General
General description
The model BCH heat pump is an air to air type of equipment
that provides air conditioning in summer and in winter by
reversion of its operating cycle.
It can be located either indoors or outdoors since it is
protected to withstand weathering and the centrifugal fans
allow the connection of ductwork.
It is delivered totally equipped, factory tested and ready for
the incorporation of the electric heater accessory, indoor or
for ductwork.
Designed to achieve an important energy saving and a long
operating life by the incorporation of an electronic control
module.
Temperature adjustment is achieved by means of the 24 VAC
ambient thermostat.
Nomenclature
Balance point
Since the heat pump operates by extracting heat from the
outdoor air, it is possible that sometimes this temperature is
so low that the extracted heat is insufficient to satisfy the
heating demand. For these conditions the electronic module
has six balance points (between - 4 and 14 °C), one of which
will be adjusted during the start-up. Below this temperature
the supplementary electric heater will come into operation.
The heat pump will nevertheless continue to operate with a
COP greater than that of the electric heaters until the outdoor
temperature drops below -20°C.
Below this temperature the heat pump will automatically stop
operating and will only use the electric heaters to warm the
space. This prevents the compressor from operating with
very high compression ratios that will shorten its operating
life.
Compressor safeties
A temperature sensing element protects the compressor
against too high discharge temperatures.
A pressure cutout stops the compressor when the discharge
pressure is too high.
It also actuates in case of a refrigerant leak or because of an
insufficient air flow across the coils.
Defrost control
The defrost cycle starts after a period, set at will, of 30, 60 or
90 minutes after start or last defrost cycle and the liquid line
temperature is -5°C or less.
Start timer
It prevents frequent stops and starts. After stopping, the unit
does not start again until 2 or 5 minutes, set at will, have
elapsed.
Control panel
The control of the BCH heat pump operation is done by
means of thermostat that allows the following:
1- Setting of the desired temperature.
2- Automatic availability of heating or cooling as desired.
3- Control that the operation of the indoor fan be continuous
or intermittent depending on the operation of the compressor.
4- Operate the electric heaters shutting down the rest of the
unit.
Technical specifications
Mechanical specifications
Compressor
Of the vertical hermetic type, mounted on shock absorbent
blocks, equipped with a low consumption motor.
It is delivered with a charge of a special oil that prevents foam
formation and with an electric oil heater.
Compressor oil heater
Keeps the crankcase oil hot to ease starts and prevent the oil
from being carried away from compressor.
Suction accumulator
Connected to the suction tube of the compressor it protects
it against liquid strokes, preventing the oil from coming out of
the compressor.
Suction exchanger
Formed by the suction and liquid tubes of the circuit, protects
the compressor by preventing the liquid refrigerant from

reaching it. Also it increases the efficiency of the system.
Coils
Of large heat transfer area, made of copper tubes and
aluminum fins.
They are located inside the casing and are therefore protected from being damaged during transport and installation.
Fans indoor and outdoor fan
Centrifugal type with direct drive motor.
These fans develop sufficient pressure for the installation of
ducts and optional accessories.
Casing
Built of steel sheet with aluminum-zinc protection, with
primer and powder epoxy finish to allow its installation outdoors.
Supplementary electric heaters
Of the air exposed wires type that allow a rapid heat dissipation, avoiding the thermal inertia that could affect components.

