General Description
6
Purpose:
e-Series units are air-to-water Commercial Heat Pump Water Heaters
(CHPWHs) using R-513a refrigerant in a closed and factory charged circuit. A
double wall heat exchanger provides heat to a potable water circuit. Potable
water is piped to the heat pump in a loop to and from external storage tanks.
Circulation is provided by the integral circulator in the heat pump.
Usage:
the e-series of water heaters are designed to provide hot water in a “Single
Pass” configuration; meaning that water is delivered at full usable temperature
to the potable storage tank in one pass. This allows for faster recovery of usable
water temperatures than in traditional “Multi-Pass” configurations. This system
is not an “on demand” heater and does require external and stratified storage to
operate eectively. Building recirculation loops must be returned to a separate
“swing tank” to preserve this stratification.
Ease of Installation:
The enclosure is designed to minimize its footprint, and to simplify placement
considerations for multiple-unit installations. As a “monobloc” style heat pump,
the unit arrives ready to connect to electrical, condensate, optional ducting, and
potable water infrastructure in the field.
It features onboard defrost heaters and heat tracing for cold climate usage, an
integral circulator and control valve, and an internal condensate drain pan with
a pipe connection point. The system is coated to resist salt spray corrosion for
coastal environments. While typically installed outdoors, interior locations with
adequate and consistent ventilation or heat gain can also house the unit, such
as large server rooms or parking garages. e-Series heat pumps can also be
fully ducted, allowing installation indoors in rooms that would not otherwise be
suitable for the heat pump.

Controls and Electrical:
The e-Series line is available in 208-230 and in 440-480 3 phase variants. Units
require a main power feed and a secondary 120v power feed for the onboard
freeze protection, controls, and circulator. It is strongly recommended that the
120v power feed come from a power source with a backup generator if the unit
is installed in a location that experiences freezing conditions, allowing freeze
protection to continue during a power outage. Optionally, a Unified Power
Package accessory can be ordered and installed to bring all power in through a
single primary voltage power feed.
All e-Series units are MODBUS and BACNET capable, ready to be integrated
into BMS systems by 3rd party integrators using Bacnet/IP and MSTP protocols.
All units also ship with internet accessibility for observation, alarms, and
troubleshooting on Nyle’s Nimbus online portal.
All e-Series units have a CTA-2045 port for power utility demand management
and are certified UL 1995.

D1-Dimensional Information
Clearance Note 1:
Unit is designed to be installed with zero side clearance, and all typical service items are serviceable from the front.
However, defrost heaters would need to pull out to the side if replaced. Units may be installed with successive
units oset 6” to the rear to allow the evaporator mounted heaters to pull from the unit right side, or in the unlikely
event of element failure the unit could be temporarily disconnected and moved.
Clearance Note 2:
Bottom clearance to the ground varies by project requirements, and is driven by height required for any necessary
condensate drain pitch. Free discharge (unpiped) condensate applications are not generally recommended.
See “Water and Condensate Piping” section for more information about piped and free discharge condensate
applications.
Clearance Note 3:
If vibration transmission and/or seismic activity is a concern for your installation, account for the additional height
of vibration isolation or seismic measures as recommended by a qualified engineer.
Clearance Note 4:
Top clearance required for fan installation/removal. If fans are installed prior to mounting and unit can be moved to
replace fans in the event of failure, this can reduce to 1” clearance.

