Installation and Operations Manual
Space and Location Requirements
For PTN models.
1. Owner’s Operating Instructions
The most important consideration which must be taken into account
when deciding upon the location of air-cooled equipment is the provision
for a supply of ambient air to the condensing unit. Ignoring this essential
requirement will result in higher condensing pressure and contribute
to poor operation or potential equipment failure. Units must not be
located in the vicinity of steam, hot air or fume exhausts. Adequate
air circulation through the condensing unit is critical to ensure proper
equipment operation. Improper installation can damage the unit and will
void the warranty. penthouse-style packaged units are designed
for indoor use only in ambient temperatures of 50°F to 100°F. The unit
cabinet is not approved for weather tight applications.
Another important consideration is that the unit should be mounted
away from noise sensitive spaces and must have adequate support to
avoid vibration and noise transmission into the building. Storage should
not be allowed on top of walk-in structure. Unit must not be enclosed
in an unventilated space.
Figure 1.
PTN models
Minimum 2" clearance from
opening to adjacent wall. No
storage is allowable on top of
walk-in structure.
IMPORTANT: Ventilation air
must be provided for the
condensing unit.
Structure must not be masked
to building ceiling, blocking air
ow to unit.
System Space and Location Requirements for
Side View
Allow 2 feet
clearance above
unit to remove
top panel and
to allow service
access.
Mounting rails
may be used to
attach unit to
ceiling.Throughbolts should
be insulated or
non-conductive
to prevent
sweating.
Recommended Unit Placement
Some general rules for the evaporator section placement which
must be followed are:
1. Ensure that the structural integrity of the box can
withstand the weight of the top mounted equipment.
2. The air pattern must cover the entire room.
3. NEVER locate the evaporator section over doors.
4. Location of aisles, racks, etc. must be known.
5. Never remove or unlock any panel cam-locks to
install top mounted equipment.
The size and shape of the storage will generally determine the type
and number of units to be used and their location.

Rigging
Rigging holes are provided on all medium and large cabinet
models. Caution should be exercised when moving these
units. To prevent damage to the unit housing during rigging,
cables or chains used must be held apart by spacer bars. The
mounting platform or base should be level and located so as
to permit free access of supply air.
Access Requirements
Provide adequate space at the compressor end of the unit for
servicing. Provide two (2) feet of space above unit for service.
Trim Ring Installation Detail
Mounting
The system requires an opening in the ceiling to the dimensions stated on page 3. Mounting rails are located at both
ends of the chassis. Mounting rails may be used to attach
unit to ceiling. Through-bolts should be insulated or nonconductive to prevent sweating. The chassis is weather
stripped around the air grille and will seal to the box roof.
The trim ring (shipped loose), when provided, should be
installed around the air diuser when secured with the
hardware provided. Be sure to adhere to your local standard
construction codes.

Refrigeration/Defrost Sequence of Operation
The sequence of operation varies depending on the model that has been installed. The three basic models are Low Temperature, Medium
Temperature, and High Temperature models. The particular model can be determined by the seventh digit of the model number. See Tables
1-3 for details and settings.
Control of the refrigeration and defrost system is provided by the Carel controller along with a space (box) temperature sensor and a coil
(defrost) temperature sensor. The controller will control on and o switching for the compressor, condenser fan motor(s) (cycles with the
compressor), evaporator fan motor(s) and electric defrost heaters for electric defrost.
The Carel controller is pre-programmed for all three applications. This is done with the use of the parameter list. The parameter list can be
changed by entering the Carel Controller and changing the “EZY” setting. See page 13.

Programming the PJEZC Carel
Electronic Controller
Reprinted with permission from Carel.
The Carel PJEZC control is a fully congurable electronic refrigeration
controller. The Top Mount packaged refrigeration system uses the
Carel controller on all three temperature designated models. The
models dier by a pre-programmed parameter list that is specic
for each application.
There are two levels of programming with the C controller. The rst
level can be accessed through the keypad. Set Point (st), Interval
between defrost (do), Maximum Defrost Duration (dP), and Dripping
Time (dd) are examples of rst level parameters. Second level
parameters can be accessed by entering a password. See “Modifying
Parameters” (page 15).
Installation and Removal
PANEL INSTALLATION FROM THE FRONT USING SCREWS
• The thickness of the fastening panel must not exceed 3 mm;
• Remove the front frame and make sure that the two catches
are in place (these must not protrude from the outline of the
drilling template). If necessary, unscrew the two screws. Do not
unscrew excessively, the screws must not be detached from the
front panel (phase 1);
• Insert the instrument in the opening in the panel and hold it in
position by the centre of the front panel (phase 1);
• Using the screwdriver, tighten the bottom screw 90°, the catch
must come out of its slot and click onto the panel, then tighten
until the front panel is secure; Do not over-tighten, when the
front panel is secured blocks simply make another ½ turn to
compress the gasket; If the catch does not click onto the panel,
unscrew the screw, applying pressure at the same time with
the screwdriver so that the catch moves back. Do not unscrew
too much, the head of the screw must not be raised from the
surface of the front panel (phase 2);
• Repeat the same operation for the top screw (phase 2);
• Apply the front frame (phase 3).
2. Controllers
* Do not over-tighten the screws.
DISMANTLING USING THE SCREWS FROM THE FRONT
• Unclip the front frame;
• Unscrew the bottom screw, at the moment the front panel
detaches from the panel keep pressure on the screw and
unscrew a further 90° to make the catch go back into its slot;
• Repeat for the top screw;
• Remove the instrument from panel, keeping it horizontal

