Dear Bob:

This letter will summarize our conversation of Tuesday, 22 November 1983 on the air
conditioning units on the referenced project.

Over the past several weeks I was finally able to discuss this problem with both Carroll
Air Systems, representatives of the unit manufacturer, and Fred Keene, installing
contractor. I requested Carroll Air send me the installation and service manual since
you indicated that you never received one. In going through this manual I am sorry to
see that the preventative maintenance method of back flushing the condenser is not
mentioned. This method, that I discussed with you, however is highly recommended by
Carroll Air and I agree with them.

I am enclosing copies of the manual for your use as well as a sketch that you should
give to the service mechanic that is going to work on your units so we will end up with
proper valving to permit reverse flushing and cleaning of your condenser.

As we discussed, the condensers should be in good shape provided they are thoroughly
flushed with the proper cleaning solution for the fouling material that is present. I am
not going to tell your mechanic what to use because if he is good he will know. He
should also check the flow of water the unit is receiving. A lack of adequate flow can
be detrimental to the unit.

The preventative maintenance we discussed would require a check after six months of
operation to see how much build-up occurs in the condenser in that period of time. At
that point the mechanic could tell you whether a flushing is required every six months
or every year. Although you apparently have bad quality water I feel every year should
be adequate, but have it evaluated in six months.

As I mentioned, your compressors are under warranty and will be replaced by the
manufacturer without cost to you. All labor cost, however, will be at your expense.
Make sure you get new 5-year warranties on your new compressors.

I have checked the shop drawings to see what safety controls are available and which
ones you have. On these units no complete lockout controls with the exception of the
short cycling type is available. Your units have this control. This should lock out your
unit if it tries to keep restarting. Have the service mechanic check to see if this
control is functioning. It is designed to keep your compressor from killing itself trying
to keep starting when it shouldn't.

If we can provide additional information, please call us.

Very truly yours,
