Liquid level marking:

During operation, if the liquid level indicator light on, it indicates that the dirt water tank inner liquid has reached 80% of the available capacity, please empty the dirt water immediately after the completion of this operation.

| **
Drainage marking:
On the right side of suction, there is the drainage valve, turn the handle in counterclockwise direction, drain out the dirt water; turn the handle in clockwise direction, close the valve. (Please keep the soft drain hose in the sewerage outlet before discharging dirt water)| **
Cleaning built-in filter marking:
Open the rear door once a month to clean the built-in filter system. Turn down the built-in filter transparent cup in clockwise direction, pull off the metal filter, clean and dry it, and then put it back.|

Pre-filter cleaning marking:
The pre-filter is plug-in design, rotate it and pull out the lid by hand, pull out white filter net, clean and dry it, and put it back. (The pre-filter is recommended to be cleaned at least once a week; if this mobile suction is used frequently, please clean this filter after daily shutdown, suck a cup of water after cleaning is better)| ****

NOTE:
Unstable electricity power supply would cause damage to suction, please operate the suction unit in strict accordance with the power supply voltage specified by nameplate.

Structure & Working Principle

1) Main unit structure

2) Suction Motor Structure

3) Working principle overview
Mobile suction unit working principle:
Connect to correct electricity power supply, turn on the power switch, pick up suction from the shelf, suction unit start to work to suck foreign matter and secretion from patient’s mouth; pre-filter separates solids, dirty blood and secretion, the separated dirty blood and secretions will enter into dirt water tank, the solid particles will remain in the pre-filter (so the pre-filter need to be cleaned regularly).
In order to ensure clean air flow enters into suction motor and the impeller of motor will not be damaged by corrosion, once the sewage in dirt water tank reaches a certain height, the mobile suction unit will automatically stop, empty dirt  water tank manually, after that the mobile suction can start to work again.
Suction motor working principle:
Suction motor’s impeller contains numerous vanes in edge, it is a special design for high pressure. When the impeller is rotating, air between vanes is subjected to centrifugal force and moves towards the edge of impeller. There, the air  enters annular cavity of motor again, then returns to the impeller and circulates again in the same way from the start of vanes. Since the air is accelerated by multiple cycles, air leaves the motor at a very high speed, thus generating suction power.

( 4) Commissioning

1. Keep the mobile suction unit on a plane with a maximum inclination of not more than 2°.
2. Turn on the suction unit: connect to correct power supply, turn on the power switch, power indicator lights up, indicating that power supply is normal; the side exhaust fan works, the mobile suction unit can work normally. Pick up the  suction from shelf (both HVE and saliva ejector are available), the suction unit starts to work, put the suction back, with delay about 10 seconds, suction unit stop working.
3. Automatic stop: connect to correct power supply, turn on the power switch, pick up the suction from shelf (both HVE and saliva ejector are available), suck clean water (about 2.5L, the liquid level indicator light is on; about 3L, the  available volume of dirt water tank is full), when the dirt water tank is full, suction unit stops working.
4. Drainage: Once dirt water tank is full, the suction unit will stop automatically; turn off power switch, put the soft drain hose in sewerage outlet, open the drainage valve on side of suction unit (please refer to the marking), empty the dirt water tank, and close the valve.
