o. Feed the heater power cord alongside of the thermostat cord and plug it into the general
purpose transformer outlet.
2. Install the plenum and ducts inside the TWPS enclosure as follows (see Figure 10):
a. Pass an 8-in. duct between the RO feed tank and the NBC filter tank. Direct the open
end to discharge at the turbocharger. Connect the other end of the duct to the top of the
main plenum.
b. Place the main plenum up to the RO feed tank frame between the RO Clean Valve V-701
and the RO feed pump discharge pipe.
c. Hang the right plenum behind the air compressor with the two straps provided. The large
duct inlet points toward the main plenum and the register points down.
d. Connect the 4-in. hot air duct to the right plenum and direct it down toward the corner by
MF filter drain valves V-203 and V-403.
e. Connect an 8-in. duct from the main plenum to the right plenum.
WARNING
Tripping hazard (A-TWPS only). After the 12-in. heater outlet duct is connected to
the main plenum, the duct becomes a possible tripping hazard when entering and
leaving the operator station area. Carefully step over the duct when entering and
leaving the operator station area. Failure to observe this warning may result in
personal injury.
