Collector Return Line Connection
Final connection is achieved by welding (where solder is permitted, the
melting temperature must be greater than 220ºC) a “remote connection
pipe” to the insulated copper pipe returning to the POWER
PAK
system.
The remote connection pipe is then inserted into the top collector fitting of
the right hand collector. The connector is secured to the collector fitting
using a standard gland nut supplied with the connector. Refer to the
Collector Installation Diagram
Collector Flow Line Connection
Final connection is achieved by welding (where solder is permitted, the
melting temperature must be greater than 220ºC) a “remote connection
pipe” to the insulated copper pipe rising from the POWER
PAK
system. The
remote connection pipe is then inserted into the bottom collector fitting of
the left hand collector. The connector is secured to the collector fitting using
a standard gland nut supplied with the connector. Refer to the Collector
Installation Diagram
Collector To POWER
PAK
Connections
Pipework
Insulated copper DN15 (or nearest local equivalent) flow and return lines must be installed from the collector
array to the POWER
PAK
location.
During installation it is very important to install a constant fall of at least
5º back to the POWER
PAK
on both flow and return lines
. If these lines are taken through the roof material,
suitable flashing procedures in line with local approval practice should be employed.
Collector Temperature Sensor Lead
Install a 2 core, 0.75 mm
2
Figure 8 cable between the temperature sensor in the collector array and the
POWER
PAK
.

MODULE INSTALLATION
Collector (Primary) Circuit Connection
The flow and return lines from the collector array
are connected to brass conetite sockets located
on the top left side of the
POWER
PAK
as shown.
POWER
PAK
To Storage Hot Water System Inter Connection
Pipework
Install two insulated DN15 copper flow and return lines from the POWER
PAK
to the storage hot water system.
To minimise heat losses the POWER
PAK
should be located as close as possible to the hot water storage
system.
The location of the connections to the hot water storage system must be determined by the supplier of the
storage system. Any water storage tank connected to the potable water connections on the POWER
PAK
must
be protected with the appropriate valves and safety devices with a maximum setting of 1000kPa and 99°C.

Important: If the water quality is poor or the mineral content high, a filter and/or water
conditioner must be installed on potable water line to the PowerPAK.
