2.2 Electrical Requirements
See appliance rating decal for electrical service requirements. The appliance must be electrically
supplied and grounded in accordance with the requirements of the authority having jurisdiction or,
in the absence of such requirements, with the latest edition of the National Electrical Code
ANSI/NFPA No. 70. In Canada, the electrical service must conform to local electrical codes
and/or CSA C22.1, Canadian Electrical Code, Part 1.
•All wiring between the unit and field installed devices must be made with type T copper wire.
•Line voltage wires must be enclosed in approved conduit or metal-clad cable.
•To avoid serious damage, DO NOT energize the unit until the appliance is full of water.
2.3 Handling and Locating the Element
W A R N I N G :
Use industry-standard safe rigging methods, such as spreader bars, when attempting to lift or
move this product. Failure to follow industry standard safe rigging methods can result in property
damage, serious injury or death.
The Element unit must be installed indoors so it is not exposed to freezing temperatures. The
water heater may be installed directly on a combustible floor.
Install the unit on a level surface near a floor drain. Position the unit so if the tank or water
connections should leak, water damage will not occur to the adjacent area or to lower floors of
the building. The manufacturer’s warranty does not cover water damage.
Protect all electrical components and connections from water (dripping, spraying, rain, etc.)
during operation and service.
Position the unit where the vent and air intake piping, when installed, will remain within the
maximum equivalent lengths allowed. See Section 7: Venting.
Allow for minimum service clearances as described in Figure 8Error! Reference source not
found..
2.4 Theory of Operation
Element Q heats, treats, mixes, and reports on operation to the user. Following Figure 2 from the
cold inlet, incoming potable water is filtered through Filter 1, a 5µm sediment filter. Next it passes
through the AquaSolve Template Actuated Crystallization (TAC) anti-scale unit. Following that it
passes through the cold water Lync UV system to inactivate pathogens. Not shown in the figure is
the booster pump. The intent of the booster pump is not to compensate for lower incoming cold
water pressure but rather to overcome any internal losses with the unit.
Following the booster pump and tee connection, cold water enters the Lync Q water heater. It
exits from the top where there is another tee to supply the hot water to the building, and the
DigiTemp Jr digital mixing valve that supplies mixed water for distribution to end user fittings and
fixtures, e.g. showers and faucets.
On return, the recirculated water is passed through an additional 5µm sediment filter and an
additional recirc water Lync UV system for ongoing pathogen prevention. The recirc water enters
the Lync Q water heater at a mid-tank port.
A recirculation sanitation pump and check valve are located between the water heater exit and
entrance for tank volume sanitation cycles.

Internal and external communications are covered by a separate Element Communications
Manual for System Integrators. Refer to that for connections to building automation systems
(BAS) or building management systems (BMS).
The Edge SC Controller contains a highly sensitive capacitive touchscreen. It continuously checks
for user interaction at a high frequency. Boiler room environments are often harsh,
electromagnetically noisy and dirty, and can experience wide temperature ranges, all of which can
damage sensitive electronic components.
Lync has taken precautions to ensure proper operation of your unit. The Edge SC Controller is
built with a high-quality glass screen for clarity and performance and has an optically bonded
overlay covering the front of the enclosure to prevent dirt and liquids from affecting its operation.
Installation consists of the following tasks, in summary:
1. Unpack the Element unit from its shipping container (Section 3.3).
2. Position, secure, and level the unit at the site. Ensure the base is level (Section 3.4).
3. Verify condensate discharge piping is installed per local codes (Section 5)
4. Connect and install gas supply (Section 6) and venting (Section 7)
5. Connect the domestic hot water (DHW) supply piping and mixed (i.e. tempered) supply
from the unit.
6. Connect DHW return and cold-water supply (CWS) piping.
7. Flow water through the unit to remove any entrapped air.
8. Connect external AC power to the rear of the Element enclosure.
9. Commission the water heater (Section 8).
10. Connect Element to the internet via network connection.
11. Set up the EdgeSC Controller (Section 9)
12. Configure Element per system and site needs.
3.2 Receiving and Inspecting the Unit
Inspect the unit completely upon receipt from the freight carrier before signing the bill of lading.
Inspect the appliance and all accompanying parts for signs of impact or mishandling. Verify the
total number of pieces shown on packing slips with those actually received. Contact the freight
carrier immediately if any damage or shortage is detected.
Check the data decal on the appliance. Be sure the electrical, water and gas supply is adequate
for the installation.
Carefully remove all side and top shipping supports and bracing. If possible, do not remove the
wooden base/skid assembly until the product has been moved to its final location for installation
and operation (see: 2.3 Handling and Locating the Element).
3.3 Unpacking and Moving the Unit
Each Element unit is shipped as a single crated unit. The packaged shipping weight is
approximately 3,000 lbs (1,360 kg).

