Installation Instructions
Required Tools
•
Small, flat-blade screwdriver
NOTE: Normally, replacing restrictors or connectors
will not affect calibration.
Before troubleshooting (Table 1), ensure that:
1. The supply pressure at the unit is constant
(± 2 psi) 22 psi (152 kPa).
2. All transmitter inputs being used are between
3 and 15 psi (21 and 103 kPa).
3. Only one restrictor (internal or external)
supplies each transmitter.
4. The transmitter calibration is correct.
