Max-Flo Waterfall & Filter Pumps

Significant technological and design innovations improve pump performance with greater energy efficiency. The reliable Max-Flo Waterfall & Filter Pumps operate on less wattage than the prior models without compromising flow rate. Max-Flo Models 1350 and higher are fitted with Smart Pump Technology. This internal, self-regulating system tracks power consumption, hydraulics and impeller direction. In other words, these smart pumps use only the required amount of power for operation!

These high performance pond pumps are ideal for filtration systems, waterfalls, and watercourses. Durable "pre-filter" pump cage minimizes pump damage and clogging by selectively screening larger debris particles. Pumps feature convenient carrying handle, keyhole slots for optional fixed mounting and pivot pin fastener for quick and easy access to pump. Includes "Click-fit" coupler for convenient plumbing compatible with other Laguna series pond systems. 3-year warranty.

Max-Flo Waterfall & Filter Pumps are able to process pond water moderately loaded with suspended solids (1/4" to 3/8" depending on the pump model). Because of this ability, these pumps are ideal for use with filtration systems and for creating waterfalls and watercourses. Suspended solids are transported to suitable external filter systems (including pressurized filters) that trap any debris that could potentially pollute pond water, effectively filtering the pond.

Installation:
WARNING: DO NOT plug in the pump before it is correctly and fully installed.

1. Connect a flexible hose (not included) to the "Click-Fit" coupling provided. If using a Universal "Click-Fit" coupling, cut the coupling at the required size by using a small hack saw in order to allow the hose to fit properly and to achieve the best water flow.
2. Insert the coupling, complete with the hose attached, onto the outlet of the pump.
3. Place the pump in the pond ensuring that it is completely immersed in the water and securely installed on a solid, level and elevated platform. If necessary, use the keyhole-shaped slots at the bottom of the pump to fasten it to a secure base.
4. Connect the other end of the hose to filter or waterfall (not included) according to your requirements.

Opening and Closing the Pump Cage
The upper and lower halves of the pump cage are fastened together by pivot pin fasteners. Using a standard flat screwdriver (5mm to 8mm), do the following:
To open the pump cage: Gently turn the fastener counterclockwise by 1/4 turn to release the pin.
To close the pump cage: Gently press on the fastener and turn clockwise by 1/4 turn to lock the pin.

Pump Maintenance
WARNING: Always unplug or disconnect all appliances in the pond from the electrical supply before installing, repairing, maintaining or handling the equipment in the water.

To avoid shortening the life of the pump, follow these simple maintenance procedures.

• Once a week, verify that the pump performance is satisfactory. If you detect a drop in pump performance (such as a decrease in water flow from the pump or to the waterfall) first clean the Pump Cage and hosing. If the water flow is still not fully restored to its original performance, clean the Impeller, Impeller Well, and Impeller Cover.
• The Pump Cage must be cleaned at least once a month.
• When necessary, or at least once a year, clean the pump motor completely (the Impeller, Impeller Well, and Impeller Cover) and check that no limestone deposits, which could jeopardize pump operation, are present.
• To keep the pump in good working order, always replace any worn parts.
• The pump motor has no user serviceable part. If the motor or the electrical cord is damaged, discard the pump.

Cleaning the Pump Cage
The main purpose of the Pump Cage is to keep the pump free of bigger solid particles (or solids) that could potentially clog the pump motor. It is therefore normal that these solids progressively accumulate on the external surface of the cage and, with the passing of time, can diminish the performance of the pump (as evidenced by less water flow to the filter or waterfall). To clean the cage and restore the pump performance to its original level, proceed with one of the following:

• Without removing the pump from the pond, brush off the debris from the external surface of the cage using a broom or similar tool. For best results, brush the cage along the ribs.
• Remove the pump cage from the pond, unlock the pivot pin fasteners and remove the upper half of the cage. Clean all components with streaming water from a garden hose. Reassemble all components with care. Ensure the pump cage is securely locked and the electrical cord is seated properly in position before lifting or operating the pump.

Cleaning the Pump Motor Impeller, Impeller Well, and Impeller Cover
CAUTION: The pump motor includes a high quality ceramic shaft that provides long-lasting, reliable performance when properly maintained. However, extreme care should be taken when handling the shaft during maintenance. Avoid dropping or pressing too hard on it to avoid breakage or hairline fractures, which may cause the shaft to snap while in operation.

Take the pump out of the pond, unlock the pivot pin fasteners and remove the upper half of the cage. Free the pump from the lower half of the cage.

Max-Flo 900

1. Using a Phillips (cross-headed) screwdriver, unscrew the four screws on the impeller cover and remove it.
2. Remove the impeller assembly.
3. Clean all components in clean water only, using a small non-abrasive brush, if necessary. DO NOT USE DETERGENTS OR OTHER CHEMICAL CLEANERS, which could damage the pump and pollute the pond.
4. Reassemble all components with care.

Max-Flo 1500

1. Using a Phillips (cross-headed) screwdriver, unscrew the four screws on the impeller cover and remove it.
2. Remove the impeller assembly by grasping the flange. This operation will cause the Seal Ring to come out of its seat.
3. Clean all components in clean water only, using a small non-abrasive brush, if necessary. DO NOT USE DETERGENTS OR OTHER CHEMICAL CLEANERS, which could damage the pump and pollute the pond.
4. Reassemble all components with care by first placing the impeller assembly and then the Seal Ring on their proper seat. Ensure that the impeller bearing, bushing and O-Ring are correctly placed at the bottom to the impeller well.

Max-Flo 2000/2400/2900

1. Using a Phillips (cross-headed) screwdriver, unscrew the four screws on the impeller cover and remove it.
2. Using a flathead screwdriver, carefully lift out the impeller assembly.
3. Clean all components in clean water only, using a small non-abrasive brush, if necessary. DO NOT USE DETERGENTS OR OTHER CHEMICAL CLEANERS, which could damage the pump and pollute the pond.
4. Reassemble all components with care by first placing the impeller assembly and then the Seal Ring on their proper seat. Ensure that the impeller bearing, bushing and O-Ring are correctly placed at the bottom to the impeller well.

Winterizing the Pump

1. Unplug and remove the pump from the pond.
2. Gently scrub off any dirt and debris with a soft nylon brush.
3. Open the cage by unlocking the pivot pin fasteners and remove the pump.
4. Thoroughly clean the pump and cage as per instructions.
5. In addition, soak the impeller shaft and impeller well in white vinegar for 24 hours and then rinse off with water. This procedure will remove calcium and other mineral deposits from the impeller shaft. If these deposits are not removed, they may cause the shaft to bind and break when the pump is started again.
6. Lubricate all seals with Laguna Silicone Lube (sold separately).
7. Store indoors for best results. Do not store the pump in below freezing temperatures.
8. When re-opening your water feature in the spring, submerge the pump in the pond for 1 hour prior to starting the pump.