Element
Section 3: Installation
L-OMM-0003_A •10/8/2021 Technical Support •[phone] •Mon-Fri, 8 am - 5 pm EST Page 18 of 157
The unit must be moved with the proper equipment (forklift, pallet jack, etc.) to avoid possible
injury to personnel or damage to the shipping container or unit. The shipping carton should be
inspected for any damage incurred during transit prior to signing the bill of lading.
NOTE: Each unit has a Tip-N-Tell indicator on the outside of the shipping container, which
indicates if the unit has been turned on its side during shipment. If the Tip-N-Tell indicator is
tripped, do not sign for the shipment. Note the information on the carrier’s paperwork and request
a freight claim and inspection by a claims adjuster before proceeding. Notify delivering carrier
immediately of any damage to the packaging. Lync is not responsible for lost or damaged freight
1. Unpack the Element from its shipping container taking care not to damage the unit when
cutting away the packaging material.
2. Each unit includes an installation kit. Verify that each of the following has been received:

3. If optional accessories were ordered, they may be packed within the unit’s shipping
container, factory installed on the unit, or packed and shipped in a separate container. Any
standard or optional accessories shipped separately should be identified and stored in a safe
place until ready for installation or use.
3.3.1Moving the Element
Inspect the path and all thresholds that unit will move through to ensure appropriate clearance. It
is recommended to use the installed pallet to move the Element to the installation site, if possible.
The pallet is fastened to the unit with (6) hex-head lag bolts, as shown in Figure 4.
Figure 4 –Locations of Lag Bolts to Remove Unit from Wood Pallet.

Moving the Unit with a Crane: Remove the rear, top cover panel to expose the rear eyebolts.
Open the front door to fasten the front rigging hooks. Spreader bars are recommended when
lifting with a crane, to prevent damage to the unit.
Figure 5 –Lifting Points
Moving the Unit with Pallet Forks: Ensure that the middle of Element is supported when using
forks from the front, and that the middle of the water heater is supported when using forks from
the rear. When complete, install the front fascia plate.

Figure 7 –Crossbar Insertion Points
3.4 Site Selection and Preparation
No concrete pad is required for installation of the Element. Ensure that the site selected includes
the following:
•Access to AC Input Power: 120 VAC, Single-Phase, 60 Hz @ 30 Amps
W A R N I N G :
Always follow local codes and regulations to reduce risk of electrical shock.
•Access to a natural gas line or LP gas (propane) line.
oNatural gas units require a minimum flowing pressure of 3.5 inches of water
column (0.87 kPa) with the unit operating at maximum BTU output. Maximum static
pressure is 14.0 inches of water column (3.49 kPa).
oLP gas units require minimum flowing pressure of 8.0 inches of water column (2.0
kPa) with the unit operating at maximum BTU output. Maximum static pressure is
13.0 inches of water column (3.24 kPa).
•A cold-water connection protected by a backflow prevention assembly per local codes.
•Access to the internet via RJ45 connection. Ensure any firewalls, IP filters, and MAC filters
are appropriately configured.
•Floor drain, for condensate and water discharge. Maximum water discharge is from a fully
open 1” CTS pipe at system return pressure. Discharge to floor drain shall pass through
an air gap per local codes.
W A R N I N G :
Condensate discharge from the Element can be corrosive and damage the drain, waste, vent
(DWV) piping system. It is recommended to install a condensate neutralizer such as the Lync
CN-2 between the Element condensate drain tube and discharge to drain.
Risk of flooding if floor drain is not sized or located properly. Risk of excessive splashing from
a drain grate can create a slip and fall hazard.