Installation and Operations Manual
WARNING: When rst connected, easy is already on and
ready to be used. The instrument can be switched on from
a supervisor PC and via an external contact (setting A4=
5). The latter has priority over the other modes.
SET POINT SETTING DESIRED TEMPERATURE VALUE
The easy and easy compact devices control the desired temperature
(set point) inside the cabinet or cold room directly and dynamically.
To view and modify the set point:
• press SET for 1 s, the set value will start ashing;
• increase or decrease the value using UP or DOWN;
• press SET to conrm the new value.
2. Controllers
MANUAL DEFROST
Press DOWN for more than 3 s (activated only if the temperature
conditions are right).
CONTINUOUS CYCLE
Press UP+DOWN for more than 3 s (activated only if the temperature
conditions are right).
The continuous cycle is used to maintain refrigeration active in the
cabinet or cold room, regardless of the temperature inside the unit.
This may be useful for rapidly bringing the temperature below the
set point value.
RAPID DISPLAY OF THE TEMPERATURE READ BY THE OTHER
PROBES
Press the DOWN button to scroll the temperatures read by the
probes. Each time the DOWN button is pressed, the display will
show the name of the probe Pr1, Pr2 or Pr3 (only on the models with
3 inputs and with multifunction input congured as a probe) and
after 1 s the temperature measured by the selected probe will be
displayed.
To display the other probes, press DOWN again.
To return to the normal display, wait 3 s without pressing any buttons
(exit by timeout).
Temperature Display
The temperature displayed, the unit of measure and the decimal
resolution can be set according to the following parameters: /4, /5
and /6.
/4 : select probe displayed
Used to choose whether to display the temperature read by the
control probe (Probe 1), Probe 2 or the status of the multifunction
input (analogue or digital).
Parameter /4 selects the probe shown on the display, all the other
display and control modes remain unchanged.
IMPORTANT: the easy compact models can display up to 2 probes.
/5: select °C/°F
Denes the unit of measure used for temperature control.
/5=0 to work in °C
/5=1 to work in °F.
WARNING:
When changing from one unit of measure to the other, all
the values of the temperature parameters are modied to
the new unit of measure.
The max and min limits of the absolute temperature
parameters are the same for both °C that °F. The range of
temperatures allowed is therefore dierent between °C
and °F:
/6: disable decimal point
Used to enable or disable the temperature display with the resolution
to the tenths of a degree between -20 and + 20 (easy) or -10 and +10
(easy compact).
/6= 0 temperature displayed to the tenth of a degree;
/6=1 temperature displayed without the tenths of a degree.
NOTE: the decimal point is only disabled in relation to the reading
shown on the display (the calculations performed by the controller
remain unchanged).
Temperature Control
The following parameters are used to control the temperature: St,
r1, r2, r3, r4 and rd.
St: set point, r1 minimum value and r2 maximum value of the
set point
Parameter St determines the desired temperature to be maintained
inside the cabinet or cold room (set point). Parameters r1 (minimum
value) and r2 (maximum) set the range of temperatures for setting
the set point.
NOTE: the set point can be set by pressing the SET button (see par.
“Setting the set point (desired temperature value)”).
r3: select direct/reverse operation
Denes the operating mode of the device:
• r3=0: direct with defrost. Used to request the activation of the
compressor when the temperature measured by probe 1 rises
above the set point. This mode also includes defrost
• r3=1: direct without defrost
• r3=2: reverse without defrost. Used to request the activation of
the compressor when the temperature measured by probe 1
falls below the set point. This mode does NOT include defrost.

Rapid Parameter Set Selection (EZY)
The easy controller features the EZY parameter which is used to
quickly choose a list of parameters, with corresponding values, for
the control of the refrigeration system.
Table of Alarms and Signals
When an alarm is activated, the display shows the corresponding
message that ashes alternating with the temperature; if tted and
enabled, the buzzer and the alarm relay are also activated.
All the alarms have automatic reset (that is, they stop when
the causes are no longer present), except for alarm ‘CHt’ which
has manual reset (instrument on/o using the UP button or by
disconnecting the power supply).

