It is best to install your Guzzler G2
SapPuller
pump at or
above collection tank level to avoid shortening diaphragm
life.
Your Guzzler G2
SapPuller
pump should be securely mount-
ed to a mounting surface prior to operation. The support
bracket of the pump has a mounting leg with two holes that
accommodate a 1/4 in (6.4 mm) diameter bolt or screw.
(Figure 3)
The inlet manifold of the pump should be secured
to the mounting surface using the two “C”-clamps provided
with the pump.
(Figure 4)
Your Guzzler G2
SapPuller
is equipped either with 1-1/4 in
(3.2 cm) Female (inside threads) or 1-1/4 in (3.2 cm) Male
(outside threads) ports on the inlet and outlet manifolds.
Depending on how your pump is configured, you can connect to your sap lines by screwing a 1-1/4 in (3.2 cm)
fitting either into or onto the pump manifold ports. We recommend connecting your pump to the mainline with
Quick Connect Couplers so that the pump can be easily disconnected from the line.
The pump should be protected from the weather. If it is placed in an enclosure, be sure to allow adequate air-
flow around the motor for cooling.
The Guzzler G2
SapPuller
requires 12 VDC power. Connec ng your
pump to two 60 amp-hour 12VDC deep-discharge ba eries should
provide 10-12 hours of pump opera on before requiring recharging.
(The motor is rated for 14.0 amps at full load.)
The Guzzler G2
SapPuller
pump is capable of developing 22 in. of Hg
vacuum (0.7 bar), but it is a low-cfm (cubic feet of air per minute)
pump. This means that even very small leaks can prevent the pump
from delivering its rated vacuum. Maintain your tap lines to keep your
system tight and address problems that can cause vacuum leaks.
When installing the Guzzler
SapPuller
, we recommend that you install
a shut-o
ff
valve and a vacuum gauge – in that sequence – “in front of”
the pump; i.e., just before your connec on to the pump’s inlet mani-
fold.
(Figure 5)
If you experience a loss of vacuum in your system – as registered in the gauge near the pump – slowly turn the
shut-o
ff
valve to isolate the pump from
your mainline. DO NOT SHUT THE VALVE
SUDDENLY, AS PUMP DAMAGE MAY RE-
SULT. If the gauge begins to return to nor-
mal opera ng vacuum, then the pump is
working properly and the source of the
leak is somewhere in your sap lines or taps.
If, on the other hand, the pump fails to
recover normal vacuum, then the pump is
the source of the problem, and you should
inspect the pump diaphragms and/or
valves for any holes or tears. In the case of
the valves, check for any material that may
have entered the pump and lodged in the
valve body, preven ng the valve from
proper opening and closing.
