2. GENERAL INSTALLATION INSTRUCTION

2.1 Mounting instruction

The Elecro Heat Exchanger can be installed either horizontally or vertically. (Please see Figs. 3 and 4).

2.2 Flow Direction

The Elecro Heat Exchanger should be connected to the two independent water circuits as follows:

1. Connection to Water Filtration Circuit (Secondary)

The Heat Exchanger should be plumbed in-line, after the filtration pump and filter and before any water

treatment equipment. It must be fed with clean water. Weed/debris should not be allowed to enter the Heat

Exchanger. The Heat Exchanger should be installed as close as possible to the boiler to minimise heat

loss.

To assist with correct air purging and to ensure that the Heat Exchanger remains full of water during

operation, it should be installed at the lowest point in the filtration circuit.

If the Heat Exchanger is installed in a vertical plain, it is essential that the pool/pond water (secondary

circuit) enters low and exits high.

2. Connection to Heating or Cooling Circuit (Primary)

The Heat Exchanger should be connected directly to the primary heating circuit i.e. boiler via the provided

1” BSP male connectors, see diagram below.

NOTE: The circulation pump of the primary circuit should be controlled by a thermostat, which should

be connected via the filtration pump to allow heating only when the filtration pump is running.

Air bleed valves should be installed at the high points of the primary circuit. To ensure correct temperature

detection, it is essential that the thermostat / thermistor is positioned at the water inlet of the Heat

Exchanger.

NOTE: The Thermostat Control is only included with the ‘Optional’ fully equipped kit. The standard unit

is supplied only with a Thermostat pocket.

Care should be taken not to over tighten any connections, as this could result in damage to the Heat

Exchanger.

CIRCULATION DIRECTION

The primary and secondary circuits should be installed so water flows are counter current i.e. the water

from the primary circuit should flow in the opposite direction to the water in the secondary circuit.

CAUTION

If the Heat Exchanger is not used during the winter months, it must be drained to prevent frost damage.

NOTE: For Winterising / maintenance, it is recommended that the Heat Exchanger is installed with

isolation valves on both water input and output sides of the primary and secondary circuits. This

will allow the water to be shut off on both sides and aid removal from the system, when required.

3. WATER QUALITY

To prevent damage to the Heat Exchanger, the water quality must be kept within the following limits:

•Chlorine Content: Max 3mg/l (ppm)

•Chloride Content: Max 150mg/l

•PH: 6.8-8.0

•Calcium Hardness: 200-1000mg/l (ppm)

4. WARRANTY

The Elecro Heat Exchanger is guaranteed for 2 years from the date of purchase against faulty

workmanship and materials.

•The manufacturer will replace or repair, at its discretion, any faulty units or components returned

to the Company for inspection.

•Proof of purchase may be required.

•The manufacturer will not be liable in cases of incorrect installation of the Heat Exchanger

inappropriate use or neglect of the Heat Exchanger
