General Recommendations

3.1

Intended Use Helmer platelet incubators are intended to provide the controlled temperature environment required for the storage of platelet products. The devices are intended to be operated by personnel who have procedures in place for meeting FDA, AABB, EU or any other applicable regulations for the processing and storage of platelet products.

3.2

General Use Allow platelet incubator to come to room temperature before switching power on. During initial startup, motion alarm may sound if the motion is disabled, and low temperature alarm may sound while platelet incubator reaches operating temperature.

3.3

Initial Loading After platelet incubator reaches room temperature, allow chamber temperature to stabilize at the setpoint before storing product.

Operation

8.1

Initial Start Up 1 Plug the power cord into a grounded outlet that meets the electrical requirements on the product specification label. 2 Switch the AC ON/OFF switch ON. 3 Connect the backup batteries for the monitoring system and alarms. 4 Connect the backup battery for the temperature chart recorder. 5 Install the alarm check tube (PC100i). Position the tube below the probe tip. 6 Select the display language. ► When the platelet incubator is powered on, the System Options is displayed. ► Press the INC or DEC buttons to select the language. ► Press the HOME button. 7 Press the MUTE button if the Low Temperature alarm sounds. NOTE

8.2

► When the door switch is bypassed, the incubator and door open alarm continue to operate as if the door is closed. ► The door switch controls power to the built-in agitator on PC4200i platelet incubator, and controls power to the internal outlets on all other models. ► The door switch may be bypassed by opening the door and pulling the switch cylinder.

Configure a Platelet Agitator for Use in an i.Series Incubator (Optional) Helmer i.Series platelet agitators may be installed in a stand-alone configuration, or in Helmer i.Series platelet incubators. ► Motion data is transmitted from the platelet agitator, through the data cable, to the platelet incubator. ► The platelet incubator interprets the motion data and generates its own motion alarm, based on its own alarm delay period. ► If the motion alarm is not disabled on the platelet agitator, the motion alarms on both devices will sound. NOTE

360093-1/P

► Disable the platelet agitator motion alarm when installing the platelet agitator in a Helmer i.Series platelet incubator. ► Refer to the platelet agitator service manual for information regarding the installation of a platelet agitator in a platelet incubator.
