Inspection
Upon receipt of the equipment, carefully check the shipment
against the bill of lading. Make sure all units have been received.
Inspect the packaging of each unit, and inspect each unit for
damage. Insure that the carrier makes proper notation of any
shortages or damage on all copies of the freight bill and completes
a common carrier inspection report. Concealed damage not
discovered during unloading must be reported to the carrier within
15 days of receipt of shipment. If not led within 15 days, the
freight company can deny the claim without recourse. Note: It is
the responsibility of the purchaser to le all necessary claims with
the carrier. Notify your equipment supplier of all damage within
fteen (15) days of shipment.
Storage
Equipment should be stored in its original packaging in a clean,
dry area. Store units in an upright position at all times. Stack
units a maximum of 3 units high.
Unit Protection
Cover units on the job site with either the original packaging or an
equivalent protective covering. Cap the open ends of pipes stored
on the job site. In areas where painting, plastering, and/or spraying
has not been completed, all due precautions must be taken to
avoid physical damage to the units and contamination by foreign
material. Physical damage and contamination may prevent proper
start-up and may result in costly equipment clean-up.
Examine all pipes, ttings, and valves before installing any of
the system components. Remove any dirt or debris found in or
on these components.
Pre-Installation
Installation, Operation, and Maintenance instructions are
provided with each unit. Horizontal equipment is designed for
installation above false ceiling or in a ceiling plenum. Other
unit congurations are typically installed in a mechanical room.
The installation site chosen should include adequate service
clearance around the unit. Before unit start-up, read all manuals
and become familiar with the unit and its operation. Thoroughly
check the system before operation.
IOM Instructions HBH/V CompaCt Heat Controller, Inc.
R-410A.

CAUTION! All three phase scroll compressors must have
direction of rotation veried at start-up. Verication is achieved by
checking compressor Amp draw. Amp draw will be substantially
lower compared to nameplate values. Additionally, reverse rotation
results in an elevated sound level compared to correct rotation.
Reverse rotation will result in compressor internal overload trip
within several minutes. Verify compressor type before proceeding.
CAUTION! DO NOT store or install units in corrosive
environments or in locations subject to temperature or
humidity extremes (e.g., attics, garages, rooftops, etc.).
Corrosive conditions and high temperature or humidity can
signicantly reduce performance, reliability, and service life.
Always move and store units in an upright position. Tilting
units on their sides may cause equipment damage.
NOTICE! Failure to remove shipping brackets from spring-
mounted compressors will cause excessive noise, and
could cause component failure due to added vibration.
CAUTION!
CAUTION!

CAUTION! CUT HAZARD - Failure to follow this caution
may result in personal injury. Sheet metal parts may have
sharp edges or burrs. Use care and wear appropriate
protective clothing, safety glasses and gloves when
handling parts and servicing heat pumps.
General Information
Prepare units for installation as follows:
1. Compare the electrical data on the unit nameplate with
ordering and shipping information to verify that the correct
unit has been shipped.
2. Keep the cabinet covered with the original packaging until
installation is complete and all plastering, painting, etc. is
nished.
3. Verify refrigerant tubing is free of kinks or dents and that it
does not touch other unit components.
4. Inspect all electrical connections. Connections must be
clean and tight at the terminals.
5. Remove any blower support packaging (water-to-air units
only).
6. Loosen compressor bolts on units equipped with
compressor spring vibration isolation until the compressor
rides freely on the springs. Remove shipping restraints.
7.
Some airow patterns are eld convertible (horizontal units
only). Locate the airow conversion section of this IOM.

