Unit Startup

When the cooling requirement is satisfied, the UCP originates a “Shutting down” signal. The inlet guide vanes are driven closed for 50 seconds, and the unit enters a 3- minute post-lube period. The compressor motor and condenser water pump starter are de-energized immediately, but the oil pump continues to run during this 3-minute interval; the evaporator pump will continue to run.

Once the post-lube cycle is done, the unit returns to auto mode.

Seasonal Unit Start-Up

1.Close all drain valves, and re- install the drain plugs in the evaporator and condenser headers.

2.Service the auxiliary equipment according to the start-up and maintenance instructions provided by the respective equipment manufacturers.

3.Vent and fill the cooling tower, if used, as well as the condenser and piping. At this point, all air must be removed from the system (including each pass). Then close the vents in the condenser water boxes.

4.Open all of the valves in the evaporator chilled water circuit.

5.If the evaporator was previously drained, vent and fill the evaporator and chilled water circuit. When all air is removed from the system (Including each pass), close the vent valves in the evaporator water boxes.

6.Lubricate the external vane control linkage as needed.

7.Check the adjustment and operation of each safety and operating control.

8.Close all disconnect switches.

9.Perform instructions listed in “Daily Unit Start-up” section.

WARNING

Live Electrical

Components!

During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.

WARNING

Toxic Hazards!

•Do not run evaporator water pump longer than 30 minutes after the chiller is shutdown.

•Ensure that the evaporator is isolated from the hot water loop

before changeover to heating mode.

Do not allow the chiller to increase above 110°F in temperature while unit is off. Failure to prevent high chiller temperature will cause the inside pressure to rise. The rupture disk is designed to relieve and discharge the refrigerant from the unit if the pressure in the evaporator exceeds 15 PSIG (103.4 Kpa). A significant release of refrigerant into a confined space due to a rupture disk failure could displace available oxygen to breathe and cause possible asphyxiation. Should a rupture disk fail, evacuate the area immediately and contact the appropriate rescue or response authority. Failure to take appropriate precautions or react properly to a potential hazard could result in death or serious injury.
