Introduction Symbols 1.2.1 Symbols used in this manual Warning. Information or instructions that are related to safety. Failure to follow these instructions may result in personal or third-party injury. Caution. Important information or instructions related to the safe use of the equipment.
Introduction 1.3.1 First aid IF IN DOUBT, SEEK IMMEDIATE MEDICAL ATTENTION. If any quantity of liquid nitrogen comes into contact with the skin or eyes, immediately flush that area of skin with large quantities of tepid water. Do not use strong flows of water as this could cause tissue damage. Continue to flush the area and seek medical attention.
Introduction Cautions The connectors on the equipment must only be used for connection to other equipment described in this document. When heating under manual control, check the chamber temperature at intervals of 30 seconds or less to avoid overheating. User servicing is limited to cleaning and decontamination. All other servicing must only be undertaken by suitably trained engineers.
Introduction Stand clear of boiling and splashing liquid nitrogen and its gas when filling a dewar or when inserting objects, such as a pump, into the liquid. Use tongs or wear suitable protective gloves when handling cold or hot objects. Never remove a pump from a dewar until the pressure gauge reading has fallen to zero.
Introduction 1. Controller: measures the current temperature and adjusts the amount of liquid nitrogen or heat that is supplied to the chamber. 2. Chamber: contains the samples being cooled and houses the heater and liquid nitrogen injection components. The chamber temperature is controlled by injecting liquid nitrogen into the chamber and by switching on an internal heater.
Introduction 1.6.3 MR7 controller 1.6.3.1 Guide to the MR7 controller The equipment is designed to cool samples by following a predefined time-temperature profile. The temperature-time relationship is referred to as the profile. The equipment comprises two main elements: 1. <%MR7_CONTROLLER%>: the user interface and temperature controller. This comprises two internal subsystems: IO Control Board: measures the current temperature and adjusts the amount of...

Installing the liquid nitrogen supply Warning Installation must only be undertaken by suitably trained personnel. Your service provider will connect the chamber to a liquid nitrogen cylinder or a Planer pump and dewar. Series 370-M & 570-M: Instructions for use MA201231-M-EN 1.0.1...
Operating the equipment Using a Planer pump and dewar For instructions on how to use the Planer LNP4 pump and dewar see MA007422, LNP4- FS instructions for use. Configuring the controller For details of how to configure the MR7 controller see MA200524, MR7 Instructions for use.
2.4.2 Preparing the nitrogen supply Caution Ensure that you have enough liquid nitrogen to complete your freezing run. If using a Planer pump and dewar, follow the instructions in Using a Planer pump and dewar If using a cylinder, refer to the manufacturer's instructions on how to switch on the supply.
Operating the equipment Fig.1 Log in screen 3. Select how you want to run the profile: a. If you intend to run the profile using DeltaT, select Control from PC and then refer to the DeltaT documentation. b. If running directly from the controller, select profile.
Operating the equipment 2. After loading the samples, wait five minutes to allow the chamber to re-stabilise. 3. Then press on the controller to start the run. 4. The profile will now run. 5. At the end of the run, the controller will prompt you when the samples are ready for removal.
Operating the equipment Switching off the system CAUTION Switching off the chamber at sub-zero temperatures may cause serious damage to the equipment. If connected to a liquid nitrogen cylinder, allow the hose to thaw and warm up to room temperature before shutting off the valve on the cylinder. 1.

Routine maintenance and troubleshooting...
Routine maintenance and troubleshooting Routine maintenance and troubleshooting Routine maintenance Warning Before cleaning: o Switch off the equipment. o Disconnect the mains supply at the wall socket. o Turn off any connected liquid nitrogen cylinders. o Open the red pressure relief valve on the pump. Wait until the pressure on the gauge has fallen to zero and the flow of gas has stopped.
Routine maintenance and troubleshooting Warning The equipment is classified as Class I equipment and must be earthed for safe operation. Repetition of potentially damaging high-voltage flash tests should be avoided. To ensure adequate earth bonding, the equipment and mains cables must be regularly checked by suitably trained personnel using a Portable Appliance Tester or similar equipment.
Check the nitrogen supply. Check the fuses. If using a Planer pump, check that the pump filter is not blocked by ice. 3.3.4 The chamber will not heat Warning Refer to the safety instructions at the front of this manual.
3.3.6 Returning for service Should the equipment or any part of the equipment need to be sent back to Planer Limited for repair, or if the equipment is to be inspected, maintained or repaired on-site by Planer Limited personnel, a Decontamination Certificate must be completed.
