services or repairs on this unit.

(2) Be sure you understand the instructions

contained in this manual before attempting to service or repair this unit.

Warnings

Throughout this manual are Note, Caution, and Danger paragraphs that call attention to particular procedures. These items are used as follows:

NOTE

A note is used to amplify an operating procedure, practice or condition.

CAUTION

A CAUTION is used for an operating

procedure, practice, or condition which, if not correctly followed, could result in equipment damage.

Danger warnings are repeated here. Become

thoroughly familiar with the danger warnings and observe them at all times.

• Refer to the Operator Manual for complete instructions on operating the unit. Failure to do so could result in severe personal injury.

• Always disconnect the power cord from the outlet before removing any of the unit’s covers/panels or making any repairs to prevent the possibility of electrical shock. Failure to comply with these instructions could result in severe personal injury or death.

Warranty Instructions

Refer to the Midmark “Limited Warranty” printed on the back cover of the Installation and Operation Manual for warranty information. Failure to follow the guidelines listed below will void the warranty and/or render the Power Procedures Center unsafe for operation.

GENERAL INFORMATION

1.1 Scope of Manual

This manual contains detailed troubleshooting, scheduled maintenance, maintenance, and service instructions for the 498 Power Procedures Center unit. This manual is intended to be used by Midmark’s authorized service technicians.

1.2 How to Use Manual

A. Manual Use When Performing Scheduled Mainte-

nance.

(1) Perform inspections and services listed in

Scheduled Maintenance Chart (Refer to para 3.1).

(2) If a component is discovered to be faulty or out

of adjustment, replace or adjust component in accordance with maintenance/service instructions (Refer to para 4.1).

B. Manual Use When Unit Is Malfunctioning And

Cause Is Unknown.

(1) Perform an operational test on unit (Refer to

para 2.1).

(2) Perform troubleshooting procedures listed in

Troubleshooting Guide (Refer to para 2.2).

(3) If a component is discovered to be faulty or out

of adjustment, replace or adjust component in accordance with maintenance/service instructions (Refer to para 4.1).

C. Manual Use When Damaged Component Is Known.

(1) Replace or adjust component in accordance

with maintenance/service instructions (Refer to para 4.1).

1.3 Description Of Power Procedures Center

strong aspiration (suction) and adjustable pressure. The major components of the unit consist of a small drawer assembly, large drawer assembly, POWER ON/ STANDBY switch, VACUUM ON/OFF switch, PRESSURE ON/OFF switch, regulator, pressure gauge, front receptacle, rear receptacle, VACUUM/PRESSURE foot switch, pressure pump assembly, and a vacuum pump assembly.

B. Theory of Operation (See Figure 5-1).

Power potential is supplied to the POWER ON/ STANDBY switch and the rear receptacle when the power cord is plugged in. The rear receptacle circuit is complete at this time and is supplying either 115 VAC (domestic) or 220 VAC (export) at the receptacle outlet. If the POWER ON/STANDBY switch is switched to "STANDBY", no power potential or ground potential is being provided to the rest of the unit’s circuits. When the POWER ON/STANDBY switch is switched to "ON", power potential is supplied to the front receptacle. The front receptacle circuit is complete at this time and is supplying either 115 VAC (domestic) or 220 VAC (export) at the receptacle outlet. Also, when the POWER ON/STANDBY switch is switched to "ON", power potential is supplied to the pressure pump assembly and the vacuum pump assembly, and ground potential is supplied to the PRESSURE ON/OFF switch, the VACUUM ON/OFF switch, and the VACUUM/ PRESSURE foot switch. If the PRESSURE ON/OFF switch is switched to "ON" at this time or if the VACUUM/PRESSURE foot switch is depressed to "PRESSURE", power is applied across the pressure pump assembly, causing the pump to operate. If the VACUUM ON/OFF switch is switched to "ON" at this time or if the VACUUM/PRESSURE foot switch is depressed to "VACUUM", power is applied across the vacuum pump assembly, causing the pump to operate. The POWER ON/STANDBY switch, PRESSURE ON/ OFF switch, and VACUUM ON/OFF each have a lamp in the switch. Power potential is supplied to these lamps through separate power leads. When the switches are switched to "ON", power is applied across the lamp, causing the switch lamp to illuminate, thereby showing it is in the "ON" position.

PARTS LIST

6.1 Introduction

The illustrated parts list provides information for identifying and ordering the parts necessary to maintain the unit in peak operating condition. Refer to paragraph 1.5 for parts ordering information.

The parts list also illustrates disassembly and assembly relationships of parts.

6.2 Description of Columns

The

Item

column of the parts list gives a component its own unique number. The same number is given to the component in the parts illustration. This allows a part number of a component to be found if the technician can visually spot the part on the illustration. The technician simply finds the component in question on the illustration and notes the item number of that component. Then, he finds that item number in the parts list. The row corresponding to the item number gives the technician the part number, a description of the component, and quantity of parts per subassembly. Also, if a part number is known, the location of that component can be determined by looking for the item number of the component on the illustration.

The

Part No.

that component.

column lists the MIDMARK part number for

SECTION VI

The

Description

of the component.

The

component that is required for the subassembly. The letters “AR” denote “as required” when quantities of a particular component cannot be determined, such as: adhesive.

Bullets [ • ] in the column show the indenture level of a component. If a component does not have a bullet, it is a main component of that illustration. If a component has a bullet, it is a subcomponent of the next component listed higher in the parts list than itself that does not have a bullet. Likewise, if a component has two bullets, it is a subcomponent of the next component listed higher in the parts list than itself that has only one bullet.

6.3 Torque Specifications and Important Assembly Notes

When specific assembly torque specifications, measurements, or procedures have been identified, by our engineering department, as required to assure proper function of the unit, those torque specifications measurements, and procedures will be noted on the parts illustrations. Adherence to these requirements is essential.
