Cleaning and Maintenance

Return To Table Of Contents

After installation has been completed, thoroughly clean the chair and upholstery.

After the initial cleaning, it should be cleaned as necessary and at least weekly.

Observe the following instructions.

A NOTE ABOUT THE UPHOLSTERY: All Knight Chair upholstery is made from the highest

quality materials available and is designed for maximum patient comfort, easy cleaning

and durability. Knight Chair upholstery will provide years of service when correctly

maintained according to the Operator and Care Manual. Like all fine upholstery some

minor wrinkles, waves or changes may occur. These changes are natural and in no way affect the

performance or life of the product.

CLEANING THE

UPHOLSTERY

When cleaning upholstery, it is

suggested that you use all

recommended commercial

cleaning agents in an

inconspicuous spot to check

for potential damage to the

upholstery material before

applying to the entire area to

be cleaned. For everyday

cleaning, we recommend a

mild dish washing liquid, warm

water, and a damp white

cloth. Spraying upholstery with

a silicone-based coating will

improve luster and soil

resistance.

CLEANING PAINTED

SURFACES

The painted metal surfaces are

covered in durable, powder-

coated paint which is resistant

to scratching and scuffing. It

may be cleaned with a clean

cloth dampened with mild,

soapy water. To add luster and

dirt resistance, use a pre-

softened car wax.

RECOMMENDED

INFECTION CONTROL

PRODUCTS

The disinfectant/cleaner

products that we have tested

and recommend for our

upholstery, painted items and

plastic covers are as follows:

Cavicide

distributed by E&D Dental

Products Inc., Westfield, NJ

Precise - Hospital Foam

Cleaner Disinfectant

manufactured by Caltech

Industries, Inc., Midland, MI

CAUTION: Follow

manufacturer's

directions for

concentration and

application of disinfecting

material. Avoid prolonged

application of any disinfectant/

cleaner products, because

they may cause staining of

upholstery material.

TROUBLESHOOTING

Only in case of no power to the

chair should dental personnel

attempt to remedy the

problem. In this case, (1) make

sure that the power cord is

firmly plugged into the

receptacle or (2) check that

the main circuit breaker to the

chair is turned on.

CAUTION: All

troubleshooting and

maintenance on the

chair should be

performed by a qualified

technician. Dental personnel

must not attempt to perform

any maintenance functions on

the chair, attempt to replace

any fuses or other electronic

components, or attempt to

gain access to the motors or

other units.

LUBRICATION

After extended use your chair

may require lubrication at pivot

joints (i.e. chair back pivot

joint). Lubricate the joints with

a drop of light weight oil or

silicone lubricant.
