3.Remove the reaction cell assembly.
4.Remove the two connectors on the PMT housing end plate facing towards the front panel.
5.Remove the end plate itself (4 screws with plastic washers). R
6.Remove all of the desiccant bags inside the PMT housing.
7.Along with the plate, slide out the OPTIC TEST LED and the thermistor that measures the PMT temperature.
•The thermistor will be coated with a white, thermal conducting paste. Do not contaminate the inside of the housing or the PMT tube with this grease.
8.Unscrew the PMT assembly. It is held to the cold block by two plastic screws.
•Because the threads of the plastic screws are easily damaged it is highly recommended to use new screws when reassembling the unit.
9.Carefully take out the assembly consisting of the HVPS, the gasket and the PMT.
10.Change the PMT or the HVPS or both, clean the PMT glass tube with a clean, anti-static wipe and do not touch it after cleaning.
11.If the cold block or TEC is to be changed disconnect the TEC driver board from the preamplifier board.
a.Remove the cooler fan duct (4 screws on its side) including the driver board.
b.Disconnect the driver board from the TEC and set the sub-assembly aside.
c.Remove the end plate with the cooling fins (4 screws) and slide out the PMT cold block assembly, which contains the TEC.
d.Unscrew the TEC from the cooling fins and the cold block and replace it with a new unit.
12.Re-assemble the TEC subassembly in reverse order.
CAUTION
The thermo-electric cooler needs to be mounted flat to the heat sink. If there is any significant gap, the TEC might burn out. Make sure to apply heat sink paste before mounting it and tighten the screws evenly and cross-wise.
a.Make sure to use thermal grease between the TEC and the cooling fins as well as between the TEC and the cold block.
b.Align the side opening in the cold block with the hole in the PMT housing where the sample Chamber attaches.
c.Evenly tighten the long mounting screws for good thermal conductivity.
13.Re-insert the TEC subassembly. Make sure that the O-ring is placed properly and the assembly is tightened evenly.
14.Insert the LED and thermistor into the cold bloc.
