PRESSURE GAUGES
Both the high- and low-side gauges are equipped with red “follower” needles to
show either the maximum or minimum pressure reached during operation.
The
“follower” is carried to the highest or lowest operating pressure, and stays there
when the regular (black) needle indicates other pressures.
1. The follower on the low-side gauge should be adjusted so it rests on the
bottom side of the black needle when the A/C system is not in operation.
2. The follower on the high-side gauge should be adjusted so it rests on the top
side of the black needle when the A/C system is not in operation.
When set up this way, the follower will be carried to the highest pressure or lowest
pressure registered by the individual gauge.
NUMBER KEYS
Use these keys to change the evacuation time, vacuum level, or recharge weight if
you want an amount different than the default shown on the display. These keys
are also used to enter other numeric values, such as your area’s elevation above
sea level.
UP/DOWN AND LEFT/RIGHT ARROW KEYS
Pressing the UP/DOWN and RIGHT/LEFT keys moves the cursor on the screen
in that direction (up, down, right, or left). In addition, during numeric
programming, pressing the
UP arrow increases the number; pressing the DOWN
arrow decreases the number.
