TRICKS OF THE TRADE

* Attach equipment schedule and design criteria to checklist.

* Attach sequence of operation to checklist.

* Attach associated contract detail drawing to checklist.

* Complete missing equipment data sheet for CMMS when providing initial PM workorder requirement.

* Have a system flow diagram when starting up the equipment with estimated flows, pressure, and pressure drops noted on diagram.

* Refer to equipment manufacturers' literature for additional data and requirements.

* This checklist should be completed prior to system commissioning process.

DESIGN REVIEW / TRICKS OF THE TRADE

* Confirm there is safe access to the equipment.

* Confirm there will not be short-circuiting of exhaust air into air intakes and/or other building openings.

* Spot-check cooling capacity by dividing square feet by tons-cooling for sq ft/ton.

* Spot-check total fan static (and velocity pressure) for excessive/inadequate pressure drop.

* Attach equipment schedule and design criteria to checklist.

* Attach sequence of operation to checklist.

* Attach associated contract detail drawing to checklist.

NOTE

* Refer to equipment manufacturers' literature for additional data and requirements.
