Table 4. Normal Operating Pressures − Liquid +10 and Vapor +5 PSIG
Use table 4 as a general guide when performing maintenance checks. This is not a procedure for charging the unit (Refer
to Charging / Checking Charge section). Minor variations in these pressures may be expected due to differences in instal-
lations. Significant differences could mean that the system is not properly charged or that a problem exists with some
component in the system.
