These instructions must be provided to the use after installation. OPERATING INSTRUCTIONS SAFETY FIRST - To reduce the risk of injury: The water in a tub or pool should not exceed 40°C (140°F). A maximum water temperature in excess of 40°C is not considered to be safe for all persons. Lower water temperatures are recommended for extended use (exceeding 10-15 minutes) and for young children. WARNING do not fill bathtub with water warmer than 40°C. This is a health hazard and may cause the heaters reset button to trip, which can only be reset manually (see HIGHLIMIT PROTECTION). Prolonged immersions in warm water may induce hyperthermia. The causes, symptoms and effects of hyperthermia may be described as follows: Hyperthermia occurs when the internal temperature of a body reaches level several degrees above the normal body temperature of 37°C (98.6°F). The symptoms of hyperthermia include an increase in the internal temperature of the body, dizziness, lethargy, drowsiness and fainting. The effects of hyperthermia include:
WARNING - The use of alcohol, drugs or medication can greatly increase the risk of fatal hyperthermia.
INITIAL TESTING OF THE TEMPERATURE SETTING Mercury heaters are equipped with limiting thermostats to protect the use against the hazards of excessive heat including hyperthermia. However, the user should check the proper functioning of the heater after installation, before the first use to ensure a safe operation. Check by filling the tub to the appropriate level and turn the system on. Let the system run with the heater on until the temperature stabilizes at a maximum level and the indicator light goes off. Measure the water temperature with an accurate thermometer. Water temperature should be 40°C (140°F). However, since the water temperature regulating devices may have a tolerance, your measured temperature may be slightly lower of higher than the preset 40°C (140°F) level. If the variance is more than +3°C (+5°F), contact your supplier for remedy. NORMAL OPERATION The operation of the Mercury heater is fully automatic. When installed properly it will turn ON when the system is turned ON and OFF when the system is turned OFF. The internal thermostat of the heater ensures that the water temperature is maintained at the present level for as long as the system is ON. There is no separate heater control operated by the user. HEATING RATE: The 23 Ov, 2000W Mercury heater is designed to efficiently maintain the water temperature of a standard bath tub at the present level for 40°C (140°F). However, if starting with cold water the Mercury heater will increase the temperature at a rate of 6°C to 8°C (11°F to 14°F per hour depending on the initial water temperature the room temperature and the size of the bathtub. INDICATOR LIGHT: When initially turned ON the Mercury heater stays ON until the temperature reaches the preset temperature, then it will turn OFF automatically. It will stay OFF until the temperature drops a few degrees below the preset value, and then it will turn back ON. The heater continues this ON/OFF cycle for as long as the pump is ON. The indicator light on the top panel will indicate the heaters ON position. HIGH LIMIT PROTECTION/RESET BUTTON: In addition to the regulating thermostat, the Mercury is provided with a manual reset High Limit thermostat to protect the use against the hazards of high temperatures. In the event of water or the heater enclosure reaching temperatures of higher than 49°C (120°F), the High Limit thermostat will trip (interrupt power), hi order to reset, let the water cool down to approximately 38°C (100°F), then simply push the reset button on the top panel. The heater should resume operation in the normal manner. DRY RUN PROTECTION: The Mercury heater is equipped with a pressure sensing Switch that protects the heater against the hazard of running the system without water. If the water level is low at the beginning or drops low during the operation the pressure sensing switch will attempt to interrupt the power. Heater can only come ON when the water is at the appropriate level and the pump is running.
INSTALLATION INSTRUCTIONS: Important: Mercury heater shall be installed in accordance with the Article 680 of the national electricity code, ANSI/NFPA-70, and with requirements of the authority having jurisdiction. Water shut-off or check valves must not be installed in piping from the outlet of the heater to the whirlpool or tub. Install to permit access for servicing. PHYSICAL INSTALLATION WARNING: Under no circumstances should any of the outlet (side) ports be closed. Water must flow through both ports when the heater is on. Heater MUST be installed in the pressure (discharge) line of the pump. This can be accomplished in either of the following methods. NORMAL (RECOMMENDED) "T" INSTALLATION METHOD This method utilizes full capabilities of the heater by allowing maximum flow through all heater ports. In addition, due to the way the heater is installed the hazard of water retention in the heater is eliminated. Ensure all 3 flat gaskets are inside the three union nuts. Install the heater directly above the HyFlo pump, by connecting the middle inlet heater port to the pump discharge. Hand tightens only. Connect the outlet (side) ports of the heater to the pipes feeding the jets on both sides of the tub using the provided fittings. Hand-tighten only. Ensure that a minimum length of 610mm (2 feet) of piping is maintained between the heater and any opening to the tub.
INLINE INSTALLATION METHOD This method is for applications where, due to the nature of the pump, plumbing or space restrictions, the "T" method is not possible. In the inline installation method, the middle heater port is closed to allow a straight water path between the two side ports. Ensure that all 3 union nut flat gaskets are in place. Cap and seal the middle port of the heater using hydrabaths fitting 701123 and 1-inch plug 400008. Install the heater onto the pressure (discharge) line of the pump using the provided fittings. To provide for proper drainage, ensure the heater is installed only with the indicator light on the right label facing out. Ensure that a minimum of 610mm (2 feet) of piping is maintained between the heater and any opening to the tub.
ELECTRICAL INSTALLATION WARNING - When using electrical products basic precautions should always be followed, including the following: All electrical connections must be performed by a qualified electrician in compliance with all applicable national and local codes. DANGER: RISK OF ELECTRICAL SHOCK Connect Only to a circuit protected by a Ground-Fault Circuit-Interrupter (GFCI) CAUTION: To prevent the risk of electrocution, check heater for proper ground connection. The heater must be properly grounded with a conductor equal to or greater than the power supply conductors. CAUTION: Before making any electrical connection or during installation and service make certain that the electrical power is turned off at the source or circuit breaker and take measures that it CANNOT accidentally be turned on again. POWER SUPPLY: Provide separate branch circuits for pump and heater. Refer to pump's label and instructions for choosing the appropriate power supple for the pump. Provide a 230V. 10A, and 3 wires with grounding branch circuit to a suitable junction box near the heater. Connect the heater wires in the junction box appropriately. Use suitable strain reliefs to protect the wires injunction box. BONDING: Install bonding wire (supplied with heater) to bonding connector on pump motor. Continue to a suitable in ground terminal or other metallic enclosure(s), if provided in the vicinity of the heater, using an appropriate bonding conductor. CONTROLS: In standard installations a pneumatic switch or timer controls the pump. There is no need to install a separate control for the heater. The heater is equipped with a pressure-sensing switch that will turn the heater ON automatically when the pump is turned ON and the water is flowing. For additional control, the heater may be provided with separate switching options. However, all such additions must be approved by HydraBaths and the Listing authority of complete systems.
