General Installation Information
Safety Considerations
WARNING: Before performing service or maintenance operations on a system, turn
off main power switches to the indoor unit. If applicable, turn off the
accessory heater power switch. Electrical shock could cause personal injury.
Installing and servicing heating and air conditioning equipment can be
hazardous due to system pressure and electrical components. Only trained and
qualified service personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform the basic maintenance
functions of cleaning coils and cleaning and replacing filters. All other
operations should be performed by trained service personnel. When working on
heating and air conditioning equipment, observe precautions in the literature,
tags and labels attached to the unit and other safety precautions that may
apply.
Follow all safety codes. Wear safety glasses and work gloves. Use a quenching
cloth for brazing operations and have a fire extinguisher available.
Unit Location Locate the unit in an indoor area that allows for easy removal
of the filter and access panels. Location should have enough space for service
personnel to perform maintenance or repair. Provide sufficient room to make
water, electrical and duct connection(s). If the unit is located in a confined
space, such as a closet, provisions must be made for return air to freely
enter the space by means of a louvered door, etc. Any access panel screws that
would be difficult to remove after the unit is installed should be removed
prior to setting the unit. On horizontal units, allow adequate room below the
unit for a condensate drain trap and do not locate the unit above supply
piping. Care should be taken when units are located in unconditioned spaces to
prevent damage from frozen water lines and excessive heat that could damage
electrical components.
WARNING: To avoid equipment damage and possible voiding of warranty, be sure
that properly sized strainers are installed upstream of both brazed plate heat
exchangers to protect them against particles in the fluid.
Moving and Storage
Move units in the normal “up” orientation. Horizontal units may be moved and
stored per the information on the packaging. Do not stack more than three
units in total height. When the equipment is received, all items should be
carefully checked against the bill of lading to be sure all crates and cartons
have been received. Examine units for shipping damage, removing the units from
the packaging if necessary. Units in question should also be internally
inspected. If any damage is noted, the carrier should make the proper notation
on the delivery receipt, acknowledging the damage.
Installing Vertical Units
Prior to setting the unit in place, remove and discard the compressor hold
down shipping bolt located at the front of the compressor mounting bracket.
Vertical units are available in left or right air return configurations. Top
flow vertical units should be mounted level on a vibration absorbing pad
slightly larger than the base to provide isolation between the unit and the
floor. It is not necessary to anchor the unit to the floor (see figure below).

Installation Notes
Typical Unit Installation
Unit Location
Locate the unit in an indoor area that allows for easy removal of the filter
and access panels. Location should have enough space for service personnel to
perform maintenance or repair. Provide sufficient room to make water,
electrical and duct connection(s). If the unit is located in a confined space,
such as a closet, provisions must be made for return air to freely enter the
space by means of a louvered door, etc. Any access panel screws that would be
difficult to remove after the unit is installed should be removed prior to
setting the unit. On horizontal units, allow adequate room below the unit for
a condensate drain trap and do not locate the unit above supply piping. Care
should be taken when units are located in unconditioned spaces to prevent
damage from frozen water lines and excessive heat that could damage electrical
components.
Water Piping
Piping is usually design as `reverse return’ to equalize flow paths through
each unit. A short flexible pressure rated hose is used to make connection to
the fixed building
piping system. This hose is typically stainless steel braid and includes a
swivel fitting on one end for easy removal and is flexible to help isolate the
unit for quieter operation. Isolation valves for servicing, y-strainers for
filtering and memory-stop flow valve or a balancing valve can be provided for
consistent water flow through the unit.
All unit source water connections are fittings that accept a male pipe thread
(MPT). Insert the connectors by hand, then tighten the fitting with a wrench
to provide a leakproof joint. The open and closed loop piping system should
include pressure/temperature ports for serviceability. The proper water flow
must be provided to each unit whenever the unit operates. To assure proper
flow, use pressure/ temperature ports to determine the flow rate. These ports
should be located at the supply and return water connections on the unit. The
proper flow rate cannot be accurately set without measuring the water pressure
drop through the refrigerant-to-water heat exchanger. Never use flexible hoses
smaller than the inside diameter of the water connection at the unit. Limit
hose length to 10 feet per connection. Check carefully for water leaks.

