Description of Caution/ Warning Symbols

C a u t i o n

Failure to follow the procedures prescribed in this manual might result in

irreparable equipment damage. Important information about the operation
and maintenance of this instrument is included in this manual.

W A R N I N G

Warning means that unsafe use of the instrument could result in serious

injury to you or cause damage to the instrument. Follow the procedures
prescribed.

Warns that uninsulated voltage within the instrument may
have sufficient magnitude to cause electric shock.
Therefore, it is dangerous to make contact with any part
inside the instrument.

Warns that the instrument is susceptible to electro-static
dissipation (ESD) and ESD protection procedures should be
followed to avoid damage.

Indicates the connector is connected to earth ground and
cabinet ground.

W A R N I N G S

 Never use the HM675 Hydronic Manometer or accessories on

potable water systems or other systems which may be used to convey
fluids for human or animal consumption.

 Never charge non-rechargeable batteries by setting battery-type

selection switch to NiMH when using alkaline or other non­rechargeable batteries. Fire, explosions, or other hazards may result.

Appropriate caution/warning statements are used throughout the manual
and on the instrument that require you to take cautionary measures when
working with the instrument.

Caution

Warning

Caution or Warning Symbols

The following symbols may accompany cautions and warnings to indicate
the nature and consequences of hazards:

Carefully read each of the following safety warnings prior

to using the HM675 Hydronic Manometer.

vi Hydronic Manometer Model HM675

C a u t i o n s

 Never use the HM675 Hydronic Manometer to measure the pressure

of volatile, flammable, or otherwise hazardous fluids or gasses. The
instrument is not designed to be intrinsically safe, nor is it designed
for use with caustic or corrosive chemicals.

 Never connect the HM675 Hydronic Manometer or accessories to

systems which exceed the instrument’s maximum pressure

specification (300 psi; 2068 kPa).

 Observe proper safety precautions and wear appropriate personal

protective equipment, including gloves and eyewear, when working
on high pressure or high temperature systems. Ruptured or leaking
lines pose a potential risk of serious personal injury.

 When using the HM675 Hydronic Manometer, verify all hose

connections are secure prior to taking pressure measurements.
Loose connections may result in the discharge of pressurized water
or air, posing a potential risk of serious personal injury.

 Exercise caution when disconnecting the HM675 Hydronic

Manometer from a pressurized system. Water or air discharged under
pressure poses a potential risk of severe injury.

 Exercise caution in using the HM675 Hydronic Manometer near

electrical equipment. Water spray associated with purging or
disconnecting hoses presents a potential risk of damage to such
equipment.

 Thoroughly drain and dry the HM675 Hydronic Manometer hoses and

internal piping after each use. This will help in limiting the potential for
growth of hazardous microorganisms.

 Never plug into the instrument any power supply other than the one

provided with the instrument.

 Always make certain that the battery switch is in the correct position

for the type of battery being used (Alkaline/NiMH). Failure to do so
may result in Fire, Explosions or other hazard.

 Never use Alkaline and NiMH batteries together on the same

instrument.

 Always use the hoses with the provided Flow Restrictor connected in

line with the shut-off valves to prevent “Water Hammer.” Water
Hammer is a fast moving shock wave of pressure caused by sudden
changes in the system such as a valve being opened or closed or a
pump being turned on or off.
