Comments:
D1's Contactor is very loud. All the screws were tightened but did not seem to help. The model number was recorded and filed in case a new one is needed.

Comments:
Troy 16:08, 9 February 2009 (UTC) All systems appear to be in good working condition. There seems to be an increase in vibration on the fan for DH-1. This will need to be monitored more closely in the future.
Troy 10:28, 23 April 2009 (PDT) Still a good vibration on the fan for DH-1.
--Troy 13:00, 19 October 2009 (PDT) I was able to reduce the vibration by pushing the sides together while tightening the lid.
Troy 09:32, 24 December 2009 (PST) On 11/04/2009 it was discovered that D1 was failed, (it failed ~10/25/2009). Replacement parts were ordered and the unit was put back into commission on 12/23/2009. The Gear-motor and Process Fan were replaced. The unit had ~15580 hours of run time on it.

Comments:
--Troy 15:30, 14 January 2010 (PST)There is almost a 1% difference between RH1's relative humidity reading RH2's. D1 is running very quite, no vibration with new fan.
--Troy 09:08, 18 May 2010 (PDT) D2 vibrations seem to have increased. D1 has been very quiet since the fan was replaced. D1's desiccant wheel is getting brittle in places and a small section has broken off.
--Troy 09:41, 23 June 2010 (PDT) On 06/21/2009 it was discovered that D2 had failed, (it failed 21/06/2010 06:51:00). The Process Fan was replaced. The unit had ~18182 hours of run time on it prior to the fan failing.
Troy 11:09, 20 July 2010 (PDT)Both units are running very well, very quiet since the fan replacements.
--Troy 08:35, 28 October 2010 (PDT) Both units are running very well, very quiet.

Comments:
Troy 08:28, 18 January 2011 (PST) Both units are running quiet, no vibration issues, the belt on D1 was showing a little fraying on one side, not enough to warrant replacement.
Troy 09:54, 29 April 2011 (PDT)Both units are running well and the RH control seems to be working well. The contactor for D1's heater continues to have a hum.
--Troy 09:01, 10 November 2011 (PST) Curious as to why the current draw is lower...?

Comments:
Troy 11:13, 22 February 2012 (PST) The Panel meter was 2 amps greater than the amperage read by the amp probe and could not be adjusted.
Troy 12:57, 26 April 2012 (PDT) New Amp probe used, panel meter adjusted to match new amp probe. Units are running quiet. (Roger Clark performed Check)
