1. SUMMARY

Before any installation or operation, read this Service Manual carefully. Check the

package for damage. If blower is damaged file a claim with the carrier and notify EURUS.

Use care when operating the rotary blowers, see Safety Instructions Make sure both drive

and driven equipment is correctly lubricated prior to start-up, see Oil Capacities and

Recommended Lubricant.

In the event of trouble during installation or operation, do not attempt repairs of blower.

Notify Eurus, giving all nameplate information and you will receive technical service. See

Operating a Rotary Blower

Before installing the blower, See Installation and Design Requirements.Store the rotary blower

in a dry, covered space, see Storage.Always operate rotary blowers in a dry and dust free

environment, SeeOperational Characteristics and Construction.

2. FOREWORD

ZZDSL Series blowers are the product of advanced global engineering and

manufacturing. To receive maximum service and performance from this machine, the

owner is advised to exercise extreme care in its operation and maintenance. This

manual is written to give all operation and maintenance personnel essential information

for day-to-day operation, maintenance and adjustment. The use of these instructions

will result in economical operation and downtime.

Danger is used to indicate the presence of a hazard which will cause

severe personal injury, death, or substantial damage if ignored.

Warning is used to indicate the presence of a hazard which can cause

severe personal injury, death, or substantial damage if ignored.

Caution is used to indicate the presence of a hazard which will or can

cause minor personal injury or property damage if ignored.

Notices are used to notify all concerned of any installation, operation or

maintenance information which is important but not hazard-related.

3. SAFETY PRECAUTIONS

Safety is everyone’s concern and is based on the use of good common sense.

Situations or circumstances cannot be predicated or covered by established

rules .Therefore, use past experience , watch out for safety hazards and be

cautious .Some general safety precautions are given below.

Failure to observe these notices may 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… it is 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 blower 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 blower 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

4.4. Oil Capacities

At the drive end, the bearings are lubricated by the slinger, which must be on the lowest rotor

when in a vertical configuration.

At the gear end, the timing gear teeth are lubricated by being partially submerged in oil. The

gear teeth serve as oil slingers for gear end bearings.

4.5. Recommended Lubricant

Use the appropriate grade and viscosity of industrial type, non-detergent, rust inhibiting,

anti-foaming oil (Reference Chart 1 below). The correct oil depends on the range of

ambient temperatures as well as the range of discharge temperatures.

Synthetic lubricants are highly recommended over mineral lubricants: synthetics last up to 4 times

longer; and a single viscosity can cover a broader temperature range.

Consult factory for oil recommendations on special applications.

4.6. Nameplate

The nameplate of the rotary blower is located on the oil cover gear side
