data supplied.
Note:
The drain collector shall be connected to an open
drain. Do not restrict or reduce drain piping.
3. Install the vacuum sprinklers piping network and
vacuum sprinklers in accordance with applicable
standards.
4. Connect alarm audible devices, where applicable,
according to electrical schematics (see field wiring
diagram in section
F
ELECTRICAL
).
5. Connect the AC power to the release control panel and
the vacuum pump on two separate breakers in the
electric distribution panel (see field wiring diagram in
section
F
ELECTRICAL
).
Notes:
AC power connections must be made by a qualified
installer according to national standards.
Do not apply AC power to the release control panel and
the vacuum pump yet.
6. Perform preliminary inspection as
outlined in
paragraph 1.2 of the current section prior to putting
system in service.

1.2 Preliminary inspection before placing the system in
service
1. Open door to mechanical section.
a) Main water supply valve
(D1)
must be
CLOSED
.
b) Priming valve
(B1)
must be
CLOSED
.
c) Flow test valve
(B6)
, main drain valve

(B5)
and alarm line drain valve
(B7)
must be
CLOSED
.
e) Manual emergency release valve
(B10)
must be
CLOSED
.
f) Vacuum supply must be

SUPPLY
).
g) Gauges
(B11 and B12)
should show 0 PSI (0 kPA).
h) The shut-off valve
(D4)
must be
OPEN
.
2. Using the built-in contractor's hydrostatic test ports (see
figure 2
DETAILED SYSTEM TRIM SCHEMATIC
of the current
section for location), fill vacuum sprinklers piping
network with water and maintain pressure as per
NFPA-13 requirements.
WARNING !
Do not subject the pressure gauges and
pressure transducer to hydrostatic pressure above 250 PSI
(1724 kPA). Close gauge valves before proceeding with
hydrostatic test.
3. Correct leaks if any before completing test.
4. Verify that main water supply valve
(D1)
is
CLOSED
.
OPEN
main drain valve
(D3)
, alarm drain valve
(B7)
and
system drain valve
(G10)
to completely drain the
vacuum sprinklers piping
.
5. Apply AC power to the release control panel and the
vacuum pump (see section
F
ELECTRICAL
).
6. Install and connect the batteries. Observe battery size
and polarity.
For battery capacity calculations, see the VIKING VFR-400

.
7. Reset the release control panel and silence the alarm.
Note:
Batteries shall be installed with the control panel at
hanged position. Battery compartment should always stay
closed while rotating the control panel.
8. The
FLX-PC
®
(G18)
VACUUM / PRESSURE CONTROLLER
should show 0 mBAR (0 kPA).
