ƽ WARNING
Hazard of Explosion!
Never use an open flame to detect gas leaks. Explosive conditions may occur. Use a leak test
solution or other approved methods for leak testing. Failure to follow recommended safe leak
test procedures could result in death or serious injury or equipment or property-only-damage.
[ ] Leak test the system. Refer to the “Refrigerant Piping” section for recommended procedures.
EVP Chilled Water Piping Requirements
[ ] Install properly sized chilled water pipe between the EVP chiller and the supporting equipment.
Refer to the “Chilled Water Piping” section for recommended system components and guidelines.
Ensure that the recommended components have been installed:
Water pressure gauges (with isolation valves)
Thermometers
Chiller isolation (shutoff) valves in the solution inlet and outlet piping
Strainer in the solution inlet piping
Balancing valve
Flow switch in the solution outlet piping
Chilled solution sensor well and sensor in the solution outlet piping
Freezestat well and freezestat bulb in the chilled solution outlet piping
Chiller drain plug, or drain piping with a shutoff valve
[ ] Flushing the chilled solution piping system, if applicable.
Note: If using an acidic, commercial flushing solution, to prevent damage to the internal
evaporator components, flush all chilled solution piping before making the final connection
to the EVP chiller.
[ ] Connecting the chilled solution piping to the chiller.
[ ] Install heat tape and insulation, if necessary, to protect any exposed solution piping from external
freezing conditions.
Main Electrical Power Requirements
ƽ WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
[ ] Verify the power supply meets the required power requirements of the system.
[ ] Install power wiring in accordance with all applicable codes.
[ ] Install and connect properly sized power supply wiring, with over current protection, to the main
power terminal block (1TB1) or to an optional factory mounted nonfused disconnect switch (1S1)
in the control panel.
[ ] Install and connect properly sized power supply wiring, with over current protection, to the
proper termination point in the air handling unit (If applicable).
[ ] Install and connect properly sized power supply wiring, with over current protection, to the
proper termination point for the chilled solution pump (EVP units only).
