IN-LINE+ Pool Heater Installation & Operating Manual
ENGLISH Important Notes! Thank you for purchasing the IN-LINE+ direct electric swimming pool heater manufactured in England to the highest standards. To ensure your new heater will give years of trouble free service please carefully read the following instructions. Incorrect installation will affect your warranty. Do not discard this manual, please retain for future reference. Product Overview Fig 1. www.elecro.co.
ENGLISH Positioning Your heater should be horizontally or vertically sited allowing sufficient space for pipe connections and wiring, it should be screw fixed securely to a firm base or wall. NOTE: See figure 2 for details of the foot arrangement when securing to the wall or floor. Floor mount ‘Foot position’ Fig 2. Factory set floor mount ‘Foot position’ To reset for wall mount option, undo the bolts and re-assemble in the vertical position as shown.

ENGLISH Pipe Work It is essential that the pipe work connecting to and from the heater has a minimum bore (internal diameter) of 1¼” (32mm) To assist correct air purging and to ensure the heater remains completely full of water during operation, the return pipe which carries the water back to the pool must incorporate a safety loop or ‘kick-up’ in the pipe as close as possible to the heater (see fig 4) NOTE: When coupling to a flexible pipe a safety loop can simply be created by routing the pipe up and ove

ENGLISH The flow rate of water into the heater must not exceed 17,000 litres per hour (3,740 UK gallons/hour) A higher flow rate will require the installation of a bypass to prevent damage to the heater elements. The heater will not operate unless the following minimum flow rates are achieved ie: 1,000 litres / hour (220 UK gallons/hour) for 2 ~ 6-kW heaters and 4,000 litres / hour (880 UK gallons/hour) for 9 ~ 24-kW heaters. Water Quality The water quality MUST be within the following limits: PH 6.8 - 8.
ENGLISH Digital Thermostat Controller The digital controller fitted to the In-Line + heater has been preprogrammed with all the necessary parameters to ensure reliable service & operation. Below is a key explaining the controllers buttons & LED signals however these will all be explained in detail later in this booklet. Press and hold for 2 seconds to power the control on / off. Press to increase required pool temperature. Press to decrease required pool temperature.
ENGLISH Time Switching Delay To prevent overheating of the switch components within the heater caused by frequent on and off switching (cycling), the In Line + digital controller has been pre-programmed with a time delay function. This prevents rapid fluctuations in temperature or velocity from switching the heater on and off more than once in a two minute period. The time delay mode is indicated by the flashing LED next to the word HEAT on the digital display.
ENGLISH Trouble Shooting HEATER WILL NOT SWITCH TO HEATER ’ON’ MODE In most cases this will be the result of one of the following not being met. Possible Cause 1: The set point temperature has been achieved. To confirm that the digital controller is requesting the unit to heat check that the window next to the word HEAT is illuminated. If illuminated go to step 2, if not illuminated increase the required temperature to a value higher than the current water temperature.
ENGLISH Possible Cause 3: Insufficient flow. The heater will display a ‘noFL’ alarm message in the upper (red) display window when the heater has detected that the flow rate has dropped below the minimum level or stopped completely. If using a cartridge filter: Confirm this by running the system with the cartridge removed from your pump & filter unit, this will supply the heater with the maximum flow rate your unit is capable of.
ENGLISH To avoid inaccurate results when performing this test, it is important to refrain from using other high current drawing appliances in the property (such as tumble dryer, showers, cooker etc). A large domestic pool pump of 1-horsepower will draw less than 1-kW in a one hour period. The conclusion of the test should prove that for example a 6-kW heater and a ½ horsepower pump will draw between 6.3-kW to 6.5-kW in one hour.
ENGLISH Useful advice: To reduce running costs and speed up the heating process; Insulate the pool wherever possible. A floating solar cover is an essential minimum to retain heat. RoHS Compliance Statement Elecro Engineering Limited certify that our Electric Swimming Pool Heater Range complies in accordance with RoHS Directive 2002/95/EC on the restriction of hazardous substances.
Your heater is guaranteed from the date of purchase against faulty workmanship and materials ie: 2 years guarantee for incoloy heating element products and 3 years guarantee for titanium heating element products. ENGLISH Guarantee The manufacturer will replace or repair, at it’s discretion, any faulty units or components returned to the company for inspection. Proof of purchase may be required.
