Series 490W Wireless Hydronic Differential Pressure Manometer
Specifications - Installation and Operating Instructions
The Series 490W Wireless Hydronic Differential Pressure Manometer is the most
accurate and easy to operate manometer on the market. By using wireless transducers
and a mobile device, a single operator can monitor and balance a hydronic system in
less time than traditional hydronic balancers. The Series 490W transducers connect
wirelessly to a UHH6 or newer handheld device, or your own mobile device, to
monitor differential pressure and flow on up to three different valves. Being wireless,
there are no hoses to carry, snag on equipment or needing to be drained. The 490W
utilizes Dwyer's hydronic application software that contains valve charts for numerous
manufacturers, which converts differential pressure to flow directly on the screen.
Included with the 490W HKIT
1. Pressure transducers (2 per kit) with case
2. Installation and operating manual (IOM)
3. 1/4˝ SAE 45° x 1/4˝ female NPTF straight adapter (2 per kit)
4. 1/4˝ female NPT x 1/4˝ male NPT elbow fitting (2 per kit)
5. Piercing gauge adapters [2 per size] (6 per kit) -1/8˝ DIA x 1-1/2˝ length; 1/8˝ DIA x
3˝ length; 1/16˝ x 1-1/2˝ length
6. 1/4˝ female NPT x 1/4˝ quick connect coupler (2 per kit)
7. 4 pack AAA batteries
8. 490W hard carrying case
BATTERY INSTALLATION
The kit is shipped with 4 AAA batteries (2 for each sensor), which must be installed
before operation. Loosen the two screws on either side of the clear cap (they will stay
attached to the cap), and remove the cap from the transducer. Install the batteries
according to the housing markings and replace the top cap. Do not over tighten the
screws.
With the sensors set to sleep mode via the app (see DISCONNECTING FROM
SENSORS), the sensors can be stored in the case with the batteries still installed.
If the kit is going to be stored for a long time, however, it is recommended that the
batteries be removed to reduce the risk of leakage.
When battery replacement becomes necessary, use only a AAA alkaline (LR03) type
such as Energizer E92. These are recommended due to a decreased risk of battery
®
leakage, and the specified battery life is based on usage of them.
Use of an incorrect battery type could result in product damage or battery leakage.
Zinc-carbon types, often labeled heavy-duty, are not recommended because of the
increased potential for leakage.
