FLOW CONTROLLER DESCRIPTION

Figure 1. Flow Controller Dimensions
7602-300 and 301 are insulated flow controllers containing
all flush, fill, and isolation connections for a residential and
light commercial geothermal closed loop system that
require a flow rate of no more than 20 gpm. These con-
trollers are equipped with a large bore 1" FPT fittings for
both earth loop and heat pump unit connections.
Mounting the Flow Controller
The flow controller should be located as close to the unit
as possible to limit the length of rubber hose kit and thus
its associated pressure drop. In general the flow controller
can be mounted in any orientation with the exception of
when the pump shafts are in a vertical position as when it
is laid flat on the floor or any similar position. The
controller is typically mounted in one of three locations.
Be certain there is adequate access to all required flush
ports and valves before mounting.
Stud Wall - Mounting on stud wall with or without
drywall can be accomplished by using the two supplied
lag bolts through the top and bottom center holes directly
into the studs as shown in Figure 2.
Side of Unit - Mounting on the side of the unit can be
accomplished by using the four self-drilling screws
directly into the sheet metal access panels or cabinet as
shown in Figure 3. Be careful not to puncture any
internal piping or other components with the screws.
