LAUDA Ultracool S.L. personnel, or personnel authorized by LAUDA Ultracool S.L., should carry out any work in the refrigerating or electric circuit during the warranty period. After the warranty period, the work must be carried out by qualified personnel.

INTRODUCTION 1.1 GENERAL NOTES • This water chiller complies fully with CE. • The Company does not accept responsibility if safety regulations are not met during handling, operation, maintenance and repair, even though these may not be strictly stated in this operation manual. •...
If any damage is observed, this should be documented and reported to the forwarding company. The LAUDA Ultracool S.L. 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 an authorized service agent).
The inlet of fresh air onto the condenser should be in the most direct way possible, avoiding any chance of air for UC 8 to 24 models and 2m (80") for recycling (the ceiling above should not be at less than 1m (40") the UC 50 and 65 models In case of installation in a small room it is imperative that the room has an appropriate ventilation system to evacuate all the heat generated by the chiller as explained before on this same point.
When possible, install the water lines at the same level as the chiller until reaching the application The height difference between the chiller and the application should never exceed 10m (33 feet). 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 check valve in the water outlet of the Ultracool unit and a solenoid valve in the water inlet.

Note: The external controller display has no IP protection; make sure it is installed on a location protected from the weather, from dust and from any water splashes. If the chiller is controlled remotely, it is also possible to remove the display after the initial configuration and store it in a safe location, as the chiller does not need it to operate.
STARTUP 3.1 OPERATING CONDITIONS Water temperature at the inlet: Nominal: 15ºC (59ºF) Maximum: 40ºC (104ºF) (1) Cold water temperature at the outlet: Nominal: 10ºC (50ºF) Minimum: 7ºC (45ºF) (2) Maximum: 35ºC (95ºF) Temperature of the ambient air: Nominal: 25ºC (77ºF) Minimum: -15ºC (5ºF) (3) Maximum:...
Only an authorized technical service can adjust the antifreeze set point. The following table shows the ethylene glycol concentration and the antifreeze adjustment required: Min Ambient Temperature Glycol concentration (4) and Less than 0ºC until - Less than -5ºC until antifreeze adjustment 0ºC or more 5ºC...

(see annex 9.1), the suitable glycol concentration and the Refrifluid B additive according to point 3.1 of this manual. Fill it directly to the tank until the maximum level of the tank is reached. On UC 50 and UC 65 models, lift the level switch manually to make sure it resets itself: when it resets you will hear its contact “click”.

Increase the cold water setpoint up to the maximum allowed value (see point 3.1) to prevent the compressor from starting. Switch the main power switch OFF and then back ON. Open the right panel and adjust the water outlet valve so that the pump works at the nominal pressure indicated in the chiller’s data plate.
CHILLER CONTROLS 4.1 CONTROL AND MONITORING ELEMENTS Main Power Switch Status LED Warning/Alarm LED External controller display Webserver controller display The following elements allow controlling the chiller and monitoring its status: 1. Status LED: It blinks when the unit is turned Off and is waiting for an On signal. It is lit steadily when the unit is turned On.
4.2 UC CONTROLLER Controller buttons: Alarm button: Displays the list of active alarms. It's also used to manually reset alarms Prg button: Used to access the configuration menu (for authorized service only) Esc button: Return to the main screen Up – Down buttons: Navigate between the display screens or increase/decrease the value of a selected parameter Enter button: Used to enter a subscreen/menu from the main screen or to switch between screen navigation and the different parameters that can be modified on a particular screen...
On/Off from the display: As long as the remote On/Off is connected, the chiller can be turned On and Off from the display (either the remote display connected to the chiller or the webserver on a connected computer). In order to start/stop the chiller from the display, go to the On/Off screen (see point 4.2), and use the Up/Down buttons to toggle between On and Off.
Please note that the heat generated by the pump is limited and, depending on the thermal losses in the whole water circuit, it’s possible that the temperature cannot reach the preheating setpoint even with the pump running all the time. It is strongly recommended that all water pipes are properly insulated to minimize the thermal losses.

2. Use the Down button to select "SETTINGS" and press Enter to access the Settings menu: 3. Use the Down button to select "TCP/IPv4 SETTINGS" and press Enter to access the IP Configuration screen: 4. In this screen, use the Enter button to move to the next field and Up and Down to change the values.
MAINTENANCE 5.1 BASIC MAINTENANCE Weekly: Verify that the water temperature indicated on the controller display is approximately at the setpoint. Verify the water level in the tank. Verify the pressure drop of the water filter (on the "Info – Process circuit" screen of the Information screens loop, see point 4.3).
TROUBLESHOOTING 6.1 SAVING A LOG FILE IN CASE OF ALARM The chiller has a built in a log function that continually records data from the last 36 hours of operation (older data is automatically overwritten). If an alarm triggers and it’s not possible to restore the chiller by following the indications on this chapter, then follow these steps to save a copy of the stored logs shortly after the alarm has triggered.

Do not use automotive antifreeze. Use lab grade ethylene glycol only! Do not use an ethylene glycol concentration above 40%; this would damage the water pump. LAUDA Ultracool S.L. will not accept any warranty for any damage caused by water that is out of one or more of the above limits.
