Limited Warranty Information
Thank you for choosing an Alpine product! We aim to please with our wide range of products
including Fountains, Birdbaths, Statuary, Pond Supplies & More. All of our products are constructed
from the highest quality materials. In the event that we have not achieved our usual standard of
excellence, we will repair or replace the item, at our discretion, within the warranty period. A valid
proof of purchase, with the purchase date clearly indicated, must be provided. Photos of defective
merchandise will also be required to help distinguish the actual cause of the defect. Please read
below for a detailed description of warranty coverage.
• Water Damage
Alpine products are not manufactured to withstand extreme temperatures. Improper storage that
allows water to freeze within a product may cause damage and is considered negligence and will,
therefore, not be covered under this warranty. The use of “hard water,” and/or caustic cleaners, can
affect the paint or other finishes. Failure to keep the unit clean, and use of such additives/cleaners,
will also void the warranty. Please note: for fountains, it is normal for some splashing to occur and
protecting the immediate surfaces is not the responsibility of Alpine Corporation.
• Paint & Color (Retention and/or Loss)
The use of water will cause natural erosion to the color. This area can be touched up using standard
paint. The paint is designed to protect the entire finish against breakdown of color. As with any
product, all finishes with time will gradually fade and discolor. The warranty will only cover against
severe or complete fading within the first year, from date of purchase, with the above exclusion.
• Procedure/Service
Should a warranty/claim be needed, you should contact the retailer from whom you purchased the
product. If that not an option, you can contact Alpine Corporation at www.alpine4u.com. When
contacting Alpine Corporation, you must be prepared to show proof of purchase, provide
photographs, and any other information needed to validate your claim. This may be necessary to
distinguish between a partial or complete replacement of a defective product. The warranty does not
cover any items with multiple parts; the warranty will ONLY cover the individual component of the
unit/item that may be defective. Replacement parts can be made available to a consumer through
the original selling party, or an approved parts retailer. If this is not an option, contact our customer
service department.
• Not Covered Under Warranty
The limited warranty will NOT cover cases of damages due to
1. Damages caused in Transit
2. Inadequate care and/or neglect
3. Environmental and/or natural elements
4. Immersion in water, unless specified
5. Improper Installation/Storage and/or Maintenance
This warranty is void if the product has been damaged by accident, misuse, negligence, improper
installation and/or modifications have occurred. This includes any and/or all defects arising out of
freezing water damage, hard water damage, failure to keep the unit clean and free of harmful
additives such as bleach, chlorine, etc…. which affects the paint and/or parts. This warranty also
does not cover any additional charges or installation, removal, disposal and/or shipping costs or
consequential damage associated with any warranty claim

1. The filter has been designed to be used outdoors, but it does not have to be submerged.
2. Do not plug-in or otherwise use this product if any part of it appears to be damaged or operates
abnormally. Have the product examined and repaired, if necessary, by a qualified electrician.
3. Make a “drip loop” on the electrical cord connecting the filter to the plug by letting a portion of the
cord hang lower than either the filter or the plug.
4. This product is designed to be permanently wired to a main power supply, housed in a dry area
and must be buried.
5. Always disconnect the plug from the outlet before any maintenance or troubleshooting is
performed.
6. Avoid the bulb overheating, switch it off when there is no water inside the filter.
7. Avoid the direct contact with UV-C light which can be harmful to your eyes and the skin.
8. To clean the filter, simply rotate the handle and the filter will self-clean itself.
Choose a more suitable place to install the filter. You will need to dig a six inch deep channel connecting
the blower and upper pond basins. This channel will allow you to bury and conceal the tubing once
connected. You will also need to create a hole partially bury the bio-filter while keeping it in an upright
and level position. The filter can buried in the ground up to the filter clips (See figure 1). Connect your
pump to the filter tubing connector marked by the symbol in arrow with flexible hose. Lay the hose in the
channel. Attach the tubing to the filters connector marked by the symbol out arrow and lay it in the
channel leading to the upper pond basin. You should use stainless steel clamps to create a water tight
seal at all of your tubing connection (filter and pump) (See figure 2). The correct functioning of the UV-C
bulb is indicated by the lighting visible on the top of the outer lid (See figure3). Figure 3 also indicates
how to use the self-cleaning mechanism of the filter.
After submerging the pump in water, plug it to check both the pump and bio-filter performance.
Your filter is designed to let you know when filtration performance declines. Your filter is equipped with
a color-coded pressure indicator located on the container lid. When your filter is operating
effectively, the pressure indicator will display green. If flow rate within your filter drops, performance
also declines and the pressure indicator will display RED (See figure 4). The filter can be opened and
the individual filter component can be cleaned and washed manually. Unlatch the clips and remove
the container lid. Wash the filter sponge with clean tap water.The bio-ball should only be cleaned if
they are highly contaminated and you should only use pond water to preserve the microorganisms
and keep the filter biologically active.When reassembling the device, make sure the o-ring is correctly
positioned for a watertight seal (See figure 5). If the seal is out of place or missing there will be
significant leakage when filter is operating.
If the algae proliferate, it is necessary to check and correct the functioning of the UV-C bulb. To
change bulb, first unplug the pump and bio-filter from its power source. Rotate the lid cover, until the
arrows on the lid cover aim at the arrow on the ring holder (See figure 5). Remove the lid cover from
the top of container lid (See figure 6). Unscrew the UV light assembly counterclockwise and gently lift
out (See figure 7). Allow UV light assembly and light bulb to cool and dry completely before handling.
Once cool and dry, grip the base of the bulb with a dry cloth and gently pull the bulb from the
assembly unit (do not pull on the bulb by gripping the grass element) (See figure 8). Slide new bulb
into place until properly seated. Do not test UV light until the filter has been completely reassembled.
If the bulb works correctly the grass quartz tube where the bulb is placed must be cleaned, make sure
the appliance is switched (pump and bulb ).Open the container lid, remove the central tube which
connects to the lid (See figure 9), extract the glass tube , remove possible calcareous deposits on the
tube using a suitable product. Then reassemble all the parts making sure that the o-rings and gaskets
are correctly placed (See figure 10).
