1. Clean the lines upstream from the valve. Remove

any debris larger than 0.06" (0.015 mm).

2. Alignthevalve’sowindicatorwiththesystem

CAUTION

To prevent condensation from dripping onto the

actuator housing, mount the valve with the actuator

in the upright position or, at most, at a 45° angle.
