How to Order
Coil Detail from Job Plan — Step 1
The Flow Design sales representative will take-off the coil detail requirements for all types of terminal
units on the job plan: fan coil, fin tube, unit heater, air handler, or VAV box. All functional requirements of
the plan detail will be incorporated into the IMI Flow Design Hook-Up. Occasionally there may be slight
modifications made to the plan detail so that it will conform to ASHRAE and industry standards. The
representative will then convert the standard plan detail into compact, labor saving modules.
Quotation — Step 2
IMI Flow Design will provide a component drawing and price sheet of a modular Hook-Up for each type
of terminal unit on the plan. The module will have all the functions of the plan detail. The price sheet will
show a price for each size and type, as well as prices for several options:
• Factory installed ATC valves – At the contractors option the ATC valves may be consigned
to the IMI Flow Design factory. The components will be attached to the valve and tested as an
• Extensions for insulation – The standard valve handles, P/T plugs, air vents etc., will clear 1′′
thick insulation. Thicker insulation requires extensions which are priced under options.
Submittal — Step 3
IMI Flow Design will prepare a shop drawing showing the Hook-Up module arrangement for each type
of terminal unit. The drawing has a brief description of each component. Standard submittal forms for
all components showing dimensions, construction and ratings are attached.
Order Entry — Step 4
To enter an order the IMI Flow Design representative must obtain the ATC valve schedule (sizes will be
needed), coil and runout sizes, and types of connections (sweat or threaded). A drawing will be prepared
showing the runout size, ATC valve size, coil connection size, and their types of connections.
Several Hook-Up in the same group may be shipped in one box.