Before Ordering Your Heat Pump
14
Before Ordering Your Heat Pump
Nyle Water Heating Systems recommends following this pre-order checklist, to
minimize the chances of costly mistakes and potentially lengthy project delays:
Be sure to thoroughly review this manual and familiarize yourself with the equipment’s
installation requirements. The manual has been organized to follow the general
sequence of most installations. If any details are not clear or questions are not
answered contact your Nyle representative to resolve them ahead of time.
Review performance specifications against your intended installed environment and
water temperature requirements, and ensure the unit will perform appropriately for
your conditions.
Review physical specifications to ensure the unit will have adequate installation
space, support, clearances, drainage support, and airflow. Familiarize yourself
with piping, condensate, wiring, and ducting connections to ensure all attached
infrastructure will be able to access the unit. Remember additional installation height
may be needed for condensate drain pitch requirements.
Evaluate the need for backup heat production, especially in cold climates. e-Series
units turn o the compressor at 10 degree F outdoor temperature, and capacity is
lower in cold weather.
Freeze protection measures require separate 120v power to operate, or the
installation of an optional unified power package accessory. Ensure 120v power
feed to the unit has a backup generator for any installation where the unit will be
exposed to freezing temperatures during power outages.
Be clear on your plan to deliver, transport, mount, and secure the unit.
Double check the voltage requirements of the unit you intend to order, to make sure it
is compatible with the available voltage on site.
Air to Water heat pumps are multidisciplinary installations that may require any or
all of the following trade specialties to support: site prep/structural, electrical,
plumbing, ducting, automation/controls, refrigeration, and duct/piping insulation.
Be sure that various specialties involved in your project are well informed as to their
role in the installation and are properly certified and qualified in their specialties in
accordance with all governing codes and regulations.
Be sure that qualified refrigeration technicians are available for installation
troubleshooting support and ongoing system maintenance. If this is in question,
contact your local Nyle representative to discuss support options.

HeatWater.com | [e-mail] | [phone] | Rev. IM-E360-060523
Cold Climate Installation Considerations
15
Cold Climate Installation Considerations
e-Series heat pumps are intended to operate in cold climates. However, freeze
protection is an important part of the installation and design planning for these
installations. One option is to install the unit in freeze protected spaces and duct
them to the outside. See the Optional Ducting section of this manual for details.
For exterior installations, additional measures are required.
IMPORTANT: Cold climate outdoor installations require close
attention to the following considerations. Failure to follow these
guidelines can result in equipment failure and/or severe water
damage to the property.
The heat pump has two steps of internal freeze protection for outdoor
applications:
1. First are the onboard, active heating measures: all internal water side
components are insulated and heat traced, which activate only when water
temperatures in the unit get too close to freezing. The condensate pan
has water sensing and pan heating, which activates when water is present
in the pan during freezing conditions.
2. In the event that active heating fails to keep water temperatures above
freezing, the heat pump will run its circulator to draw heat from the
attached storage tank as an emergency measure. It is imperative that
attached piping does not prevent this fluid exchange with the storage
tanks. Attached valves and components must allow free flow between
the heat pump and storage tank at all times: solenoid valves and other
automatic shutos are not recommended.
Considerations for Exterior Applications in cold climates:
1. All water and condensate piping that is exposed to freezing temperatures
must be insulated and heat traced as per local code and/or heat tracing
manufacturer’s requirements. It is recommended that this tracing be
thermostatically activated to run as needed, not always on. Self regulating
cable is recommended.

Cold Climate Installation Considerations
16
2. e-Series units have a 120v power feed in addition to their primary 3
phase power feed. The 120v feed is intended to be connected to a power
source with a generator or battery backup. See Table 2 for electrical
specifications. Backup electrical support is important to protect the unit
in case of power failure on the main circuit, unless the main circuit is itself
backed up by a generator. For installations that do not require backup
power, the unified power package accessory can condense incoming
power to a single point electrical feed.
3. Water pipes in exterior space should pitch down toward the e-Series pipe
entry points, so if a manual drain down is necessary, all exterior piping can
drain to the dump valve within the heat pump.
4. Condensate pipes must pitch down to a freeze protected drain point or
to conditioned space for vents or condensate pumps for further handling.
Do not install vents or condensate pumps outside.
5. If filling the system in cold weather, ensure the 120v power circuit is active
BEFORE filling the circuit. See Pre-Startup and Startup procedures in this
manual for more information.
