Calibration Kit
In order to perform the calibration procedure the HFR
system must have circulation lines going from the sys-
tem fluid manifold back to the tanks. If the system does
not have circulation lines, a calibration kit must be pur-
chased and installed. See
Flow Meter Calibration Kits
for Hydraulic Dispense Valves on page 17 for the cor-
rect calibration kit number to order for your dispense
valve.
This procedure applies to the L-Head, S-Head and
GX-16 calibration kits only. See page 17 for part refer-
ence numbers.
1. Perform HFR Pressure Relief Procedure . See
HFR operation manual for detailed instructions.
2. Perform dispense valve Pressure Relief Proce-
dure . See dispense valve manual, page 2, for
detailed instructions.
3. Verify all air, hydraulic, and material pressures have
been relieved before continuing.
4. Perform HFR Shutdown procedure. See HFR oper-
ation manual for detailed instructions.
5. If material hoses from the dispense valve are con-
nected to the HFR system, disconnect them from
the system fluid manifold to enable removing the
blue pumpline shield.
6. Remove blue plastic shield that covers the center of
the pumpline.
7. Remove A (Red) and B (Blue) circulation fittings
from the fluid manifold. See F
