1 Section RECEIVING AND INSPECTION Your satisfaction and safety require a complete understanding of this unit, including its proper function and operational characteristics. Read the instructions thoroughly and be sure that all operators are given adequate training before attempting to put the unit into service. NOTE: This equipment must be used only for its intended application; any alterations or modifications will void your warranty. 1.
2 Section GRAPHIC SYMBOLS Your incubator has been provided with a display of graphic symbols which is designed to help in identifying the use and function of the available user adjustable components. 2.1 Indicates that you should consult your manual for further description or discussion of a control or user item. 2.2 Indicates "Temperature". 2.3 Indicates "Over-temperature safety". 2.4 C Indicates "Degrees Centigrade". 2.5 Indicates "AC power ON". 2.6 Indicates "Humidifier Water Low". 2.
3 Section INSTALLATION Local city, county or other ordinances may govern the use of this equipment. If you have any questions about local requirements, please contact the appropriate local agency. Installation may be performed by the end user. It is unnecessary for this unit to be installed by a technician.
and assure all volatile or flammable cleaners are evaporated and dry before reattaching the unit to the power supply. 3.6 Humidification Water Supply: On the back of the body there is a 1/4" compression fitting marked WATER IN. This fitting should only be plumbed to a DISTILLED WATER supply source.
4 Section CONTROL OVERVIEW 4.1 4.2 4.3 4.4 4.5 4.6 4.7 4.8 4.9 Power Switch: The main power I/O (On/Off) switch controls all power to the unit, and must be in the I/On position before any systems are operational. High Limit Safety Thermostat: This control is marked SAFETY and is adjacent to the power switch. It is completely independent of the Main Temperature Controller and guards against any failure which would allow the temperature to rise past set point.
5 Section THEORY OF OPERATION These humidity chambers are designed to maintain temperature and relative humidity at set points controllable by the operator at the front panel. Air is constantly being circulated through the chamber, monitored for comparison to set points and treated if necessary. On all units, heating is done by electric resistance heaters that turn off and on for temperature control.
6 Section OPERATION It is recommended that your unit be allowed to reach operating temperature before engaging the humidifying system. This requires setting the RH set point to 0 (zero) until the unit is at operating temperature. See Section 6.6 for changing the RH set point. 6.1 Turn the power switch to the I/ON position. Turn the High Limit Safety thermostat to its maximum position, clockwise and place the shelves in the chamber. 6.
7 Section CHART RECORDER INSTALLATION Please note that the following information is a general guide for installation. Before attempting installation please read the instructions provided with your chart recorder thoroughly for specific installation instructions. NOTE: Unplug unit from the power supply before installing the Chart Recorder. 7.1 Remove cover for Chart Recorder, located on the right side of control panel. 7.2 Remove steel plate from the back of the Chart Recorder. 7.
8 Section MAINTENANCE NOTE: Prior to any maintenance or service on this unit, disconnect power cord from the power supply. Service of any electrical components should only be performed by personnel who are qualified and familiar with the use and function of these components. 8.1 Clean the chamber interior. Remove and clean shelves and shelf clips on a periodic basis using a disinfectant that is suitable to your application.
9 Section TROUBLESHOOTING Always make a visual inspection of the unit and control console when troubleshooting. Look for loose or disconnected wires which may be the source of the trouble. The incubator is designed so that no internal electrical servicing should be required under normal conditions. If electrical servicing is necessary, it should be performed by qualified service personnel. For information on where to reach technical service please see the manual cover.
1/ verify that controller is asking for heat by looking for Heating light – if pilot light is not on continuously, there is a problem with the controller 2/ check amperage – amperage should be virtually at maximum rated (data plate) amperage 3/ do all controller functions work? 4/ is the Safety Thermostat set high enough? – for diagnostics, should be turned fully CCW with the pilot light never on 5/ has the fuse/circuit breaker blown? Indicated chamber temperature unstable 1/ ±0.
1/ assure that exhaust fan is working 2/ assure that exhaust fan blower casing is free of pooled water 3/ check solid state relay 4/ set point has to be 10 percentage points below reading on control to turn exhaust fan on 5/ injection valve stuck open 6/ condensate drain tube plugged and pool of water in bottom of chamber Can't adjust set points or calibration 1/ confirm all wire connections 2/ confirm software revision 3/ call Customer Service Steam generator not working 1/ check if fill solenoid, injectio
Door not sealing 1/ adjust hinge blocks or twist the door. 2/ Confirm that unit has not been damaged and body is not square. Motor doesn't move 1/ if shaft spins freely: check connections to motor and check voltage to motor; 2/ if shaft rubs or is frozen, relieve binding and retest Motor makes noise 1) Make sure that the fan or blower wheel is not contacting its housing. Adjust the motor mounting bracket position to re-center the fan or blower wheel, if necessary.
