A. Use shortest length of 3/8" (inside) diameter refrigeration hose on suction side of unit to vapor
port on tank.
B. Use 3/8" (inside) diameter refrigerant hoses from system liquid service valve to liquid port on
tank.
C. If refrigerant is clean, remove all suction side filters, screens, etc...
D. Remove all Schrader type valve cores and any valve depressors from the hoses and service
valves.