Installation instructions
General
The BCH heat pumps are delivered as factory charged and
tested packaged units. Designed to be installed with ducts,
on terraces, rooftops, in lofts or basements.
Protection of the environment
Packing
Packing is made of recyclable material. The disposal of same
should be carried out in accordance with the regulations on
selective residue disposal established by the local authorities.
Disposal of the unit
When dismantling after a long service life, its components
should be ecologically salvaged. The cooling circuit is full of
HCFC-22 refrigerant which should be salvaged and, finally,
returned to the gas manufacturer for recycling.
Oil will remain in the airtight compressor so, it will be returned
along with the sealed circuit.
The air conditioning unit will be deposited wherever established by the local authorities for its selective disposal.
Warning signs
The following signs indicate the presence of potentially
dangerous conditions for the users or service personnel.
Whenever found on the unit itself, keep in mind the warning
indicated by each one.
Transport
The units should always be transported in a vertical position
to prevent oil from leaking out of the compressor. If for some
reason the unit must be temporarily moved from this position,
the time that it rests in a different position should be kept to
a minimum.
Location
The unit should be placed in a location that leaves a permanent access for maintenance service, either through the side
panels, or top cover.
They can be installed in any outdoor location. If installed
indoors in basements, lofts, etc., the ducts for outdoor air
intake and exhaust should be connected.
When the unit is installed indoors, consideration should be
given to the great quantity of water condensed by the outdoor
coil during winter operation, that must be drained through the
drain pipe.
Occasionally, when the operating cycle is reversed in winter
to remove the frost that forms on the coil, the air could carry
water droplets. This should therefore be kept in mind when
selecting the place of installation and also the possibility of
Attention: It is compulsory to read the
instructions prior to any handling.
This sing indicates an electrical risk or
danger.
Attention: Not to touch the hot surfaces.
Attention: The unit has remote control
system and can start automatically. Two
minutes prior to having access to the
interior, the power supply should be
disconnected so as to avoid any contact
with the fan turbine in operation.
Attention: Fan in operation.
Page 12
12
the drain pipe becoming clogged by dust, dirt or some other
material should be foreseen.
Attaching unit
From the roof
The unit will be fastened to the roof by four M-10 bolts as
shown in figure. For this type of installation the use of
vibration isolators is recommended.
When fastening unit care should be taken that it is completely
horizontal or slightly tilted towards the drain to avoid the
dripping of condensed water (use an air bubble level).
The connections to the unit should be done with copper tube
of 22 mm O.D.
Resting on the ground
If unit is placed outdoors on the ground, it should be raised on
supports to avoid the possibility that snow accumulation
blocks the air intakes.
Drain connections
The pan drain lines of the indoor and outdoor units must be
installed with a water trap with a minimum level difference of
75 mm between the connection to the unit and the line after
the water trap (see figure). This is necessary to avoid the fan
generated negative pressure preventing the drain pan from
draining.
The drain line should have a minimum slope of 20 cm per
meter length.
Attention:
When the heat pump operates under outdoor temperatures
below 5°C, the drain tube could become obstructed by ice
formation.
If the unit is located outdoors, the possibility of this happening
should be prevented by installing an electric heater on the
drain connection and wiring it according to the corresponding
diagrams.
Clearances
Free space must be allowed for in the installation of each unit
for:
a) Air intake and discharge from the outdoor unit.
b) Connecting the drainage and wiring pipes.
c) Air ducts.
d) Maintenance servicing.
e) Connecting up of the electrical supply.
The minimum distances, indicated in the overall dimensions
diagrams, must always be respected with regard to possible
obstacles to the free circulation of air, or the operator's work.
Air ducts
1) Air ducts should be connected to the unit isolated by a
sleeve of a flexible, preferably non-combustible material,
to prevent transmission of the unit's own vibration. If
ducts are made from a flexible material they will not
transmit vibration.
2) It is advisable to install a damper in every discharge duct,
thus making possible a correct balance of the system.
3) Allow for an easy access to the air filters for replacement
and cleaning.
4) If the air discharge of the outdoor coil is done through
ducts, it is advisable that the first meter section be of
galvanized sheet to avoid corrosion produced by water
droplets carried by the air.
It is very important to take the maximum cara with the support of the
internal unit when hanging it from a false ceiling. Make sure that the
false ceiling is strong enough to withstand the weight of the unit. Before
hanging the unit, check the strength of every suspension bolt installed.
Attention: It is essential to use all fixing points on the unit.
The BCH-7, 10, 12, 15 and 20 have 4 fixing points.
The BCH-25 and 30 have 6 fixing points.

Electrical installation
In every case the established national regulations should
be applied.
Each heat pump is delivered with a control box, to which the
power supply will be connected across a fused main disconnect switch or automatic circuit breaker.
The electric heater, if available, should be installed with
power supply line and switches independent from those of
the heat pump.
Start-up procedure
a) Connect the power supply cable and earth to the
corresponding boards on the controls box.
b) Give power to the auxiliary control line at 220/240.1.50.
c) Connect the room thermostat line to 24 V on the boards
provided in the heat pump.
d) Before start-up connect the main switch or automatic
circuit breaker to supply power to the electric oil heater in
the compressor crankcase.
Compressor should not be started before a minimum
of 8 hours have passed.
This is necessary to evaporate any liquid refrigerant that
could have mixed with the compressor oil.
Loose cables can cause overheating of the connectors or an
inadequate operation of the unit. Fire risk could also exist.
Fot this reason, make sure that all cables are properly connected.
Do not supply power to the unit and do not start up operations until the
tubing and electrical connections with the outdoor unit have been
completed.
Make sure that the electrical supply is correctly connected to the units,
as shown in the electrical diagrams.
BCH -25
BCH -30

Important: The size of the circuit breaker and the cross-section of the supply and control lines are only as a guide and should be corrected in
accordance with the conditons at the jobsite, distance between units, and current legislation.