Installing Horizontal Units Remove and discard the compressor hold down
shipping bolt located at the front of the compressor mounting bracket prior to
setting the unit in place. Horizontal units are available with side or end
discharge.
NOTE: Left (Right) Return Side Discharge can be converted to Left (Right)
Return End Discharge or vice versa, without additional custom sheet metal
parts. Horizontal units are normally suspended from a ceiling by six 1/2 in.
diameter threaded rods. The rods are usually attached to the unit by hanger
bracket kits furnished with each unit.
Lay out and install the threaded rods and 1 5/8″ strut
channel as shown in the Horizontal Dimensional Data. The unit should be
pitched approximately 1/4 in. toward the drain in both directions to
facilitate the removal of condensate.
Some applications require the installation of horizontal units on an attic
floor. In this case, the unit should be set in a full size secondary drain pan
on top of a vibration absorbing pad. The secondary drain pan prevents possible
condensate overflow or water leakage damage to the ceiling. The secondary
drain pan is usually placed on a plywood base isolated from the ceiling joists
by additional layers of vibration absorbing material.
CAUTION: Do not use rods smaller than 1/2 in. diameter since they may not be
strong enough to support the unit. The rods must be securely anchored to the
ceiling.

Acoustical Considerations and Equipment Sound Performance
Sound Performance The unit is third party sound rated in accordance with ARI
260. Please consult the manufacture’sr Sound Performance Data Catalog for
details on the AHRI standard and sound performance data.
Recommendations for Noise Reduction Horizontal Unit Location · Specify
equipment with quietest sound power ratings · Do not locate units above areas
with a required NC 40
or less · Space WSHP at least 10 ft (3m) apart to avoid noise
summing of multiple units in a space. · Maximize the height of the unit above
the
ceiling (horizontal). · Suspend unit with isolation grommets that are
appropriately rated to reduce vibrations (horizontal).
Vertical Unit Location · Specify equipment with quietest sound power ratings ·
Space WSHP at least 10 ft (3m) apart to avoid noise
summing of multiple units in a space. · Acoustic ceiling coatings can greatly
reduce noise levels
in mechanical rooms. · Mount unit on a sound absorbing pad, extruded
polystyrene, rubber or cork pad.
Ductwork · Ensure return air grilles will not allow line of site noise to
transfer to adjacent space. Use a sound barrier or some other material to
isolate the grille from the unit. A supply grille, boot and short piece of
flex duct pointed away from the unit can greatly attenuate equipment noise. ·
Use a canvas isolation duct connector at the supply and return duct connection
of the unit. · Internally line the discharge and return duct within the first
4-8 feet of unit with acoustic insulation. Install an internally lined L’ shaped return duct elbow at return grille. Face the elbow away from adjacent units. · Always install at least one 90° elbow in the discharge duct to eliminate line of sight noise transmission of the blower. · Use turning vanes at all elbows and tees to reduce turbulence. · Limit supply duct velocities to less than 1,000 fpm · Design and install ductwork as stiff as possible · Allow 3 duct diameters both up and down stream of the unit before any fittings or transitions are installed. · Use duct sealant on all duct joints. · Install a short (2-4′) of flex duct on all branch ducts just prior to discharge boot or diffuser to reduce vibration and duct sound prior to delivery in the room. · Locate the branch duct balancing damper as far away from the diffuser as possible. · In ceiling plenum systems, install an internally linedL’ shaped
return duct elbow at unit. Face the elbow away from adjacent units
(horizontal).

Duct System
An air outlet collar is provided on vertical top flow units and all horizontal
units to facilitate a duct connection. A flexible connector is recommended for
discharge and return air duct connections on metal duct systems. Uninsulated
duct should be insulated with a minimum of 1-inch duct insulation. Application
of the unit to uninsulated ductwork in an unconditioned space is not
recommended as the unit’s performance will be adversely affected.
If the unit is connected to existing ductwork, check the duct system to ensure
that it has the capacity to accommodate the air required for the unit
application. If the duct is too small, as in the replacement of heating only
systems, larger ductwork should be installed. All existing ductwork should be
checked for leaks and repaired if necessary.
The duct system should be sized to handle the design airflow quietly and efficiently. To maximize sound attenuation of the unit blower, the supply and return plenums should include an internal duct liner of fiberglass or constructed of ductboard for the first few feet. On systems employing a sheet metal duct system, canvas connectors should be used between the unit and the ductwork. If air noise or excessive airflow is a problem, the blower speed can be changed.
Water Piping
The proper water flow must be provided to each unit whenever the unit
operates. To assure proper flow, use pressure/temperature ports to determine
the flow rate. These ports should be located at the supply and return water
connections on the unit. The proper flow rate cannot be accurately set without
measuring the water pressure drop through the refrigerant-to-water heat
exchanger.
All source water connections on commercial units are fittings that accept a male pipe thread (MPT). Insert the connectors by hand, then tighten the fitting with a wrench to provide a leakproof joint. When connecting to an open loop (groundwater) system, thread any copper MPT fitting into the connector and tighten in the same manner as described above.

