VPRC/VPRH Vertical Packaged Air Conditioner/Heat Pump
• Specifications and Performance •
General Product Information
Product description
• Condensate removal
–– VPRC/VPRH 09, 12, 19 & 24 — The outdoor blower incorporates a condensate slinger ring. Base pans are designed to
accommodate a field-installed drain stub kit if necessary. See
field installed accessories.
–– VPRC/VPRH 18, 30 & 36 require an internal drain system.
Models VPRC/VPRH 18 are supplied standard with an
overflow drain stub kit for field installation.
–– VPRC/VPRH 30-36 outdoor coil side drain stub is integral
to the base pan, and allows easy connection of the drain line.
• Microprocessor control board
–– Universal control board is used in straight cool electric resistance heat, hydronic heat (models 09–24 only), or cooling/
heat pump applications
–– Random start timer prevents multiple units from simultaneous start-ups
–– Fan purge — fan remains on for 60 seconds after heat/cool
call is satisfied
–– Anti-short-cycle compressor protection prevents the compressor from rapid cycling
–– Freeze protection — prevents evaporator coil freeze up,
improving compressor reliability
–– Low ambient lockout prevents compressor operation in outdoor temperatures less than 40°F (4.4°C)
–– Test operation — all timers are temporarily suppressed to
allow ease of testing or troubleshooting
–– Control board LED provides self-diagnostic troubleshooting
codes (see Sequence of Operation, page 9)
The VPRC/VPRH 09–36 single package vertical air conditioner
(SPVAC) and heat pump (SPVHP) creates new options in layout and
space utilization. The VPRC/VPRH 09–36 offers low cost operation
and quiet, comfortable air distribution, especially when used in multiroom suites, apartments, health care facilities, and homes.
Each system utilizes environmentally-friendly R-410A refrigerant,
and is supplied with a custom wall sleeve and outdoor louver. The
cabinet is constructed with 20 gauge galvanized steel with a G-90U
corrosion-resistant rating. The insulated top-discharge indoor compartment provides quiet, ducted, conditioned air delivery to other
room location(s).
Framed into a concealed closet enclosure for low operating sound
levels, the VPRC/VPRH vertical discharge allows ducting to the top
of the room(s) for superior air circulation and distribution.
All VPRC/VPRH models can be applied in non-ducted return air
applications. The VPRC/VPRH 30-36 can also be applied in ducted
return air applications.
The VPRC/VPRH offers an economic benefit when used in a multiroom suite by supplying conditioned air to more than one room without the need to install additional units. This is also a design advantage
since other rooms will not need an exterior wall to accommodate
additional units.
VPRH models are limited-range heat pumps — heat pump operation will cease at approximately 40°F (4.4°C) outdoor temperature.
Utilizing the electric resistant heat option or the hydronic heat option
is recommended if the heating load of the application will require the
unit to operate in outdoor ambient temperatures below 40°F (4.4°C).
Factory-installed options:
• Supplemental electric heat — see heat options in Figure 1

