SolaStat-Eco Mounting.

Where to mount the SolaStat-Eco.

1.
Against a flat vertical surface with sufficient strength to hold the enclosure and any additional
weight from the plugs, sockets and cables.
2.
Power leads must be facing directly down, not sideways or up.
3.
Safe for users to inspect.
4.
The buttons can be easily read and accessed.
5.
Allow for cable runs, location of power outlets and lengths of wires.

Mounting the SolaStat-Eco.

1.
There is no need to open the enclosure during a standard installation.
2.
Allow for the enclosure dropping 5mm from screw centres once mounted (keyhole mounting
system).
3.
Place drill guide template against wall, checking for level alignment. 4 screws are supplied, 2
are chip board screws and 2 are combination Gib/ wood screws. It is recommended that all
4 mounting holes are used with at least 2 firmly secured into wood. The outer plastic Gib
anchors will self tap into Gib board and their inner metal screws fix into the centre of the
plastic anchors.
4.
Mark and drill/ screw as appropriate leaving the heads of the screws above the surface by
approximately 3mm.
5.
Place unit over the 4 screw heads, unit should slide down 5mm into the 'key' slots and
become secured to the wall. You will need to adjust screw height to obtain a secure fit.

Mounting the Sensors.

This is Critical to the Success of the Installation.
The sensors are the only way the SolaStat-Eco can efficiently control and protect the system.
1.
The 10m ROOF Sensor.
The 'ROOF' sensor is best fitted into a metal immersion 'pocket' just inside the solar collector
in the hot water outlet pipe. Liberally apply heat transfer compound between the sensor and
the lining of the 'pocket'. Sensor should be sealed with neutral cure sealant and externally
lagged, also the cable should be insulated from the bare pipe. Heat transfer compound is
available from your distributor or SolaStat ltd.
2.
The 2m INLET Sensor.
If Topout is required; The 'INLET' sensor is best fitted into a metal immersion 'pocket' near
the middle of the hot water tank. Caution should be exercised to allow for stratification of hot
water in the tank. For Topout Adjustable Value we recommend a conservative value somewhat
lower than the hot water tank manufacturers maximum temperature. If Topout is not required
then the 'INLET' sensor is best fitted into a metal immersion 'pocket' near the bottom of the
hot water tank. Liberally apply heat transfer compound between the sensor and the lining of
the pocket'. If a 'pocket' is not available then bond the sensor against the metal wall of the
tank (not the outside cladding or insulation) using thermal transfer compound between the
tank and sensor.
Warning.
1.
Removing or cutting the cladding may void hot water tank warrantee.
2.
Sensors must not be immersed in water.
3.
It is recommended that sensor leads be kept 300mm away from mains and comms cables.
4.
Ensure the correct sensors are mounted in the correct place.
5.
Failure to properly mount the 'Inlet' sensor as prescribed in the method above can result in;
a.
The system may not operate at greatest efficiency.
b.
There may be inaccurate 'Topout' sensing.HWC or other components may get damaged.
6. Failure to correctly mount the 'Roof' sensor as prescribed in the method above can result in;
a.
The system may not operate at greatest efficiency.
b.
Failure to detect Frost conditions. Panel can burst.
