6. Startup
1. Turn on the water supply. Allow the system to fill.
2. Immediately inspect for any leaks.

Inspect for leaks before operation
3. With the pump not running, allow maximum water flow, for
example remove handset from shower hose.
4. Operate maximum hot and cold flows for at least two minutes
to flush out all debris. See fig. 26.

5. Switch on the power supply, run the pump for a few minutes,
switch off, drain down and clean the inlet strainers. See fig.

Cleaning the inlet strainer
For SSN, SSP, STN and STP pumps, remove the inlet hose from
the pump, and the strainer basket can be removed by hand or
with long-nosed pliers.
6. Replace the inlet strainers and reconnect the hoses.
7. Turn on the water supply. With the power supply off, allow
maximum water flow, for example remove handset from
shower hose.
8. Operate maximum hot and cold flows for at least five minutes
each to ensure air is thoroughly purged from the system.
9. Replace handset on shower hose.
10. Switch on the power supply.
11. Operate the pump in both full hot and cold modes for at least
two minutes each while inspecting for leaks.

12. Check that all hot-water connections are tight and not leaking,
when the hot water has been run for several minutes. See fig.
28.

The first few times the pump is used, the insulating varnish used
on the pump motor may give off an odour. This is perfectly normal
and will diminish with use.
6.1 Shaft seal run-in
The seal faces are lubricated by the pumped liquid, meaning that
there may be a certain amount of leakage from the shaft seal.
When the pump is started up for the first time, or when a new
shaft seal is installed, a certain run-in period is required before
the leakage is reduced to an acceptable level. The time required
for this depends on the operating conditions, i.e. every time the
operating conditions change, a new run-in period will be started.
Under normal conditions, the leaking liquid will evaporate. As a
result, no leakage will be detected.
Do not start the pump until it has been filled with
liquid.
Before startup, flush the system with clean water and
drain to remove possible impurities.

Run the pump for five minutes or more at least once
every four weeks in order to prevent the pump from
seizing up. Scale buildup can cause the pump parts
to stick.