VERSATEC 500 7-30 TON INSTALLATION MANUAL – Formerly Versatec XL
Condensate Drain
On vertical units, the internal condensate drain assembly consists of a drain
tube which is connected to the drain pan, a 3/4 in. PVC female adapter and a
flexible connecting hose. The female adapter may exit either the front or the
side of the cabinet. The adapter should be glued to the field-installed PVC
condensate piping. On vertical units, a condensate hose is inside all cabinets
as a trapping loop; therefore, an external trap is not necessary.
On horizontal and bottom flow units, a PVC stub or stainless steel tube is provided for condensate drain piping connection. An external trap is required (see below). If a vent is necessary, an open stand pipe may be applied to a tee in the field-installed condensate piping.

Water Quality
In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified service mechanic, as special solutions and pumping equipment are required. Hot water generator coils can likewise become scaled and possibly plugged. In areas
with extremely hard water, the owner should be informed that the heat
exchanger may require occasional flushing. Failure to adhere to the guidelines
in the water quality table could result in loss of warranty.
Units with cupronickel heat exchangers are recommended for open loop
applications due to the increased resistance to build-up and corrosion, along
with reduced wear caused by acid cleaning.

System Cleaning and Flushing
Cleaning and Flushing
Prior to start up of any heat pump, the water circulating system must be
cleaned and flushed of all dirt and debris.
If the system is equipped with water shutoff valves, the supply and return
runouts must be connected together at each unit location (This will prevent
the introduction of dirt into the unit, see Flushing with Water Shutoff Valve
Equipped Systems illustration). The system should be filled at the water make-
up connection with all air vents open. After filling, vents should be closed.

Supply Runout
Rubber Hose
Mains
Runouts Initially Connected Together
The contractor should start the main circulator with the pressure reducing
valve makeup open. Vents should be checked in sequence to bleed off any
trapped air and to verify circulation through all components of the system.
As water circulates through the system, the contractor should check and repair
any leaks found in the piping system. Drain(s) at the lowest point(s) in the
system should be opened for initial flush and blowdown, making sure water fill
valves are set at the same rate. Check the pressure gauge at the pump suction
and manually adjust the makeup water valve to hold the same positive pressure
both before and after opening the drain valves. Flushing should continue for
at least two hours, or longer if required, until drain water is clean and
clear.
The supplemental heater and/or circulator pump, if used, should be shut off.
All drains and vents should be opened to completely drain the system. Short-
circuited supply and return runouts should now be connected to the unit supply
and return connections.
Refill the system with clean water. Test the system water for acidity and
treat as required to leave the water slightly alkaline (pH 7.5 to 8.5). The
specified percentage of antifreeze may also be added at this time. Use
commercial grade antifreeze designed for HVAC systems only. EnvironolTM brand
antifreeze is recommended.
Once the system has been filled with clean water and antifreeze (if used),
precautions should be taken to protect the system from dirty water conditions.
Dirty water will result in system-wide degradation of performance, and solids
may clog valves, strainers, flow regulators, etc. Additionally, the heat
exchanger may become clogged which reduces compressor service life and can
cause premature unit failure.
In boiler/tower application, set the loop control panel set points to desired
temperatures. Supply power to all motors and start the circulating pumps.
After full flow has been established through all components including the heat
rejector (regardless of season), air vented and loop temperatures stabilized,
each of the units will be ready for check, test and start up and for air and
water balancing.
Ground Source Loop System Checkout
Once piping is completed between the unit pumping system and ground loop,
final purging and charging of the loop is needed. A high pressure pump is
needed to achieve adequate flow velocity in the loop to purge air and dirt
particles from the loop itself. Antifreeze solution is used in most areas to
prevent freezing. Flush the system adequately to remove as much air as
possible; then pressurize the loop to a static pressure of 40-50 PSI (summer)
or 50-75 PSI (winter). This is normally adequate for good system operation.
Loop static pressure may decrease soon after initial installation, due to pipe
expansion and loop temperature change. Running the unit for at least 30
minutes after the system has been completely purged of air will allow for the
“break-in” period. It may be necessary to adjust static loop pressure (by
adding water) after the unit has run for the first time. Loop static pressure
will also fluctuate with the seasons. Pressures will be higher in the winter
months than during the cooling season. This fluctuation is normal and should
be considered when charging the system initially.
Ensure the pump provides adequate flow through the unit by checking pressure
drop across the heat exchanger. Usually 2.25-3.0 gpm of flow per ton of
cooling capacity is recommended in earth loop applications.
20
VERSATEC 500 7-30 TON INSTALLATION MANUAL – Formerly Versatec XL
Open Loop Ground Water Systems
Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in unit capacity data tables in the specification catalog. 1.5-2 gpm of flow per ton of cooling capacity is recommended in open loop applications. Due to only minor differences in flow rate from low to high, only one solenoid valve should be used. The valve should be sized for full flow.
Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local codes, i.e. recharge well, storm sewer, drain field, adjacent stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal. Consult your local building and zoning departments to assure compliance in your area.

