w Respironics recognizes the need for outside centers to maintain their own equipment. To ensure quality service, Respironics has developed a Service Center Certification Program consisting of two parts; facility inspections and personneliraining and certification.

The Service Center Certification is designed to ensure that a certified service representative has at their disposal the proper facilities necessary to complete quality repairs.

Only those facilities which	are authorized Respironics	Service Centers are
sold replacement parts. For information on becoming		an authorized service
center contact Technical	Services at 800/669-9234,

Servicing Guidelines

SECTION 1.0

Introduction

W A unit passes Operational Checks if no discrepancy is discovered in unit operation otherthan; internal battery replacement, or other minor repairs or adjustments that do not require disassembly of the unit other than the top cover.

If the unit is	being	serviced	due to a complaint,	perform Operational	Checks in
Section 5.0	to find	any other	discrepancies with	unit operation. The	steps in

Sections 6.0 through 10.0, including Preventive Service MUST aiso be performed, regardless of the number of hours remaining.

A unit automatically fails operational checks if any mandatory ECO is not installed.

Refer to the flow chart on the next page for a further description of servicing guidelines.

SECTION 2.0

Warnings and Cautions

This is a non-continuous ventilator and is intended to augment patient breathing. It must not be used as a ventilatorthatsupports or sustains life, and it is not intended to provide the total ventilatory requirements of the patient.

Airflow		generated			by	this device is limited to		150 liters per	minute. The
selection of			certain		combinations of settings (i.e.,			high rate and short risetime)
may	result		in	a situation where			pressure support	levels cannot	be	obtained.
The	use	of	a	water	trap	and/or	hydrophobic filter	is recommended		to prevent

moisture from entering the ventilator.

The use of bacteria filters are recommended to ensure client safety from cross contamination.

DO NOT use the QUANTUM			PSV	in the	presence of flammable anesthetics.
Never operate		this device	if the	power	cord	is	damaged.
Do	notuse this	device if ithas been dropped				or	damaged. Contact your dealer
or	Respironics	immediately.

Use only an identically rated and sized fuse for replacement.

Oxygen	vigorously	accelerates	combustion.	Keep this	device	away from heat
oropen	flame when	using supplemental oxygen. This device must be running
before turning on the supplemental oxygen.				Turn off the	oxygen	before turning
the device off. Do		not smoke	within 6 feet	(2 meters)	of this	unit.

Do nat block any air intake vents.

Do not kink or crimp air outlet hoses.

Always unplug the Quantum PSV before cleaning the enclosure.

Performance verification of the Quantum PSV must be performed before use.

The Quantum PSV must be periodically checked and maintained to ensure

properoperation.					+
Connect	the	Quantum PSV	to	a grounded	hospital grade	outlet	only.
Quantum	PSV	performance	is	affected at	temperatures	below	5°C and
above 40°C.

SECTION 2.0

Warnings and Cautions

+ Replace the back panei shipping fuse, as required, with a 3-amp 250V fast blow fuse, 5mm x 20mm.

* Positioning the Quantum PSV must not block the air intake ports located on the rear panel.

¢ Verity that the alarms are operational.

*Connect only Model 7703 Remote Control cables or other certified Sleep

Recording	Devices into	the signal output part (SOP) ofthe	Quantum PSV. Do
not insert	any devices	into the signal input part (SIP) of	the Quantum PSV.

*All ESDS items must be stored in approved conductive packaging, tubes,

shipping bags, foam, or tote bins.

	.		.
	All persons handling ESDS items must be grounded		via a 1 Meg ohm
	resistive grounded	wrist strap.

Coverall ESDS bench tops with grounded conductive mats and connect ail work surfaces and equipment to earth ground.

sTransport all assemblies containing ESDS items in a conductive bag or container.

ο:	DONOT use cellophane adhesive tape to wrap DIP (dual in-line package)
	tubes together.

* © DONOT handle ESDS items by their pins or mix them with other routine electronic parts.

e Never place ESDS items on ungrounded surfaces or leave them unattended in an open area.

*‘Avoid cellophane wrappers, synthetic carpeting, warm or cool air blasts,

styrofoam coffee cups, etc. when working with ESDS items.

+Use only ESD safe solder suckers, grounded soldering irons, and

grounded DIP installation tools.

+Use only properly designed heat lamps, heat chambers, and/or “antistatic” quick-chill sprays during troubleshooting or stress testing procedures.