Features
Hydronic heat operation (optional)
Emergency heat (optional)
NOTE
An optional factory-supplied, field-installed hydronic heat package
is available. With the thermostat system switch set to heat and the
setpoint temperature above room temperature, the hydronic valve
will open allowing water to flow through the coil. The indoor fan
will also switch on and warm air will flow from the unit. Heating will
continue as long as the setpoint remains above room temperature.
Place the setpoint temperature below room temperature. The hydronic
valve will close and indoor fan will switch off after the sixty-second
purge time has elapsed. The hydronic valve is a 24vac normally open
valve. Should power be lost to the unit, the valve will default to the
open position.
VPRH units
ECR International recommends using a factory-supplied,
field-installed two-stage thermostat with heat pump
units (VPRH) equipped with electric resistance heat option. In the event of heat pump system failure, the two-stage
thermostat will automatically switch the unit’s control from
heat pump mode to electric heat mode.
If a single-stage thermostat is used and the heat
pump system fails, it is possible to manually force the
control board into electric heat mode.
VPRC units
Use a single-stage heat/cool thermostat, available as a
factory option.
The hydronic package is equipped with a thermostat (freeze-stat) that
is designed to prevent the hydronic coil from freezing. At 35°F (1.7°C)
the thermostat will switch open the hot water valve to prevent the coil
from freezing. At 50°F (10°C) the thermostat will reset. If the room
thermostat is not calling for heat, the valve will close. The freeze stat
is factory preset.
Anti-short-cycle timer (standard)
This feature prevents compressor short cycling. It also prevents
multiple units from starting simultaneously after a power outage.
This delay-on-break feature ensures that the compressor remains off
between cycles until the three-minute time delay period has elapsed,
allowing system pressures to equalize before restarting.
Coil freeze protection (standard)
This feature prevents the coil from freeze up in the cooling mode. Coil
freeze up can occur due to a dirty air filter, low refrigerant charge or
low room or outdoor temperatures. This in turn can cause compressor
damage. Should a freeze condition be detected, the compressor and
condenser fan will be switched off for a minimum of three minutes
and until the freeze condition is satisfied. During this time the indoor
fan will continue to run to aid in the defrost process.
Random start timer (standard)
Thermostatic drain valve
Carrier 50QT/ET replacement (optional)
The random start feature, initiated after a power failure, will add a
random time delay (from 5 to 120 seconds) to the three-minute anti
short cycle time following a power outage. This will stagger the starting of multiple units in a single facility allowing a building to slowly
go back on line when power is restored.
(standard — VPRH 09, 12, 19 & 24 only)
The VPRC/VPRH 09–18 can be used to replace the Carrier 50QT/
ET series PTAC and older vertical PTAC’s from other manufacturers . Refer to Figure 1 on page 4 “Options” when ordering a Carrier
50QT/ET replacement. Model 18 can be field-modified with a simple
extension of the outdoor air baffle. Consult your ECR International
sales representative for more information.
Heat pump units are equipped with a thermostatic drain valve that
will open when outdoor temperatures fall below 50°F (10°C). This
keeps the base pan free of condensate water where it may otherwise
freeze during colder outdoor temperatures.

