DESCRIPTION: Your March hot water booster pump is a non-self priming unit build to handle liquid transfer in heating and cooling

operations. Applications include home heating systems, solar heating systems, heat recovery systems and recirculating water in

domestic and commercial hot water tanks.

Contact the factory for applications other than those listed, and for liquids other than water.

*UL recognition on pumps, file E80954, is for water only.

INSTALLATIONS: The 809 Series pump is assembled and ready for installation. The pump should be mounted with the Electric Conduit Box

(Item 15) on the bottom. The oil ports will then be on the top of the motor. The pump housing should be installed with the arrow on our housing

pointing in the direction of the water flow within the system. If the arrow indicating water flow is not in the direction you require when the motor is in

position, remove the four round housing screws (Item 1) holding the housing to the motor assembly and rotate the housing assembly as required.

Replace the four screws and tighten.

The pump is made up of two basics sub-assemblies. They are the Wet End Assembly (Items 1-10); and the Drive Magnet, Bracket and Motor

ssembly (Items 11-15). To separate the 2 assemblies, simply remove the 4 round head screws (Item 1). The pump will then separate into the 2

sub-assemblies. The water will still be contained within the Wet End assembly unless you loosen the screws (Item 10) on the rear of the Wet End

assembly.

LUBRICATION: The motor should be oiled at least once a year at the start of the heating season with 4 or 5 drops of SAE 20 weight non-detergent

oil in each bearing. If the pump is used year around it should be oiled every six months. Do not over oil. No oiling is required on the ball bearing

motors.

GENERAL SAFETY INFORMATION: Follow all local electrical and safety codes, and the Occupational Safety and Health Act (OSHA). Make

certain that the power source conforms to the requirements of your equipment. Always disconnect power source before performing any work on or

near the electric motor. Caution must be exercised to relieve any pressure in the system and in draining hot water from the pump or the system.

DISASSEMBLY AND REASSEMBLY:

1—The motor assembly (Item 15) can be removed from the Wet End assembly without having to drain the liquid out of the system.

2—Remove four screws (Item 1) and slide the motor assembly away from the Wet End assembly.

3—If you must replace parts inside the pump housing assembly, then first close off the valves that supply water to the heating system or to the hot

water tank. Drain the system to relieve any pressure.

4—After the system is drained and cool enough to handle, then remove the four screws (Item 10) on the rear of the housing.

5—The impeller magnet housing (Item 9) can now be removed. It may be snug fit into the pump housing and it may be necessary to pry evenly,

under the four ears to loosen it.

6—Remaining pump parts can now be lifted out in sequence as shown on the exploded view. Replace any worn or damaged parts. Replace the “O”

ring (Item 3) anytime the impeller magnet housing is removed.
