WARNING
GENERAL SAFETY GUIDELINES
p) The power must be off when switching the recovery valve.
q) If the tank pressure exceeds 21 bars, use the storage tank cooling method to reduce the tank
pressure. (See Page 20 cooling method)
r) To maximize recovery rates, use the shortest possible length of 3/8" or larger hose. A hose no longer
than 0.9 meter is recommended.
s) When recovering large amounts of liquid, use the Liquid Push/Pull method. (See page 19 “System
Push/Pull method”)
t) After recovering, make sure there’s no refrigerant left in the unit. Read the Self-Purging Method
carefully. Liquid refrigerant remained may be expanded and destroy the components.
u) If the unit is to be stored or not used for any length of time, we recommend that it is completely
evacuated of any residual refrigerant and purged with dry nitrogen.
v) To avoid refrigerant losing, we suggest to use a hose with a stop valve.
