PENBERTHY MODEL FHS AUTOMATIC LIQUID HEATING SYSTEM

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

4 INSTALLATION

Installation should only be undertaken by
qualified, experienced personnel who are
familiar with this equipment and have read
and understand thoroughly all the instructions
in this manual. The user should refer to the
relevant technical data sheet or product
proposal to obtain dimensional information for
the specific size and model of FHS.
Check Figure 1 for the location of the liquid inlet
and outlet, steam inlet and air inlet connections
to insure correct hook up.

4.1 Mounting

Although the FHS can be oriented in any
position, it is recommended to position the
steam valve actuator horizontally. In this
manner, the thermometer dial will be upright,
the steam piping and steam ring heater will
be in a position to favor removal of condensate
at start up, the steam line strainer will point
downward, and the temperature controller will
be located as recommended by the controller
manufacturer.

4.2 Effect of related piping and precautions

1. The FHS should be installed with piping and
fittings which provide minimum resistance
to flow. Pipe line friction losses must always
be a consideration when estimating FHS
performance.

2. It is recommended that provisions be made
for pressure gauge connections near the
liquid inlet and outlet, and the steam inlet
connections of the FHS. If performance
problems occur during operation, it may
be necessary to install pressure gauges to
identify the problem.

3. Steam must not have over 20°F (-7°C) of
superheat, or performance will differ from
that published in the relevant technical data
sheet or product proposal referred to above.

4. The steam line must be clean, insulated and
as short as possible to prevent condensation
and line friction losses.

5. Do not impose system piping loads on an
FHS. The unit is designed to be supported
by the liquid inlet and outlet and steam inlet
piping.

6. Provide the steam line with a hand-operated
valve for maintenance and emergency shut­off. The steam line should be provided with a
steam trap.

7. Provide an air line with an air pressure
regulator capable of maintaining
18 psig (125 kPaG) air pressure. Also, it is
recommended that an air pressure gauge
be installed in this line.

5 OPERATION

5.1 Pre-operational check

1. Ensure that all installation procedures have
been completed.

2. Ensure that any restrictions in the discharge
line have been removed.

3. Ensure that discharge line valves are fully
open.

4. Ensure that the manually operated steam
line valve is fully closed.

5. Ensure that the temperature controller
knob is set to the lowest possible reading
by turning it counterclockwise as far as it
willgo.

6. Ensure that the air pressure regulator valve
is shut off.

Note: When the control valve is completely
installed and connected and ready to be put
into operation, it is necessary for the user to
check for correct travel, freedom of friction,
and correct action (air-to-open) to match the
temperature controller. If adjustments are
necessary, follow all instructions printed in the
installation instruction manual prepared for the
specific actuator by its manufacturer.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

5.2 Operating

1. Turn operating liquid valve fully on and
establish full flow. Keep it on throughout the
entire operation process.

WARNING

Failure to maintain the liquid flow while operating
the FHS with steam can cause live steam to be
driven into the liquid piping, resulting in severe
personal injury or property damage.

2. Turn on the air pressure regulator and
adjust the air pressure knob to 18 psig
(125kPaG).

3. Set the knob of the temperature controller
at 120°F (49°C) and check for proper
operation of the steam valve, which should
be fully open in about 20 seconds time.
Ifthe steam valve does not open in about
20seconds, adjustment of the temperature
controller is necessary. Follow all steps
and precautions printed in the installation
instruction manual prepared for the specific
controller by its manufacturer.

4. Bleed out trapped air inside the pipe
cross where the thermometer is installed
by slightly loosening the thermometer
connection until liquid begins to drip out,
then retighten the thermometer in place.

5. Slowly and partially open the manually
operated steam line valve to first check for
leaks. If leaks are evident, close the valve,
allow the line to cool off, tighten connections
and repeat the procedure until all leaks are
stopped.

6. Turn the temperature controller knob to
100°F (38°C) to allow steam to flow while
checking for leaks. If leaks are evident,
shut off the steam supply, allow the line to
cool off, tighten connections and repeat the
procedure until all leaks are stopped.

7. Fully open the operated steam valve
manually.

8. Turn the temperature controller knob
gradually to the desired outlet liquid
temperature and allow the FHS to
stabilize. Compare the knob setting with
the thermometer reading and adjust if
necessary.

There are two distinct operating noise levels
typical of the FHS, within specific operating
conditions. For detailed information on these
operating conditions, request Emerson to
supply the relevant technical data sheet.

5.3 Shutdown

1. Turn the manually operated steam line valve
off in order to first lower the steam line
pressure as much as possible before shut
down.

2. Set the temperature controller knob to
the lowest possible reading by turning it
counterclockwise as far as it will go. This
will cause the steam flow control valve to
close fully.

3. Turn the air pressure regulator valve off
fully.

4. Gradually turn the operating liquid flow off
fully.

WARNING

Failure to maintain the liquid flow throughout
the shutdown procedure may cause live steam
to drive into the liquid piping, resulting in severe
personal injury or property damage.

6 MAINTENANCE

WARNING

Maintenance should only be undertaken by
qualified, experienced personnel who are
familiar with this equipment and have read and
understood thoroughly all the instructions in this
manual.
DO NOT proceed with any maintenance unless the
FHS has been relieved of all pressure or vacuum,
has been allowed to reach ambient temperature
and has been drained or purged of all fluids.
Failure to follow these instructions may cause
severe personal injury or property damage.

6.1 Preventative maintenance

The user must create maintenance schedules,
safety manuals and inspection details for each
specific installation of an automatic liquid
heating system.
