After the tank is refilled, the appliance must be re-started according to the instructions located on the inside of the door. 3A. Start-Up Procedure With any new pool or spa installation, run the filter pump with the heater off long enough to completely clean the water. This removes any installation residue from the water. Clean the filter at Figure 24. Temperature Rise Measurement at Return Header. the end of this operation before starting the heater. Do not operate the heater unless the pool is properly filled with water. When raising the temperature of water in a cold pool, remove all time clock settings. This lets the filter system and heater operate continuously until the water reaches the temperature setting on the thermostat. When that happens, the heater will shut off automatically, but the filter pump will keep running. Caution Keep all objects off the top of the heater, and do not obstruct louvre openings in heater sides. Blocking ventilation air flow may damage the heater and void the warranty. 3B. Temperature Controls The Hi-E2 heater has a dual temperature control which allows either of two different temperature settings to be selected with the rotary switch on the control panel. The owner can set one control for normal use and the other for standby, or one might be set for a pool and the other for a spa. Setting the rotary switch to the middle position turns the heater off (see Figure 25). The temperature controls on the Hi-E2 cover a range from approximately 70°F (21°C) to approximately 104°F (40°C). Always use an accurate pool thermometer to test the pool water temperature. Once the correct position for the control knob is determined, use the TEMP-LOK to keep it from going any higher by positioning the tab next to the knob and then tightening the screw. Note that the heater should not be used to maintain pool or spa temperature below 70°F. IMPORTANT: The temperature controls cannot be calibrated in the field. If the temperature control does not work, shut down the heater and replace the temperature control. DO NOT use the temperature control to shut the heater off. Remove the access door and turn the main gas valve to OFF. Figure 25. Temperature Control Panel. Hi-E2 Page 17 Figure 26. Gas Valve. GAS CONTROL KNOB SHOWN IN “ON” POSITION 3C. Lighting and Shutdown 3C-1. Lighting the Heater Lighting and shutdown instructions are listed on the label attached to the inside of the service door and also on the inside of the control compartment door. Lighting instructions are as follows: 1. Turn off all electrical power to the heater at the main junction box. 2. Open the control compartment door and turn the gas valve to OFF. 3. Turn the rotary switch on the temperature control panel to OFF. 4. Wait 5 minutes before trying to start the heater. 5. Turn the gas valve control knob counterclockwise to ON (see Figure 26). 6. Replace the control compartment door. 7. Turn on electrical power to the heater. 8. Turn on the filter pump. 9. Turn the rotary switch to either SPA or POOL. Set the temperature control to the desired setting. The ignition control automatically lights the burner when the thermostat calls for heat. 10. Set the time clock, if one is installed. 3C-2. Shutdown Complete shutdown instructions are as follows: 1. Set both temperature controls to the lowest setting. 2. Turn the rotary switch on the control panel to OFF. 3. Turn off all electrical power to the heater at the main junction box. 4. Open the control compartment door and turn the gas valve knob clockwise to OFF. 5. Turn external gas valve off. 3D. Water Chemistry 3D-1. Pools The mineral content of swimming pool water increases daily, due to natural evaporation and the addition of sanitizing chemicals. If the mineral concentration in the pool gets too high, the excess minerals will deposit on the walls of the pool, in the filter system, and in the heater tubes. It is important to keep the pH factor of the pool water between 7.4 and 7.6. See Table 7 for guidelines on other chemical measurements. 3D-2. Spas The proper chemical balance in spa water is more critical than in a swimming pool heater operation. Due to the spa's size, high water temperature, and heavy usage, chemical values in a spa can vary greatly. This chemical imbalance can result in unsanitary water conditions, and affect the life of the heater. 3D-2a. Spa Water Chemistry Maintaining safe water conditions in a spa can only be done by regular water changes and the proper addition of sanitizing chemicals. Kits are available from your local pool supply dealer for making the various tests for mineral content. One of these kits will detect copper in the system. This is usually a warning that corrosion is taking place, possibly due to a low pH value combined with other chemistry problems. The condition can be corrected by changing the spa water and closely monitoring the pH factor and chemical properties of the water (see Table 7). Test Recommended Level* Free Chlorine or Total...
