WARNING

!

Failure to follow these instructions or
to properly install and maintain this
equipment could result in an explosion

and/or re causing property damage and

personal injury or death.

Fisher® regulators and integral True­Monitor regulators must be installed,
operated, and maintained in accordance
with federal, state and local codes, rules
and regulations, and Emerson Process
Management Regulator Technologies, Inc.
(Regulator Technologies) instructions.

If the regulator vents gas or a leak
develops in the system, service to the unit

2

may be required. Failure to correct trouble
could result in a hazardous condition.

Call a gas service person to service the

unit. Only a qualied person must install

or service the regulator.

Description

The Type TM600 Integral Monitor provides

True-Monitor Protection by taking the place of a

separate service regulator on monitor applications.
Intended for commercial and light industrial
applications, it can be used for pressure reducing
service on natural, manufactured, or LP gas. To be
functional, Type TM600 must be mounted on primary

regulators with orices up to 1 inch / 25 mm. The

Type TM600 is not currently orderable separate from
a service regulator.

Principle of Operation

As downstream pressure registers under the main
diaphragm of the Primary Regulator, it also registers
under the diaphragm of the Integral Monitor. If for
any reason the Primary Regulator ceases to regulate
downstream pressure below the setpoint of the
Integral Monitor, the monitor will begin to throttle the

ow and maintain a downstream pressure below the
maximum pressure indicated in Tables 1 through 7.
If the Primary Regulator is equipped with a token

internal relief valve, it will begin to relieve to provide
an indication via smell that the Integral Monitor is
controlling the downstream pressure. As downstream
demand decreases, the Integral Monitor closes to
maintain a downstream pressure below the maximum

value given in Tables 1 through 7. As downstream

demand increases, the Integral Monitor opens to

supply additional gas ow as needed to maintain

downstream pressure.

Installation

WARNING

!

All vents should be kept open to permit

free ow of gas to the atmosphere.

Protect openings against entrance of
rain, snow, insects or any other foreign
material that may plug the vent or vent
line. When installing outdoors, point the
spring case vent of the Primary regulator
and Integral Monitor downward to allow
condensate to drain. This minimizes the
possibility of freezing and accumulation
of water or other foreign materials
entering the vent and interfering with
proper operation.

Under enclosed conditions or indoors,
escaping gas may accumulate and be
an explosion hazard. In these cases,
the vents should be piped away from the
regulator to the outdoors.

CAUTION

The Type TM600 Integral Monitor has an
outlet pressure rating lower than their
inlet pressure rating. Overpressuring
any portion of the regulators beyond

the limits in Specications section and

Tables 1 through 8 may cause leakage,
damage to regulator parts, or personal
injury due to bursting of pressure­containing parts.

General Installation Instructions

Before installing the Type TM600:

• Check for damage, which might have occurred

during the shipment.

• Check for and remove any dirt or foreign

material, which may have accumulated in the
regulator body.

• Blow out any debris, dirt, or copper sulfate in the
copper tubing and the pipeline.

If the Type TM600 is exposed to an
overpressure condition, it should be
inspected for any damage that may have
occurred. Integral Monitor operation
below these limits does not preclude
the possibility of damage from external
sources or from debris in the pipeline.

4

• Apply pipe compound to the external threads

of the pipe before installing the pipe into the
Type TM600 vent or external control line port.

• Make sure gas ow through the primary

regulator is in the same direction as the arrow
on the body. “Inlet” and “Outlet” connections are

clearly marked.

e.g., for a Primary regulator setpoint of 7 inches w.c. / 17 mbar, the Integral Monitor can also be set at 21 inches w.c. / 52 mbar, 1 psig / 69 mbar, or higher.

Installation Location

• The installed Type TM600 should be adequately
protected from vehicular trafc and damage from

other external sources.

• Install both Primary and Type TM600 Integral
Monitor with both vents pointing vertically

down, see Figure 4. If the vents cannot be

oriented in a vertically down position, then
Type TM600 must be installed under a separate
protective cover. Installation with the vents down

allows condensation to drain, minimizes the entry

of water or other debris from entering the vent, and

minimizes vent blockage from freezing precipitation.

• Do not install Type TM600 in a location where

there can be excessive water accumulation or
ice formation, such as directly beneath a down

spout, gutter, or roof line of building. Even

a protective hood may not provide adequate
protection in these instances.

• Install the Type TM600 so that any gas discharge
through the vents or vent assemblies is over
3 feet / 0.91 meters away from any building opening.