Horizontal Installation
Mounting Horizontal Units
Horizontal units have hanger kits pre-installed from the factory
as shown in Figure 1. Figure 3 shows a typical horizontal unit
installation.
Horizontal heat pumps are typically suspended above a ceiling
or within a soft using eld supplied, threaded rods sized to
support the weight of the unit.
Use four (4) eld supplied threaded rods and factory provided
vibration isolators to suspend the unit. Hang the unit clear of the
oor slab above and support the unit by the mounting bracket
assemblies only. DO NOT attach the unit ush with the oor
slab above.
Pitch the unit toward the drain as shown in Figure 2 to improve
the condensate drainage. On small units (less than 2.5
tons/8.8kW) ensure that unit pitch does not cause condensate
leaks inside the cabinet.

Horizontal Unit Location
Units are not designed for outdoor installation. Locate
the unit in an INDOOR area that allows enough space
for service personnel to perform typical maintenance or
repairs without removing unit from the ceiling. Horizontal
units are typically installed above a false ceiling or in a
ceiling plenum. Never install units in areas subject to
freezing or where humidity levels could cause cabinet
condensation (such as unconditioned spaces subject
to 100% outside air). Consideration should be given to
access for easy removal of the lter and access panels.
Provide sufcient room to make water, electrical, and
duct connection(s).
If the unit is located in a conned 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 difcult to remove after the unit is
installed should be removed prior to setting the unit. Refer
to Figure 3 for an illustration of a typical installation. Refer
to unit engineering design guide for dimensional data.
In limited side access installations, pre-removal of the
control box side mounting screws will allow control box
removal for future servicing (HB units only).
Conform to the following guidelines when selecting
unit location:
1. Provide a hinged access door in concealed-spline
or plaster ceilings. Provide removable ceiling
tiles in T-bar or lay-in ceilings. Refer to horizontal
unit dimensions for specic series and model in
unit submittal data. Size the access opening to
accommodate the service technician during the
removal or replacement of the compressor and the
removal or installation of the unit itself.
2. Provide access to hanger brackets, water valves
and ttings. Provide screwdriver clearance to access
panels, discharge collars and all electrical connections.
3. DO NOT obstruct the space beneath the unit with
piping, electrical cables and other items that prohibit
future removal of components or the unit itself.
4. Use a manual portable jack/lift to lift and support the
weight of the unit during installation and servicing.
The installation of water source heat pump units and all
associated components, parts and accessories which
make up the installation shall be in accordance with
the regulations of ALL authorities having jurisdiction
and MUST conform to all applicable codes. It is the
responsibility of the installing contractor to determine and
comply with ALL applicable codes and regulations.

IOM Instructions HBH/V CompaCt Heat Controller, Inc.

Figure 3: Typical Horizontal Unit Installation
Air Coil
To obtain maximum performance, the air coil should be cleaned
before start-up. A 10% solution of dishwasher detergent and
water is recommended for both sides of the coil. A thorough
water rinse should follow. UV based anti-bacterial systems
may damage e-coated air coils.
NOTICE! Installation Note - Ducted Return: Many horizontal
WSHPs are installed in a return air ceiling plenum application
(above ceiling). Vertical WSHPs are commonly installed in a
mechanical room with free return (e.g. louvered door). Therefore,
lter rails are the industry standard and are included on Heat
Controller, Inc., commercial heat pumps for the purposes of
holding the lter only. For ducted return applications, the lter rail
must be removed and replaced with a duct ange or lter rack.
Canvas or exible connectors should also be used to minimize
vibration between the unit and ductwork.

