FCI WATERMAKERS, INC. 101 Maintenance & Repair
AFTER 50 HOURS / BREAK-IN PERIOD
• Change oil in high‑pressure pump
• Check low pressure pump for leaks
• Check inlet hosing and all connections for leaks
PERIODIC MAINTENANCE
Do a 10‑minute visual inspection of the entire system every 500 hours. Start the system
and trace the lines from the feed thru‑hull to the discharge thru‑hull, as well as the fresh
water line to tank. This type of preventative check can save time and money in the future.
INLET THRU HULL FITTING
Keep the inlet thru hull fitting free and clear of debris and marine growth.
LOW-PRESSURE PUMP
Replace the seal every 1,500 hours or when a leak develops. Refer to "LOW
PRESSURE PUMP / MAINTENANCE & REPAIR" on page 105.
PRE-FILTER
The pre‑filter is changed as needed. The cartridge should be changed when the
low‑pressure reading reaches 5‑7 PSI. The cartridge can be cleaned once, using a
soft brush or a nozzle on the end of a hose. Gently separate the pleats and remove as
much debris as possible. Be careful not to fray the filter material. If the filter shows
signs of fraying or does not come clean, replace the cartridge. The cost of a cartridge
is not worth the risk of damaging a membrane or high‑pressure pump seal.
HIGH-PRESSURE PUMP
Replace the seals every 1,000 hours and the valves every 1,500 hours. Replace
the oil the first 50 hours and every 500 hours thereafter. Refer to "HIGH
PRESSURE PUMP MAINTENANCE & REPAIR" on page 111.
