GENERAL USER INFORMATION

The information contained in this manual

pertains to the service procedures involved

in maintaining and servicing Maytag MFR18

through MFR80 PDC and PNC commercial

washer models built starting in the third

quarter of 2005 through 2010.

Specications and installation requirements

are included in this manual as a guide

to assist in proper performance and for

servicing the products. As with all models, the

importance of proper installation can not be

over emphasized. For additional information,

refer to the installation and programming

instructions that accompany each washer.

The MFR PDC models were introduced

in 2005 as an update to the MFR line of

commercial washers rst introduced in 1996.

This line is the third iteration of the front

loading rigid mount multiload washer line

intended for coin operated commercial laundry

usage.

The MFRxxPNC line offers similar models

intended for non-coin on premise laundry

purposes.

Currently the washers are offered in capacities

ranging from 18 pounds to 80 pounds of

regular water-washable laundry (clothing and

linens).

All MFRxxPNC models use microprocessor

controls for maximum versatility in

programming and service diagnosis.

All models use variable frequency drive motor

controls for optimum wash and extraction

speed settings.

The US model number indicates the Brand,

drive type, mounting method, capacity, and

control type.

M = Maytag product.

F = Front loading washer

R = Commercial Rigid mount washer

MFR washers have a rigid frame and depend

on a proper installation on a solid foundation

to absorb and dissipate out-of-balance

stresses and vibration.

The capacity designation follows next in the

model number layout to indicate capacity

in pounds for the maximum load size in dry

weight (before washing).

18 = eighteen (18) pounds capacity

25 = twenty ve (25) pounds capacity

30 = thirty (30) pounds capacity

40 = forty (40) pounds capacity

50 = fty (50) pounds capacity

60 = sixty (60) pounds capacity

80 = eighty (80) pounds capacity

Next is the type of controls used. All will begin

with the letter “P” to indicate microprocessor

based controls.

MFRxxPDC indicates a microprocessor

control with a coin drop money acceptor. The

“D” indicates coin drop equipped. The “C”

indicates the model change (A, B, D, C) since

introduction. The coin drops supplied will

either be from Munzprufer or from Greenwald

Industries. The standard drop is for a single

US or Canadian Quarter (the Canadian drop

will have to have the anti-cheat magnet

removed). Accessory drops that accept more

than the quarter are available as after-market

assemblies.
