Monkey Heater Specifications
The Monkey Hot Water Heater System is a complete, lightweight, portable, diver’s water heating system. The system uses a positive displacement submersible pump to provide water to the inlet side of the heater during operations. The system comes ready to operate 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.
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.
Recommended Suit Injection Temperature
2 G.P.M. Flow Rate
For depths of 0 to 100 feet:
Water Temperature to 50° F. = 96° – 98° F.
Water Temperature to 30° F. = 100° – 102° F.
For Depths of 100 to 240 feet.
Water Temperature to 50° F. = 100° – 103° F.
Water Temperature to 30° F. = 103° – 105° F.
The recommended injection temperature is a base line and will need to be adjusted depending on the following factors.
a. Flow Rate (g.p.m.) to the diver. (Higher the rate, lower the temperature.)
The minimum recommended flow rate for 1/2 ID hose is 2 g.p.m. For 5/8” and 3/4” ID hose, the minimum recommended flow rate is 4 g.p.m.
b. Heat Loss from hot water hose.
The heat loss is dependent on: ID and OD of hose, length of hose, ambient air and water, and length of hose in the water.
c. Ambient water temperature.
d. Breathing medium.
e. Breathing gas temperature.
f. Physical condition of diver.
g. Work diver is performing
Hot Water Hose Heat Loss
On an average, the heat loss for a 300 foot, 1/2” ID, 1¼” OD hot water hose with an injection water temperature of 110° F. and a flow rate of 2 g.p.m., in an ambient water temperature of 35° F., will be about 18° F. (Base Line). The heat loss for a 1/2 ID, 7/8” OD hose, will be about 36° F. (Base Line).
Heat loss for the 5/8” and 3/4” ID hot water hose, under the same conditions, will be about 12° F. (Base Line).
If the flow rate is increased by 2 g.p.m., the heat loss will decrease by about 4° F. from the above base line temperature loss.
As the ambient water temperature increases, the heat loss will decrease. The percent of decreased heat loss to water temperature is 40° = 94%, 50° = 86%, 60° = 65%, and 70° = 40%.
To figure the heat loss for a dive in 50° ambient water using 1/2” x 7/8” hot water hose, with a flow rate of 4 g.p.m.:
36° – 4° = 32° x 86% = 27.5° F. heat loss.
To figure what the heater output should be set at, add the recommended suit injection temperature and the hot water heat loss.
These figures are based on extreme ambient weather conditions. If the ambient air is warm, then heat loss will be less and heater output should be decreased.
Subtract input water temperature from the final recommended heater output temperature, multiply by the gallons per minute output, multiply by 510 (salt water) or 495 (fresh water), and divide by 100,000. Use the next smaller nozzle if answer does not come out to a nozzle size in the spare parts kit.
PUMP SET UP (Before Set-Up Procedures)
1. Remove pump from case.
2. Inspect the water tight electrical connection at the pump and the power cord for damage. If damage is evident, have a qualified electrician repair it before use.
DO NOT OPERATE ANY ELECTRICAL COMPONENT IN THIS SYSTEM WITHOUT USING A GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
3. It is recommended that the pump is operated at a depth of 3 to 5 feet below Mean Low Water (MLW) or 2 feet from the bottom to prevent pump clogging.
DO NOT OPERATE PUMP IN THE VICINITY OF WORK LOCATION IF PUMPING CONCRETE OR OTHER HAZARDOUS MATERIALS ARE PRESENT IN THE WATER. SUCH MATERIALS CAN DAMAGE THE PUMP AND HEATER SYSTEM AND CAUSE SEVERE BURNS AND SKIN IRRITATIONS TO THE DIVER.
ALWAYS DISCONNECT THE PUMP FROM THE POWER SUPPLY BEFORE SET UP OR REMOVAL FROM THE WATER.
1. Set up the unit in the are to be used.
2. Pump must be plugged into the outlet provided on the unit, for the unit to function correctly.
3. Make all of the necessary connections.
a. Water from the submersible pump or other external source.
1. If external source is used, electric valve must be installed at the unit intake and connected to the power outlet provided. (Electric Valve must fail closed.)
b. Connect hose(s) from heater outlet valve(s).
DO NOT OPERATE ANY ELECTRICAL COMPONENT IN THIS SYSTEM WITHOUT USING A GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
c. Electrical connections from a portable generator, 3kw minimum output or any other 120 VAC, 20 amp electrical source. The 15 amp electrical outlet provided on the back circuit panel box is for use with the submersible pump. ( 5kw generator is recommended.)
