the autoclave!

1.1 Incoming Inspection

Upon receiving your Tuttnauer Autoclave, carefully inspect the outside of

the shipping carton for signs of damage. If any damage to the carton is

found, note the location with respect to the autoclave and check that area

of the autoclave carefully once it is fully unpacked. Observe packing

method and retain packing materials until the unit has been inspected.

Mechanical inspection involves checking for signs of physical damage

such as: scratched panel surfaces, broken knobs, etc.

If any damage is found, contact your dealer as soon as possible so that

theycanfile a claimwith the shipping carrier and also notify Tuttnauer.

All Tuttnauer products are carefully inspected prior to shipment, and all

reasonable precautions are taken in preparing them for shipment, to assure

We certify that this instrument is guaranteed to be free from defects in

material and workmanship for two years against faulty components and

assembly.

This warranty does not include routine cleaning and preventive

maintenance to be performed according to instructions in

section 9.1 (Preventive and Scheduled Maintenance).

Tuttnauer warrantees all new autoclaves for a period of two full years,

covering both parts and labor. This two year warranty covers defects in

materials and workmanship on every part in the autoclave except door

gaskets and HEPA filters (they are wear items).

Tuttnauer warrantees all chambers for a period of ten (10) years against

defects in materials and workmanship. This chamber warranty went into

effect January 1997.

This warranty does not apply to any instrument that has been subjected to

misuse, neglect, accident or improper installation or application, nor shall

it extend to autoclaves that have been repaired or altered outside the

2 TECHNICAL DATA

2.1 Introduction

This tabletop autoclave is designed for the sterilization of wrapped and

unwrapped instruments and related items found in dental, medical and

veterinary clinics, first aid rooms, hospitals, laboratories, etc.

This autoclave is an electrically heated sterilizer using steam as the

sterilizing agent. A computerized control unit ensuring a fully automatic

sterilization cycle, control and monitoring of physical parameters and a

clear documentation of the sterilization cycle controls the autoclave.

The autoclave has three automatic programs, according to the material to

be sterilized, and one auxiliary drying program. Models EA and EKA are

equipped with an air compressor that, during the drying stage, draws air

through a HEPA filter (0.2µm). It pushes that air through the heated

chamber to remove moisture and facilitate the drying operation. Drying is

performed with the door closed.

On all models (except 1730), a water pump is installed between the water

reservoir and the chamber. This pump guarantees fast and accurate filling

of the chamber every time. Entry of water may be accompanied by a

noise for approximately 30 seconds. This is normal noise generated by

regular operation of the pump.

The control system provides adequate protection to ensure the safety of

personnel and reliable operation with a minimum of shutdown time.

On all models (except 1730), a printer is an optional addition to the

autoclave. The printer prints the preset and actual parameters of the cycle

(temperature, time and pressure).

This manual is intended for the user and gives the user a general

understanding of the instrument and the best ways to operate and take

care of it in order to obtain optimum effective results.

After reading this manual, operating the autoclave will be easy. However,

since this instrument is built with high technology sensitive components,

no attempt should be made by the user or any other unauthorized person

to repair or recalibrate it.

Only technical personnel, having proper qualifications and holding

technical documentation (including a technician manual) and

adequate information are authorized to service the apparatus.

2.2 Standby Heating Mode

The autoclave provides an option of heating the chamber in standby

mode between cycles with a very low power in order to reduce total cycle

time (1.6% of the total power only). The autoclave turns off automatically

if the interval between the sterilization cycles is more than 2 hours. This

feature is standard on all EK, EKA models and optional on all E, EA

models.

2.3 Environmental Emission Information

1. The peak sound level generated by the autoclave is less than 70 dBA

with background noise of 60 dBA.

2. The total heat per hour transmitted by the autoclave is < 100 Wh for all

models.

2.4 Operating Conditions

This device is to be used for indoor use.

This autoclave is intended for NORMAL environment conditions as

follows:

Altitude up to 2000m.

Room temperature range 41ºF to 104ºF (5ºC to 40ºC).

Installation Category II.

Pollution Degree 2.

Maximum relative humidity 80% for temperature up to 31ºC decreasing

linearly to 50% relative humidity at 40ºC.

Main supplyvoltage fluctuations up to +/-5% of the nominal voltage.

The sterilizer should be loaded only with autoclavable material.

Caution!

Waste water should be brought into the public net in accordance

with the local rules or requirements, i.e.

ONLY NON-HAZARDOUS LIQUIDS SHALL BE DISPOSED IN

PUBLIC SEWAGE!
