with the exception of an electrical power source and fuel. The electrical power required
to operate the system is 120 VAC, 60Hz, 20 amp, single phase.
The heating unit is mounted and enclosed in a steel, welded, square tubular frame,
measuring 46” x 26” x 30.5”, weighing approximately 300lbs. The submersible water
pump with a 25 foot umbilical is packed in the frame with the fuel tank.
The heating unit is designed to operate on a 120 VAC, 60Hz, 20 amp, single-phase power
source, using #1 or #2 diesel oil.
The unit is rated at 350,000 B.T.U. an hour output and is capable of heating the outlet
water to temperatures in excess of 200° F., depending on the size of the fuel nozzle used
and the inlet water temperature. The heater will maintain the set operating output
temperature to +/- 1° F. Do not heat salt water is excess of 135 degrees F for it may
crystallize inside the coils.
Fuel consumption is dependent on the size of the fuel nozzle in use. For example a 0.75
size nozzle will use approximately 3/4 gallons of fuel per hour, while a 2.0 nozzle will
use approximately 2 gallons of fuel per hour.
Inlet water is provided to the heater by means of the 11-g.p.m. positive displacement
submersible pump, provided with the system. The pump has a maximum combined
pumping-lift head capability of 600 feet at 40 psi.
The submersible pump is designed to operate from a 120 VAC, 60Hz, 15 amp, single
phase power source. A 15-amp switched outlet is mounted on the heater unit for use with
the submersible pump only.
CAUTION!
It is required that the diver uses a hot water suit liner. This will help
to eliminate hot spots which could cause burns and provide
thermal protection in case of hot water heat loss.
