7. Maintenance and service
7.1 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.

7.2 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
startup operations listed in section
6. Operation
must be repeated. The pump must be filled with
liquid before it is started up again.
7.3 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.

7.4 Service
All the spare parts used in repairs must be
original ones and the accessories must be
approved by the manufacturer so as to be able
to guarantee maximum safety of the machines
and systems in which they may be fitted.
If Grundfos is requested to service the pump,
Grundfos must be contacted with details about
the pumped liquid, etc.
before
the pump is
returned for service. Otherwise Grundfos can
refuse to accept the pump for service.
Possible costs of returning the pump are paid by
the customer.
However, any application for service (no matter
to whom it may be made) must include details
about the pumped liquid if the pump has been
used for liquids which are injurious to health or
toxic.
8. Technical data
Refer to pump nameplate.
