performed in the mechanical room. The loop should be tested to 116 psi for at least 15 minutes or in

accordance with local codes and regulations.

5.6.4. Insulation

a) Insulate Piping: Heavily insulate all piping running to and from the manifold with a high quality insulation

of at least 15mm/0.6” thickness, and double that thickness in cold climates. Heat loss from the piping can

be significant so particular attention should be taken to insulate any possible points of heat loss, particularly

on outdoor piping.

b) Seal Insulation: Ensure the insulation is tight against the manifold casing, preventing loss of heat from

the inlet and outlet. In order to prevent water from entering the temperature probe port and/or in between

the piping and insulation foam, a high quality silicone sealant should be used to form a water-tight seal.

This is also important to avoid water running down under the insulation along the copper pipe into the roof

space.

c) Protect Insulation: EPDM (foam) insulation that is exposed to direct sunlight should be protected

against UV related degradation by wrapping/covering with a suitable material such as adhesive back

aluminum foil, flexible protective paint, PVC conduit or similar. If using a “line-set,” ensure the casing is

suitably rated for outdoor use and will not be easily torn during the installation process.

d) Glass Wool Insulation: For systems designed to allow stagnation, high temperature rated insulation

such as glass wool or mineral wool should be used on piping, Supply and Return, within ~6 ft (~2 m) of the

collector. Glass wool insulation may come with an external foil wrap, but any cuts made during installation

should be sealed with watertight and UV stabilized material such as thick adhesive-backed aluminum foil or

PVC jacket.

e) Extra Insulation: All system piping, both interior and exterior, should be completely insulated. This

includes all potable piping between tanks and to the heat exchanger, as well as, the first 5 ft (1.5 m) hot

outlet piping from the tank to the taps, as this is a significant point of passive heat loss. Also, insulate any

blank ports on the tank, which will radiate heat. An additional insulation wrap around the tank can also

further reduce daily passive heat losses.

f) Roof Rats: In some regions (California in particular), rats may attack insulation, and so consideration of

this may be required. Birds have also been known to steal exposed, exterior EPDM to make nests. Refer to

local regulations and common practices to protect the insulation from attacks.

g) Public Areas: In areas of public traffic, all exposed components must be maintained under 140°F or

insulated/isolated. Adhere to local codes and regulations.

5.7 Evacuated Tube & Heat Pipe Installation

The Apricus solar collector is a simple “plug in” system. The heat pipe and evacuated tube assembly just

needs to be inserted into the manifold. The contact between the heat pipe condenser/tip and heat pipe port

in the header needs to be tight in order to ensure good heat transfer. Under normal use, once the heat

pipes are installed they should never have to be removed.

󱚡 NOTICE

Do not install the heat pipes and evacuated tubes until system plumbing is

completed, the solar loop is charged, the pump and controller are operational and

ﬂuid is currently circulating (set controller pump function to ON) unless the system

(in particular insulation) is designed to withstand high temperature stagnation or the

tubes are covered.
