NOTES:
1. Not applicable to the Type AV4.
2. Tested according to ISA-S75.13-1989.
3. Operation below specification (not recommended) will increase stroke time.
4. For operation below 4.4×C (40×F, )dew point of the supply air must be -7.7×C (18×F) lower than the lowest expected operating temper-
ature.
