7. Operation
7.1 Startup
Before starting up, check that the pump is
properly primed; see fig. 8.
Fig. 8 Pump must be primed before
startup
Fill it completely with clean water by means of
the hole provided after having removed the filler
cap on the pump body. This ensures that the
mechanical seal is well lubricated and that the
pump immediately starts to work regularly.
The filling cap must then be screwed back on
carefully.
8. Maintenance and service
8.1 Frost protection
If there is any risk of frost damage, the pump
body must be completely emptied through the
drain cap (see fig. 9) to prevent possible
cracking of the hydraulic components.

8.2 Startup after a period of inactivity
Even at temperatures above freezing, in the
event of prolonged inactivity, it is advisable to
completely empty the pump body through the
drain cap; see fig. 9.
When starting after long periods of inactivity, the
start-up operations listed in section 7. Operation
must be repeated. The pump must be filled with
liquid before it is started up again.
8.3 Periodic cleaning
In normal operation, the pump does not require
any specific maintenance. However, it may be
necessary to clean the hydraulic parts when a
decrease in performance is observed. The pump
must not be dismantled except by skilled
personnel in possession of the qualifications
required by the regulations in force.
Procedure:
1. Remove clean out port plug located below
the inlet port; see fig. 10.
2. Insert a thin device (such as an ice pick or
bradawl) and gently move it in a "push and
pull" motion to dislodge any debris.
3. Reinstall clean out port plug.

Warning!
Do not start the pump until it has
been completely filled with liquid.
Dry operation causes irreparable
damage to the mechanical seal.
Caution
The pump should not be started
more than 20 times in one hour so
as not to subject the motor to
excessive thermal shock.
