Action : Mechanical modification to the cover in front of the window may solve the problem. The problem is urgent since this is the period of the year that is most affected by condensation. We need a solution as soon as possible. Please move back the deadline! Action Log : 30 de December de 1998 12:43:50 PM gandreon Problem became urgent due to atmosferic conditions during summer. A prompt delivery is required by the TT. 7 de January de 1999 12:59:16 PM gandreon It only affect SOFI because SUSI has its own system (N2). 15 de April de 1999 5:51:49 PM weckert All parts are manufactured. During next turno the unit will be anodized and assembled and can be mounted in front of the SOFI window. 13 de May de 1999 4:29:51 PM gandreon To be installed on May 18-23. 20 de May de 1999 3:03:11 PM gandreon To be completed by June 30.

We were told that - workshop was too workloaded - the kind of boxes we always used until now at NTT are unnecessarily expensive and that it should be possible to buy some from a catalog . We therfore got a catalog from W. Eckert and after agreeing with Alain Giliotte we ordered 20 units of the model which better looked to fit our needs FOR TEST. It appears CLEARLY that these boxes are very cumbersome and even dangerous to contain filters, specially DM 8000 ones. So we still do not have a safe filter storing solution at NTT. Our ideal solution is to get maufactured manufactured anywhere 15 susi2 filter boxes ( 9 filters to arrive this year ) 5 emmi filte boxes ( spares ) 10 transparent lids ( to replace opaque emmi lids) The models we have in use now are satisfacory except opaque emmi and a little shape detail on susi2 lids. Action Log : 3 de February de 1999 2:09:13 PM gihle The time required to manufacture these boxes is : - To make the filter boxes, SUSI2 or EMMI : 3.5 hours each box plus cover. Total: 70 hours. - To make the transparent covers : 2 hours each. Total : 20 hours All material must be ordered under NTT budget. 11 de February de 1999 12:57:29 PM gandreon It will be carried out as background job. Few boxes are supposed to be delivered fairly soon. 7 de April de 1999 5:36:22 PM gihle Material for the fabrication has been ordered. We have not received it yet. 15 de April de 1999 5:53:33 PM weckert The material did not yet arrive in Chile 22 de April de 1999 3:32:03 PM weckert Material has arrived.
