PUMP STATION INSTALLATION

SAFETY EQUIPMENT

For protection against excessive pressures in the collector loop a pressure relief valve is integrated into the solar pump station. Drain tubing must be installed in the valve outlet so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 15 feet, or use of more than two elbows can cause restriction and reduce the discharge capacity of the valve.

Do not connect tubing directly to discharge drain unless a 6” air gap is provided. To prevent bodily injury, hazard to life, or damage to property, the relief valve must be allowed to discharge fluid in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the fluid may cause property damage.

ATTENTION: TO PREVENT DAMAGE TO PROPERTY, THE LOCATION OF INSTALLATION MUST BE DRY, LOAD-CARRYING AND FROST-PROOF TO PREVENT MATERIAL DAMAGE TO THE INSTALLATION.

Mounting the solar pump station to the wall

1.Choose the position to install the solar pump station next to the storage tank (noting that the tank solar loop inlet (from collector) and outlet (to pump) are on the right side of the tank)

2.Remove the temperature gauges (C,E) by grasping the frame and pulling straight forward.

3.Remove the front cover (D) of the solar station.

4.Remove the retainer clips behind the isolation ball valves (J, Q) with a flat head screw driver to free the mounting plate from the station (see Figure 23).

Figure 23

Note: To aid in later assembly, while each leg of the station assembly is removed from the bracket, an extension leg of ¾” copper tubing can be attached to the bottom threaded connector using the ¾” female NPT sweat adaptor provided.

5.Line the mounting plate up level on the wall and mark the drill holes. (Holes will be 5 ¾” (146 mm) apart). Drill the two holes with a 3/8” drill bit and mount the plate with either the masonry mounting hardware or drywall hardware provided.

6.After the mounting plate is secured to the wall replace the solar pump station back cover, insert the retaining clips half way onto the mounting retaining stud (see Figure 24) behind the isolation ball valves (J, Q), push the assembly onto the bracket mounting stud and push the clip down into place. Ensure assembly is properly locked into place.

Figure 24

7.Connect the stainless steel corrugated hose to the safety group (N). Do not forget to insert the seal.

8.Choose the position for the expansion tank bracket on the wall beside the solar pump station. Fasten the bracket to the wall with the enclosed hardware (masonary or drywall).

9.Unscrew the tank connector to separate the two halves. The top half should be pushed onto the mounting bracket and the lock ring tightened. The bottom half should be attachet to the ¾” threads on the expansion tank.

NOTE: The tank connector allows you to isolate the expansion tank from the solar circuit (Figure 25). When the nut is unscrewed the valves in each half of the tank connector are automatically closed tightly by the integrated springs. Each side remains closed until the two halves are screwed back together and the valves are forced open.

The expansion tank should not be connected to the system until is has been flushed and charged.
