The backpulse tank has been pre-pressurized to
approximately 30-35 psi from the factory. Conrm the
backpulse tank pressure. If the backpulse tank pressure is less
than 30 psi, add air using a pump. Recheck the pressure after
15 minutes to ensure that there are no leaks in the backpulse
tank.

WARNING: Be sure to always verify
and set backpulse tank pressure. Homespring must be
empty when checking pressures.

The pressure may require adjustment depending on the
water system of the home. Refer to the table below to ensure
proper tank pressure. Air can be added or released from the
air bladder valve as required. Backpulse tank pressure should
be set approximately 5 psi below inlet pressure.
Application/Pump Set-points Backpulse Tank
Pressure
Municipal 30-35 psi (207 kPa)
Pump (20 psi low - 40 psi high) 20 psi (140 kPa)
Pump (30 psi low - 50 psi high) 30 psi (207 kPa)
Pump (40 psi low - 60 psi high) 30-35 psi (207 kPa)
WARNING: Do not pressurize the
backpulse tank to greater than 35 psi. Higher pressures
may cause the tank's bladder to burst, leading to
ineective daily cleaning. Ineective cleaning can
greatly reduce the life of the system, leading to
personal injury, illness, and/or death.
Once the backpulse tank pressure is checked, adjusted, and
set, record nal pressure on the service tag and on Page 3 of
this Manual.
Pipe Assembly and Installation
Ensure that all threaded connections are tted with NSF
approved plumber tape or pipe dope (for potable water) to
prevent leakage.
For systems being installed on surface water applications, the
surface water kit must be installed.

Turn o water supply where the water enters the home.
Plumb the inlet pipe at approximately 48" (122 cm) away and
the outlet pipe at approximately 20" (50 cm) away from the
end cast iron stand. Install water shut-o valves on the new
plumbing. The terminal ends of the new plumbing must be a
3/4" MNPT adapter in order to use the supplied stainless steel
ex hoses.

Right-pointing system conguration is shown in Figure 43.
For left-pointing system conguration, reverse the horizontal
orientation shown in Figure 43.
NOTE: The water bypass in the gure only bypasses the
system. This conguration may be required according to the
local code in your area.
