CHAPTER 20

CLEANING AND MAINTENANCE

INTRODUCTION

This chapter provides the information necessary for the user to perform the basic
maintenance of instrument cleaning, fuse replacement, and general preventative
maintenance. There are no internal adjustments or calibration settings that may be done by
the user without voiding the warranty.

REFER ALL SERVICING TO A QUALIFIED SERVICE REPRESENTATIVE!

It is recommended that periodic (every five years) re-calibration of the CAPTUS® 600 be
performed by Capintec’s Authorized Service Center to guarantee the instrument’s high
reliability is maintained. Contact the Capintec’s Authorized Service Center in Pittsburgh for
servicing or re-calibration at 1-800-227-6832.

CLEANING INSTRUCTIONS

CAUTION

DISCONNECT THE POWER BEFORE CLEANING.

TO AVOID ELECTRICAL SHOCK OR DAMAGING OF THE CAPTUS® 600, NEVER GET
WATER OR LIQUIDS INSIDE THE DETECTOR HOUSINGS OR THE READOUT
ENCLOSURE.

DO NOT USE AN AEROSOL DISPENSOR TO SPRAY THE EQUIPMENT WITH ANY
CLEANING SOLUTION OR LIQUID.

TO AVOID DAMAGING THE CASE OR DISPLAY SCREEN, DO NOT USE AROMATIC
HYDROCARBONS, CHLORINATED SOLVENTS, OR METHANOL-BASED CLEANING

SOLUTIONS.

DO NOT USE ANY FORM OF SCRAPER TO CLEAN THE FRONT FACE OF THE
DETECTOR, AS THE NaI CRYSTAL MAY BE DAMAGED.

• FLOOR STAND: Use a soft cloth that is lightly dampened with water, window
cleaner, or a mild detergent. Wipe the surfaces as necessary to remove dust or
smudges.

November 07 CLEANING AND MAINTENANCE 20-1

CAPINTEC, INC. CAPTUS® 600

• DETECTORS: Use a soft cloth that is lightly dampened with water, window cleaner,
or a mild detergent. Wipe the front surface and or the well as necessary to remove
smudges of surface contamination.

Note: If contamination is suspected, dispose of the cleaning cloth in an approved
container for contaminated materials.

• POINTER ASSEMBLY: Use a soft cloth that is dampened with propanol alcohol to
sterilize or clean the black pointer and assembly.

• READOUT: Wipe down with a damp cloth; do not use solvents or aerosol cleaners.

• PRINTER: Wipe down with a damp cloth; do not use solvents or aerosol cleaners.
Wipe the outside surfaces of the printer case to remove the dust, smudges, and
stains. The interior of the printer does not require cleaning.

PREVENTATIVE MAINTENANCE

The Quality Assurance Tests described in CHAPTER 6: ACCEPTANCE & QUALITY
ASSURANCE TESTS, SECTION: QUALITY ASSURANCE TESTS, should be performed
periodically as stated.

Tests must be performed in an environment where the temperature is stable within a range
of +50°F to +85°F (+10°C to +30°C) and the maximum relative humidity is 90% non-
condensing. The unit should be powered-up for at least one-half hour prior to performing any
measurements. No other precautions need to be observed.

CAUTION
If these environmental requirements are not followed,

the instrument may display erroneous readings.

Note: Never put a sharp instrument like a pen into the Well or Collimator. If the aluminum
coating of the NaI Detector is scratched, allowing light and moisture to penetrate, the
detector will be ruined. The rod source is plastic and can be safely placed against the
surface of the detectors when handled carefully.

If the unit fails to pass Auto Calibration Test or any other test, the user should not attempt to
perform any adjustments to the system. In this event, please contact Capintec’s Authorized
Service Center for further assistance.

The Quality Assurance tests should be immediately performed if:
• The equipment has been subjected to extreme physical stress,
• Liquids enter the readout unit, and/or Probe and Well detectors, or
• Any cable shows signed of damage

20-2 CLEANING AND MAINTENANCE November 07

CAPINTEC, INC. CAPTUS® 600

Collimator Block Inspection

Once a year, the Collimator Mounting Block (1) should be inspected for the following:
• excessive play between the Spring-Arm shaft (2) and the Collimator Mounting Block,
• excessive play between the Collimator pin (3) and the Collimator Mounting Block.

If there is excessive play or the knob(s) cannot be tightened, contact Capintec’s Authorized
Service Center for a information on replacement items, instructions or on-site service.

Figure 20-1

WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS INJURY

OR PRODUCT MALFUNCTION.

SERVICING

The system is covered by a one year limited warranty, under normal conditions of use.

Other than the Readout Unit and Isolation Transformer’s fuses (see Fuse Servicing in this
chapter), there are no user serviceable parts contained in the system.

Every five years, the system should be returned to Capintec’s Authorized Service Center for
a complete verification.

FUSE SERVICING

CAUTION

For continued protection, replace only with
same type and rating of fuse(s)

Power Line Fuses

The power line fuses are located on the front side of the Isolation Transformer Unit directly
below the main power cord connector. The type and rating of these 2 fuses are listed on the
label that is located on the top of the Isolation Transformer Unit.

To change these fuses:

1. Turn off the 2 power switches that are located on the back of the Readout Unit and on
the right side of the Printer.

2. Unplug the power cord that is connected to the front of the Isolation Transformer Unit.

3. Use a small screwdriver to pry open the tab of the fuse drawer that is located directly
below the power cord connector. The drawer will drop down to expose the ends of the
2 fuses. (Refer to Figure 20-3)

4. Remove the blown fuse(s) from the holder and replace it (them) with the fuses
specified on the top label.

5. Rotate the fuse drawer to the upright position and push the drawer back into the fuse
holder.

Figure 20-3

6. Reconnect the power cord to the Isolation Transformer Connector and turn on the 2
power switches (Readout Unit and Printer).

7. Verify the CAPTUS® 600 System is functioning correctly by performing the Daily
Tests.

Readout Unit Fuses

Two fuses are located in the power entry module next to the power cord connector on the
back panel of the Readout Unit. The type and rating of these fuses are listed on the label
located on the back panel of the Readout Unit.

To change these fuses:
1. Turn off the CAPTUS® 600 power switch and unplug the line cord from the power
entry module.

2. Insert the tip of a small flat bladed screwdriver into the notch of the power entry
module just to the left of the switch. Twist the screwdriver to open the fuse cover
door. (Refer to Figure 20-4).

3. To remove the first of the two fuse carriers, insert the tip of the screwdriver behind the
arrow and pull it out. Repeat this process for the second fuse.

4. Remove the blown fuse(s) from the carrier and replace it (them) with the fuses
specified on the back label.

5. Re-insert the fuse carriers with the arrows pointing up (Refer to Figure 20-4).

Figure 20-4
6. Close the fuse cover door and snap it into place.
7. Replace the line cord and turn on the power switch for the CAPTUS® 600.
8. Verify the CAPTUS® 600 System is functioning correctly by performing the Daily

Tests.

Printer Fuse
The printer fuse is not accessible from the outside of the printer case and must be replaced
by a qualified service representative.
