Installation – storage tank
and solar controller
Connecting the temperature sensor at the storage tank
The short tank sensor from the solar controller goes inside
the sensor pocket located at the “flow” connection near
the bottom of the storage tank. When inserting the sensor
into the pocket, ensure that it is inserted all the way into the
pocket and reaches the end. Install the sensor pocket plug
and fix the clamp to the sensor pocket using the screws
provided. This will prevent the temperature sensor from
being pulled out of the sensor pocket and seals it from the
outside environment.
FLOW
Filling the storage tank
Once all plumbing has been completed, it is necessary to fill
the storage tank with water in order to allow the hot water
system to be electrically tested. Open the isolation valve on
the inlet piping and activate the temperature and pressure
relief valve on the tank.

Once water begins flowing from the relief valve piping de-
activate the lever on the temperature and pressure relief
valve. Close the isolation valve on the inlet piping and repair
any leaks as necessary.
Installation - temperature sensor
The solar controller has two temperature sensors that
are required to be installed. One sensor will measure the
temperature of the water at the collector array. The other
sensor will measure the temperature of the water at the
bottom of the storage tank. Both temperature sensors
should not be run alongside power supply cables as this may
induce a false signal into the sensor cable.
Installing the collector array temperature sensor
The collector sensor cable is provided in the kit KKSSURA
and is 15m long. It has a temperature sensor on one end
that is required to be installed in the sensor pocket located
on the outlet to the collector array, and the connector at
the other end inserts into the plug at the solar controller.
It is recommended that this sensor cable be tied neatly to
the insulated pipe work between the storage tank and the
collector array. Any excess cable should be tied neatly in a
loop and kept out of the way. If it is possible that the sensor
cable could become damaged during the life of the hot
water system it is recommended that the sensor cable be
protected by installation in a conduit or by other protective
means. If the solar hot water system has evacuated tube
collector(s), the temperature sensor is to be installed in the
sensor pocket on the side of the collector near the outlet
pipe connections to the collector array. The sensor shall be
inserted all the way in and sealed with silicon to protect it
from the environment and hold it in place.
If the solar hot water system has flat panel collector(s), the
temperature sensor is to be installed in the sensor pocket on
the outlet connection of the collector array. When inserting
the sensor into the pocket, ensure that it is inserted all the
way into the pocket and reaches the end. Install the sensor
pocket plug and fix the clamp to the sensor pocket using the
screws provided. This will prevent the temperature sensor
from being pulled out of the sensor pocket and seals it from
the outside environment.
