First-time chiller turn-on procedure

The first-time turn-on procedure should be similar for use with other chillers.
Filling the Reservoir
1. Remove the filler cap from the reservoir
2.
Using a funnel, add Optishield Plus mixture (90% distilled water, 10% Optishield
Plus) until it reaches the MAX line on the reservoir's fluid level gauge. If Optishield
Plus is not allowed due to local regulations, use Optishield original formula.
3.
When full, remove the funnel, but do not replace the cap at this time.
Electrical Power
Plug the Chiller's power cord into an appropriate electrical outlet. Place the Circuit

Check for leaks
1.
Once the pump is turned on, check all of the connectors to see if there is any
leakage. If a leak is observed, turn off the pump immediately and fix the leak.
