INSTALLATION GUIDELINES

1. Space around DG SetThere shall be at least one meter free spare around BLISS DG Set to facilitate DG set door opening and

maintenance.

2. Installation SurfaceThe installation surface must be flat, even, firm and without undulations.

3. Requirement of PlatformConcrete platforms should be foreseen to prevent water entry in situations of flooding.

4. Cross ventilationIf installed in an enclosed space, the room should have cross ventilation allowing fresh air to enter from

alternator side of the canopy and hot air to move out of the room on the opposite side.

5. DG Set orientationIf installed in an enclosed space, the Radiator of the BLISS DG Set should face an opening in the wall for

hot air to escape.

6. Hot Air evacuationSilencer and associated pipes radiates heat. Hence the room must have provision to evacuate hot air

accumulated at the top by ventilator or exhaust fan.

7. Multiple Set OrientationsMultiple DG sets should be installed one beside the other and not one facing the other or one behind

the other.

8. EarthingRegulations vary from place to place. Hence advice should be sought from the local supply utility about

requirements. The frame of the alternator, engine and control panel are all connected. Hence earthing

the frame of the BLISS DG set ensures earthing the body of all the components. The neutral of thealternator has to be earthed separately. The provision for the same is also made in BLISS DG set.

Grounding should be done in accordance with applicable National, Local code/Regulation.

Regulations normally require 4 earth pits, one pair for alternator neutral and the other pair for DG set

body. The earth pits should be separated by not less than 1 meter.

9. Roof top installationsExperts in the respective field like Structural Engineers must be consulted for roof top installations.

10. Exhaust Connections

The exhaust system is used to direct exhaust gases to non-confined areas and reduce the noise totolerable levels. When designing a system, the main objective is to minimise back pressure. Excessive

back pressure in an exhaust system will create horsepower loss and increase the engine operating

temperature and emissions. When bends are required in exhaust system, always make the radius at least

150% of the inside diameter of the pipe. As most exhaust system designs are governed by the physical

characteristics of the building or room in which they are located, it is of utmost importance that the

exhaust pipe be routed in a path offering the least amount of turns or bends so as not to increase back

pressure more than 50mm of Hg. Bevel the end of the pipe at a 30-45 degree angle. Should the pipe end

be horizontal, bevel the pipe from the top back to the bottom. This will not only reduce the noise levels

at the outlet but will also minimise entrance of precipitation on horizontal pipes.

By locating the silencer as close to the engine as possible you will be able to minimise the noise level in

the exhaust piping.

Each DG Set installation should have its own exhaust system and should not be connected to a system

accommodating more than one DG Set as the possibility of exhaust gas and condensation backflow may

cause permanent damage to an idle engine.

11. Balancing the loadsWhile connecting the loads on BLISS DG set, care should be taken to distribute the single phase loads

equally on all the three phases.

12. Power FactorAs per standard, BLISS DG set is capable of providing power at 0.8 power factor (lag).Hence the

maximum kW BLISS DG Set can supply is obtained by multiplying kVA by pf (Which is 0.8).Power factor

lower than 0.8 (lag) will stress the alternator, while pf more than 0.8(lag) will stress the engine. Hence it

is advisable to check KW and kVA loading separately. Leading power factor loads, as presented by power

factor improvement capacitors will cause voltage instability and hence should be avoided on BLISS DG

Set.

UP KEEP1. As a daily routine, clean the BLISS DG Set with dry cloth.

2. Keep the door of the DG Set closed.

3. Dont fill the fuel without strainer.

4. Maintain log book for BLISS DG set.

WATCH KEEP1. Verify battery charge, lube oil level, coolant level & fuel level in the daily

routine checks.

2. Regularly check all the connections of air, oil, coolant, fuel and exhaust for

leaks. Report if

abnormal.

3. Observe loosening of parts, nuts & bolts. Report if abnormal.

4. Observe for unusual sound of set. Report if abnormal.

DOS & DONTSDos.....

1. Ensure that keys for the locks are in proper custody.

2. Use proper & appropriate place for storage of BLISS DG set, Spares and

associated items.

3. Understand information provided in DG operation & maintenance literature

and as conveyed during training & follow them.

4. Ensure minimum 1 meter clear distance between BLISS DG set & all

surrounding structures. Remove obstacles if any for easy access to DG set.

5. Ensure free flow of fresh air to inlet provided on DG set and hot air fromradiator to move out to atmosphere without restriction / reflection.

6. As a daily routine, clean the DG set with dry cloth.

7. Include verification of battery charge, lube oil level, fuel level & water level

in the daily routine checks.

8. Regularly check all connections of Air, Oil, Water, Exhaust & Diesel for leaks.

9. Release start push bottom when speed picks up to prevent damage to self-

starter.

10. Allow sufficient gap between successive starts to prevent draining of

battery.


8/10



11. While operation in manual mode, run for a while on No-load before

loading. Disconnect the load first & run for a while on No-load before stopping

the DG Set.

12. Be alert for any unusual sound of DG Set and report without delay.

13. Maintain DG Run log book, Fuel log book & Visit Register.

14. Ensure maintenance checks are carried out in specified time as suggested in

BLISS user Manual.

Don'ts.....

1. Don't allow DG set to run in inclined position.

2. Don't allow unauthorized person/s to meddle with DG sets.

3. Don't commission the DG set in the absence of authorised Kirloskar Electric

service person/s.

4. Don't fill the fuel without strainer.

5. Don't allow operation of the DG set without proper Earthing.

6. Don't fill the fuel when set is running.

7. Don't bring the naked flame near the battery when it is being charged.

8. Don't press start button when the set is running.

9. Don't disconnect the battery when the set is running.

10. Don't operate the DG with Engine Oil below min mark on the Oil dip stick.

11. Don't start the DG set when there is any fault indication.

12. Don't run the DG set without Maintenance checks as in user manual.
