ALL THE PUMP YOU NEED AND MORE
Revised 7-5-12
Fill and Start Procedure
Fill and Start Procedure: Smart Pump –
NOTE: The Smart Pump Multizone is not designed to do a full system purge. You can use the flow
center to purge the interior piping by isolating the loop field and running a hose from the flush port
to the flow center below water level.
 Fill canister by water source until the water level reaches 2” below down tube on the return of the
canister to prevent the system from being air locked. (If pump is running for several minutes and no
water is returning to canister, you may be air locked. Verify this by looking inside the canister to see if
water is returning to the canister.)
 Open vent plug on top of pump head until air is no longer heard and a solid stream of water is viewed,
then tighten vent plug.
 Apply power to drive. You will then see the home screen “u” = 0 (frequency reference).
 Hit the down arrow three times until you see “STUP” (Set Up Menu), then press Enter. “APPL”
(Application Menu) will then be shown.
 Hit up arrow until you see B5-19, then press Enter. Change system pressure from “0” (0000.0) to 25
psi (0025.0) by pressing the “right arrow/reset” key over to the desired integer, change the number by
hitting the up arrow to the desired 25 psi (0025.0), then press Enter.
 The B5-19 will then be shown blinking.
 Hit escape key two times (Home screen frequency reference “u” = 0).
NOTE: Drive will only operate on “home screen/frequency reference”.
 Press the “Run” button to begin drive operation. Read the gauge pressure to ensure the pump is
creating 25 psi. If the gauge pressure is 20 psi or less, then the motor may be rotating backwards.
Disconnect power and rotate two of the three motor leads on the drive connection.
 Stop the drive and continue to the next step.
Operating the Drive/System Start Up –
NOTE: Do not start the following process without a sufficient supply of clean potable water and a
person to help monitor the water level in the canister.
 All valves in the system should be in the fully open position, with the exception of the supply and
return loop field valves after bypass, these should be in the closed position (refer to diagram on pg 13).
 If using the Smart Pump Multizone to purge interior piping, then you must have a bypass after the heat
pumps, diverting water/air from supply of loop field to return of loop field (refer to diagram on pg 13).
 Press “Run” button to start drive and begin filling your system while checking fluid level and supplying
clean potable water as necessary to keep the water level above the return down tube in canister.
 When all air is purged from the interior piping, you can then open up the loop field to circulate fluid
through the entire system.
 Inspect the level in the canister and run the system until there are no micro-bubbles returning to the
canister (may need up to a twenty-four hour run-time period).
 Proceed to heat pump balancing and system pressure adjustment.
