3 How to use the DELTABOOSTER
Users are urgently requested to study these instructions before operating the DELTABOOSTER.
The individual user is personally responsible for handling and using the cleaning system properly and
safely. It is therefore urgent that all users are instructed in detail of how to use the system and they should
all have a copy of
Appendix A on “Operation and Safety Instructions”.
3.1 Safety
Your Nilfisk-ALTO DELTABOOSTER is designed and made in accordance with the latest rules on safety
at work. In order to prevent injuries to yourself and other persons, the following regulations should always
be observed when operating the plant.
1.
WARNING! Never direct the water jet towards people, pets, electric wiring, or
the DELTABOOSTER.
2. WARNING! Never try to clean clothes or footwear on yourself or other per-
sons.
3. We recommend you to wear ear defenders, goggles and protective clothing during operation.
4. Never work barefoot or with sandals.
5. Operator and anyone in immediate vicinity of the site of cleaning should take action to
protect himself from being struck by debris dislodged during operation.
6. Spray handle and lance are affected by a thrust during operation - therefore always hold
the spray handle and lance firmly with both hands.
7. Only activate the trigger by hand. Never tie it up or fix it in any other way.
8. At intervals during operation, the machine should be stopped and the spray handle secured against
inadvertent use by turning safety knob to position O.
9. WARNING! High pressure hoses, nozzles and connections are important for safety when operating
the plant. Only use the high pressure hoses, nozzles and connections prescribed by Nilfisk-ALTO.
1 0. Avoid damage to the high pressure hose such as running over by a car, squeezing, pulling, knot-
ting/kinking etc. and keep it away from oil and sharp or hot objects, as such may cause the hose to
burst.
11. Never use the water for other purposes than cleaning. Detergents etc. may have been added.
12. Never detach the high pressure hose from an outlet point until the high pressure cock at the outlet
has been properly closed and the high pressure hose relieved of pressure.
13. Only let instructed personnel operate the plant.
14. Never let children operate the plant. Denmark: Persons under the age of 18 must not operate the
plant if the working pressure exceeds 70 bar.
15. When using detergents the instructions should always be strictly observed.
16. Persons under the influence of alcohol, drugs and medicine should not operate the machine.
17. Don’t use the machine if important parts of the equipment are damaged - i.e. safety devices, high
pressure hoses, pipeline, spray handle.
Save these instructions for later
The high-pressure pumps of a DELTABOOSTER are fitted with a safety valve each.
The safety valve has been set and sealed from the works.
DO NOT INTERFERE WITH THIS SETTING!
The motors in a DELTABOOSTER are protected against overload as thermal circuit breakers have been
incorporated in the stator windings, and the motor is guarded.
If the motor is subjected to an overload the thermal switches will cut off the system so it stops. After such
a stop the DELTABOOSTER can be restarted without interfering in the electrical system as the failing
motor will automatically be disconnected. After cooling or re-connection of the motor protection, the pre-
viously disconnected motor can be taken into operation again when re-starting the plant as described in
section 3.4.2.
The motor protection disconnects the system if the motor consumes too much power.
Frost protection
The system should be installed in frost-free premises. Pipelines and outlet stations should also be in a
frost-free location. When outlet stations are situated outdoors remember to provide for the cutting off and
draining of that part of the line which is exposed to frost.
If the temperature of the inlet water is above 80°C or below 2°C the plant will be disconnected.
