MAINTENANCE
General
Periodically inspect the entire system for leakage and chafe on the tubing and hoses.
Repair any leaks you find as soon as practical. Some salt crystal formation around the
Spectra
- Pearson Pump blocks is normal. Wipe down any salt encrusted areas with a
damp cloth.
Pre - filters
Service the pre - filters as soon as the feed pressure drops 10psi from when new filters
were installed.
To service the filters shut off the system including the feed water supply pump. Open
the housings and discard old filters. Clean out the housing bowls, check and lubricate
the o
- rings with silicone grease and reassemble the housings with new 5 micron filter
elements. Leave dry until next startup.
Use only Spectra approved pleated polyester filters
or you may void your warranty.
General pump maintenance
The Boost (feed) pump requires no routine mainte-
nance except inspection for leaks. The oil in the Pearson pump crankcase should be
changed every 5000 hours or if it becomes contaminated with water (milky). Any leaks
should be addresses asap. If tightening a fitting does not stop the leak, unscrewing
the leaking fitting, cleaning the mating surfaces, lubricating everything with silicone
grease an reassembly will often solve the problem.
Pearson pump
As with all high pressure pumps the seals in the Pearson Pump need to be replaced
from time to time. For preventative maintenance we recommend changing the seals at
2500 hour intervals (the Seal Change Manual is an appendix). The pump will likely re-
quire a complete rebuild at 10,000 hours though this can be performed when indicated
by leaking or changed in recovery rate. If the recovery rate drops more than 5% the
valves need to be replaced (which is part of the 10,000 hour rebuild).
