This booklet contains important safety instructions and advice on operating the appliance for best performance. Safety First – Read the instructions to ensure that you understand its operation. Always keep this booklet with the appliance for future reference.

Do not use this appliance unless it is in a level position. Level your RV before using this appliance. Gas or Electricity can be used singularly or together to heat the hot water. (GEHW). Ensure that the gas is turned on when required and start the system using the wall mounted switch. The red led will flash. The ignition cycle incorporates three cycles before lockout if the gas flame it not established. It will spark for up to 5 seconds until a flame is established or stop for another 5 seconds before repeating and once more at the end of which it will shut off and needs to be manually turned off before any further attempts could be made. This is to assist bleeding gas through when a gas bottle has been changed. The LED (Gas only) will remain on when the unit is operating. This hot water system is designed so that hot water can be extracted even before it has reached full temperature. As a rule, wait until the gas turns off automatically. It will cycle on and off depending on water usage and time. The unit will stop when the water reaches 78`C. This is then reduced in temperature using a water tempering valve for sanitary purposes.

The tank is made from stainless steel which resists corrosion with water above 60`C. This grade of stainless steel has been chosen because other materials can corrode when subjected to these higher temperatures. In Australia bore water can harbor bacteria that can eat through metals particularly in North Western Australia and across the top of Australia. DO NOT FILL YOUR TANKS DIRECTLY FROM BORE WATER THAT HAS NOT BEEN TREATED OR EXPOSED TO DIRECT SUN LIGHT FOR A NUMBER OF DAYS. The appliance is fitted with an anode to protect against bacterial corrosion. It does not need to be changed like a traditional anode because it is only there if you accidentally fill up with unsafe bore water.

This product is to be installed by an authorized person.

The Swift Hot Water System must be installed in accordance with this instruction book, all the relevant clauses of AS/NZ5601, AS/NZS3500.4, the National Installation Code for gas appliances and any other State or Regulatory requirements where applicable. Check AS/NZ 5601 for correct pipe sizing and flueing requirements.

The hot water is designed to operate at a maximum inlet pressure of 400kPa. A pressure limiting valve must be fitted in the supply line to the tank. All gas and water connections are made from the outside of the van. Refer to AS/NZ 5601 for clearances to window openings etc.

• Install in an RV or dwelling. To be installed on an exterior wall. The door must be open to the outside
• The tank must be supported to prevent movement.
• To be used with an approved two stage regulator 2.75kPa for LPG.
• All combustion air is supplied from the outside of the installation.
• Do not vent into an enclosed area.
• It is recommended to mount the appliance on the driver side of the vehicle.
• Do not modify the water heater in any way.
• Do not use a battery charger to supply power to the water heater.
• Do not Hi pot the water heater unless the electronic ignition has been disconnected

ELECTRICAL 240V AC

A switch GPO must be located in an adjacent area which is accessible when the appliance is installed. After installation leave the plug out of the GPO until hand over of the RV to the customer. If the plug is left in prior to hand over the power switch may be accidently turned on by a prospective buyer or the switch could be turned on when the vans batteries are being recharged. This will result in the element being burnt out if there is no water in the tank. Unit is supplied with a lead and needs to be hard wired. Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.

GAS CONTROL CONNECTION

The gas system is controlled by a flame monitor which lights the gas and monitors the flame. In the event of a flame failure it will automatically shut off the gas until the system is reset. There are four wires located at the bottom right corner which should be connected as follows: Red is 12V DC Positive, Black is 12V DC Negative,  Yellow is positive to LED and white is Negative to LED.

WARNING This appliance is not suitable for use as a pool heater.

The gas system is suitable for Propane or ULP

INSTALLING THE ELECTRIC STORAGE HOT WATER UNIT (MODEL EHW)

This unit is not suitable for outside installation. Position the appliance in a cupboard or under a bed where there is easy access for future service. Fix in position through the bottom flange. Provide a drain point for customer purging of the PTR valve. Install a TEE fitting in the inlet pipe with a stop cock on the outlet and connect its outlet to outside the van.

PTR Valve (500Kpa 99°C)

• Water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open  to the atmosphere.
• The pressure relief valve device is to be operated regularly to remove lime deposits and to verify that it is  not blocked.
• A discharged pipe connected to the pressure relief device is to be installed in a continuously downward direction and in frost free environment.

WARNING: The valve or drain valve outlet pipe must not be sealed or blocked.

DANGER: The operation of the thermal cut-out indicates a possibly dangerous situation. Do not reset the thermal cut-out until the water heater has been serviced by a qualified person.

DANGER: Failure t operate the relief valve easing gear at least once every six months may result in the water heater exploding.
Continuous leakage of water from the valve may indicate a problem with the water heater

If the water supply pressure exceeds the rated pressure, a pressure reducing valve is to be fitted in the installation.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified person in order to avoid a hazard.

