2. 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 Fi lexTemp ELECTRONIC TEMP CONTROL Hi E2 POOL NW TELEDYNE LAARS Figure 25 Temperature Control Panel 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 Hi E2 Page 17 GAS CONTROL KNOB SHOWN IN ON POSITION Figure 26 Gas Valve 3C Lighting and S

Before treatment its pH is typically in the 3 5 to 6 0 range Handling and disposal of condensate is not complicated but it must be done correctly to prevent problems or complaints A trap neutralizer assembly is provided with the heater to simplify installation This assembly is easily installed in the base of the heater Figure 11 illustrates its installation and the routing of drain tubes To install the condensate assembly first install the short length of 5 8 I D tubing on the barbed fitting on the bottom of the condensate collector Then drop the condensate tray into the opening in the base pan of the heater bending the 5 8 tubing as necessary to get the tube into the tray Readjust the 5 8 tubing so that its lower end is 1 4 3 8 above the bottom of the tray The tray can be positioned with the outlet fitting to the right as shown in Figure 11 or with the fitting to the left depending on the direction required for condensate disposal Connect the piece of 1 2 I D tubing to this outlet fitting and route it out of the heater through the hole in the side of the base panel This tube carries condensate to the drain If this disposal tube is routed to the left remove the plug button from the hole on the left side of the base panel and push it into the hole on the right side Connect the remaining short piece of 3 8 I D tubing to the barbed tee fitting in the tubing immediately in front of the blower Position this

6. Swimming Pool Energy Savings Tips Teledyne Laars suggests the following to help conserve fuel and minimize the cost of operating your pool heater without sacrificing comfort 1 Set the heater temperature control no higher than 78 F 26 C The American Red Cross maintains that the healthiest water temperature for swimming is 78 F 26 C is Be certain you are using an accurate pool thermometer because a variance of 4 degrees from 78 to 82 F 26 to 28 C will use as much as 40 more gas 2 Carefully monitor the water temperature of your pool in the summer time because heater usage can be reduced due to warmer air temperatures 3 Find the proper setting on the pool heater temperature control and use the TEMP LOK to discourage further adjustments 4 Setthe filter time clock to start the pump no earlier than 6 00 AM during the pool heating season This is the time when nightly heat loss stabilizes 5 Ifthe pool is only going to be used on weekends reduce the heater temperature control setting by 8 or 10 degrees during the week It should be reset to the 78 F 26 C level before expected usage keeping in mind to allow enough lead time for the water to reach the desired temperature 6 During the winter shut down the heater by following the lighting and shutdown instructions in Section 3A When on vacation for longer than a week make sure the heater is shut off at the temperature control panel 7 Where possible s
