General information

ACCELERA® 220/300 E QUICK START-UP
GUIDE
Overview:
Installation of this water heater is similar to standard electric water heaters, with a few minor exceptions. Be sure to follow all state
and local codes during installation. This Quick Start-up Guide is not intended to be a substitute for the complete installation manual.
Be sure to follow all safety precautions.
Unpacking:
DO NOT unpack the water heater until it is located at the point of installation. Follow all instructions in the manual and be sure to use
caution, as this unit is top heavy. After unpacking, DO NOT lay the unit down and DO NOT jar or tip the unit past 45 degrees on a hand
truck. If the appliance has not been completely vertical during transport or setup, it must rest in a vertical position for at least one hour
before commissioning.
Installation of water connections:
1. Find a suitable location that fi ts the room spacing guidelines on the next page. The minimum volume of the room is 10´ x 10´ x 8´.
Be sure vents are parallel to the wall with the fan facing the most open area along that wall. Please note: a drain pan is recom-
mended, and may be code in some areas.
2. The inlet & outlet plumbing connections on the unit are 1˝ male NPT. It is recommended to use union connections for easier ser-
viceability. Install a boiler drain at the cold water inlet for easier draining of the tank. Do not use hemp for sealing.
3. The temperature & pressure (T&P) safety valve port is ¾˝ female NPT. A T&P valve is supplied which is rated to release water at
100 psi and/or 210 °F (99 °C). Plumb this connection to a bucket or directly to a drain. If it is plumbed to a bucket, check it often for
any accumulated water.
For hook-up, follow all state and local codes for check valves, expansion tanks, shut off valves, gauges, etc.
Note
A 70 psi (4.8 bar) pressure reducing valve must be in-
stalled to ensure the pressure of the incoming water line
never exceeds 70 psi (4.8 bar). (See 11.1, "Water connec-
tion", pg. 21) .
Condensate drain:
Run the condensate drain connection directly into a drain or use a condensate pump to drain into a suitable location (See 11.2, "Con-
densate drain", pg. 22).
Fill & flush tank:
Run water and be sure the tank is full prior to turning on the electricity.
Installation/electrical:
Use a 240 Volt / 15 Amp double pole breaker and connect to the water heater L1,L2 & ground (See 11.4, "Power supply", pg. 23).
Recirculation loop:
Stiebel Eltron advises against the installation of this appliance in any recirculation loop. If a recirculation loop is required, see 11.1.6,
"Recirculation loop", pg. 22 for recirculation installation requirements.
