Your Guzzler® GE‐0404N/GE‐0504N 24 vdc diaphragm pump ships fully as‐ sembled. Included with the pump is a spare diaphragm. Additional dia‐ phragms can be purchased through your maple equipment dealer or directly online from The Bosworth Company at www.thebosworthco.com. Your pump’s serial number can be found on the side of the pump gear‐ motor, as shown in Figure 1. Power Requirements The GE‐0404N/GE‐0504N pumps require 24 vdc power. The pump motor is Pump serial number on side of motor a 100 watt motor with rated output current of 6.0 A. When connected to Figure 1 two 60 amp‐hour 12 vdc deep‐discharge batteries wired in series, the pump can operate for 30‐50 hours depending on the amount of sap it transfers in that time and on the level of vacuum it pulls. The above results were obtained based on the pump creating 20 in Hg vacuum. Higher levels of vacuum will shorten the length of time the pump can operate before the batteries need recharging. The pump on/off switch is located on the side of the electrical junction box. (Figure 2) Testing the Pump Before installing the pump in your sugarbush, test your pump by connec ng it to power and turning the Power switch to On. Be sure to connect the On/Off switch and fuse on side of posi ve (red wire) lead from the motor to the posi ve terminal on the electrical junc on box. ... -

If you in‐ stall your pump in an enclosure, ensure that it provides ventilation so that the pump motor has adequate airflow during operation to prevent overheating. Quick Connect Couplers between Guzzler and Mainline We recommend the use of Quick Connect Couplers between the pump inlet and mainline so that the pump can be easily disconnected from and reconnected to your mainline. Install Shut‐off Valve and Vacuum Gauge at Pump Inlet We recommend that you install a shut‐off valve and a vacuum gauge – in that sequence – “in front of” the pump, ... -

Eliminate Leaks for Best Vacuum Your Guzzler Pump can develop 19‐28 in. of Hg vacuum, depending on whether the valves are dry or wet. Because the Guzzler is a low‐cfm (cubic feet of air per minute) pump, even very small leaks can prevent the pump from deliv‐ ering its rated vacuum. Maintain your tap lines to keep your system tight and address problems that can cause vacu‐ um leaks. Isolate the Pump to Find Cause of Vacuum Loss If you experience a loss of vacuum in your system – as registered by the gauge near the pump – slowly turn the shut‐ off valve to isolate the pump from your mainline. DO NOT SHUT THE VALVE SUDDENLY, AS PUMP DAMAGE MAY RESULT. If the gauge begins to return to normal operating vacuum, then the pump is working properly, and the source of the leak is somewhere in your sap lines or taps. If the pump fails to recover normal vacuum, then the pump is the source of the problem. Inspect the pump diaphragms and/or valves for any holes or tears. In the case of the valves, check for and remove any material that may have entered a pump body and lodged in the valve, pre‐ venting the valve from proper opening and closing. Keep Ice from Forming Inside Pump Sap can freeze within the pump body. If the pump is turned on when there is ice in a pump body, it will result in damage to various pump components, including the pump body, valves and diaphragm. If there is a risk of freezing conditions, we recommend that you disconnect the pump from your sap lines when the pump is not running and drain any excess sap from the pump. Some users install a small heat lamp in the enclosure with the pump to prevent ice from forming when the pump is not operating. Drain Sap if Removing Pump from Mainline To shut the pump down and disconnect it from the mainline, first slowly close the shut‐off valve to isolate and main‐... -

Over time, the elastomer components of the pump (i.e., the diaphragm and valves) will fail. If a diaphragm fails, the pump may continue to develop some vacuum (depending on the size of the hole/tear), but it will be significantly reduced, and you will see sap leaking from the diaphragm in and around the pump guard. When replacing the diaphragm, pay close a en on to the orienta on of various parts. The use of witness marks may be helpful during reassembly.

Pump Valve Types There are two valves in each Guzzler pump. One valve is locat‐ ed between the pump body and the inlet port; the other, be‐ tween the pump body and the outlet port. Your Guzzler pump may be equipped with either duckbill valves or umbrella valves, depending on the pump options chosen. GE‐0504x Duckbill valve GE‐0404x Duckbill valve (le : Closed; right: Open) (le : Closed; right: Open) The duckbill valve is shaped like a bird’s beak. When pressure is Figure 8B Figure 8A placed on the outside of the beak, it forces it to close; when pressure is placed on the other end of the valve, it forces the beak to open so that fluid may pass. (Figures 8A‐8B) The duckbill valve on the GE‐0504x series pumps is slightly larger than that on the GE‐0404x pumps. The other kind of valve available for your pump is an umbrella valve. The umbrella valve features a rubber valve with a flat round disk held under ten‐ sion against a plastic plate (the “valve stop”) that contains a number of holes or “pores”. (Figure 9) When pressure is applied to one side of the valve stop, it pushes the rubber Figure 9 disk away from the holes, like an umbrella turning inside out (Figures 10A‐ 10B). When this happens, fluid or air can pass through the holes. When the pressure is reversed, the rubber disk is forced against the holes, making a tight seal to prevent any fluid or air from passing. Either kind of valve can be fouled by material in the sap (e.g., wood shavings from taps, plastic shavings from tubing, etc.) ... - Page 8 Changing the Valves, con nued 4. To replace the umbrella valve, use a pair of pliers to grasp the flat por on of the old umbrella valve and pull the en re valve through the valve stop center retaining hole (Figure 12).

The pump motor has built‐in protec on to guard against excessive load con‐ vacuum (27 in Hg) and then di ons, as can occur if the pump is pulling a vacuum in excess of 25 in Hg. stopped. My ba eries are fully Even if the ba eries are fully charged, the motor controller may determine charged. What’s wrong?” that there is insufficient voltage available to support the load on the motor. In some cases, keeping the ba eries charged (as can be done, for example, with a solar recharging system) and opera ng on the range 25.0‐26.0 vdc can provide sufficient power to support loads generated by vacuums on the range 26.0‐28.0 in Hg. If this is not prac cal, then it is recommended to reduce the vacuum that the pump is pulling to a maximum of 25 in Hg so that the pump will con nue to operate un l the ba eries have discharged to the point of providing 18‐20 vdc.
