Page 3: Installation
3’ (91cm) clearance on the front is required. Mounting • A CWS must be mounted on a wall. Use appropriate anchors to support the weight of the unit. • A CGS must be mounted on the floor and secured to a wall. Use appropriate anchors to prevent any risk of tipping over. -
Page 4: Startup
Purpose: Units configured for 3-phase electrical have 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 unit. Do not adjust the knobs on the phase monitor without discussion and approval from Haskris. -
Page 5: On/Off Switch
ON/OFF Switch Location: A rotary ON/OFF switch is located on the front or side of the unit (Figure 3). Operation: Rotate the switch to turn the unit ON or OFF. If a fault occurs, turning the switch to OFF and then back ON will reset the fault. Figure 3: ON/OFF switch, vertical position Revision: 02 Page 5 of 12... -
Page 6: Pump Priming (Cgs Only)
Pump Priming (CGS only) 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 piping is full of fluid, the pump suction line is “flooded”. In some cases, this flooded suction will automatically prime the pump. -

Page 9: Adjusting Alarm Set Points
Adjusting Alarm Set Points Purpose: When the CWS/CGS is in Auto mode, it will automatically switchover to city water backup on high temperature and low flow. The high temperature alarm set point is the supply temperature threshold at which switchover to city water backup is triggered. On units with a flow transducer, the low flow alarm set point is the threshold at which switchover to city water backup is triggered. -
Page 10: Units Of Measure
Units of Measure Purpose: Several combinations of units of measure are available depending on what is most useful. The following units of measure are available: • CAN (°C, psi, GPM) • UK (°C, bar, IGM) • USA (°F, psi, GPM) •... -
