System Installation
It is recommended that you securely attach the system to the wall or undersink mounting space. Use a
stud finder and mount the system to studs or wood beams, not to drywall. A FS20B-3 system weighs 52
lbs. dry and can weigh as much as 70 lbs when full of water. If you mount the system to drywall tit may rip
from the wall possibly causing damage.
It is not recommended to hang the system from the pipes. During filter changes, removing and replacing
the housings will put a side load on the pipe threads and can result in leakage.
All Big Brand Water Filter FS systems have a maximum pressure rating of 90 psi and a maximum
temperature rating of 100 Degrees Fahrenheit. You must have a pressure regulator installed prior to your
filter system to prevent pressure surges. It is not uncommon for city water pressure to spike as high as
200 psi. Pressure spikes can cause the housing to burst and flood your residence/facility.
