PrePak units are also available without their door-mounted
Potter PFC-4410-RC Releasing/Control Panel and Air Com-
pressor. These units will still retain their Listings/Approvals,
however the installing contractor should make sure that any
remote controlled Releasing/Control Panels used with these
units are Listed/Approved and programmed to handle the
required sequence of operation necessary to operate the
automatic sprinkler system. Any unauthorized modification
or addition made on-site to a factory-built Listed/Approved
unit will void the Listing/Approval. Such modifications or
additions may void the unit’s warranty as well. Consult Re-
liable’s Technical Services Department before proceeding
with any such modifications or additions.

a minimum water supply pressure of 20 psi (1.4 bar)
and a maximum water supply pressure of 250 psi
(17.2 bar). Note: 1 bar = 100 kPa.
2. Friction loss, expressed in equivalent length of
Schedule 40 pipe and based on Hazen-Williams For-
mula is:
System Size: Equivalent Length
2” (50mm) 19.4 ft (1.3 m)
2½” (65mm) 24.5 ft (1.8 m)
3” (80mm) 28.9 ft (3.8 m)
