Installation 

!

WARNING

Only qualified personnel should install 

or service a regulator. Regulators 

should be installed, operated and 

maintained in accordance with 

international and applicable codes 

and regulations and Emerson Process 

Management Regulator Technologies, 

Inc. instructions.

If the regulator vents fluid or a leak 

develops in the system, it indicates that 

service is required. Failure to take the 

regulator out of service immediately may 

create a hazardous condition.
Personal injury, equipment damage or 

leakage due to escaping fluid or bursting 

of pressure-containing parts may result 

if this regulator is overpressured or 

is installed where service conditions 

could exceed the limits given in the 

Specifications section, or where 

conditions exceed any ratings of the 

adjacent piping or piping connections.
To avoid such injury or damage, provide 

pressure-relieving or pressure-limiting 

devices (as required by the appropriate 

code, regulation or standard) to prevent 

service conditions from exceeding limits.
Additionally, physical damage to the 

regulator could result in personal injury 

and property damage due to escaping 

fluid. To avoid such injury and damage, 

install the regulator in a safe location.

1. The pressure/temperature limits in this installation guide or any applicable standard limitation should not be exceeded.

2. For stability or overpressure protection, a pressure reducing regulator may be installed upstream of the pilot according to the Installation section.

3. Type 61H pilot used with a 99 Series regulator can handle a maximum inlet pressure of 27.6 bar / 400 psig.
