Pressure Service Ports; Table 12 Cooling Pressures - Bard WG Series Installation Instructions Manual

34. PRESSURE SERVICE PORTS

High and low pressure service ports are installed on
all units so that the system operating pressures can
be observed. Table 12 outlines expected pressures at
various indoor and outdoor temperatures.
This unit employs high-flow Coremax valves instead of
the typical Shrader type valves.

WARNING! Do NOT use a Schrader valve core removal
tool with these valves. Use of such a tool could result
in eye injuries or refrigerant burns!
To change a Coremax valve without first removing the
refrigerant, a special tool is required which can be
obtained at www.fastestinc.com/en/SCCA07H. See the
replacement parts manual for replacement core part
numbers.
