2. At the rear of the Element, remove the panel screws on the left service panel per Figure 17
a) Check if terminals
R1
and
R2
are jumped. If they are, nothing more needs to be done. If
the terminals are not jumped but have wires connected to them, this indicates that a
remote on/off relay is controlling the water heater from the Building Automation System.
These wires must be removed and the terminals must be jumped prior to startup.
Remember to remove jumper and reconnect wires after startup is complete.
b) Re-check all components and ensure all wire connections are tight.
c) Close the service panel cover and secure panel screws.

8.5.2 Confirm Water Tanks are Completely Filled
IMPORTANT:
Using the T&P Relief valve alone to vent the tank will NOT allow the tank to completely fill!
1. Close the water heater drain valve.
2. Fully open shutoff valves on the cold-water inlet and hot water outlet piping to the unit.
3. Open the T&P valve to vent the tank. Close the valve when flow is observed.
4. Open a nearby hot water faucet(s) to allow trapped air to escape from the piping.
5. A steady flow observed from the hot water faucet(s) indicates the tank is full.
6. Close the hot water faucet(s).
8.5.2.1
Element as a Booster Water Heater (Optional)
If configuring the Element as a booster water heater, the fill water supplied by the general
purpose water heater should be a minimum of 140°F.
