12. SUPPLY POWER. Apply power to the monitor. It is universal voltage and accepts 100 to 240 volts AC.
13. CONFIGURE ZONES: Set up all zones based on your application needs. Use the guidelines on the following
pages to set zone names, the number of zones, refrigerant type, alarm limits, and sample lengths for each
zone. If splitters are used on one or more zones:
a. Be sure to keep tubing lengths the same beyond the splitter.
b. DISTANCE (total) for a particular zone using a splitter should equal the tubing length up to the
splitter plus the length of any ONE of the split tubing trunks (not the sum of all split trunks).
c. Note that a leak reading from a zone with split trunks may be lower than a reading from a non-split
trunk due to possible dilution from other pickups (splits) on that trunk. Alarm levels should be
adjusted accordingly.
