11. After tightening the hanger nut onto the exposed connector, disconnect and remove the rod.
12.
If applicable; use silicon tape to thoroughly wrap and seal the hanger connector sealing bolt (fig.
4.5). For hanger connector sealing bolts equiped with an o-ring or gasket, silicone tape is not
needed.
13. If applicable; insert the sealing bolt into the open connector, ensure it is properly seated and tighten it.
Do NOT over-tighten (fig. 4.6).
14. Fill 2 bar (30 psi) of precharge air or nitrogen and using a soap solution check for leaks all around
the air valve, pressure gauge, top nut and bottom flange.
15. Lift tank upright and attach to pressure system as described earlier in this manual.
16. Open gate valve and allow some water into tank and then pump more air/nitrogen to set tank to
appropriate precharge as described in section 1.3.
17. Now open isolation gate valve to allow full functionality of tank.
Note: For tanks with a flange instead of a hanger on top of the tank, first mount the membrane to
the top flange.
5. Disposal
Check with local authorities for proper disposal and recycling. Do not dispose of the manual - keep
it for further reference.
6. Warranty
Global Water Solutions Ltd. (GWS) warrants its SuperFlow™ tanks
for a period of 1 years from the date of manufacture for manufacturing defects on the steel shell.
Warranty applies to GWS products only when used for their intended purpose, and does not
apply if a defect is due to improper use of the product, result of accident, misuse, or abuse. If the
product was improperly installed or altered in any way, not specifically authorized by the factory,
the warranty is void. The warranty set forth in this paragraph is made expressly in lieu of all other
warranties expressed, or implied, including but not limited to merchantability or fitness for a
particular purpose.
For replacement of the membrane, provided the tank is installed by an authorized installer and
pre-charge is set properly as per instruction manual and the pre-charge is checked as per the same
manual at a time interval of every 3 months, warranty is granted for a period of 3 months from date
of manufacture on membrane defects.
In no event shall GWS be liable for cost of processing, lost profits, goodwill or any other
consequential or incidental damage of any kind resulting from the order or use of its products
whether arriving from breach of warranty, nonconformity to ordered specifications, delay in delivery,
or any loss sustained by the buyer nor will GWS be liable for labor and expenses necessary to
remove and reinstall replacement product.
To obtain service under this warranty, consumer must deliver alleged defective product, freight
prepaid, to an authorized GWS distributor or OEM partner. GWS will either issue credit or at its
option, repair or replace defective product freight prepaid to the distributor. GWS reserves the right
to make changes in construction, which, in its judgment, constitutes a product improvement.
All warranty is subject to verifiable proper installation, adjustment of pre-charge as per our
engineering bulletins and installation of a pressure relief valve as recommended in the installation
manual.
Standard manufacturer’s warranty as defined in the standard GWS warranty terms and conditions.
2.4 Solar Heating System
Connections
SuperFlow™ tanks can be used in the solar
liquid loop of indirect thermal transfer systems
and may be mounted either on the suction
or pressure side of the circulation pump.
If a condenser is employed to cool
evaporated solar liquid it must be in the
location between the solar liquid loop and
the expansion tank. A relief valve should
be employed and maximum operating
parameters must not be exceeded. If the
temperature of the solar system has the
potential to rise above the evaporation point
of the solar liquid, a condenser chamber or
coil is required between the solar collector
and the expansion tank (See Fig. 2.4).
2.5 Thermal Expansion Operating Principles
As water is heated it expands. A thermal expansion tank is used to accommodate for this natural
water expansion, which otherwise may lead to increased system pressure and cause damage to piping,
fittings and other system components. A thermal expansion tank uses a membrane sealed inside
the vessel to create a barrier between water and air chambers. The air chamber acts as a cushion
which compresses as heated water expands. The thermal expansion tank absorbs the expanded water
volume and ensures constant system pressure is maintained. Using a thermal expansion tank also
conserves water and energy. This is accomplished by eliminating the need to refill and reheat water
lost due to venting from the relief valve during heating cycles.
3. Maintenance
SuperFlow™ pressure tanks should be checked by an authorized service professional, every 3 months.
To check precharge, shut off power to the pump, isolate and drain the tank. Check precharge using a
pressure gauge. If needed, top up air to appropriate precharge level using an air pump or compressor.
Open isolation gate valve allowing the pump to fill the tank with water.
Always release all water and air from tank before disassembling the parts exposed to pressure such
as flanges, air valve, pressure gauge etc. Make sure that the system is switched off and no electricity
or electrical devices are running.
If the pump short cycles or the heating system relief valve constantly opens, check the air valve
mounted on the tank. If water bleeds from the valve the membrane has burst. Please call an authorized
service provider to replace the membrane with a factory replacement, following the instructions for
membrane replacement in this manual.
Check the quality of the water by draining water from the tank using the drain valve. If the water is
rusted, calcified, or has solid deposits, then either the membrane has failed which can be verified by
above mentioned process or the tank is blocked.
4. Membrane Replacement Instructions
1. Turn off the water and/or disconnect the power to the pump.
2. Release the air and drain all water from tank.
3.
Unbolt and remove the flange (water connection) from the tank.
4. Remove the nut and the washer on the top of the tank which is attached to the membrane hanger
that is anchoring the top of the membrane (fig. 4.1, fig. 4.4).
5.
Pull and remove the membrane through the bottom opening to which the flange was attached.
6. Remove the top connection membrane hanger from the damaged membrane, this can be reused
and should be cleaned.
7.
Take the membrane hanger and attach it to a rod, a cable or alike, as seen in fig. 4.2.
8. Pull the rod and hanger up through the membrane until the top of the hanger is protruding from
the top of the membrane (fig. 4.3).
9. Feed the rod from the bottom of the tank up through the opening at the top of the tank until the
hanger is protruding from the top of the tank and the threads are visible.
10. Slip the washer and then the hanger nut over the end of the rod/cable and tighten onto the
exposed connector (fig. 4.4).
