observing the following more general norms:
•
Always operate in accordance with the recommendations of the liquid that is
being used.
•
Check that the hydraulic parts of the pump have not been damaged and are
devoid of leaks; use the pump only if it is in really perfect conditions.
•
Use hoses suitable for the liquid to be injected and the effective operating con-
ditions of the plant, possibly inserting them in protective PVC sheaths.
•
Before bringing the pump to a standstill, it is good practice to neutralize the
hydraulic parts by flushing them with an appropriate reagent (see Chapter

HIFTING AND TRANSPORTING THE PUMP
The pump should always be moved in a vertical (and never in a horizontal) posi-
tion. No matter what the means of transport employed, delivery of the pump, even
when free to the purchaser's or the addressee's domicile, is always at the purchas-
er's risk. Claims for any missing materials must be made within 10 (ten) days of
arrival, while claims for defective materials will be entertained up to the 30th (thir-
tieth) day following receipt. Return of pumps or other materials to us or the autho-
rized distributor must be agreed beforehand with the responsible personnel.

NSTALLING THE PUMP
a. Install the pump in a dry place and well away from sources of heat and, in any
case, at environmental temperatures not exceeding 40°C. The minimum operat-
ing temperature depends on the liquid to be batched, bearing in mind that it
must always remain in a liquid state.
b. Carefully observe the regulations in force in the various countries as regards
electrical installations (figure 3). When the supply cable is devoid of a plug, the
equipment should be connected to the supply mains by means of a single-
pole circuit breaker having a minimum distance of 3 mm between the con-
tacts. Before accessing any of the electrical parts, make sure that all the sup-
ply circuits are open.
