 Instruction Manual

Installation

Location: The most uniform operating conditions and results will be obtained by placing the bath in an area remote from drafts, ventilating outlets, radiators, and other rapidly changing ambient conditions.

Cleaning: The interior of the bath, shelf platform, and cover should be washed with a mild detergent solution and rinsed with distilled water.

Electrical Connections: Important (Please Read Carefully.)

CAUTION: DO NOT connect bath to power supply unless bath is

filled with at least 1" of water and the line switch is in the "Off"

position. This will prevent the heater from burning out.

WARNING: For personal safety, this apparatus must be properly grounded.

The power cord of this instrument is equipped with a three-prong (grounding) plug which mates with a standard three prong (grounding) wall receptacle to minimize the possibility of electric shock hazard from this apparatus. The user should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded. Where a two-prong receptacle is encountered, it is the personal responsibility and obligation of the user to have it replaced with a properly grounded three-prong wall receptacle.

WARNING:DO NOT, under any circumstance, cut or remove the

third (ground) prong from the power cord. DO NOT use a two-

prong adapter plug.

Determine the total amount of current presently being used by other apparatus connected to the circuit that will be used for this unit. It is critical that the added current demand and other equipment on the circuit not exceed the rating of the fuse or circuit breaker in use.

CAUTION: Be sure the power supply is of the same voltage as specified on the nameplate.

Operation

Before filling, check line switch to be sure it is in the "Off" position. Adjust the diffuser pan legs so that the pan will be at the desired depth when the water level is within 1-1/2" of top.

NOTE: Legs are not supplied on the Model 180.

Fill bath with distilled water, making allowance for displacement by the sample(s) to be immersed, and for expansion of the media upon reaching operating temperature. The maximum liquid level should be 1-1/2" from top surface of the bath after object(s) are immersed.

NOTE: Distilled water is recommended. Distilled water will not cause corrosion to the bath chamber, and cleaning of the bath will be less frequent.

-3-

Precision

 Instruction Manual

OPERATION (Contd.)

For Model 180, place the stainless steel metal tray (corners turned downward) inside the bath chamber. The tray provides a sample base and protects samples from touching the hot metal bath bottom. Fill bath with distilled water to within 3/4" of top of bath, allowing for displacement by sample(s) to be immersed, and for expansion of the media upon reaching operating temperature.

NOTE: To conserve energy and to reduce evaporation, use a cover throughout the temperature range of the bath. Do not use aluminum foil as a cover; it may cause corrosion to the stainless steel as a result of an electrolytic reaction.

Each bath is supplied with a thermometer holder (metal clip) fastened to the top of the bath and a thermometer and Oring packed separately. Slip O-ring onto thermometer, then insert thermometer through metal clip until line indicating immersion depth is at or below the water surface. When the shelf is in its highest position, the immersion line may be above the water line; however, the thermometer bulb should be located above the diffuser pan.

CAUTION: Care should be taken to protect the thermometer from accidental breakage and spillage of hazardous mercury content.

Insert line cord into the proper receptacle and turn line switch to the "On" position. This action will energize the heater and cause the red pilot lamp to turn "On" and stay lit while the heater(s) is energized. Set thermostat dial, as explained below, to obtain the desired temperature setting.

CAUTION: Exercise care when using acidic or caustic solutions, as they will attack the stainless steel bath body if spillage into the bath should occur.

Clean and remove any spillage and condensation from all sheet metal surfaces after each test. If spillage into the bath medium has occurred, the liquid should be drained and the unit thoroughly flushed.

Precision® Instruction Manual

OPERATION (Contd.)

Models 180-186

(Model 188 has a double configuration of the above.)

Setting Thermostat: A reference dial is provided to correlate thermostat setting with temperature readings taken from the mercury-in-glass thermometer.

NOTE: Reference dial numbers are for reference only and are not values for water temperature within the unit.

To determine what temperatures may be expected from various settings on the dial, select an arbitrary setting of"4" by turning the control knob in a clockwise direction. (With warmer water, a higher setting may be necessary.) With the dial set at "4" or higher, the neon-glow pilot lamp is energized. Temperature equilibrium will be indicated by a steady cycling of this lamp from "On" to "Off" approximately every minute. At this point, a temperature reading should be taken from the thermometer and noted.

It is suggested that the above procedure be repeated at progressively higher settings on the reference dial. Approach all settings in a "clockwise" direction. This means that when changing from a high setting to a lower one, the control knob should be turned back past the lower setting desired and then approached in a "clockwise" direction.

