Air Handler Unit Installation
Air Handler Unit Installation
(OP)
Our hospital is installing a new Air Handler unit and duct work in our attic. I've asked the project coordinator for the hospital, the installer and the A/E what are the points of Risk and what are the key quality control issues we should keep an eye on during the install to ensure the job be done well and problem free. I've gotten no answers.
Why does it seem like I'm barking up the wrong tree with the questions. I'm thinking if this group can't answer the question there's nobody driving the bus??

You could, ask that the Test and Balance be done by owner..or if that is too late..simply ask if the Test and Balance people will keep you updated on the performance of the HVAC system, and provide you with the final report..if you are in a position of responsibility for the project that is.(you did'nt say).

I can offer these tips to help prevent the transmission of vibration. You want to resiliently mount the suspended air handler with a least three points of support across the bottom of the cabinet at the front, centre, and rear. You want to use flexible duct connections on the supply and return ducts. You want to isolate the refrigeration lineset and condensate drain with anti-vibration hangers and, of course, the electrical conduit should be flexible material the last few feet. The unit should be mounted at least 3 feet away from walls or ceiling to prevent "close coupling" in which the cabinet vibrations are transmitted through the air to nearby structures. Install the unit so that it can be easily serviced, your mechanics will love you for it. I hope this information is of some use.

Do you require a walk path?
Service lights (jelly jar type) near the unit and along the walk path. Exit path marked?
GFIC outlet near unit for service work.
ID Tag on unit.
Name plate information where you can read it.
Insulated condensate piping. Labeled?
These are a few things to look for.
