The unit is equipped with a minimum (65 psig, 4.5 Bars)
pressure/check valve; no special procedure to main-
tain the unit reservoir pressure is required.
Unit Hot (No warm–up period is required):
1.
Close the air service valve (customer furnished)
between the main air system and the check valve

STOPPING THE UNIT:
1.
Close the air service valve (customer furnished)
between the main air system and the check valve