Setting Blower Speed – Variable Speed ECM
The ABC board’s Yellow Config LED will flash the current ECM blower speed
selections for G, low, and high continuously with a short pause in between.
The speeds can also be confirmed with the AID Tool under the Setup/ ECM Setup
screen. The Aux will not be flashed but can be viewed in the AID Tool. The ECM
blower motor speeds can be field adjusted with or without using an AID Tool.
Variable speed ECM Setup without an AID Tool
The blower speeds for G only, Low (Y1), and High (Y2/ Aux) can be adjusted
directly at the Aurora ABC board which utilizes the push button (SW1) on the
ABC board. This procedure is outlined in the ECM Configuration Mode portion of
the Aurora `Base’ Control System section. The Aux cannot be set manually
without an AID Tool.
Variable speed ECM Setup with an AID Tool
A much easier method utilizes the AID Tool to change
the airflow using the procedure below. First navigate to
the Setup screen and then select ECM Setup. This screen
displays the current ECM settings. It allows the technician

ZS Sensor Information
Zone Sensors can be wired in daisy chain as show or in a star or hybrid configuration. Maximum of 5 sensors per UPC. Maximum allowable load 210mA. See the UPC install manual for possible sensor combinations.
DIP Switch Value
1 2 4 8
ON 1 2 34
Each ZS sensor must have a unique address, but the addresses do not need to be sequential. Use the DIP switches on the back of the ZS sensor to set an address from 0 to 4. (0 is the factory default.) Each DIP switch has the value shown in the figure to the left. Turn on as many DIP switches as you need so that their total value equals the address.

Aurora Controls
Aurora Controls
The Aurora Control System is a complete commercial comfort system that can
bring all aspects of the HVAC system into one cohesive module network. The
Aurora System is available in two configurations: Aurora Base Control and
Aurora Advanced and Aurora Premium Control both with optional Aurora UPC for
DDC applications.

General Description
Application
The ABC microprocessor provides all the features necessary to operate today’s standard WSHPs that utilize dual capacity compressors and variable speed ECM/5 speed ECM blower motors with hot gas reheat. This control can communicate to a handheld diagnostic tool to help the installing contractor or service technician with equipment setup and service. By utilizing Modbus RTU communication protocol, the ABC board can communicate with additional devices on the Aurora network
Used for residential and commercial applications that use single or dual capacity compressors with PSC, 5-speed ECM, or variable speed ECM blower motors. This base control can also communicate to the AID Tool to display faults, inputs/outputs, and software revision. Commercial features such as hot gas reheat, slow opening water valve, and random start are also capable with the ABC board.
Display/Interface
Optional AID toll can be used for field service.
Protocol Standalone
Aurora Advanced Control adds the Aurora AXB expansion board and provides added I/O and standard features such as refrigerant, performance or energy monitoring.
· Refrigeration Monitoring provides Suction and discharge pressure, Suction,
liquid line temps and superheat and subcooling.
· Performance Monitoring provides entering and leaving loop water
temperatures, loop flow rate as well as heat of extraction or rejection rate
into the loop.
· Energy Monitoring provides realtime power measurement (Watt) of
compressor, fan, auxiliary heat and zone pump.
· Plus many more I/O options
Optional AID tool can be used for field service.
The Aurora Unitary Protocol Converter (UPC) is an integrated solution and communicates directly with the Aurora Heat Pump Controls and allows access/control of a variety of internal Aurora heat pump operations such as sensors, relay operation, faults and other information. In turn, the UPC then converts internal Aurora Modbus protocol to BACnet MS/TP, or N2 protocols and communicates to the BAS system. This provides the great benefit of complete control integration and a myriad of information available to the BAS from the heat pump control. Plus it also allows individual unit configuration such as ECM fan speeds or freeze protection setting directly over the BAS without the need for access to the actual heat pump.
The Aurora UPC is implemented with the Aurora heat pump control into our latest water source heat pumps. All Internal Aurora points are accessible to the UPC via firmware providing an integrated solution. All zone temperatures and zone sensors are connected to the UPC on an RNet bus, simplifying hook up at the unit. RNet sensors can include a combination of zone temperature and humidity, CO2, and VOC sensors. The UPC includes built-in support
