causing oscillation (vibration). Scale buildup happens if the water has too much hardness and is
something that is greatly accelerated if the water does not have the proper amount of treatment.
Vibration can lead to fracturing and breaking of the shaft and is not covered under warranty.
Scrubbing or ticking noise:
Results from scale build up or the bearings and/or shaft wearing out
allowing the rotor to come in contact with one side of the canister. All eventually lead to “seizing” up.
Not bleeding air from the bearings, improperly treated water and/or high mineral content (hardness
is the biggest problem) and TDS (total dissolved solids) that are abrasive all result in premature
wear of the bearings or scale buildup.
Water:
Since water quality characteristics greatly vary across the USA, some customers get much
longer life out of a pump than others. Filling a boiler with softened water, adding and maintaining
treatment so there’s 1,000-1,500ppm of nitrites is the best thing you can do for pump and boiler life.
While there is a one year warranty on our pumps (from customer’s date of purchase), they must first
be inspected and an attempt made to clean and put back in service before a dealer determines one
to be “failed”. Proper treatment and records must also be present for the warranty to be honored. If
a customer had a water test pass but adds water frequently due to boiling or over-filling from
improper operation this will bring down treatment levels quickly, possibly below the minimum level
of 1,000ppm and void the boiler warranty.
G. End Of Season Care
1. Power:
Leave power on so battery charger will maintain the battery. Turn off
switches and unplug pumps and control plug.
2. Chimney:
Inspect & Clean. Cap the chimney to keep rain water out, re-seal caulk.
3. Cleaning:
Perform a heavy cleaning and also completely remove all soot and
hardened deposits using a putty knife and wire brush. Completely coat
the steel inside all areas of the boiler with WD40 or a light coat of motor
oil using a brush or rag to protect from rust during the off-season.
4. Doors & Covers:
Oil all door hinges and latches. Wet rope seals with WD-40. Re-seal caulk
on all jambs. Coat entire threaded portion of all bolts for doors and covers
with a never-seize product.
5. Plumbing:
Ensure fittings are tight at all locations.
6. Water Jacket:
Over-fill so float pointer is 4” above rubber cap, re-seal caulk.
7. Pump:
Remove bleeder screw, inspect and turn shaft with screwdriver. See
maintenance section for further details.
8. Water Treatment:
Make sure water is tested and has enough Nature’s Comfort water
treatment. See warranty for further details.
9. Misc:
Sand and paint any rust.
Moisture from condensation or rain must not be allowed to accumulate in the firebox,
refractory channel or heat exchanger pipes during the off-season. Failure to perform
preventive maintenance may result in severe corrosion and major damage to the boiler.
This is not covered under warranty.
