IV. Installation: Electrical, Connection to Outdoor Chiller
Electrical
•Comply with proper local electrical codes.
•Contact a licensed electrician to perform the electrical installation.
•The electrician should verify that the wiring is adequate in the installation area.
•Refer to the heat exchanger specification document or the unit’s nameplate label for detailed
electrical requirements.
•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.

Phase monitor: Heat exchangers include a phase monitor. Refer to the fault indicators provided on
the phase monitor and contact a licensed electrician to correct any faults.

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. Connections are 1-to-1 and are labeled.

V. Installation: Filling the Reservoir
•Close all supply and return ball valves.
•Remove the cap from the reservoir.
•Fill the reservoir with drinking/spring water, up to just below the overflow drain port.
•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.

VI. Installation: Final Checks
Phase Monitor
Check: If the voltage and phase from the service disconnect is correct, the phase monitor should
have a solid green LED. If the phase monitor has a solid or flashing red LED, contact a licensed
electrician to correct the fault.
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.

Pre-Startup Checklist
Directions: Email completed checklist to se[email protected] at least 10 days in advance of start-up.
Model: Serial Number:__________________________
Site Name:_____________________________ Address:_________________________________
_____________________________
Location:
❑Unit is securely mounted and level.
❑Minimum of 36” clearance exists on the front of the unit, and minimum of 18” clearance exists above
and to the sides of unit.
Fluid Connections:
❑All piping is of non-ferrous materials and complies with local codes.
❑Beginning and end of hard pipe runs are terminated with vibration isolators or a short length of hose.
❑Isolation ball valves are installed between WW and building water or glycol loop connections.
Electrical Power:
❑Incoming voltage and circuit breaker size for incoming power match unit’s nameplate.
❑Confirm proper electrical power and phase by checking the phase monitor’s status indicator.
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.
❑Additional drinking/spring water is on-hand for service contractor to top off system when start-up is
performed.

VII. Optional Modbus or BACnet Communication Capability
Building Management System
Purpose: Some facilities have centralized building monitoring systems (BMS). The exchanger can be
monitored from the 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.

VIII. Startup
Phase Monitor
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.
The phase monitor will show a solid green LED if the voltage and phase from the service disconnect
is correct. If the phase monitor has a solid or flashing red LED, contact a licensed electrician to
correct the fault.
•Reversal is caused by the 3 lines being in an improper sequence. To correct a reversal, switch
any 2 of the 3 line connections. Make this switch at the disconnect, not in the heat exchanger.
•Loss/unbalance is caused by a percentage difference in voltage between the 3 lines relative to
each other.
•Undervoltage is caused by a percentage difference in voltage between the 3 lines compared to
the line-line voltage knob setting.
•Overvoltage is caused by the voltage between the 3 lines being >10% over the line-line
voltage knob setting.

ON/OFF Switch
Location: The heat exchanger has a rotary ON/OFF switch located on the left side of the unit.
Operation: Rotate the switch to make the heat exchanger 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. Note that city water backup is active while switch is in the OFF position.

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. When the heat exchanger is turned ON, the pump will run. If the
controller display shows the pump generating pressure, then the pump is primed.
If the pump pressure gauge shows a low pressure <10 psi, then the pump did not automatically
prime. Follow the procedure below.
1. Identify the priming plug on the face of the pump head
2. Use a wrench to loosen the priming plug slightly. The plug should remain threaded into the
port, but air and liquid should be able to escape.
3. Allow air and a small amount of fluid to escape
4. Tighten the priming plug
