8.5. Plumbing Connection

a) Leak Testing: Before commencing attachment of the pump station to the solar loop, the collector must

be plumbed to the feed and return lines and an air pressure test to 116 psi for at least 15 minutes or in line

with local codes and regulations. This is important because if there is a leak in the roof space it could cause

significant damage to the building. In addition, by doing the pressure test first, once the pump station is

then attached and fill and pressurization completed, piping on the roof and in the roof space can be ruled

out if there is any pressure drop or leaks.

b) Quick Connect: All pump stations provide 3/4” quick connect fittings both top and bottom. If you wish to

use 1/2” or 3/4” flexible stainless steel piping for the solar loop, remove the quick connect fittings and use

additional fittings as required.

c) Connection Process: Only standard hard drawn 3/4” copper pipe should be used for with quick connect

fittings. If 1/2” or 3/8” copper is being used for the solar loop use standard adapters to reduce to that

smaller pipe size.

Step 1. Mark the copper pipe 1-3/8” from end of pipe.

Step 2. De-burr the inside and outside of the pipe end to ease insertion and possible future removal.

Step 3. Push the pipe into the push fitting until you can not see the mark.

Step 4. Pull back on pipe to insure internal connection is secure.

To remove pipe from push fitting, simultaneously push the plastic ring toward fitting while pulling pipe out of

fitting.

d) Pressure Relief: The pressure relief valve is included as a safety device, designed to open at 75 psi

should the system pressure rise to that level. This may occur if for example the expansion tank is not big

enough or some blockage occurs that prevent normal operation, or extreme overheating occurs. If the

incoming main’s pressure is higher than 50 psi a pressure reduction valve must be fitted.

󱚡 WARNING

If incoming mainʼs pressure exceeds 50 psi a pressure reduction valve must be installed to

limit system pressure to no more than 50 psi.

d) Drain Pipe: The pressure relief valve drain pipe fitting is a 3/4” FPT connection. Install and tighten drain

pipe fitting with two wrenches taking special care not to stress the pressure relief valve support pipe.

e) Power Outage Drain Valve: This component is designed to allow slow flow through the collector in the

event of a power outage thus preventing freezing from occurring. It is therefore a backup to the normal

controller based freeze protection function. The Power Outage Drain Valve should be connected to a

suitable drain with the Onix pipe provided.

Step 1. Slip the ring clamp onto the Onix tubing. Press the Onix tubing onto the barbed end of the

drain valve (a little water on the barbs will help). Place ring clamp over center of barbs and release.

Step 2. Cut the Onix tubing to desired length with a sharp blade.

Step 3. Insert the other end of the Onix tubing into a drain.

8.6. Controller Connections

a) The Apricus controller comes pre-installed on the left side of the pump station.

b) Remove the controller cover by removing the screw with a small straight blade or star screwdriver. Pull

the cover straight off to expose the electrical (left) and sensor (right) terminal connections.

c) Install system temperature sensors. (See section 6.4)