Code
NOTE:
• to restore the selected rapid parameter set at any time, turn the
controller o and on again, while holding SET. The display shows
“CE” to indicate that the selected rapid set (EZY= 1, 2, 3) has again
overwritten the operating parameters, thus restoring the original
set of parameters;
• to restore all the parameters and return to the original default
values (factory settings), turn the controller o and on again
while holding DOWN and SET, until the display shows “CF”. Use
this procedure with extreme care, as it may compromise the
fundamental control settings;
• EZY=0 brings no change;
Pressing the SET button mutes the buzzer, while the
code displayed and the alarm relay only go o when
the causes of the alarm have been resolved. The alarm

Installation and Operations Manual
Description of the Main Signals
and Alarms
LED ashing
The activation of the corresponding function is delayed by a timer,
awaiting an external signal or disabled by another procedure that
is already in progress. e.g. if is a continuous cycle in progress and a
defrost is called, the latter will remain pending until the end of the
continuous cycle, and the corresponding LED (defrost) will ash.
E0 steady or ashing
Control probe error:
2. Controllers
• probe not working: the probe signal is interrupted or shortcircuited;
• probe not compatible with the instrument;
The alarm signal E0 is steady if it is the only active alarm (the
temperature value is not displayed), while it ashes if other alarms
are active or the second probe is displayed.
E1 ashing
Evaporator probe or food conservation probe error:
• probe not working, the probe signal is interrupted or shortcircuited;
• probe not compatible with the instrument;
E2 ashing
Ed ashing
The last defrost ended after exceeding the maximum duration
rather than when reaching the end defrost set point.
• check parameters dt, dP and d4;
• check the eciency of the defrost.
The message disappears when the next defrost ends correctly.
dF ashing
Defrost running:
• this is not an alarm signal, but rather a message that the
instrument is running a defrost. Only shown if d6= 0.
EtC ashing
Internal clock error.
Data Error
In certain operating conditions, the instrument may detect errors in
the data saved. These errors may compromise the correct operation
of the instrument. If the microprocessor detects a data saving error,
the display shows the message “EE”.
If the fault persists, the controller needs to be replaced. If, on the
other hand, the message disappears, it can continue to be used.
When “EE” error occurs frequently and/or remains for some time, the
controller should be checked, as the original precision may not be
guaranteed.
Condenser probe or food conservation probe error:
• probe not working, the probe signal is interrupted or shortcircuited;
• probe not compatible with the instrument;
IA ashing
Immediate or delayed alarm from multifunction digital input:
• check the multifunction input and parameters A4 and A7.
LO ashing
Low temperature alarm. The probe has measured a temperature
lower than the set point by a value that exceeds parameter AL:
• check parameters AL, Ad and A0.
The alarm is automatically reset when the temperature returns
within the set limits (see parameter AL).
HI ashing
High temperature alarm. The probe has measured a temperature
higher than the set point by a value that exceeds parameter AH.
• check parameters AH, Ad and A0.
The alarm is automatically reset when the temperature returns
within the set limits (see parameter AH).
EE displayed during operation or on power-up
unit parameter reading error. See Data errors.
EF displayed during operation or on power-up
operating parameter reading error. See Data errors.

Modifying the Parameters
PARAMETER NAVIGATION
The operating parameters, modiable using the keypad, are divided
into two types: frequent (type F) and conguration (type C). Access
to the latter is protected by password (default= 22) to prevent
accidental or unauthorized modications.
Accessing the type F parameters:
• press the SET button for more than 3 s (if there are active alarms,
mute the buzzer), the display shows the parameter code ‘PS’
(password);
• use the UP and DOWN buttons to scroll the parameters. The LED
corresponding to the category of parameters will be on;
• press SET to display the value associated with the parameter
increase or decrease the value using the UP or DOWN button
respectively;
• press SET to temporarily save the new value and display the
parameter again;
• repeat the procedure for any other parameters that need to be
modied;
• press the SET button for more than 3 s to permanently save the
parameters and exit the parameter setting procedure.
Accessing the type C parameters:
• press the SET button for more than 3 s (if there are active alarms,
mute the buzzer), the display shows the parameter code “PS”
(password);
• press the SET button to access the password setting;
• use the UP and DOWN buttons to scroll the numbers until
displaying “22” (password to access the parameters);
• press the SET button to conrm the password;
• use the UP and DOWN buttons to scroll the parameters. The LED
corresponding to the category of parameters will be on (see
Table below);
• press SET to display the value associated with the parameter
increase or decrease the value using the UP or DOWN button
respectively;
• press SET to temporarily save the new value and display the
parameter again;
• repeat the procedure for any other parameters that need to be
modied;
• press the SET button for more than 3 s to permanently save the
parameters and exit the parameter setting procedure.
Warnings:
If no button is pressed for 60 s, all the changes made to
the parameters, temporarily saved in the RAM, will be
cancelled and the previous settings restored.
The dAY, hr, Min parameters are not restored, as these are
saved instantly when entered.
If power is disconnected from the instrument before
saving the settings (pressing the SET button for 3 s), all the
changes made to the parameters and temporarily saved
will be lost.
Setting the Default Parameters
Warnings:
Running this procedure overwrites any custom parameter
settings.
To reset the default parameters:
• disconnect power from the instrument;
• reconnect power while holding the SET and DOWN buttons;
• the display will show the message “CF”;
• after a few seconds the instrument starts operating with the
default conguration. Any dierent parameter settings will
need to be updated.