Servicing

Cleaning: To remove algae and to clean the bath, a detergent solution is recommended. Should algae or any other undesirable microorganisms form on top of the bath media, add a little formaldehyde or zephiran chloride to alleviate this problem.

WARNING: Unit must be disconnected from power source prior to servicing. It is recommended that all service be performed by qualified service personnel.

Precision® Instruction Manual

SERVICE (Contd.)

NOTE: Assembly and disassembly of these water baths for servicing will require a special tool for removal of TORX® type screws. The tool necessary is a TORX® T-25 key and maybe purchased at your local auto parts or hardware store.

General Information: To service the water bath, turn it on its side or top, remove bottom plate and insulation. To prevent scratching of the enameled surface, place protective material (cardboard, cloth, or newspaper) under unit.

Leaks: Should a leak develop, drain bath and remove shelf. Turn bath upside down and remove bottom plate and insulation. Leakage is only possible through the thermostat capillary fitting. Therefore, check locknut to see if it is tight, or if

0-ring needs to be replaced.

Thermostat Replacement: Replace thermostat if bath water does not heat and pilot light remains "off." Follow the steps below to remove the thermostat.

CAUTION: Care must be exercised when handling the thermostat capillary, since a sharp bend will crimp off the flow of the hydraulic operating medium. To avoid twisting the capillary or damaging O-ring, hold the fitting under the bath stationary, and firmly tighten locknut inside bath chamber. Do not over-tighten, as O-ring could be squeezed out of position, causing bath to leak. Under-tightening will also cause the bath to leak.

MAINTENANCE ALLOCATION CHART

Section I. INTRODUCTION

B-1

General.

a.

This section provides a general explanation of all maintenance and repair functions authorized at various maintenance categories.

b.

The Maintenance Allocation Chart (MAC) in Section II designates overall authority and responsibility for the

performance of maintenance functions on the identified end item or component The application of the maintenance functions to the end item or component will be consistent with the capacities and capabilities of the designated maintenance categories c.

Section III lists the tools and test equipment (both special tools and common tool sets) required for each main-

tenance function as referenced from Section II

d.

Section IV contains supplemental instructions and explanatory notes for a particular maintenance function.

B-2 Maintenance Functions. Maintenance functions will be limited to and defined as follows:

a.

Inspect. To determine the serviceability of an item by comparing its physical, mechanical, and/or electrical characteristics with established standards through examination (e g., by sight, sound, or feel)

b.

Test. To verify serviceability by measuring the mechanical, pneumatic, hydraulic, or electrical characteristics of an item and comparing those characteristics with prescribed standards

c.

Service. Operations required periodically to keep an item In proper operating condition, i. E., to clean (includes decontaminate, when required), to preserve, to drain, to paint, or to replenish fuel, lubricants, chemical fluids, or gases

d.

Adjust. To maintain or regulate, within prescribed limits, by bringing Into proper or exact position, or by setting the operating characteristics to specified parameters.

e.

Align. To adjust specified variable elements of an item to bring about optimum or desired performance.

f.

Calibrate. To determine and cause corrections to be made or to be adjusted on instruments or test, measuring, and diagnostic equipments used in precision measurement Consists of comparisons of two instruments, one of which is a certified standard of knob accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being compared.

g.

Remove/Install. To remove and install the same item when required to perform service or other maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair part, or module (component or assembly) in a manner to allow the proper functioning of an equipment or system.

h.

Replace. To remove an unserviceable item and install a serviceable counterpart in its place "Replace" is authorized by the MAC and is shown as the third position code of the SMR code

B-1

TM 10-6640-229-13&P

l.

Repair. The application of maintenance services, including fault location/troubleshooting, removal/installation, and disassembly/assembly procedures, and maintenance actions, to identify troubles and restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part, subassembly, module

(component or assembly), end item, or system

j.

Overhaul That maintenance effort (service/action) prescribed to restore an item to a completely serviceable/operational condition as required by maintenance standards in appropriate technical publications (i.e., DMWR)

Overhaul is normally the highest degree of maintenance performed by the Army. Overhaul does not normally return an item to like-new condition

k.

Rebuild. Consists of those services/actions necessary for the restoration of unserviceable equipment to a likenew condition in accordance with original manufacturing standards. Rebuild is the highest degree of materiel maintenance applied to Army equipment. The rebuild operation Includes the act of returning to zero those age measurements

(hours/miles, etc.) considered in classifying Army equipment/components.

Liberated Manuals -- free army and government manuals

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.

Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...

They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?

I am setting this document FREE. This document was made by the US

Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.

I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
