12. STOPPING THE PUMP FOR LONG PERIODS
12.1 Inactivity for long periods
If the pump is started up for the first time after a long peri-
od from the shipment date, before starting operation
check the oil level, check the valves as indicated in
Chapter 10, and therefore follow the start-up procedures
described.
12.2 Filling the Pump With An Anti-Corrosion
Emulsion or Anit-freeze Solution
a) Close the filter draining, if open.
b) Be sure that the connecting hose is clean, spread
with grease and connect it to the high pressure outlet
port.
c) Fit a suction hose to the membrane pump. Open the
pump suction connection and fit hose between it and
the membrane pump.
d) Fill the container with the solution/emulsion.
e) Put the free extremeties of the suction line and the
high pressure outlet hose inside the container.
f) Start up the diphragm pump.
g) Pump the emulsion until it comes out of the high
pressure hose.

In order to increase life of hydraulic compo-
nents of the fluid ends, a flushing operation
with clean water is recommended after every
daily operation
h) Continue pumping for at least another minute; if
needed, the emulsion can be reinforced by adding,
for example, Shell Donax
i) Stop the pump, remove the hose from the suction
connection and close it with a plug.
j) Remove the hose from the high pressure outlet port.
Clean, grease and plug both connections and the
hoses.
12.3 Hoses
a) Before greasing and protecting the hoses according
to the previously described procedure, dry the con-
nections using compressed air.
b) Cover with polyethelene.
c) Do not wrap them too tightly; be sure there is no
bending.
13. PRECAUTIONS AGAINST FREEZING
In areas and periods of the year where there is
risk of freezing, follow the instructions indicated
in Chapter 12 (see paragraph 12.2).
In the presence of ice, in no case must the
pump be started until the entire circuit has
been completely thawed out; not complying
with this indication may cause serious
damage to the pump.
