Section II. Operating instructions
3-8 Operating controls and Indicators
a.
Circuit breakers 7P8 thru 1 0P8 controlling power to four voids ventilation fans are on power panel 2 on
deckhouse starboard bulkhead forward of sliding door Figure 2-3 shows location of circuit breakers for specific
fans.
b.
Voids ventilation fans 7, 9 and 10 are controlled by electric controllers with ON/OFF toggle switches. Raise
toggle switches to start fans Lower toggle switches to stop fans. Starter/controller locations are shown In Figure
2-4.
c.
Voids ventilation fan 8 contains an electrical interlock for chlorination system and requires slightly different
procedures than for other voids ventilation fans. To start this fan, first move ON/OFF switch on top front of
controller to ON, then raise toggle switch to start fan To stop this fan, lower toggle switch and then move
controller switch to OFF This controller also contains a reset button that, when pushed, resets the internal circuit
breakers for this fan and the electrical supply for the chlorination system.
3-9 Prestart procedures
a.
Open blower inlet covers high on exterior sides of ROWPU space and secure In open position with drop chains
(Figure 3-3).
b.
Remove two large flat cover plates on louvered air intake hatches on deckhouse stem bulkhead exterior (Figure
3-1). Secure with bolts to special storage mounting brackets on either side of ventilator intakes These covers
must be removed before starting fan motors 9 and 10 and diesel generators in voids 4.
c.
Open all eight emergency ventilation shutoff valves (Figure 3-4) Six of these are on sides of ROWPU space, one
In dayroom and one mounted overhead in void 4 port. Handles should be In vertical position in deckhouse and
parallel to air duct In void 4 port Emergency ventilation shutoff valves are located in ventilation ductwork as
follows:
(1)
Void 1 dayroom near starboard bulkhead
(2) Void2 starboard ROWPU space near starboard bulkhead
(3)
Void 3 starboard same as void 2 starboard farther aft
(4)
Void 4 starboard same as void 3 starboard farther aft
(5)
Void 2 port ROWPU space near port bulkhead
(6)
Void 3 port same as void 2 port farther aft
(7)
Void 4 port same as void 3 port farther aft
(8)
Void 5 overhead In void 4 port. This is a branch from void 4 port, so closing void 4 port also shuts off air to
void 5.
