Page 5: Technical Requirements
II. Technical Requirements Note: Features and customizations may impact the technical requirements. Contact Haskris for details about a specific unit or design. Phone: 001 847 956 6420 Email: service@haskris.com Page 5 of 31... -
Page 6: Clearances
Maintain at least 36 inches (91 cm) on the front for access to the main controller during normal operation. o Additional clearances on the sides and rear may be required for service. Phone: 001 847 956 6420 Email: service@haskris.com Page 6 of 31... -
Page 7: Location
• For units with air-cooled condensers, confirm ambient air temperature is compatible. Confirm the climate control system has enough spare capacity to accept heat rejection from the chiller. Refer to the table below. Haskris Chiller Standard Ambient Maximum Heat Model... - Page 8 Confirm the minimum available differential pressure is 25 psi (1.7 bar) o Confirm the maximum differential pressure is 50 psi (3.4 bar) Water-cooled Condenser: Required facility water flow rate Phone: 001 847 956 6420 Email: service@haskris.com Page 8 of 31...

Page 9: Installation
III. Installation Line Sizing Contact Haskris for help: Haskris is available to review pipe runs, pressure drop, etc. and make recommendations for individual sites. Approach to line sizing • Size all interconnecting hose and piping equal to or larger than the connections on the chiller. - Page 10 • If the total straight pipe length is less than 200 ft (61.0 m) use 2” nominal pipe size (ID). • If the total straight pipe length is less than 510 ft (155.4 m) use 2-1/2” nominal pipe size (ID). Phone: 001 847 956 6420 Email: service@haskris.com Page 10 of 31...

Page 11: Piping
• For water-cooled units, it is recommended to install an 80-mesh wye strainer at the building water inlet. This will provide some protection for the chiller’s condenser if the facility water has particulate contaminants. Phone: 001 847 956 6420 Email: service@haskris.com Page 11 of 31... -
Page 12: Electrical
Energizing the service: Electrical power must be applied to the chiller at least 12 hours in advance of startup. This energizes the crankcase heater and drives out any accumulated liquid refrigerant in the compressor. Phone: 001 847 956 6420 Email: service@haskris.com Page 12 of 31... -
Page 13: Filling The Reservoir
• Make sure additional water is on hand when the unit is started up to top off the liquid level as the external piping is filled. • Note: Some units are designed for compatibility with other fluids. Contact Haskris if you are unsure what fluids are compatible with your unit. -
Page 14: Startup
If unable to energize for the full 12 hours, energize for a minimum of 1 hour, switch the unit ON and wait until the compressor starts. Cycle the unit OFF and ON 3 to 4 times before leaving the unit switched ON. Phone: 001 847 956 6420 Email: service@haskris.com Page 14 of 31... -
Page 15: 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 most cases, this flooded suction will automatically prime the pump. -

Page 17: Pump Supply Pressure
Note: When partially closing a ball valve from a fully open position, it is normal to see no change in operating pressure until the handle is adjusted a significant amount. Contact Haskris for help: Haskris is available to review pressure adjustments. Final Checks •... -
Page 18: Controller Display Controller Types
V. Controller Display Controller Types The chiller will have one of three different types of controller. Use the table below to identify the relevant controller type. Phone: 001 847 956 6420 Email: service@haskris.com Page 18 of 31... -
Page 19: On/Off Cycling Control
Purpose: The controller maintains temperature by cycling refrigeration ON/OFF using a set point and a differential. Supply fluid will oscillate between the set point and +4°F (+2.2°C) above the set point. Operation: Follow instructions below to adjust the temperature set point Phone: 001 847 956 6420 Email: service@haskris.com Page 19 of 31... -

Page 26: Remote Communication Capability
• Remote ON/OFF interlock • Modbus capability • BACnet capability Contact Haskris for help: Haskris is available to provide detailed information about a specific design’s capabilities. Modbus and BACnet Purpose: Some facilities have centralized building monitoring systems (BMS). This requires a physical wire connection point between the chiller and the BMS as well as appropriate software in the chiller. - Page 27 5. Press the buttons to highlight Communication 6.

Page 29: Maintenance
Replacement strainers are available from Haskris. Notes: A dirty strainer can cause cavitation which can damage the pump. Failure due to cavitation is not covered under the warranty. -
Page 30: Particle Filter
Maintenance: Record the pump’s running fluid pressure at the completion of startup when the filter is clean. Replace the filter when the pressure increases 5psi to 6 psi (0.3bar to 0.4 bar) above the startup running pressure. Replacement filters are available from Haskris. Wye Strainer Purpose: Some units have water-cooled condensers. -
Page 31: Liquid Level And Water Quality
Glycol: If biological growth persists even after regularly changing the water and flushing the system, use laboratory/food grade (99% pure) propylene glycol to create a 10% mixture. Haskris recommends that additives be used only as a means of last resort.
