Water system connections and priming. Connect and prime water system as follows (fig. 2-6).
(a)
Remove caps from all drain fittings (fig. 2-6) and allow any water in the system to drain, then reinstall
caps on drain fittings.
(b)
Open air temperature control access door (fig. 1-1) and open hot water tank vent valve (fig. 1-12) on
top of hot water storage tank.
(c)
Connect a source of water to water inlet fitting (fig. 2-6) using supply and drain water hose assembly
(fig. 1-16).
Caution
Be sure supply and drain water hose assembly is not kinked, collapsed, or otherwise
positioned to restrict flow of water.
(d)
Connect a water hose to cold water outlet fitting (fig. 2-6) and arrange hose to drain to a convenient
place. Place hot water valve (fig. 2-6) and cold water valve (fig. 2-6) in OFF position.
(e)
Start gas turbine engine and place 400 Hz system main contactor switch in CLOSED position. Refer
to paragraph 2-16b.
(f)
Place hot water pump and cold water pump switches on instrument panel in ON position. Refer to
paragraph 2-16g.
(g)
Place cold water valve (fig. 2-6) in ON position and observe water flow from hose attached to cold
water outlet fitting. Observe hot water priming vent (fig. 2-6) for continuous flow of water. When a continuous flow of
water is observed from cold water outlet and hot water tank priming vent (fig. 2-6), close hot water tank vent valve (fig.
1-12) and place cold water valve (fig. 2-6) in OFF position. The hot and cold water system is now fully primed.
(h)
Connect dual water hose assembly (fig. 1-16) to hot water outlet fitting (fig. 2-6) and to cold water
outlet fitting (fig. 2-6).
Note
If possible freezing conditions are anticipated, connect electrical connectors on supply and
drain water hose assembly (fig. 1-16) and dual water hose assembly (fig. 1-16) to water line
heater connectors (fig. 2-3) on electrical output connection panel. Position and protect
supply and drain and dual water hose assemblies to prevent kinks, collapse, and damage
from traffic.
(i)
Place hot water valve (fig. 2-6) and cold water valve (fig. 2-6) in OPEN position and observe that
clean water flows freely from end of dual water hose assembly. Place hot and cold water valves in OFF position and
connect dual water hose assembly to point of water use. Place hot and cold water valve in ON position. Hot and cold
water delivery may now be taken at point of use.
Note
Check all outlet valves at point of water use to insure they are closed before opening valves
on power unit. Approximately 15 minutes should elapse before attempting hot water use to
permit water to be heated.
(6)
60 Hz power output connections. Use 60 Hz electrical power output cable assembly (fig. 1-16) to connect
between the 60 Hz power output receptacle (fig. 2-3) and other elements of the MUST hospital. Two 60 Hz convenience
receptacles (fig. 2-3) are included on the electrical output connection panel to provide 60 Hz power for external
requirements. The convenience receptacles will accommodate a standard three-prong, twist lock plug.
(7)
400 Hz power output connections. Use 400 Hz electrical power output cable assembly (fig. 1-16) to
connect between the 400 Hz power output receptacle (fig. 2-8) and other elements of the MUST hospital. Two 400 Hz
convenience receptacles (fig. 2-4) are included on the electrical output connection panel to provide 400 Hz power for
external requirements. The convenience receptacles accommodate standard three-prong, twist-lock plugs or parallel U-
ground plugs.
(8)
400 Hz auxiliary power connections. If 400 Hz auxiliary power is required, connect 400 Hz electrical power
output cable assemblies (fig. 1-16) to 400 Hz auxiliary power receptacles (fig. 2-3) and to 400 Hz power requirement.
Caution
Do not use auxiliary power outlets if power unit conditioned air system is in operation or is to
be operated, as an overload condition could result.
(9)
Remote fan operation connections. If the recirculating fans in a nonoperating power unit are to be
operated, connect 400 Hz remote power cable assembly (fig. 1-16) to remote
2-9
