INSTALLATION
The Elecro SST Heat Exchanger can be installed either horizontally or vertically (please see Fig 3. And
Fig 4.).
Vertical Installation

6
Horizontal Installation
Wall Mounting
Note: Wall fixings are not supplied
The Elecro Heat Exchanger should be connected to the two independent water circuits as follows:
Connection to the secondary circuit (POOL Water)
The Heat Exchanger should be plumbed in line, after the filtration pump and filter and before any water
treatment equipment. It should be fed with clean water. Debris must 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.

7
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.
Connection to Heating or Cooling Circuit (Primary)
The Heat Exchanger should be connected directly to the primary heating circuit i.e. boiler, via the 1” BSP
male connectors, see diagram Fig 6.
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 or cooling 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 and blanking cap.
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 shouldbe installed so water flows are counter current i.e. the hot 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 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 out-put 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.

VÄGGMONTERING
OBS! Väggfästen medföljer inte
Din Elecro-värmeväxlare ska anslutas till de två oberoende vattenkretsarna enligt följande:
Anslutning till sekundär krets (POOL-vatten)
Värmeväxlaren skall monteras in-line efter cirkulationspump samt filtret och före övriga typer av
vattenbehandling.
Värmeväxlaren skall matas med rent vatten.
Värmeväxlaren skall monteras så nära värmepannan som möjligt för att minimera värmeförlusten.
Montera värmeväxlaren på den lägsta punkten för att undvika bildning av luftfickor under drift.