LOCATION Choose a location to allow the body of the Hot water tank to sit on the floor of the RV with the cut out to allow the appliance to slide in from the outside. Ensure that it is clear of windows and openings into the RV and that the clearances are permitted in AS/NZ5601-2 Fit a strap or rear fixing bracket to prevent the tank moving during travel.

INSTALLING Push the unit in from the outside engaging the copper supply pipe and the hot and cold water lines through the rubber grommet. Connect the 12V DC supply with the switch provided to the positive wire. Connect the yellow and white wires to the LED mounted on the switch.

Use foam tape or other suitable flexible material to caulk around the perimeter of the body and also where the gas and water inlet are to completing the seal hole. Connect the hot water line (Red) to the top connection. The cold water line (black/blue) is connected to the lower connection. For the customer’s convenience it is recommended that a TEE fitting be placed in the inlet pipe with a stop cock so that the tank can be easily drained when the van is in storage. Extend the outlet of the PTR valve out through the bottom of the body by drilling a hole clear of any chassis rail or other obstruction and extend to a safe location. Place the two lugs on the door through the two slots in the flange of the body on the left side. The door must be screwed shut for travelling.

Carry out gas and water leak tests.

Turn on the gas supply and check the unit for correct operation as follows:

1. Fill the tank with water.
2. Turn on gas supply at bottle
3. Turn on 12V DC supply
4. Turn on isolating valve in cupboard adjacent to the water heater.
5. Turn on the gas ignition switch on the wall. Appliance will light automatically.

This Appliance is not be connected by hose set.

It is recommended that the pipes be color coded for hot and cold. I.e., Red to top hot connection and black/blue to the bottom cold connection. Bring the two pipes along the left-hand side of tank passing through the rubber grommet and then fit to 12mm swivel connectors. Ensure that the release ring is pulled away from the elbow.

GAS INPUT 7Mj. Inlet connection 5/16 tube nut (1/2UNF x 20TPI) compression 2.75kPa.

You should check your appliance to ensure that there has been no damage or movement to its installation before starting and at the completion of any trip. In any case have your appliance should be checked by a service agent as recommended by the Safety Regulators every 2 years and refer to the Swift Web site for any notices or changes that may occur from time to time. The appliance has been designed so that all water connections are on the outside of the vehicle. This means that if a leak occurs in the connections it will drain outside of the van.

When you are about to use your RV after a prolonged period check inside the cover of the appliance to ensure that it is clean and that no foreign matter has been posted into the unit through the flue outlets.

If the water has not been used in the van for some time turn on the pump and flush out the water and then replace with fresh water.

Never operate the appliance before filling the tank with water and checking that water flows from one of the hot taps. In freezing conditions check that water flows from the hot tap before turning the appliance on. Failure to ensure that the water tank is full may cause the element to burn out which would not be covered by warranty.

This appliance is fitted with a type of anode designed to protect the tank from Bacterial attack should untreated bore water enter the tank. (Search Bacterial corrosion on the internet for information regarding this). The anode does not need to be changed on a regular basis.

ROOM HEATER

The Swift Ecotherm Heater has been designed to connect to the Swift Hot Water unit so that it can utilize the heat from the tank while still giving hot water for showing or washing. There is no flue required for the heater and you have the added bonus that it can operate off the gas or the electric system. The heater increases the capacity of the hot water unit because it constantly circulates the water with in the hot water unit.

OPERATING INSTRUCTIONS

Electric Heating. Turn on the switch at the GPO. The heating element will bring the water to the preset temperature and automatically cut off. The element will them automatically switch on and off to maintain the temperature. It will reach a usable temperature in approximately 40 minutes and full temperature in 1 hour. Running both the gas and the electric at the same time will heat the water quicker.

Gas Heating. Turn on the gas switch and the LED light will flash rapidly until the gas lights. The light will then remain constant, If the gas fails to light or the gas bottle has been changed the system may have air in the line so the it is designed to repeat three times to ensure that the flame sensor monitors the gas correctly. If the gas fails or it senses a fault in the system, it will turn off the gas and the LED will flash at a constant rate until the switch is turned off to reset the unit.

Care and Maintenance When storing your van, it is recommended that you drain the tank or when you next use the van run out at least 40 liters of water to refresh the water quality. (Drain through the ball valve located in the cold line near the hot water tank. The tank is made of corrosion resistant stainless steel and it does not require an anode to prevent corrosion. There is a sacrificial tube (anode) which is there to protect against bacterial attack from some types of bore water. It only needs to be replaced if you have been running the hot water on this type of water for long periods. To replace the lower cold-water elbow must be removed and the tube pulled out.
