1. Uvod
The Eastman Thermal Expansion Tank is engineered to safeguard residential water heating systems from the detrimental effects of thermal expansion. As water heats, it expands, increasing pressure within a closed plumbing system. This tank absorbs the expanded water, preventing excessive pressure buildup that can damage water heaters, pipes, and fixtures, thereby extending the service life of your water heating system.

4. Nastavitev in namestitev
Proper installation is crucial for the effective operation of your thermal expansion tank. This tank is designed for indoor installation and connects via a 3/4 inch MIP connection.
Koraki pred namestitvijo:
- Verify System Pressure: Before installation, measure your household's static water pressure. The expansion tank comes factory pre-charged at 40 PSI. For optimal performance, the tank's air charge pressure should match your system's static water pressure. Adjust the tank's air pressure using a bicycle pump or air compressor via the Schrader valve located at the bottom of the tank.
- Izklopite dovod vode: Locate the main water shut-off valve to your home and turn it off.
- Drain Water Heater: Open a hot water faucet in your home to relieve pressure and drain some water from the water heater.
Postopek namestitve:
- Izberite lokacijo: Install the expansion tank on the cold water supply line to the water heater, typically between the main shut-off valve and the water heater inlet. It can be installed vertically or horizontally.
- Nanesite tesnilno maso za navoje: Apply appropriate thread sealant (e.g., PTFE tape or pipe dope) to the 3/4 inch MIP threads of the expansion tank.
- Priključitev rezervoarja: Thread the expansion tank onto the cold water inlet pipe of the water heater or a suitable tee fitting in the cold water supply line. Tighten securely with a wrench, but do not overtighten.
- Obnova oskrbe z vodo: Slowly open the main water shut-off valve to refill the system. Check for leaks at all connections.
- Odzračevanje zraka: Open hot water faucets in your home to purge any air from the plumbing system.

5. Navodila za uporabo
The Eastman Thermal Expansion Tank operates passively. Once correctly installed and pre-charged to match your system's static water pressure, it automatically accommodates the expansion of water as it heats. No manual operation is required during normal use.
The tank's butyl rubber diaphragm separates the air pre-charge from the system water. As water heats and expands, it pushes against the diaphragm, compressing the air in the tank. When hot water is drawn or the system cools, the compressed air pushes the water back into the system, maintaining stable pressure.
6. Vzdrževanje
Regular inspection of your thermal expansion tank can help ensure its continued effectiveness.
- Letni pregled tlaka: Annually, check the air charge pressure of the tank. Turn off the water supply to the tank, drain the water from the tank side (if possible), and use a pressure gauge on the Schrader valve to verify the pressure. Adjust if necessary to match your system's static water pressure.
- Preverite puščanje: Periodically check the tank and connections for any signs of water leaks or corrosion.
- Check for Waterlogging: Tap the top and bottom of the tank. If both sound solid, the tank may be waterlogged, indicating a failed diaphragm. A properly functioning tank will sound hollow on the air side and solid on the water side.
7. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Water heater relief valve frequently discharges | Excessive system pressure due to thermal expansion; tank is waterlogged or improperly charged. | Check tank air charge pressure and adjust to match system pressure. If waterlogged, replace the tank. |
| Tank feels heavy and sounds solid when tapped | Diaphragm failure, tank is waterlogged. | Replace the thermal expansion tank. |
| Puščanja na priključkih | Improperly tightened connection or insufficient thread sealant. | Turn off water, drain system, reapply thread sealant, and tighten connection. |
| Low water pressure fluctuations | Tank air charge too low or tank too small for system. | Adjust tank air charge. Consult a professional if tank size is suspected. |
