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 cap located on the top of the Chiller and, using a funnel, add fluid until it is
approximately 2 inches (5.1 cm) below top of reservoir.
2. 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 circuit breaker located on the rear panel of the Chiller to 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 circuit breaker 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.
NOTE: When adding fluid to the unit for the first time, prime the pump by pressing the Power Button to turn
power ON, letting the Chiller run for 3 seconds, and the pressing the Power Button again to turn power OFF.
Repeat this ON and OFF procedure three times.
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.