Overview
Horizontal units can be eld converted between side (straight)
and back (end) discharge using the instructions below.
Note: It is not possible to eld convert return air between
left or right return models due to the necessity of
refrigeration copper piping changes.
Preparation
It is best to eld convert the unit on the ground before hanging.
If the unit is already hung it should be taken down for the eld
conversion.
Side to Back Discharge Conversion
1. Place unit in well lit area. Remove the screws as shown in
Figure 4 to free top panel and discharge panel.
2. Lift out the access panel and set aside. Lift and rotate
the discharge panel to the other position as shown, being
careful with the blower wiring.
3.
Check blower wire routing and connections for tension or
contact with sheet metal edges. Reroute if necessary.
4. Check refrigerant tubing for contact with
other components.
5. Reinstall top panel and screws noting that the location for
some screws will have changed.
6. Manually spin the fan wheel to insure that the wheel is not
rubbing or obstructed.
7. Replace access panels.
Back to Side Discharge Conversion
If the discharge is changed from back to side, use above
instruction noting that illustrations will be reversed.
Left vs. Right Return
It is not possible to eld convert return air between left or right
return models due to the necessity of refrigeration copper
piping changes. However, the conversion process of side to
back or back to side discharge for either right or left return
conguration is the same. In some cases, it may be possible
to rotate the entire unit 180 degrees if the return air connection
needs to be on the opposite side. Note that rotating the unit will
move the piping to the other end of the unit.

Figure 6: Horizontal Condensate Connection
CAUTION! Ensure condensate line is pitched toward drain
1/4” per foot [21mm per m] of run.
Condensate Piping – Horizontal Units
CAUTION!
Pitch the unit toward the drain as shown in Figure 2 to
improve the condensate drainage. On small units (less
than 2.5 tons/8.8 kW), insure that unit pitch does not
cause condensate leaks inside the cabinet.
Install condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection as
shown in Figure 6.
Each unit must be installed with its own individual trap
and connection to the condensate line (main) or riser.
Provide a means to ush or blow out the condensate line.
DO NOT install units with a common trap and/or vent.
Always vent the condensate line when dirt or air can
collect in the line or a long horizontal drain line is
required. Also vent when large units are working against
higher external static pressure than other units connected
to the same condensate main since this may cause
poor drainage for all units on the line. WHEN A VENT
IS INSTALLED IN THE DRAIN LINE, IT MUST BE
LOCATED AFTER THE TRAP IN THE DIRECTION OF
THE CONDENSATE FLOW.
Duct System Installation
Proper duct sizing and design is critical to the
performance of the unit. The duct system should be
designed to allow adequate and even airow through
the unit during operation. Air ow through the unit MUST
be at or above the minimum stated airow for the unit
to avoid equipment damage. Duct systems should
be designed for quiet operation. Refer to Figure 3 for
horizontal duct system details or gure 8 for vertical duct
system details. A exible connector is recommended
for both discharge and return air duct connections on
metal duct systems to eliminate the transfer of vibration
to the duct system. To maximize sound attenuation of
the unit blower, the supply and return plenums should
include internal berglass duct liner or be constructed
from ductboard for the rst few feet. Application of the
unit to uninsulated ductwork in an unconditioned space
is not recommended, as the unit’s performance will be
adversely affected.
At least one 90° elbow should be included in the supply
duct to reduce air noise. If air noise or excessive air ow
is a problem, the blower speed can be changed. For
airow charts, consult submittal data for the series and
model of the specic unit.
If the unit is connected to existing ductwork, a previous
check should have been made to insure that the
ductwork has the capacity to handle the airow required
for the unit. If ducting is too small, as in the replacement
of a heating only system, larger ductwork should be
installed. All existing ductwork should be checked for
leaks and repaired as necessary.

unit. Refer to Figures 7 and 8 for typical installation
illustrations. Refer to unit submittal data or engineering
design guide for dimensional data.
1. Install the unit on a piece of rubber, neoprene or
other mounting pad material for sound isolation. The
pad should be at least 3/8” [10mm] to 1/2” [13mm] in
thickness. Extend the pad beyond all four edges of
the unit.
2. Provide adequate clearance for lter replacement
and drain pan cleaning. Do not block lter access
with piping, conduit or other materials. Refer to
unit submittal data or engineering design guide for
dimensional data.
3. Provide access for fan and fan motor maintenance
and for servicing the compressor and coils without
removing the unit.
4. Provide an unobstructed path to the unit within the
closet or mechanical room. Space should be sufcient
to allow removal of the unit, if necessary.
5. In limited side access installations, pre-removal of the
control box side mounting screws will allow control box
removal for future servicing (TC units only).
6. Provide access to water valves and ttings and
screwdriver access to the unit side panels, discharge
collar and all electrical connections.

