1.6 USING A CUSTOMER-SUPPLIED HEAT SINK
This is a special case. Standard detectors are calibrated and shipped complete with a Gentec-EO
heatsink or back module installed. However, should the customer wish to install an alternative
heatsink or back module, the following indications should be followed. This does not apply to the
XLP, UP_P, UP_T, UP_M, and UP_G series.
Instructions :
1. Required specifications for customer-supplied back module are given in Fig 1-10 through 1-
12. Note that tapped holes must be electrically conductive, and that there has to be at least
bare spots to allows electrical contact with detector (see point 5.).
2. While keeping together the front cover and the central housing, remove the four front
screws of the UP detector.
3. Discard the back module.
4. Apply electrically-conductive silver epoxy on the bare contact zones of the back module
(Tra-Con, Tra-Duct no. BA-2902). This will ensure proper electrical contact between the
new back module and the central housing.
5. Apply thermal paste (such as Wakefield Engineering Inc. thermal paste part no. 120-2) on
the remainder of back module. This will ensure proper thermal contact with the new back
module.
6. In the case that both central housing and back module are entirely bare and electrically
conducting, a grease that is both thermally and electrically conductive (Timtronics Black Ice
712) may be applied, instead of steps 4. and 5.
7. Install the new back module onto the detector using the the four original screws. It is
strongly advised to apply removable thread locker (Loctite removable thread locker 242) on
the screws before inserting them. The recommended torque for each of the 4 screws is 6
in.lbs. (70 Ncm).
