1. Introduction
The PV210 is a portable source of pressure and vacuum.
Each pump includes a pressure/vacuum selector, a volume
control for fine adjustment and an adjustable pressure relief
valve to prevent damage to sensitive instruments.
2. Operation
WARNING
Before applying pressure, make
sure all connections are correct and
equipment is internally clean and free from
damage.
Make sure that all equipment is to the correct
pressure rating.
Do not exceed the maximum operating
pressure stated in the specification.
Observe the relevant health and safety
precautions.
CAUTION
If PTFE tape is used to seal NPT
threads, ensure that only a sufficient amount
is used to achieve pressure seal. If excess
tape is used, particles can become loose
during the connector mating process and
enter the pump, potentially leading to loss of
pump performance or pressure leaks.
INFORMATION
has a small displacement, only use the PV210
to pressurize small volumes.
Note: Wherever possible, use o-ring seals in the BSP
connection ports this is the recommended method of
sealing.

2.1 Hose/Adaptors (Figure A1)
To attach a hose (5) and adapter (6) to a connector (4),
turn the knurled nut on the connector counterclockwise.
2.2 Pressure Release Valve (Figure A1)
Use this (1) to reduce or release the pressure in the
system. The amount of turn sets the rate to release the
pressure. Only minimum force is necessary to seal the
system.
