Resumen del manual


3. Pipe fittings must be considered when determining gas pipe sizing. Page 6 Caution Permanent damage to the gas valve will occur if the following procedures are not followed. 8. If the gas supply pressure is less than required, check for under-sized pipe between the meter and the heater, a restrictive fitting, or an undersized gas meter. Gas supply pressures to the heater are listed in Table 4. NOTE: The maximum inlet gas pressure must not exceed the specified value. The minimum value listed is for the purpose of input adjustment. Refer to Table 4. Table 4. Gas Supply Pressure Requirements Supply Pressure Natural Gas Propane Gas Water Column in. (mm) in. (mm) Minimum 6 (152) 10 (254) Maximum 14 (356) 14 (356) 9. Before operating the heater, test the complete gas supply system and all connections for leaks using a soap solution. Do not use an open flame. Caution Some leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing. 2E-2. Special Precautions for Propane Gas (LLG Only) Liquefied petroleum (LP) gas is heavier than air. Therefore, do not install pool heaters using LP gas in pits or locations where gas might collect. Locate heaters a safe distance from LP gas storage and filling equipment. Consult local codes and fire protection authorities about specific installation restrictions. 2F. Electrical Wiring 2F-1. General Information (LLD Only) Wiring connections must be made exactly as shown in the wiring diagram found on the inside of the heater (see Figures 6 and 7 for typical examples) and must include a definite means of grounding. There is a bonding lug on the right side of the heater, where a bond wire must be attached. The heater comes factory-wired intended for use with 240 Volt, 60 Hz AC field electrical supply. To use 120 Volt, 60 Hz AC requires rewiring of the heater. This should be done by a certified electrician only, as with all wiring. To wire the heater for 120 Volt, 60 Hz AC, follow the alternate 120V wiring method depicted in Figure 6. Additionally, the ignition control module must be rewired. The wire from the terminal marked IGN/240 must be removed from that terminal and placed on the terminal marked IGN/120. Electrical wiring must be in accordance with the latest edition of the National Electric Code (NEC), ANSI/National Fire Protection Association (NFPA) 70, unless local code requirements indicate otherwise. To wire the Laars Lite heater: 1. Wire the heater to a 120V or 240V /60 Hertz (Hz) electrical source. 2. Connect the wires from the source to the leads on the right side of the heater in the space behind the ignition control (see Figure 8). 3. Remove the screw located to the lower right of the transformer and open the hinged cover. NOTE: No external junction box is required. 2F-2. Auxiliary Time Clock Wiring (LLD or LLG) If you install a time clock to control the filter pump operation, it is recommended that the time clock have its own low voltage (Fireman’s) switch to turn off the heater before turning off the pump. The switch should shut off the heater about 15 minutes before the filter pump shuts off. This will allow for a more efficient operation by removing any residual heat contained in the heat exchanger back to the pool. To install a time clock auxiliary switch into the heater wires (see Figure 9): 1. Remove heater door. 2. Remove the factory installed wire between terminals 1 and 2 on the terminal strip (see Figure 9). 3. Connect the wires from the time clock auxiliary switch to the two terminals. Use American Wire Gage (AWG) No. 14 gauge stranded copper wire with a temperature rating of 221°F (105°C) or greater. The length of the wire between the heater and the time clock should not exceed 10-15 feet (4.57 m). The contact points of the time clock switch should be silver, or a low resistance alloy. 2F-3. Remote Operation (Model LLD Only) The Laars Lite pool/spa heater controls can Model LLG & LLD Pool and Spa Heater Page 7 Figure 6. LLD Connection/Schematic Wiring Diagram. Page 8 Figure 7. LLG Connection/Schematic Wiring Diagram be wired for remote operation. The CS-02 remote control permits switching from one temperature controller to the other and turning the heater on and off from a remote location. The CS-04 includes the same features as the CS-02 plus a remote temperature controller. Contact Teledyne Laars for further information. Reference part numbers CS-02 and CS-04. An interrupt (on/off) type remote can be connected by removing the jumper wire on the terminal block located in the control compartment (see Figure 6) and connecting the two wires from the remote to the two terminals on the terminal block. This type of remote control will turn the heater on or off, but will not switch between the two temperature controllers on the Flex-Temp control panel.
