suitable capacity.

b) Pressure Setting: The expansion tank is already pre-charged to 12 psi, but should be raised to the

same pressure as the system. It is recommended that the closed loop systems be operated at 40 psi. This

pressure setting MUST be lower than the operating pressure of the main’s pressure.

c) Pressure Testing: The integrated check valve on the side of the pump station is opened when the

threaded Onix fitting is connected. System pressure tests (with air or water) should be performed before

attaching expansion tank.

d) Mounting: The expansion tank is supported using the L-shaped mounting bracket. The L-bracket is

mounted to the wall with the hardware provided in the expansion tank mounting kit.

Step 1. Mark and drill two (2) pilot holes using the mounting bracket as the guide.

Step 2. Insert the plastic hollow wall anchors into the holes, if building structural members are not

available.

Step 3. Using a Phillips head screwdriver and the appropriate screws and washers secure the pump

station to the wall.

e) Connection: The expansion tank connection is located on the lower, lefthand side of the pump station.

The expansion tank should be connected to the pump station using the Onix pipe provided. The use of

Teflon tape on the threaded fittings is recommended.

Step 1. Cut the Onix tubing to desired length with a sharp blade.

Step 2. Thread the female adapter to the expansion tank.

Step 3. Slip ring clamp onto the Onix tubing. Press barbed end of adapter into the Onix tubing (a little

water on the barbs will help). Place ring clamp over center of barbs and release.

Step 4. Thread the male adapter into the pump station. Tighten the expansion tank fitting with two

wrenches taking special care not to stress the expansion tank support pipe.

Step 5. Slip ring clamp onto the Onix tubing. Press barbed end of adapter into the Onix tubing (a little

water on the barbs will help). Place ring clamp over center of barbs and tighten.

󱚡 NOTICE

Only make ﬁnal expansion tank connection (Step 5) after system pressure test is complete

and test pressure is released from the system.

Expansion vessel may only be installed with pipe connection on top. Horizontal or inverted

orientations are not acceptable.

7.9. Fill and Pressurize

a) Heat Transfer Fluid: The Apricus pump station is designed for closed loop configuration using a freeze

resistance heat transfer fluid. Refer to Section 3.31 and Appendices 11-18 for information.

Before commencing installation make a rough calculation of the volume of heat transfer fluid that will be

required, and what size buckets will be needed during the fill process.

Example: Installation of 50 foot of ¾” pipe and one AP-30 = 1.44 Gallons

In addition, you will need to consider the volume of the coil heat exchanger, if present. The coil volume is

normally provided by the tank manufacturer on the tank specification sheet.

b) Charging Equipment: Apricus recommends using a professional charging station in order to streamline

the process considerably.
