5-2. Instructions for the air vent operation
During operation, air that remains after water is supplied to the water circuit is removed from the water circuit.
Perform this operation
after water and refrigerant piping work, air tightness test, evacuation, and refrigerant
charging have been completed and electrical work is done.
(And after the debris removal operation if it is performed)
5-2-1.Preparation for the air vent operation
5-2-2.Air vent operation
1.Open the air vent valves on the HBC controller and indoor unit.
Refer the Installation Manual for the location of air vent valves.
(If there are air vent valves on the field-installed pipes, open the valves as well.)
3.Supply water from the suction pipe on the HBC controller.
2.Set DIP SW 5-1 (valve opening when stopped), DIP SW 5-2 (nullification of drain over-flow error for 9 hours) from off
to on.
4.
Check that water comes from each air vent valve, and perform the air vent operation.
1.Set DIPSW4-3 from OFF to ON.
3.Close the all air vent valves.
5.Set DIP SW 5-1 and 5-2 to off.
4.Stop the water supply.
5-2-3.Checking for the presence of residual air
1.Set DIPSW4-5 from OFF to ON, and operate the water pump.
2.If there is residual air in the circuit, it will be noisy. Check for water leaks from the pipe, and then, perform the air
vent operation again.
Step 1
Step 2
(1)Each step can be skipped by setting DIPSW4-2 from OFF to ON.
(2)The operation can be forced to stop by setting DIPSW4-4 from OFF to ON.
(3)If insufficient air vent is detected at each step, go back to step 1.
The operation is performed while air is
discharged from the water pipe. [Air0 to Air1]
The residual air will be roughly removed
by operating all indoor units. [Air2]
Intermittent operation of water pump (20 min)
Operation of all indoor units (20 min)
Step 3
Step 4
The residual air will be removed by operating
indoor units for each branch. [Air3]
The saturated air in the circulating water will be
removed by performing heating operation for all
indoor units and raising the temperature of the
circulating water. [Air4 to AirE]
Operation of individual indoor unit (10 min per one branch)
Heating operation of all indoor units (20 min)
Flowchart for air vent operation (DIPSW4-3 is ON.)
2.When 130 minutes have passed after the operation startup, water pump will stop, and the LED display on the
HBC controller changes from “Air0” to “Air1”, then from “Air1” to “Air2”, then from “Air2” to “Air3”, then from “Air3” to
“Air4”, then from “Air4” to “AirE”. (Refer to the flowchart for air vent operation for details.)
Install a non-return valve to prevent water in the water circuit
flooding back to the water supply pipe, or remove the water
supply hose after the air vent operation.