defects in material or workmanship, under normal use and service
for a period of two (2) years from date of original installation, or
thirty (30) months from date of shipment by Heatcraft Refrigeration
Products LLC, whichever rst occurs. Service Parts, for product out

order found to Heatcraft Refrigeration Products LLC's satisfaction to
be defective upon examination at Heatcraft Refrigeration Products
LLC's factory will, at Heatcraft Refrigeration Products LLC's option,
be repaired or replaced and returned to Buyer via lowest common

return of a defective product to Heatcraft Refrigeration Products LLC's
plant, freight prepaid, by Buyer, correction of such defect by repair
or replacement, and return freight via lowest common carrier, shall
constitute full performance by Heatcraft Refrigeration Products LLC
of its obligations hereunder.
Hermetic compressors furnished by Heatcraft Refrigeration Products
LLC are subject to the standard warranty terms set forth above, except
that motor compressor replacements or exchanges shall be made
through the nearest authorized wholesaler of the motor compressor
manufacturer (not at Heatcraft Refrigeration Products LLC's factory)
and no freight shall be allowed for transportation of the motor
compressor to and from the wholesaler. The replacement motor
compressor shall be identical to the model of the motor compressor
being replaced. Additional charges which may be incurred throughout
the substitution of other than identical replacements are not covered
by this warranty.
The foregoing is in lieu of all other warranties, express or implied,
notwithstanding the provisions of the uniform commercial code, the
Magnuson-Moss Warranty-Federal Trade Commission Improvement
Act, or any other statutory or common law, federal or state.
Heatcraft Refrigeration Products LLC makes no warranty expressed or
implied, of tness for any particular purpose, or of any other nature
whatsoever, with respect to products manufactured or sold by
Heatcraft Refrigeration Products LLC hereunder, except as specically
set forth above and on the face hereof. It is expressly understood and
agreed that Heatcraft Refrigeration Products LLC shall not be liable to
buyer, or any customer of Buyer, for direct or indirect, special, incidental,
consequential or penal damages, or for any expenses incurred by
reason of the use or misuse by Buyer or third parties of said products.
To the extent said products may be considered "Consumer Products,'
as dened in Section 101 of the Magnuson-Moss warranty-Federal
Trade Commission Improvement Act, Heatcraft Refrigeration Products
product, except Service Parts, manufactured by Heatcraft

LLC makes no warranty of any kind, express or implied, to "Consumers,"
except as specically set forth above and on the face hereof.
This equipment is designed to operate properly and produce the
rated capacity when installed in accordance with good refrigeration
industry practices.
The following conditions should be adhered to when installing this
unit to maintain the manufacturers warranty:
(a) The power supply to the unit must meet the
following conditions:
A. Three phase voltages must
be +/- 10% of nameplate
ratings. Single phase must be
within +10% or -5% of
nameplate ratings.
B. Phase imbalance cannot
exceed 2%.
(b) All control and safety switch circuits must be
properly connected according to the wiring
diagram.
(c) The factory installed wiring must not be
changed without written factory approval.
Optional Three-Year Extended Compressor Warranty
The Equipment Dealer may purchase for the Owner at the time of the
original invoice of the equipment a Three-Year Limited Replacement
Compressor Warranty. This entitles the owner to be reimbursed for the
cost of a replacement compressor, during the third through fth year
of the life of the compressor.
The warranty program functions similarly to the standard warranty
oered. When a compressor failure occurs and the unit is exchanged
"over the counter" at the authorized wholesaler outlet a salvage credit
is issued along with the invoice for the new compressor. Return copies
of both the credit and invoice to the Equipment Dealer along with
the model and serial number of the condensing unit. The Equipment
Dealer will process this claim with the Manufacturer and subsequently
reimburse the Owner for the cost of the new compressor.
This warranty covers the actual compressor only and does not extend
to any labor, trip charges, crane rental, taxes or additional parts,
refrigerant or processing/handling charges required to make the
unit operational.
