8. Service/Maintnance
8.1 Safety regulations
The operator ensures that all mainte-
nance, inspection and installation work is
performed by authorised, qualified
specialist personnel who are thoroughly
familiar with the manual.
Before intervening in the iSave/system;
• The power must be shut off and the
starting device must be locked.
• The pressure in the high-pressure lines
must be drained to the low-pressure
side.
• The water in all connected pipes must
be drained.
Always use suitable safety and lifting
equipment when handling the iSave, and
follow the instructions in chapter 4.3
• When safety equipment has been
adjusted make sure that proper
re-adjustment has been made before
start-up.
• When the system is re-started after
service and maintenance follow the
instructions in chapter 7 and in “Start
and stop procedures” in appendix. 10.2
1. Re-check bolts in the foundation and
the base plate of the iSave and tighten
the bolts to specified torque if
necessary.
2. Visually inspect all pipe connections/
couplings for external leakage.
3. Re-check bolts in all pipe connections/
couplings and tighten the bolts to
specified torque if necessary.
4. Replace filters if necessary.
5. Clean the filter housing and reinstall
filters. Make sure no debris enters the
system.
One day after commissioning:
1. Re-check bolts in the foundation and
the base plate of the iSave and tighten
the bolts to specified torque if
necessary.
2. Re-check alignment of the iSave base
plate and iSave.
3. Visually inspect all pipe connections /
couplings for external leakage.
4. Re-check bolts in all pipe connections /
couplings and tighten the bolts to
specified torque if necessary.
5. Replace filters if necessary.
6. Clean the filter housing and install the
new filter. Make sure no debris enters
the system.
7. Audibly inspect the iSave assembly. If
there is irregular sounds or vibrations
inspect the internals parts of the iSave
and replace if necessary.
Three months after commissioning:
8.2 Support
Danfoss A/S offers commissioning and service at
the system manufacturer’s location. Rated
quotes are offered upon request.
8.3 Maintenance schedule
The schedule of preventive maintenance below
will help ensure that the iSave provides years of
trouble-free performance.
1. Re-check bolts in the foundation and
the baseplate of the iSave and tighten
the bolts to specified torque if
necessary.
2. Re-check alignment of iSave base plate
and iSave.
3. Visually inspect all pipe connections /
couplings for external leakage.
4. Re-check bolts in all pipe connections /
couplings and tighten the bolts to
specified torque if necessary.
5. Replace filters if necessary
6. Clean the filter housing and install the
new filter. Make sure no debris enters
the system.
7. Visually inspect pump coupling and
replace if necessary.
8. Audibly inspect the iSave assembly. If
there is irregular sounds or vibrations
inspect the internals parts of the iSave
and replace if necessary.
9. Check power consumption. If there are
irregular performances, inspect the
internals parts of the iSave and replace
if necessary.
Annually:
1. See above section:

2. See
“Operating- and maintenance instruc-
tion, electric motor”
in appendix 10.9
