature control indicator: This flow control can stop the compressor when there is no water circulation through the external water circuit. In this case some flow still circulates inside the chiller. The temperature control can also stop the compressor when you try to reach water temperatures below 7ºC (45ºF). To be able to reach temperatures below that contact an authorised technical service.
10. Low refrigerant pressure alarm indicator: this is lit when the
pressure of the refrigerating circuit (see element 13 ) is below the minimum allowed (0.5 bar). It causes the refrigerant compressor to stop.
11. High refrigerant pressure alarm indicator: this is lit when the
pressure of the refrigerating circuit (see element 12 ) is higher than the maximum allowed (20 bar). It causes the refrigerant compressor to stop.
12. High pressure gauge: indicates the pressure at the high pressure
side of the refrigerating circuit (after de compressor). Only in the models from UC-100 to UC-240.

5.2 Control Thermostat
5.2.1 Operation
During normal operating conditions, the display of the control thermostat shows the cold water outlet temperature measured by the probe.
In the case of alarm, the display flashes the activated alarm code alternately with the probe temperature.
Setting the temperature: to introduce the required working temperature (between –5 and 25) the following procedure should be followed:
- Hold down for 2 seconds the button set and the current set temperature will start flashing.
- To increase or to decrease the value of the setpoint, use the UP and DOWN buttons.
- Press set again to confirm the new value.

6 Maintenance 6.1 Basic Maintenance
Weekly: Verify that the water temperature indicated on the control thermostat is approximately at the setpoint. Verify that the pressure of the pump is the same as the nominal pressure (Pnom) indicated in the characteristics plate. Verify the water level in the tank. Verify the state of the water filter, if the pressure drop exceeds 0.5 bar (8 psi) change the filter element. Monthly: With the unit disconnected (Main power switch Off), clean the condenser with a blast of compressed air, from the inside towards the outside. Clean the housing, internally and externally, eliminating the dust present especially on the water pump rack. Yearly: Change the filter element and refill the water circuit with clean water or refrifluid.

10 Annexes
10 Annexes 10.1 Water quality
In order to protect the water circuit of the ultracool units, the water to be cooled must have specific physical/chemical properties so that it is not aggressive. If this water is outside any of the limits listed in the table below, it can seriously damage some of the materials of the ultracool unit.
Parameter Limit values pH 7 – 8
Total Hardness (TH) < 150 ppm Conductivity 50 – 500 µS/cm
NH3 < 2 ppm Total iron ions (Fe2+ and Fe3+) < 0.2 ppm
Chloride (Cl-) < 300 ppm H2S < 0.05 ppm
Solid particles < 150 µm Ethylene glycol (only units
from UC-60 to UC-240) 30%
The Total Hardness is specified in ppm (mg/L) of Ca2CO3. Please note that ultra pure waters like deionised water can also be harmful for some of the materials of the ultracool units as they have a conductivity below 50 µS/cm. The product refrifluid supplied by ultrafilter includes in its composition an anticorrosive, bactericide and antifreeze (until –7ºC / 19.4 ºF). It has the following characteristics:
Parameter Limit values pH 7.5
Total Hardness (TH) < 30 ppm Conductivity 50 µS/cm
NH3 0 ppm Total iron ions (Fe2+ and Fe3+) < 0.2 ppm
Chloride (Cl-) < 1 ppm H2S 0 ppm
Solid particles < 50 µm Ultrafilter will not accept any warranty for any damage caused by water that is out of one or more of the above limits. Therefore, if there is not a total security on the water quality we advise the use of our product refrifluid. This fluid has been specially designed for the protection of closed water circuits. Besides this ultrafilter offers the possibility of doing a basic analysis of a water sample supplied by the customer.
