QUICK START-UP GUIDE | OPERATION
Accelera® 300 Quick Start-up Guide
A. OVERVIEW: This water heater hooks up like any other electric water heater, with a few minor
exceptions. Be sure to follow all state and local codes during installation. This page is not intended
to be a substitute for the installation manual. Be sure to follow all safety precautions.
B. UNPACKING: DO NOT unpack water heater unit 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. DO NOT lay the unit down
and DO NOT jar or tip the unit past 45 degrees on the hand truck. See: 10.6
C. INSTALLATION / WATER:
a. Location: Find a suitable location according to the manual. Install the condensate drain elbow at
this time. 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 recommended. See: 10.6
b. 3/4” Inlet from union provided. For hook-up, follow all state and local codes for check valves, expansion
tanks, shut off valves, gauges, etc. Install a 70 psi pressure reduction valve. Please note: water pressure
should not exceed 70 psi. See: 10.7
c. 3/4” Outlet from union to hot water line.
d. Install P&T Relief valve (supplied). Please note: 100 psi / 210 °F.
D. CONDENSATE DRAIN: Goes directly into a drain or use a condensate pump to drain into a suitable
location. See: 10.6.1
E. FILL & FLUSH TANK: Run water and be sure tank is full prior to turning on the electricity.
F. INSTALLATION / ELECTRICAL: Use a 240 Volt / 15 Amp double pole breaker and connect to water
heater L1, L2, and Ground. See: 16.2
CAUTION: RISK OF SCALDING. THERE IS A RISK OF SCALDING AT
OUTLET TEMPERATURES EXCEEDING 110 °F / 43 °C RISK OF SCALDING
WITHIN ABOUT 5 HOURS OF START-UP TIME, EXHAUST AIR
FLOW SHOULD BE APPROXIMATELY 6 °F LESS THAN THE INLET SIDE.

The water heater extracts heat from the ambient air and
utilizes this energy to heat water.
An 80 gallon water tank is part of the water heater. Foam
insulation is applied to the outside of the water tank to
prevent heat losses. The water heater casing is made
from powder-coated sheet steel.
The internally enameled water tank is supported by
three height-adjustable anti-vibration leveling feet.

SAFETY

3. Safety
This chapter provides an overview of all important
actions required for a safe and trouble-free operation.
3.1 General safety instructions
Operate the water heater only when fully installed and
with all safety equipment in place.
Unsuitable tools or incorrect handling can result in
damage to the water heater.
DANGER Scalding
The water is heated inside the water tank to
140 °F(60 °C). There is a risk of scalding at
outlet temperatures above 109 °F (43 °C).
»Ensure that outflowing water does not
directly contact your body.
CAUTION Injury
Where children or persons with limited
physical, sensory or mental capabilities are
allowed to control this water heater, ensure
that this will only happen under supervision
or after appropriate instruction by a person
responsible for their safety.
»Children should be supervised to ensure
that they never play with the water heater.
Never place any objects on top of the water heater.
Objects placed on top of the water heater
can increase the noise level developed by the
water heater through vibrations.
Never cover the water heater.
The water heater draws in air. Covering the
inlet slots reduces the air intake. This reduces
the efficiency of the water heater and can even
lead to one of the safety devices interrupting
the water heater operation.
3.2 Intended use
This water heater produces hot water automatically.
The water heater can be installed and operated in the
open as well as in enclosed spaces. The temperature of
the air that is drawn in during operation must not fall
below 43 °F(6 °C).
Any other use beyond that described shall be deemed
inappropriate. Observation of these instructions is also
part of the correct use of this water heater.
Any changes or modifications to this water heater void
all warranty rights.
3.3 Incorrect use
The following are not permitted:
- Do not heat anything other than potable water
- Do not use unqualified (unlicensed) personnel for
installation
- Do not use in an environment with greasy extract
air
This water heater must not be operated at ambient temperatures in excess of 107 °F
(42°C) or below 43°F (6 °C).
If outside air is directly drawn in ensure, that
the water heater is isolated from its power
supply when the air temperature falls below
43 °F(6 °C).
3.4 Personnel qualification
DANGER Injury
Incorrect handling can result in severe injuries
and material losses. Inadequately qualified
personnel cannot assess the potential risks.
Have the installation, initial start-up,
maintenance and repair steps carried out only
by the qualified individuals specified in the
respective chapters.
In the remainder of this manual, such qualified
individuals will be described as the "licensed installer."
3.5 Safety equipment
Wear safety shoes/boots during the transportation and
positioning of the water heater. Dry, this water heater
weighs 290 lb (130 kg.) Safety shoes/boots reduce the
risk of injury.