Vertical Installation
Sound Attenuation for Vertical Units
Sound attenuation is achieved by enclosing the unit within a
small mechanical room or a closet. Additional measures for
sound control include the following:
1. Mount the unit so that the return air inlet is 90° to the
return air grille. Refer to Figure 9. Install a sound bafe as
illustrated to reduce line-of sight sound transmitted through
return air grilles.
2.
Mount the unit on a rubber or neoprene isolation pad to mini-
mize vibration transmission to the building structure.
Figure 9: Vertical Sound Attenuation
Condensate Piping – Vertical Units
Vertical units utilize a condensate hose inside the cabinet as
a trapping loop; therefore an external trap is not necessary.
Figure 10a shows typical condensate connections. Figure 10b
illustrates the internal trap for a typical vertical heat pump.
Each unit must be installed with its own individual vent (where
necessary) and a means to ush or blow out the condensate
drain line. Do not install units with a common trap and/or vent.

Installation of Supply and Return Piping
Follow these piping guidelines.
1. Install a drain valve at the base of each supply and
return riser to facilitate system ushing.
2. Install shut-off / balancing valves and unions at each
unit to permit unit removal for servicing.
3. Place strainers at the inlet of each system
circulating pump.
4. Select the proper hose length to allow slack between
connection points. Hoses may vary in length by +2%
to -4% under pressure.
5. Refer to Table 1. Do not exceed the minimum bend
radius for the hose selected. Exceeding the minimum
bend radius may cause the hose to collapse, which
reduces water ow rate. Install an angle adapter to
avoid sharp bends in the hose when the radius falls
below the required minimum.
Insulation is not required on loop water piping except
where the piping runs through unheated areas, outside
the building or when the loop water temperature is
below the minimum expected dew point of the pipe
ambient conditions. Insulation is required if loop water
temperature drops below the dew point (insulation is
required for ground loop applications in most climates).
Pipe joint compound is not necessary when Teon®
thread tape is pre-applied to hose assemblies or when
ared-end connections are used. If pipe joint compound
is preferred, use compound only in small amounts on
the external pipe threads of the tting adapters. Prevent
sealant from reaching the ared surfaces of the joint.
Note: When anti-freeze is used in the loop, insure that it
is compatible with the Teon tape or pipe joint compound
that is applied.
Maximum allowable torque for brass ttings is 30 ft-lbs
[41 N-m]. If a torque wrench is not available, tighten
nger-tight plus one quarter turn. Tighten steel ttings
as necessary.
Optional pressure-rated hose assemblies designed
specically for use with Heat Controller units are available.
Similar hoses can be obtained from alternate suppliers.
Supply and return hoses are tted with swivel-joint ttings
at one end to prevent kinking during installation.
Refer to Figure 11 for an illustration of a typical supply/
return hose kit. Adapters secure hose assemblies to the
unit and risers. Install hose assemblies properly and
check regularly to avoid system failure and reduced
service life.
A backup wrench is required when tightening water
connections on HB series to prevent water line damage.