• Specifications and Performance •
Sequence of Operation
Initial power-up or power restoration
Cooling operation
When power is applied to the unit, either for the first time or after a
power failure, the board will initialize itself. During the initialization,
LED1 will be lit continuously for approximately 5 seconds.
If the room temperature is above the thermostat setting, the reversing
valve (VPRH only) will be energized. The compressor and outdoor
fan will start provided the Anti-Short Cycle Timer has timed out from
the initial power-up, power restoration or a previous compressor on
cycle. Operation will continue until the room temperature satisfies
the thermostat. Once the room temperature falls below the set point
by 3 ºF (2 ºC), the compressor, outdoor fan motor and reversing valve
(VPRH only) will de-energize.
Following initialization, a random-start timer is initiated. This timer
adds a randomly selected 5-120 seconds to the start-up sequence,
reducing the possibility of multiple units starting at the same time.
Once the random start timer has expired, a 180-second anti-shortcycle timer is initiated. LED1 blinks a two-flash code. (The antishort-cycle timer prevents the compressor from rapid cycling.) After
the anti-short-cycle timer expires, LED1 blinks a one-blink code,
indicating normal operation.
Figure 3
As soon as the compressor is de-energized, the anti-short-cycle timer
will be initialized and will prevent the compressor from starting again
for another 180 seconds. While the anti-short-cycle timer is active,
the LED1 is set to blink a two-flash code. After the anti-short-cycle
timer expires, the LED1 is set to blink a one-blink code, indicating
normal operation.
Indicator LED1
Mechanical heating (VPRH only)
If the outdoor coil temperature remains above 25 ºF (-4 ºC), the
compressor and outdoor fan will start provided the anti-short-cycle
timer has timed out from the initial power-up, power restoration or a
previous compressor on cycle. Operation will continue until the room
temperature satisfies the thermostat.
LED1
Once the room temperature rises above the set point by 3 ºF (2 ºC),
the compressor and outdoor fan motor will de-energize.
As soon as the compressor is de-energized, the anti-short-cycle timer
will be initialized and will prevent the compressor from starting again
for another 180 seconds. While the anti-short-cycle timer is active,
LED1 blinks a two-flash code. After the anti-short-cycle timer expires,
LED1 flashes a one-blink code, indicating normal operation.
Auxiliary heating
If the outdoor coil temperature falls to 25 ºF (-4 ºC) or below for
180 seconds at anytime during a heating call, the compressor and
outdoor fan motor will be de-energized and auxiliary heat will be
energized. The anti-short-cycle timer will be initiated, prohibiting
compressor operation for 180 seconds. LED1 will flash a three-blink
code, indicating auxiliary heat operation. Heating operation with
auxiliary heat will continue until the outdoor coil sensor reaches
50 ºF (10 ºC).
Fan operation
Some thermostats are equipped with an auto/on fan switch.
• When this switch is placed in the on position the indoor fan will
run continuous.
• When the switch is in the auto position the indoor fan will cycle
with the call for heating or cooling.
Hydronic heating
• Fan purge (auto mode only) — after the room thermostat has
been satisfied, the purge feature allows the indoor fan to remain on
for an additional 60 seconds. This increases efficiency by pulling
the remaining energy from the unit.
With a call for heat, a signal from the processor board will activate
the water or steam valve and the indoor fan. The signal to the water
or steam valve will continue until the room temperature rises above
the set point by 3 ºF (2 ºC).

Choosing a thermostat
All field wiring must be done in accordance with the National Electrical Code, ANSI/NFPA 70–latest edition, and local codes (in Canada
— CSA C22.1 Canadian Electrical Code Part 1 and local codes).
ECR International offers your choice of a single-stage or two-stage
mercury-free thermostat that is compatible with all models of the
VPRC/VPRH. (Use a two-stage thermostat for VPRH units equipped
with the electric heat option.)
Check the VPRC/VPRH ratings. The installer is responsible for ensuring that VPRC/VPRH units are installed in accordance with all
applicable national and local codes. Check the rating plate for circuit
ampacity. Size the breaker(s) or fuse size(s) accordingly.
• RetroAire™ thermostats have digital readout with a temperature
control range from 45°F (7°C) to 90°F (32°C).
• Use only HACR type breakers or time delay fuses.
• When using a thermostat other than one offered by ECR International, use ONLY a 24v heat/cool thermostat.
• Select the proper wire for the breaker or fuse size used.
Cooling-only with electric or hydronic heat
(VPRC only)
• Some units require more than one power supply.
• Select a thermostat that is compatible with a cooling/electric
heat system.
• If a plug and receptacle are used, check for proper fit.
• Check the nameplate and wiring diagram for further instructions
and wire connections.
• The thermostat should have “R”, “Y”, “W” and “G” terminals.
• Each unit is equipped for a 24v wall thermostat connection.
(VPRH only)
Heat pump with electric heat
Single-stage thermostat
NOTICE
VPRC/VPRH units are wired for 230v primary voltage
from the factory. The transformer must be rewired by the
installer if the jobsite voltage is 208v.
Power cord with integral safety protection
All VPRC/VPRH units that are cord connected to the power supply
are equipped with a power cord with an integral sensor that:
Select a thermostat that is compatible with a cooling/single stage
heat/heat pump system.
• The thermostat should have “R”, “Y”, “O” and “G” terminals.
RetroAire™ units are single stage heating only.
• The electric heat and heat pump will not operate simultaneously.
Two-stage thermostat
• Provides personal shock protection.
A two-stage heat pump thermostat can be used with VPRH units.
• Provides arcing and fire prevention.
• See the wiring diagram for connections.
• Senses any damage in the line cord and disconnects power before
a fire can occur.
Tested in accordance with Underwriters Laboratories, the cord set
also offers a unique “passive” operation, meaning the unit does not
require resetting if main power is interrupted.
• VPRH units are designed to operate as single stage heat pumps —
they will alternate between heat pump and electric heat to meet
the heat demand.
Disconnect switch (optional)
The disconnect switch ensures that all power to the control box is
disconnected for servicing.