4. Fuel unit with either #1 or #2 diesel oil.
5. Make sure a flow of water is present through the system.
NEVER OPERATE THE FUEL PRESSURE AT THE REGULATOR LESS THAN 100 PSI. FAILURE TO OBSERVE THIS WARNING WILL RESULT IN INCOMPLETE COMBUSTION, CAUSING EXCESSIVE COIL SOOTING, HARMFUL VAPORS, EXCESSIVE SMOKE AND POSSIBLE FLASHING.
6. Turn unit on, check to make sure burner has fired, and temperature display is functioning.
a. Test flow switch.
b. To properly test flow switch function, shut down the water flow to the heater. The unit should shut down if the switch is functioning properly.
Once burner has fired, observe smoke color. If smoke is white, slightly close vent opening on the burner assembly until smoke disappears. If smoke is black, reverse procedure, slightly opening vent until smoke disappears.
7. Crack open by-pass valve. Set the water flow pressure at 10 psi., using the valve at the units water inlet.
8. Set fuel pressure at the fuel regulator to 120 psi.
9. Allow unit to run 5 minutes or until temperature remains constant on the digital display.
Starting operating temperature is recommended to beat 100° F. and is only a guideline for starting procedure. Fine-tuning of the temperature will be when in actual use. It can be set or changed using the water flow controls or the fuel pressure, set at the regulator.
DO NOT OPERATE THE SYSTEM WITHOUT A DIVER BY-PASS VALVE THAT CAN BE OPERATED BY THE DIVER TO ELIMINATE WATER FLOW IF NECESSARY. IN THE EVENT OF A UNIT MALFUNCTION, SEVERE BURNS MAY OCCUR.
10. Once a comfortable working temperature has been achieved, fine adjustments can be made at the fuel pressure regulator.
11. If all set-up procedures have been followed, you should be able to maintain your operating temperature at +/- 1° F.
A SCALD SAFE® VALVE IS HIGHLY RECOMMENDED TO BE INSTALLED AT THE DIVERS END, IMMEDIATELY BEFORE THE DUMP VALVE, AS A SECONDARY LINE OF DEFENSE AGAINST SCALDING.
HIGH-POINT TEMPERATURE CUT-OFF
After temperature has remained constant on the digital display for 3 minutes, depress the set point button on the control panel. This changes the display to read the present high-point temperature cutoff temperature. Adjustments can be made as follows:
For the primary digital readout
A. Press the center button and release. The display will read SP, wait approximately two seconds, press the up or down button and the set points will be displayed.
B. Press and hold the up or down button until the desired set point is displayed.
3 degrees F over the working temperature is recommended.
C. Wait approximately 10 seconds. If the set pint was changed, the display will flash then the SPC will return to display the sensor temperature. (If you do not want to wait 10 seconds, press the center button once to adjust the differential or press the center button twice to immediately display the sensor temperature.)
For your added safety C.D.F. has installed a Secondary High Limit Circuit. This circuit will trip the unit, the pump receptacle, and stop water flow through the unit in the event of a secondary high-limit trip.
IF THE SECONDARY HIGH LIMIT CIRCUIT TRIPS THE WATER TEMPERATURE IN THE SYSTEM MUST DROP 15 DEGREES F BEFORE THE SYSTEM WILL RESTART
The secondary high limit should be calibrated with the primary at the beginning of each dive day or at each time the unit is restarted. Follow the operations manual start up procedures as always and follow these additional steps:
A. After a constant divers working temperature has been achieved set the primary high-limit as described in the manual.
B. Set the secondary high-limit in the same manner as the primary, changing the set point temperature to 5 degrees F over the working temperature instead of 3 degrees F.
C. Complete the remaining daily safety systems checkout as described in this operations manual.
SUPPLY PUMP MUST BE CONNECTED TO THE OUTLET PROVIDED ON THE UNIT FOR THE SECONDARY HIGH
LIMIT TO FUNCTION CORRECTLY.
HIGH-POINT CUT-OFF TEMPERATURE SHOULD BE SET NO HIGHER THAN 2°- 3° F. MAXIMUM OVER WORKING TEMPERATURE TO PREVENT INJURY TO THE DIVER. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN HEAT EXHAUSTION OR SEVERE BURNS TO THE DIVER.
ALWAYS KEEP CONTROL PANEL COVER CLOSED DURING INCLEMENT WEATHER TO PREVENT DAMAGE TO ELECTRICAL COMPONENTS IN THE SYSTEM.
SHOCK HAZARD! DO NOT TOUCH ANY ELECTRICAL COMPONENTS IN THIS SYSTEM WHEN WET. SEVERE SHOCK OR ELECTROCUTION COULD OCCUR.
COMBUSTIBLE MATERIAL PRESENT. KEEP AWAY FROM SPARK OR OPEN FLAME.
