1 General
The ovens with electric heating are designed for laboratories, generally for a warming of various materials by means of hot air at adjustable temperature and optional time. The air flap enables drying of wet material.
A modern microprocessor (Fuzzy - logic) with a digital display and PT 100 controls the temperature. Thus exact temperature accuracy and process safety are guaranteed.
The ovens are designed according to EN standards.
They are manufactured of high grade materials with the latest technology. Each oven is subjected to a strict final test leaving the plant.
1.1Purpose and Use
VENTICELL (VC) serves for warming of materials by means of hot air with forced-air circulation by a fan. The ovens are designed for temperatures up to 250 °C, another variant
(+) up to 300 °C.
INCUCELL (IC, ICV) serves as an incubator or for cell cultivation in a microbiological laboratory (see chapter Optional equipment, article Adaptation against drying-up of cultivating mediums and tissue cultures). The ovens are designed for temperatures up to 70 °C. A quiet operation is characteristic for the variant IC (without a ventilator), more accurate temperature regulation with small deviations is characteristic for the variant ICV (with ventilator).
ECOCELL (EC) serves for warming by hot air with natural circulation. The ovens are designed for temperatures up to 250 °C. They work quietly with lower power consumption compared with VC units.
STERICELL (SC) serves for sterilizing by hot air with forced-air circulation by a fan. The ovens are designed for temperatures up to 250 °C. STERICELL uses time-delayed switchoff program for sterilizing, refer to section Set and Running the Sterilizing Program.
DUROCELL (DC) serves for warming by hot air with natural circulation (usefull at procedures as acid hydrolysis, extraction by nonflammable solvents, thermolysis). The ovens are designed for temperatures up to 125 °C. Internal surface is covered by a layer of EPOLON, that protects the chamber against corrosive influence of acids in the form of vapors or liquids.
2 Important Instructions
2.1Unpacking, checking and transport
Please check after unpacking the oven and its accessories are complete and not damaged. A possible damage is to be reported to the forwarding agent. An eventual damage must be immediately reported to the transporting company.

During the manipulation – in case of lifting the cabinet etc. – the cabinet cannot be hold by the rail or door. The cabinets of volumes 404 and 707 should be lifted by means of delivered hooks, the rolls are designed for local moving, not for longer transport.
The standard delivery consists of the temperature cabinet, two sieves.
2.2Pre-installation
♦Please read carefully the operating instructions before working with the oven!
♦Install the instrument by plugging the power cord to a line voltage socket. The specified parameters of the connection are described in chapter Electrical Connection. Adjust the position of air valve according to chapter Air Valve - Adjustment and Functions. For VC, SC and ICV types, adjust two air valves – suction and exhaust.
After the first switching-on of the unit the heating bodies and insulation start to be baked with a typical a smell; after a few operation cycles this smell disappears, nevertheless it is suitable, during the insulation baking at a temperature above 100°C, to secure a sufficient air exchange (e.g. by ventilation or exhaustion).
At temperatures above 100 °C the inner chamber surface becomes yellowish. This coloration is neither the material nor the device defect.
The air exhaust in VC, EC a SC types is protected by a cover rear of the unit. This cover is placed inside the oven while shipping. When installing the unit, insert the cover into the horizontal openings bellow and above the exhaust to attach it behind the exhaust.
An air filter can be connected to the suction hole in SC types - see section
Function and filtration characteristics of the air filter.
Ovens are designed to be operated indoor within ambient temperatures from 5 °C to 40 °C and at maximum relative humidity 80 %.
The oven should be installed with a 100 mm distance to the walls at the side and in back. The temperature of the air coming out of the exhaust may be up to 250 °C
(resp. 300 °C), so the walls near the oven must be inflammable
.
No inflammable or explodable materials may be put into ovens !
Carrying capacity of the floor during installation of the device must correspond to the weight of the unit itself taking the weight of the maximum charge into consideration (see chapter Parameters of the unit).
The unit must not be placed on a pad that could cause a danger of fire or smothering in case of falling some hot object out of the cabinet.
No inflammable, explosive or toxic materials may be put into ovens! The same applies to materials that could give off such a stuff.
Goods are only to be put on trays into ovens, never directly on the bottom of the oven! No dangerous goods are permitted. Ovens may not be used for heating of liquids.

Aparatus may not be used in the atmosphere with a possible danger of flammable or explosive anesthetics.
Any assembling or disassembling may be done only when disconnected from mains! After the button (button 11, fig. 4) activates the stand-by state, the oven comes only to a stand-by state, however it is not disconnected from the mains!
♦If the oven is not used for a longer time, disconnect it from mains by pulling the service cord from the socket
Power cord can not get to the contact with hot parts of the aparatus – protection cover of exhaust hole
♦Safety thermostat assures the protection of the oven, surroundings and goods against surpassing the rated temperature. Protection through temperature safety class 2 according to EN 61010-2-010 is for VC and EC, protection through temperature safety class 3 according EN 61010-2-010 cs for IC, ICV. Check regularly – daily – the function safety thermostat.
♦The door and the exhaust air flap in SC type are provided with microswitches - see section Setting and running the sterilizing program.
Pull out and consequently push in the upper metal plate piece of internal chamber carefully, there is a danger of cutting through the rubber gasket of the chamber during careless manipulation.
The maximum permitted loads: see section Parameters of the unit.
Only for STERICELL
The units of STERICELL 404 are provided with a door lock – for securing the safety. You can enter the chamber, e.g. because of cleaning, only if the door is locked (blocked) in an open state. You must keep the key all the time you find yourself inside the chamber.
When operating the cabinets at high chamber temperature there can be the maximum allowed temperature of 70 °C at their outer surface (exhaust ports and their surroundings and the surroundings of the chamber sealing, window and door surface in case of the optional type with window in door) surpassed and there is a danger of burns. Please take a high precaution.
During the operation of the devices of 404 and 707 at high temperatures a deformation of the inner door surface occurs as a consequence of thermal tension, which makes their closing more difficult. If you open the door in this state, do not close them until the chamber is cooled down. Otherwise the door mechanism could be damaged.

2.3Useful space
Useful space is illustrated on fig. No. 1, where X(H) = 10 % of the inner chamber depth, X(Š) = 10 % of the inner chamber width, X(V)1 is the distance from the lowest tray to the bottom of the inner chamber, X(V)2 is the distance from the upper most tray to the ceiling of the inner chamber. The required temperature accuracy - see section Parameters of the unit - is achieved only in the space defined above (according to DIN 12 880 - marked with thick lines, thin lines mark inner chamber walls). It means, that over the last upper tray there are the limits from section 5. not obligatory.
For Stericell following definition of the sterilizing space is valid:
at the side to the door is X(D) = 20 % of the inner chamber depth, at the rear side in the single-door type X(D) = 10 % of the inner chamber depth, X(W) = 10 % of the inner chamber width, X(H)1 is the distance from the lowest tray to the bottom of the inner chamber, X(H)2 is the distance from the upper most tray to the ceiling of the inner chamber. The required temperature accuracy - see section Parameters of the unit - is achieved only in the space defined above (according to DIN 12 880 - marked with thick lines, thin lines mark inner chamber walls). It means, that over the last upper tray there are the limits from section 5. not obligatory.