• Specifications and Performance •
Chassis and wall sleeve
Provide proper clearances
Rough openings
NOTE: ECR International recommends installing the unit before any
carpentry work is started for the enclosure.
It is very important for proper air flow and sound levels that a minimum clearance of 4 inches, 102 mm (models 09–18) or 6 inches,
152 mm (models 24–36) between the enclosure and the chassis be
maintained (see Figure 8).
For designed performance, sound levels, and service, maintain a minimum of 6 inches (152 mm) on both sides and front for non-ducted
return air applications only.
Ducted return air applications only require minimal spacing for service
requirements.
Consult ECR International’s Sales Department if these minimums can
not be met. Depending on the application and return air introduction,
some re-configuration can probably be accommodated.
Minimum and maximum operation conditions must be observed
to ensure maximum system performance with minimum service
required.
Access opening — The access opening must allow for the unit to be
inserted for installation. Provide at least the minimum opening dimensions below. (See Table 12, page 19, for dimensions of the opening
when using the option return access panel assembly.)
Figure 9
Wall sleeve rough opening — It is very important that the rough
opening in the wall for the wall sleeve and louver be the correct dimension and in the exact position necessary for installation.

See Figure 10, Page 25 and Figure 13, Page 27 for details of the platform
and wall sleeve installation. The platform height must make the bottom
of the VPRC or VPRH chassis flush with the bottom inside edge of
the wall sleeve. This means that the platform surface must be ½ inch
(13 mm) ABOVE the bottom of the wall sleeve rough opening.
The platform dimensions above will allow the chassis base pan to align
with the bottom of the wall sleeve.
Air filter
All models must have an air filter installed prior to operation. Use
the chassis-mounted air filter supplied with the unit unless using the
optional return air access panel. For these applications, remove and
discard the filter from the unit and install the access panel with the
supplied filter in place.

is located on the chassis opening unless the
optional return air access panel is used (for
these applications, the air filter is removed
from the chassis — a filter is installed on the
access panel).

Determine wall sleeve depth
Wall sleeve assembly
The wall sleeve depth must be suitable for the overall wall thickness.
It is critical that wall thickness be determined before ordering the
wall sleeve (Figure 10).
• Models 09–24 are supplied with a tabbed-assembly wall sleeve,
and must be field assembled.
• Wall sleeves for models 30–36 are factory assembled.
Consult factory for available wall sleeves.
• The minimum wall sleeve depth is for a 6½ inch (165 mm) overall
wall thickness, and available in ½-inch (13-mm) increments for
thicker walls.
• For wall thicknesses less than 6½ inches, the wall sleeve will penetrate into the room, and will require interior framing adaptations
for proper fit.
Determine openings and enclosure
Determine the access opening size, wall sleeve opening size and enclosure size per page 24.

Replacing Older RetroAire VPAC/VPHP30 Units
The VPRC/VPRH30 is larger than the VPAC/VPHP30. Ductwork changes are required. If replacing a VPAC/VPHP30
with a VPRC/VPRH30, RetroAire offers a transition wall sleeve and adapter (550002100) for the existing VPAC/
VPHP30 wall sleeve. This adapter adds 3.5” (89mm) to the depth of the unit and allows the use of the existing wall
sleeve and louver. If using this transition piece, be sure to maintain the minimum clearances required. The transition
adapter also requires the platform height to be increased by 3/8” (10mm).
