1. SUMMARY
Before installation and operation
ˈ
read this Service Manual carefully
Check package for damage. If found file claim with carrier and notify EURUS.
Must be carefully when operating rotary blowers, see Safety Instructions
Make sure both driving and driven equipment is correctly lubricated before
start-up, see Oil Capacities and Recommended Lubricant.
In event of trouble during installation or operation, do not attempt repairs of
blower. Notify Eurus, giving all nameplate information, Will received a
technical service. See Operating a Rotary Blower
Before install the blower, See Installation and Design Requirements.
Store the rotary blower in a dry, covered space, see Storage.

2. FOREWORD
ZZ Series blowers are the result of advanced engineering and skilled
manufacturing. To be assured of receiving maximum service from this
machine, the owner must exercise care in its operation and maintenance. This
manual is written to give the operator and maintenance department essential
information for day-to-day operation, maintenance and adjustment. Careful
adherence to these instructions will result in economical operation and
minimum downtime.
Danger is used to indicate the presence of a hazard which will cause
severe personal injury, death, or substantial damage if the warming is
ignored.
Warning is used to indicate the presence of a hazard which can cause
severe personal injury, death, or substantial damage if the warming is
ignored.
Caution is used to indicate the presence of a hazard which will or can
cause minor personal injury or property damage if the warning is
ignored.
Notice is used to notify people of installation, operation or maintenance
information which is important but not hazard-related.

3. SAFETY PRECAUTIONS
Safety is everybody’s business and is based on your use of good common
sense. All situations or circumstances cannot always be predicated and
covered by established rules .Therefore, use your past experience ,which out
for safety hazards and be cautious .Some general safety precautions are given
below.
Failure to observe there notices could result in injury to or death of personnel
zKeep fingers and clothing away form revolving fan, drive coupling, etc.
zDo not use the air discharge from this unit for breathing-not suitable for
human consumption.
zDo not loose or remove the oil filler plug ,drain plugs, covers or break any
connections ,etc., in the blower air or oil system until the until the is shut
down and the air pressure has been relieved.
zElectrical shock can and may be fatal.
zBlower unit must be grounded in accordance with the National Electrical
Code .A ground jumper equal to the size of the equipment ground conductor
must be used to connect the blower motor base to the unit base.
zOpen main disconnect switch, tag and lockout before working on the control.
zDisconnect the blower from its power source, tag and lockout before working
on the control.
Failure to observe these notices could result in damage to equipment
zStop the unit if any repairs or adjustments on or around the blower are
required.
zDisconnect the blower from its power source, tag and lockout before working
on the unit-this machine maybe automatically controlled and may start at any
time.
zDo not exceed the rated maximum speed shown on the nameplate
zDo not operate unit if safety devices are not operating properly. Check
periodically. Never bypass safety devices.

Notes: 1. The user can select the configuration according to their installation requirements.
2. The effective volume flow is dependent on the speed and the differential pressure.
3. The power consumption is dependent upon the operating point required, e.g. volume-flow
and differential pressure.
4. The ratings based on inlet air at standard pressure of 14.7 psia, standard temperature of 68
degrees F, and specific gravity of 1.0.
5. p = discharge pressure – inlet pressure
4.2. Ambient Temperatures
Minimum ambient temperature *………........................................................ 5 °F
Maximum ambient temperature *…………………………………. .............. 104 °F
* These temperature limits are based on lubricants specified here within. Consult Eurus