Water-Loop Heat Pump Applications
Commercial Water Loop Applications
Commercial systems typically include a number of
units connected to a common piping system. Any unit
plumbing maintenance work can introduce air into the
piping system; therefore air elimination equipment is
a major portion of the mechanical room plumbing. In
piping systems expected to utilize water temperatures
below 60°F [16°C], 1/2” (13mm) closed cell insulation is
required on all piping surfaces to eliminate condensation
(extended range units required). Metal to plastic threaded
joints should never be used due to their tendency to leak
over time. A backup wrench must be used for HB series
equipment ttings.
Teon tape thread sealant is recommended to minimize
internal fouling of the heat exchanger. Do not over tighten
connections and route piping so as not to interfere with
service or maintenance access. Hose kits are available
from Heat Controller in different congurations as shown
in Figure 12 for connection between the unit and the
piping system.
The piping system should be ushed to remove dirt,
piping chips, and other foreign material prior to operation
(see “Piping System Cleaning and Flushing Procedures”
in this manual). The ow rate is usually set between 2.25
and 3.5 gpm per ton [2.9 and 4.5 l/m per kW] of cooling
capacity. Heat Controller recommends 3 gpm per ton
[3.9 l/m per kW] for most applications of water loop heat
pumps. To insure proper maintenance and servicing, P/T
ports are imperative for temperature and ow verication,
as well as performance checks.
Water loop heat pump (cooling tower/boiler) systems
typically utilize a common loop, maintained between 60 -
90°F [16 - 32°C]. The use of a closed circuit evaporative
cooling tower with a secondary heat exchanger between
the tower and the water loop is recommended. If an
open type cooling tower is used continuously, chemical
treatment and ltering will be necessary.

Water Temperature Cutout Selection” in this manual). NOTE:
Low water temperature operation requires extended range
equipment.

Ground-Loop Heat Pump Applications
Pre-Installation
Prior to installation, locate and mark all existing
underground utilities, piping, etc. Install loops for new
construction before sidewalks, patios, driveways, and other
construction has begun. During construction, accurately
mark all ground loop piping on the plot plan as an aid in
avoiding potential future damage to the installation.
Piping Installation
The typical closed loop ground source system is shown
in Figure 13. All earth loop piping materials should be
limited to polyethylene fusion only for in-ground sections
of the loop. Galvanized or steel ttings should not be
used at any time due to their tendency to corrode. All
plastic to metal threaded ttings should be avoided due
to their potential to leak in earth coupled applications. A
anged tting should be substituted. P/T plugs should be
used so that ow can be measured using the pressure
drop of the unit heat exchanger.
Earth loop temperatures can range between 25 and
110°F [-4 to 43°C]. Flow rates between 2.25 and 3 gpm
per ton [2.41 to 3.23 l/m per kW] of cooling capacity is
recommended in these applications.
Test individual horizontal loop circuits before backlling.
Test vertical U-bends and pond loop assemblies prior to
installation. Pressures of at least 100 psi [689 kPa] should
be used when testing. Do not exceed the pipe pressure
rating. Test entire system when all loops are assembled.
Flushing the Earth Loop
Upon completion of system installation and testing, ush
the system to remove all foreign objects and purge to
remove all air.
Antifreeze
In areas where minimum entering loop temperatures drop
below 40°F [5°C] or where piping will be routed through
areas subject to freezing, antifreeze is required. Alcohols
and glycols are commonly used as antifreeze. Freeze
protection should be maintained to 15°F [9°C] below the
lowest expected entering loop temperature. For example,
if 30°F [-1°C] is the minimum expected entering loop
temperature, the leaving loop temperature would be 25 to
22°F [-4 to -6°C] and freeze protection should be at 15°F
[-10°C]. Calculation is as follows:
30°F - 15°F = 15°F [-1°C - 9°C = -10°C].
All alcohols should be premixed and pumped from
a reservoir outside of the building when possible or
introduced under the water level to prevent fumes.
Calculate the total volume of uid in the piping system.
Then use the percentage by volume shown in table
2 for the amount of antifreeze needed. Antifreeze
concentration should be checked from a well mixed
sample using a hydrometer to measure specic gravity.
CAUTION! The following instructions represent industry
accepted installation practices for closed loop earth coupled
heat pump systems. Instructions are provided to assist the
contractor in installing trouble free ground loops. These
instructions are recommendations only. State/provincial
and local codes MUST be followed and installation MUST
conform to ALL applicable codes. It is the responsibility of
the installing contractor to determine and comply with ALL
applicable codes and regulations.
