For example:
- Brass fittings
- Evacuated tube caps and clips
- Heat transfer paste
- Evacuated tubes & heat pipes
- Frame fasteners
- Sensor cables
- Ball valves, drain valves
4.2. Unpacking and Inspection
4.2.1. Evacuated Tube & Heat Pipe Inspection
a) Stock Inspection: Open the evacuated tubes boxes. Check to make sure the evacuated tubes are all
intact and the bottom of each tube is still silver colored. You may need to remove the rubber caps to do this.
If a tube has a white or clear bottom, it is damaged and should be replaced. The heat pipe should be
removed from the damaged tube and inserted into a replacement tube. Apricus installers should ALWAYS
carry spare tubes when traveling to an installation.
b) Protect Tubes: As soon as the evacuated tubes are removed from the box, put on the rubber tube caps,
if they are not already on the tubes they will be located in the manifold box. These caps protect the bottom
tip of the glass tube from being broken if knocked.
c) Copper Heat Pipe Color: Heat pipes are bright and shiny when newly manufactured, but will dull and
may form dark-grey surface discoloration over time. This is due to mild surface oxidation and is perfectly
normal and does not affect the integrity of the heat pipe or performance.
d) Shield from Sunlight: Do not remove the tubes from the box and/or expose the tubes to sunlight until
ready to install, otherwise the heat pipe tip will become hot enough to cause serious skin burns. The outer
glass surface should not become hot. If it does feel hot, the tube has lost vacuum and should be replaced.
Wear safety glasses and leather gloves at all times when handling evacuated tubes and
heat pipes. Never touch the inside of evacuated tubes or the heat pipe tip after exposure to
sunlight.
✖ Damage to collectors and other components incurred during transport is not eligible for warranty claims.
4.2.2. Frame
a) Unpack Manifold: Unpack the standard frame that is provided together with the manifold. If a frame kit is
being used, those components will be packed separately from the manifold and standard frame kit. See
Appendix 1 for standard frame diagram.
b) Attachment Roof Mounts: Depending on the roof surface and attachment method, rubber pads, track
feet, U-feet or round feet may be used to attach the standard frame to the roof. These components are
supplied separately from the standard frame.
c) Assemble Frame: Assembly of frame is best completed on the ground on a clear flat area. Assembling
on the roof is both dangerous and makes it easy to lose bolts and nuts that may roll away. The collector
frames are relatively light and can easily be carried onto the roof once assembled.
4.2.3. Balance of System Components
a) In addition to the solar collector, storage tank, pump/pump station and controller you may also need the
following components:
• Expansion tank (for cold water inlet and/or closed loop systems)
