Startup
Facility Water Flow (water-cooled units only)
1. Open the valves to the facility water supply and return.
2. Check for leaks.
Filling the Reservoir
1. Remove the reservoir cover plate (located on the top of the Chiller) and reservoir cap.
2. Using a funnel, add fluid until it is approximately 2 inches (5.1 cm) below top of reservoir.
3. Once the fluid level is about 2 inches (5.1 cm) below the top of the reservoir, remove the funnel but do not
replace the cap at this time.
Starting Process Fluid Flow
1. Place the Power Switch located on the rear panel of the Chiller in the ON position. The display on the front
panel will respond by showing standby (....). If there is no response, check that the unit is connected to
working electrical power and that Power Switch on the rear of the Chiller is in the ON position.
2. Press the Power Button on the front panel. The system startup sequence will begin and proceed as follows:
•
The pump will turn on and fluid will begin circulating through the system.
•
The set point temperature will appear briefly on the Temperature Display; after a few seconds, it will be
replaced by the actual fluid temperature.
•
15 to 20 seconds after power up, the compressor will begin operating.
3. Check for leaks.
4. With the pump running, the reservoir’s fluid level will drop as the process and/or process cooling lines fill
with fluid. Slowly add fluid to the reservoir until the liquid level remains stable.
5. Replace the reservoir cap and cover plate.
