MAINTENANCE

This unit requires very little preventive
maintenance other than a daily cleaning. The
chart recorder is a precision instrument and can
be damaged by rough or careless handling. It will

also need to be recalibrated at regular intervals
Most Hospitals and Schools have a recalibration
program for other equipment and this item has
only to be added.

NOTE: It is not necessary to remove the valve
from the pipeline for repairs.

WARNING: Turn off electrical power supply and

depressurize valve before making repairs.

Cleaning

All solenoid valves should be cleaned periodically.
The time between cleanings will vary depending
on the medium and service conditions. In general,
if the voltage to the coil is correct, sluggish valve
operation, excessive noise or leakage will indicate
that cleaning is required . Clean valve strainer or
filter when cleaning the valve.

Preventive Maintenance

1. Keep the medium flowing through the valve as

free from dirt and foreign material as possible.

2. While in service, the valve should be operated

at least once a month to insure proper
opening and closing.

3. Depending on the medium and service

conditions, periodic inspection of internal
valve parts for damage or excessive wear is
recommended. Thoroughly clean all parts.
Replace worn or damaged parts. However, for
best results, replace all parts as supplied with
a Rebuild Kit.

Causes of Improper Operation

"click" signifies that the solenoid is operating.
Absence of the "click" indicates loss of power
supply . Check for loose or blown fuses, open
circuited or grounded coil, broken lead wires
or splice connections.

2.

Burned-Out Coil:

Check for open-circuited
coil. Replace coil as necessary. Check supply
voltage; it must be the same as specified on
nameplate.

3.

Low Voltage:

Check voltage across the coil
lead. Voltage must be at least 85% of
nameplate rating.

4.

Incorrect Pressure:

Check valve pressure.
Pressure to valve must be within range
specified on nameplate.

5.

Excessive Leakage:

Disassemble valve and
clean all parts. If leakage continues, replace
all parts as supplied with a Rebuild Kit.

4. Unscrew solenoid base sub-assembly and

remove core assembly, core spring, and
solenoid base gasket.

5. Remove bonnet screws, valve bonnet, piston

assembly, lip seal, support, inner and outer
body gaskets.

6. All parts are now accessible to clean or

replace; Replace worn or damaged parts.
However, for best results, replace all parts as
supplied with an Rebuild Kit.

Valve Reassembly

1. Reassemble in reverse order of disassembly.

Use exploded view for identification and
placement of parts.

2. Lubricate all gaskets with DOW CORNING

111® Compound lubricant or an equivalent
high-grade silicone grease.

3. Position support and inner and outer body

gaskets in valve body.

4. Position lip seal, flanged end up, onto piston

assembly. Install piston assembly with lip seal
into support in valve body cavity.

Torque bonnet screws in a crisscross manner
to 95 ±10 inch-pounds (10,7 ±1,1 newton­meters).

6. Replace solenoid base gasket, core

assembly, and solenoid base sub-assembly.
Torque solenoid base sub-assembly to 175

±

25 inch-pounds (19,8 ±2,8 newton-meters).

7. Replace solenoid enclosure and retaining clip.

8. Restore line pressure and electrical power

supply to valve.

9. After maintenance is completed, operate the

valve a few times to be sure of proper
opening and closing.

Calibration Mode (CAL)

The chart recorder is a sensitive instrument that requires periodic maintenance and recalibration.
Temperature, humidity, vibrations, and handling all contribute to causing errors in temperature reading.

Regular inspections a recalibration by a trained service technician with the proper equipment will keep the
unit accurate and reliable.

CAL 9 will calibrate the pen to the chart. This is the only calibration and you can do it without training and
equipment. See page 46-49 (MRC 7000 Manual) for instructions.
