BMS. Haskris Capability • The standard Haskris chiller design is not capable of providing a connection point to the BMS. • An additional controller must be added to the chiller to provide available connection points for the physical wire connection.
Physical Connection Controller: Chillers with BMS communication capabilities have 2 controllers. • For OPC5, OPC8, OPC12, and OPC15, the controller for the BMS communication is in a separate smaller electrical enclosure, not the main electrical box. Wire connections need to be made with the controller in the smaller electrical enclosure.

9. After making all changes, power cycle the controller for the changes to take effect 10. Contact Haskris for support Baud Rate Support Note: When 3-wire RS-485 is used, baud rate is supported up to 57600.
Purpose: The chiller has a phase monitor to check incoming electrical power. Operation: The phase monitor is factory adjusted by Haskris according to the proper electrical settings for the chiller. Do not adjust the knobs on the phase monitor without discussion and approval from Haskris.
Operation: Rotate the switch to make the chiller run when in the ON position (horizontal) or stop when in the OFF position (vertical). If a fault occurs, turning the switch to OFF and then back ON will reset the fault. ON/OFF switch, vertical position Phone: 001 847 956 6420 Page 37 of 55 Email: service@haskris.com...
Pump Priming Purpose: All fluid is removed from the pump head prior to shipment from Haskris. When starting the pump, it needs to be filled with fluid. This process is called priming the pump. When the reservoir is full, the pump suction line is “flooded”. In some cases, this flooded suction will automatically prime the pump.
1. Chillers that include a model CM5-4 pump have an internal ball valve for this purpose. • On the OPC5, OPC8, OPC12, and OPC15, the ball valve is located on a length of hose between the evaporator outlet and the tank.
Purpose: The pump motors must rotate the correct direction to provide proper pressure and flow. Haskris confirms proper rotation direction prior to shipment. The phase monitor is configured to be the primary check on rotation direction. Typically, no other verification is necessary for the pump rotation direction.

XII. Chiller Features Cellular Communication and Remote Monitoring Purpose: The chiller uses a cellular connection to enable Haskris to remotely view the controller 24/7/365 for diagnostics and addressing issues. Haskris can receive alerts if there are faults. Method: The chiller has a cellular modem and 2 antennas to communicate with the cell towers.
Additional Sensors Purpose: The chiller has additional pressure and temperature sensors that are used for improved real-time diagnostics. Phone: 001 847 956 6420 Page 51 of 55 Email: service@haskris.com...
Operation: When the chiller is in eco mode, the status on the display will say “ON eco”. The controller initiates eco mode based on the operation of the refrigeration hot gas bypass valves and the refrigerant head pressure. Eco mode active Phone: 001 847 956 6420 Page 52 of 55 Email: service@haskris.com...
This will not reduce the long-term performance or reliability of the chiller. During normal operation, the chiller responds to changes in heat load from moment to moment and supply stable supply fluid temperature to the MRI. Phone: 001 847 956 6420 Page 53 of 55 Email: service@haskris.com...
Schedule: Inspections should happen at least once every 12 months. If the chiller is not being monitored remotely by Haskris, inspection every 6 months is recommended. Activity: During each inspection, preventative maintenance should be performed. Use the Haskris provided Preventative Maintenance checklist.
Compare values to the chiller or component name plate. Chillers include a phase monitor. Refer to the fault indicators provided on the phase monitor and contact a licensed electrician to correct any faults. Phone: 001 847 956 6420 Page 55 of 55 Email: service@haskris.com...
