WARNING! - SAFETY CONSIDERATIONS
Sudden release of compressed or stored gas can cause personal
injury. Always vent the system before making pressure
connections or disconnections. Exercise standard physical
protection practices such as eye protection, gloves, protective
clothing, etc.
To prevent the potentially hazardous release into the atmosphere
of substances introduced into the pneumatic system by the user,
no relief valves are provided in the QuikCal 90 Pressure Module.
Consequently, if a module is overpressurized, the sensor will be
damaged.
FITTING INSTALLATION
All pneumatic connections to the QuikCal 90 Module are made via
1/8”-27 NPT threads in the pressure port. Adapter fittings may be
used for 1/4”-18, straight 10-32 threads or any other size fittings to
match the field connections.
To install a fitting in a module pressure port:
1) Apply Teflon tape or pipe dope to the fitting threads (Teflon tape
not recommended with stainless steel fittings)
2) Carefully install the fitting in the pressure port on top of the
module
3) Use a 5/8” wrench to support the pressure module port and a
second wrench to tighten the fitting
4) Check for leaks
