Filling and Purging the Unit
When the unit has been properly piped, begin the filling process (top piping configuration shown).
1. Open the 2-way bypass shutoff valve by
turning the handle 90° to the right. Using a
2.5-mm hex key, turn the flow control
actuator to the fully open position.
2. Remove the cap from the top coil vent and
push the vent.
3. At the water supply, open the appropriate
valves to begin letting water slowly into
the unit.
4. Stop pushing the top coil vent when water
begins slowly flowing out of the vent.
5. At the water supply:
a. Open all valves no greater than 113
l/m (30 GPM), and allow the water
supply to reach the highest possible
flow to the unit for 45 seconds.
b. Close the valves to a
3.8–11.4 l/m (1–3 GPM) flow for 60
seconds.
c. Open the valves to maximum flow
for another 45 seconds.
d. Balance the system to provide the
designed flow rate to all equipment.
WARNING
ELECTRICAL HAZARD
Ensure that all electrical connections are unplugged before you introduce water into the
unit.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
