Filtration; Performance; Long Periods Of Inactivity; Precautions Against Freezing - Comet HPP RLR 300/250 Mode D'emploi

6.3 FILTRATION

The permitted filtration for this type of pump shall be carried out between
100 and 320 micron.
Filter capacity must be three times greater than the flow rate supplied by
the pump. The diameter of the inlet/outlet openings must be the same as
or bigger than the pump's.
ATTENTION: to ensure the pump works properly, clean the filter
regularly according to how often it gets clogged which depends on
the specific working conditions of each application.

6.4 PERFORMANCE

The performance indicated refers to the pump's maximum performance.
ATTENTION: under no circumstances must the pressure values and
revs indicated on the pump rating plate be exceeded, regardless of
power consumption. Minimum permitted number of revolutions:
450 rpm
Contact our Technical Office if you have any particular requests. For
continuous or heavy duty applications please contact our Technical Office.

6.5 LONG PERIODS OF INACTIVITY

If the pump is not going to be used for any length of time, before starting
it first check the oil level and inspect the valves.
Check for any oil leaks from seals.
If the pump is not going to be used for a long time, it is good practice to
carry out all operations that will guarantee a correct future start (empty all
the water, clean the valve housings, lubricate the seals and all other parts
subject to friction).
If the pump is not going to be used for more than 2 months, follow the
instructions listed in chapter 3.3.4 "Storage".

6.6 PRECAUTIONS AGAINST FREEZING

In those months of the year when freezing is a risk (0°C) we recommend
emptying both the intake and delivery lines by means of the relative plugs.
Do not turn the pump on if there is ice. Failure to observe this instruction
may cause serious damage to the pump.

6.7 PRECAUTIONS TO TAKE FOR EXTERNAL PAINTING

Protect/cover from painting the water discharge area of the pump, located
between the head and body. Also protect the oil seals on the power take-
