Page 11: Installation: Electrical, Connection To Outdoor Chiller
• Do not mount or support any electrical service disconnect directly to the heat exchanger. Electrical connection: Use a dedicated service disconnect and time delay fusing. Connect incoming electrical to the distribution block in the electrical box. Distribution Block Phone: 001 847 956 6420 Page 11 of 26 Email: service@haskris.com... -
Page 12: Connection To Outdoor Chiller
Connection to Outdoor Chiller Purpose: Some heat exchanger systems come with a Haskris outdoor chiller. For these systems, the heat exchanger must be wired to the chiller to ensure that Haskris will get remote notifications of heat exchanger faults. Installation: A 150ft (45.7m) cable is provided for this connection. Connect the provided cable to the orange terminal strip in the chiller’s electrical box. -
Page 13: Installation: Filling The Reservoir
• Replace cap after filling. • Make sure additional drinking/spring water is on hand to top off the tank during startup when the unit’s pump fills the external piping. Phone: 001 847 956 6420 Page 13 of 26 Email: service@haskris.com... -
Page 14: Installation: Final Checks
Controller Faults Check: Press the button on the controller. The screen should say NO ALARMS. If any faults are described, consult Haskris to resolve these. Phone: 001 847 956 6420 Page 14 of 26 Email:... -
Page 15: Pre-Startup Checklist
L1-L3 Communication: ❑ Communication wiring between the WW and OPC is installed (if Haskris chiller was provided). Fluid fill: ❑ The tank is full of drinking/spring water. The tank should be filled to about 3” from the top of the tank, just below the overflow. -
Page 16: Optional Modbus Or Bacnet Communication Capability
BMS using Modbus or BACnet communication. Operation: The method of interfacing with the BMS varies depending on the specific design and whether the heat exchanger is paired with a Haskris outdoor chiller. Contact Haskris for details. Phone: 001 847 956 6420... -
Page 17: Startup
Purpose: The heat exchanger 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 heat exchanger. Do not adjust the knobs on the phase monitor without discussion and approval from Haskris. -

OFF position (vertical). If a fault occurs, turning the switch to OFF and then back ON will reset the fault. Note that city water backup is active while switch is in the OFF position. ON/OFF switch, vertical position Phone: 001 847 956 6420 Page 18 of 26 Email: service@haskris.com... -
Page 19: Pump Priming
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. -
