KWC is an intelligent water replenishment and water change equipment, suitable for occasions such as water replenishment and water change in sea aquariums.
The device can be controlled locally through the App. The device has an optical level sensor(Anti-overflow sensor). It is used to control the start and stop of equipment water replenishment and the overflow prevention of water change; It has a float level sensor(Waste liquid anti-overflow sensor).It is used to prevent the overflow of the waste liquid bucket ； It has three anti-dry-burning submersible pumps, namely, discharge waste water pump （ Q270-S ） , supplementary sea water pump（Q270-S）, and supplementary fresh water pump（Q270-F）. When the replenishing water overflows, the replenishing bucket lacks water and the replenishing water is overtime, the KWC will have an indicator light and a buzzer to alarm.
P1:Discharge Sea water pump and Low liquid level detection(Q270-S)
P2:Add Sea water pump and Low liquid level detection(Q270-S)
P3:Add Fresh water pump and Low liquid level detection(Q270-F)
S1:Refill and Anti-overflow sensor
S2:Waste water Anti-overflow sensor
Step 1: The optical sensor (S1) is installed on the normal water level of the aquarium and use it as a water replenishment and anti-overflow sensor.Note that the optical level sensor should be far away from the place with bubbles, otherwise it will be interfered and misjudged;
Step 2: The float sensor (S2) is installed on the top of the waste water bucket as an anti-overflow sensor. If the water level reaches this position, it means the waste water bucket is full, and the device will alarm to remind the waste water bucket to be full to prevent the waste water bucket from overflowing;
Step 3: Connect the pipeline (refill pump-- siphon break -- tube holder). Discharge Sea water pump and Low liquid level detection（P1）is placed in the aquarium and connected to the waste water bucket through a pipeline; Add Sea water pump and Low liquid level detection (P2) is placed in a bucket of fresh sea water and connected to the aquarium through a pipeline; Add Fresh water pump and Low liquid level detection(P3) is placed in a fresh water bucket and connected to the aquarium through a pipeline.
Step 4: According to the wiring harness label, connect the submersible pump to the corresponding interface The anti-dry burn identification sensor of the refill pump should be kept upward, so that when the water of the freshwater reservoir is insufficient, it can be timely found and alarm.
Step 5: Plug the power adapter into the DC12V connector and power the power adapter. Note: The model of make-up fresh water pump is Q270-F, and the model of waste water pump and make-up sea water pump is Q270-S. it cannot be installed reversely during use.
