If the Initial Fill Mode message appears the chiller needs fluid
before it will start.
Required minimum level values depend on the chiller's heater size,
see below.
If the Level is below the required amount Add Fluid will be dis-
played and flash until the required level is achieved, then Add Fluid
will extinguish.
For all chillers, the pump will not start until the level is above 15%.
Once the level is above the required amount for five minutes, as the
pump purges the system, the chiller will start.
If desired, press esc to exit the initial fill mode and start the
compressor.
