4.1.1 Attaching the Overflow Safety

Trap (OST) w

CAUTION: To help prevent aspirate from entering the regulator, wall outlet and pipeline system, an overflow safety trap should be attached prior to its use. Aspirate in the regulator, wall outlet and pipeline system may impair their operation. The use of the overflow safety trap and suction filter will help prevent this and extend the life of suction equipment.

Standard fitting

1. Raise the sleeve and insert the trap into the regulator fitting.

2. Turn the trap clockwise about one and a half turns to engage the threads. The trap does not need to be screwed tight; an O-ring in the regulator fitting provides a vacuum seal.

The trap should rotate freely to allow the desired tubing positioning.

Sleeve

3. Lower sleeve to lock trap in position.

DISS fitting

1. Insert trap into the regulator fitting. Situate the tubing in the desired position.

2. Turn the DISS wing nut clockwise to engage threads and tighten (there is no O-ring, so the vacuum seal depends on a tight connection).

Wing Nut

4.2 Mode Selection

|O|O| (INTER) - Suction is intermittent (cycles on and off) and the suction level can be adjusted with the suction control knob.

O (OFF) - No suction is supplied to the patient.

| (CONT) - Suction is continuous and can be adjusted with the suction control knob.

4.3 Setting the Suction Level

w WARNING: The fitting port of the regulator must be occluded when setting the prescribed suction level. This prevents the patient from receiving higher than required suction levels.

1. Clamp the connective tubing to occlude the fitting port.

2. Turn the mode selector knob to | (CONT).

3. Rotate the suction control knob until the vacuum gauge indicates the required setting.

4.4 Pre-use Checkout

Procedure

w WARNING: The Pre-use Checkout Procedure must be performed before using this equipment on each patient. If the regulator fails any part of the Pre-use Checkout

Procedure, it must be removed from service and repaired by qualified service personnel.

w WARNING: Always connect the regulator to the vacuum source and check its operation before attaching the patient connection.

Before the vacuum regulator is used, it must be tested for correct operation as outlined below. All tests must be performed with the regulator in its normal (vertical) operating position and with a minimum supply vacuum of 500 mmHg (66.7 kPa).
