Safety regulations

1.2Product safety and dangers

The appliances described in this manual are technically sophisticated, manufactured using high-quality materials and subject to many hours of testing in the factory. They contain the latest technology and comply with recognised technical safety regulations. However, there are still risks involved, even when the appliances are used as intended. These are described below.

Warning!

After removing covers, live parts may be exposed. You may receive an electric shock if you touch these parts. Disconnect the mains plug before removing any covers. Only electrical technicians may work on the electrical equipment of the appliances.

Warning!

When loading the appliance with an unsuitable load, poisonous or explosive vapours or gases may be produced. This could cause the appliance to explode, and persons could be severely injured or poisoned. The appliance may only be loaded with materials/test objects which do not form any toxic or explosive vapours when heated up (see also "Intended use" on page 8).

Warning!

Depending on operation, the surfaces in the working chamber and the chamber load may still be very hot after the appliance is switched off. Touching these surfaces can cause burns. Wear heatresistant protective gloves or wait until the appliance cools down. To do so, pull the handle bar until the door springs open into its ventilating position (see page 21).

Warning!

In case of appliances of a certain size, you can get accidentally locked in, which is life-threatening. Do not climb into the appliance!

1.3Requirements of the operating personnel

The appliance may only be operated and maintained by persons who are of legal age and have been instructed accordingly. Personnel who are to be trained, instructed or who are undergoing general training may only work with the appliance under the continuous supervision of an experienced person.

Repairs may only be performed by qualified electricians. The regulations in the separate service manual must be observed.

Safety regulations

1.4Responsibility of the owner

The owner of the appliance

is responsible for the flawless condition of the appliance and for its proper operation in accordance with its intended use (see page 8);

is responsible for ensuring that persons who are to operate or service the appliance are qualified to do this, have been instructed accordingly and are familiar with the operating instructions at hand;

must know about the applicable guidelines, requirements and operational safety regulations, and train staff accordingly;

is responsible for ensuring that unauthorised persons have no access to the appliance;

is responsible for ensuring that the maintenance plan is adhered to and that maintenance work is carried out properly (see page 43);

has to ensure that the appliance and its surroundings are kept clean and tidy, for example through corresponding instructions and inspections;

is responsible for ensuring that personal protective clothing is worn by operating personnel, e.g. work clothes, safety shoes and protective gloves.

1.5Intended use

This appliance is exclusively intended for heating up non-explosive substances and objects.

Any other use is improper, and may result in hazards and damage.

The appliance is not explosion-proof (does not comply with the German workplace health & safety regulation VBG 24). The appliance may only be loaded with materials and substances which cannot form any toxic or explosive vapours at the set temperature and which cannot explode, burst or ignite.

The appliance may not be used for drying, vaporising and branding paints or similar materials the solvents of which could form an explosive mixture when combined with air. If there is any doubt as to the composition of materials, they must not be loaded into the appliance. Potentially explosive gas-air mixtures must not form, neither in the working chamber nor in the direct vicinity of the appliance.

Steriliser SF

The appliance’s intended use is the sterilisation of medical material through dry heated air at atmospheric pressure (also see page 42).

Appliances IF/UF for use as medical device

For appliances IF and UF with extended overtemperature protection (option A6, recognisable due to standard DIN 12880-2007-Kl.:3.1 on the nameplate) subject to the 93/42/EEC directive (Directive of the council on harmonisation of the laws of the member states relating to medical devices), the intended use is defined as follows: The appliance’s intended use is the warming of non-sterile cloths and covers.

Safety regulations

1.6Changes and alterations

No unauthorised changes or alterations may be made to the appliance. No parts may be added or inserted which have not been approved by the manufacturer.

Unauthorised modifications or changes result in the CE declaration of conformity losing its validity and the appliance must no longer be operated.

The manufacturer is not liable for any damage, danger or injuries that result from unauthorised changes or alterations, or from non-observance of the regulations in this manual.

1.7Behaviour in case of malfunctions and irregularities

The appliance may only be used in a flawless condition. If you as the operator notice irregularities, malfunctions or damage, immediately take the appliance out of service and inform your superior.

You can find information on correcting malfunctions from page 29.

1.8Switching off the appliance in an emergency

Push the On/Off switch on the control panel (Fig. 1) and disconnect power plug. This disconnects the appliance from the power supply at all poles.

Warning!

Depending on the operation performed , the surfaces

in the working chamber and the chamber load may still be very hot after the appliance is switched off. Touching these surfaces can cause burns. Wear heatresistant protective gloves or wait until the appliance cools down. To do so, pull the handle bar until the door springs open into its ventilating position (see page 21).

Setup and description

2.2Function

Appliances of the UN, SN and IN type series feature

natural circulation

(convection). For the UF, SF and IF type series, air is circulated by a fan at the working chamber rear panel

Fig. 3, No. 1). It increases the air flow and provides stronger horizontal forced air circulation than natural convection.

In both the convection and fan ventilated appliances, supply air (2) is preheated in a pre-heating chamber

(3). Through the ventilation slits in the side panel of the working chamber, the preheated air is introduced into the interior of the chamber. The supply and exhaust air (5) volume (air change) is controlled by the

air flap (4) on the rear panel of the appliance.

2.3Material

For the outer housing, MEMMERT deploys stainless steel (Mat.No. 1.4016 – ASTM 430) and for the interior, stainless steel (Mat.No. 1.4301 – ASTM 304) is used, which stands out through its high stability, optimal hygienic properties and corrosion-resistance towards many (but not all!) chemical compounds (caution for example with chlorine compounds).

The chamber load for the appliance must be carefully checked for chemical compatibility with the materials mentioned. A material resistance table can be requested from the manufacturer.

2.4Electrical equipment

Operating voltage and current consumption: See nameplate

Protection class I, i.e. operating insulation with PE conductor in accordance with EN 61010

Setup and description

2.5Connections and interfaces

2.5.1 Electrical connection

This appliance is intended for operation on an electrical power system with a system impedance Z ax of a maximum of 0.292 ohm at the point of transfer (service line). The operator must ensure that the appliance is operated only on an electrical power system that meets these requirements. If necessary, you can ask your local energy supply company what the system impedance is.

Observe the country-specific regulations when connecting (e.g. in Germany DIN VDE 0100 with residual current circuit breaker).

2.5.2 Communication interface

The Ethernet interface is intended for appliances which meet the requirements of IEC 60950-1.

Via Ethernet interface, the appliance can be connected to a network to read out protocol logs with AtmoCONTROL, the optional appliance software. The Ethernet interface is located on the rear of the appliance (Fig. 4).

For identification purposes, each appliance connected must have its own unique IP address. Setting the IP address is described on page 33

	With an optional USB to Ethernet converter,	Fig. 4	Ethernet interface
	the appliance can be directly connected to a
	computer / laptop (see "Optional accessories"
	on page 15).

2.6 Designation (nameplate)

The nameplate (Fig. 5) provides information about the appliance model, manufacturer and technical data. It is attached to the front of the appliance, on the right side under the door (see page 10).
