COLD WEATHER SET-UP OPERATION UNDER UNUSUAL CONDITIONS
DIESEL HEATER DEPLOYMENT
1. Set up the diesel fuel fired heater as follows (see Figure 10):
WARNING
Fire hazard. Parts of the heater can get hot enough during operation to cause
combustible materials to burn. Keep the heater at least 4 ft. away from the winter
cover (or fabric wall) or any other combustible materials. Failure to observe this
warning may result in severe injury or death and equipment damage or
destruction.
Fire and explosion hazard. Use only DF2, DL2, or JP-8 in the heater. Never burn
gasoline, naphtha, paint thinners, alcohol or other volatile fuels. Failure to observe
this warning may result in fire, explosion, serious injury, or death.
Fire and explosion hazard. Do not fill the fuel tank or move the heater while it is
on. Only fill the fuel tank or move the heater when the heater is shut off. Failure to
observe this warning may result in fire, explosion, serious injury, or death.
Suffocation hazard. If this heater is ever used inside an enclosure, exhaust gases
from the exhaust stack must be vented vertically to the outside in order to prevent
carbon monoxide (CO) build-up inside. Failure to observe this warning may result
in carbon monoxide poisoning, loss of consciousness, brain damage, and death.
a. Position the diesel heater outside the winter cover (MC-TWPS) or the fabric wall (A-
TWPS) in front of the TWPS as shown in Figure 10. The controls face the TWPS. Keep
the diesel heater at least 4 ft. away from the cover / wall or other combustible materials.
b. Remove the storage cap from the diesel heater inlet duct adapter.
c. Install the stack extension in the heater exhaust stack.
d. Attach the 12-in. air return duct to the heater inlet duct adapter (left end in Figure 10).
e. A-TWPS only. Remove the return air cover plate from the left front flat rack panel and
install the return air connector assembly.
f. MC-TWPS only. Hang the return air adapter on the TWPS frame inside the winter cover
return air sleeve.
g. Attach the 12-in. air return duct to the return air adapter / connector assembly.
h. Attach the 12-in. air outlet duct to the heater outlet duct adapter (right end in Figure 10).
i. Insert the other end of the outlet duct through the front of the winter cover / fabric wall.
j. Make sure the ducts are free of obstructions and sharp bends.
k. Hang the thermostat from one of the lower product hose clamps at a 3-way valve
opposite the Operator Control Panel. Feed the cord under the front of the RO Feed Tank
and out through the air duct opening in the cover / wall. Then plug the remote thermostat
connector into the thermostat receptacle on the heater electrical panel.
l. Make sure the power switch on the heater electrical panel is in the OFF position.
m. Hang the general purpose transformer on the TWPS frame next to the eye wash station
with the transformer facing into the equipment area.
n. Feed the transformer power cord under the RO feed tank and plug it into the cannon plug
outlet at the right side of the power distribution panel (PDP).
