The items shown in Table 25 are for the first barrel in the unit only. The list includes additional components with
their related barrel number, i.e. Hot Gas Sol #2, etc.
!
CAUTION:
The compressor can suffer damage if it is allowed to run without either a hot gas defrost or liquid line solenoid
open. The software is designed to turn on the hot gas solenoid for a barrel to prevent damage from occurring.
To move between one set of barrel parameters to the next, press the Right or Left arrow keys. This moves the high-
light to the first entry of the second barrel, etc.
Totals Menu
The Totals menu (Figure 23) shows the cumulative run time of the system, a component of the system or an error.
Some individual items may be reset, where available, by highlighting the item and pressing the RESET button. The
RESET button is only displayed for items that may be reset, such as hours since the motor seal was changed or the
number of compressor cycles. Pressing the BACK button returns to the Choose menu and saves the changes. The
description of each item in the Totals list is shown in Table 26.