Balance point adjustment
The balance point is the lowest outdoor temperature at which
the heat pump can heat the space without the use of the
supplementary electric heaters.
The balance point depends on the following:
1) Design outdoor temperature.
2) Building's heat loss.
3) Pump's capacity.
The balance point is usually predetermined by the installation's project, but if it has not been predetermined the
factory's adjustment at 6°C can be kept.
Logic module
The control module responds to the thermostat's demand
signal, it examines the values given by the sensors outdoor,
discharge and liquid and determines if the heat pump and/or
the supplementary electric heater must operate.
Discharge sensor
It is a thermistor located in the discharge line of the
compressor, connected in series with a high pressure cutout.
It protects the compressor against high discharge temperatures (and pressures).
It stops the compressor when the discharge temperature
exceeds the set point or the pressure is greater than
28 kg/cm2.
It protects the compressor when there is a refrigerant leak or
a flow reduction through outdoor or indoor coils.
It allows the reset of the compressor circuit after a lockout
condition, by removing the power supply to the control
module, or pressing the reset button.
Outdoor sensor
This is a thermistor located in the air intake of the outdoor coil,
that registers the air temperature.
It controls the heat pump operation, stopping it when the
outdoor temperature nears -15 °C. This prevents the
compressor from operating at a high compression ratio that
could damage it.
Allows the connection of the duct electric heater (optional)
controlled by the 2nd stage of the room thermostat if the
outdoor temperature is less than -15 °C.
It allows by means of the balance point for the adjustment of
the temperature at which the supplementary electric heater
should come into operation.
Utilization limits
Liquid sensor
It is connected in the liquid line of the outdoor coil.
This sensor starts the defrost cycle after 30, 60 or 90 minutes
from start or last defrost cycle depending on selection, if the
temperature it senses is -5 °C or less.
Indicates the end of the defrost cycle when the liquid
temperature reaches 13 °C or stays at a minimum of 7 °C
during 1 minutes.
Prevents the cycle from starting in mild climates since
sufficiently low liquid temperatures are not detected.
The initial time reading for defrosting of 30, 60 or 90 minutes
is nominal. These times assume an exterior temperature of
2°C, a highly unfavourable level causing much frost
formation.
At lower temperatures the total humidity content of the ambient air is lower, permitting prolongation of the defrost cycles,
saving energy. For example: at -10°C exterior temperature
the initial time readings for defrost will be 60, 90 and 120
minutes.
Balance point
Prevents the operation of the supplementary heating system
when the outdoor temperature is above the balance point as
adjusted on the plaque.
This way the electric heater is not used as long ads the heat
pump is capable of meeting the space heating demand.
The balance point can be adjusted between 14 °C and -4 °C.
This way an additional outdoor thermostat is not needed.
Timer
Delays start during 5 or 2 minutes to avoid repeated starting
cycles. This way operating pressures are equalized before
the compressor is started. If the thermostat or manipulation
cause false contacts the heat pump is not affected.
It delays the start after a power supply cut, thus allowing the
line voltage to regain its normal level.
Stoppage of interior fan during defrost
This module allows the option of stopping the interior fan
during the defrost cycles. This option is only for when it is not
possible to instal an auxiliary electric heater.
- With the JP-19 bridge in position (factory standard) the
interior fan continues to function during defrosting.
- With the JP-19 bridge open (modified at jobsite) the interior
fan is deactivated.

Summer cycle diagram
Operating sequences
See relevant electrical diagrams.
Summer cycle: Thermostat in COOL position
1) The 4-way valve is activated through the thermostat.
2) If the fan operating mode in the ambient thermostat is in
CONTINUOUS, the contactor is activated and the fan
functions continuously.
3) With the logic module timing, the unit will start ip after 5
minutes.
4) When the thermostat contact connects, it activates the
contactor and starts the compressor. If the fan operating
mode is set to «AUTO», the fan starts simultaneously with
the compressor.
5) The unit will function intermittently in response to the
corresponding signal from the ambient thermostat to
satisfy the cooling demand.
6) When the unit stops at the end of an operating cycle, or
through a power failure, the logic module will not allow it
to start up again until 5 minutes have elapsed. This is to
protect the compressor by allowing the operating voltages
to even up.
7) If the diescharge pressure exceeds 28 kg/cm2, or the
discharge temperature is over 130°C, the logic module
will switch off the unit, leaving the system in lock-out.
8) To reset after a lock-out, turn the power supply to the unit
off, or set «OFF» on the thermostat and then reset
«HEAT» or «COOL».
The system will re-set and the unit will start up after 5
minutes.

Winter cycle: Thermostat in HEAT position
1) The 4-way valve is deactivated, allowing the position for
the heating circuit, which means that the indoor coil acts
as condenser and the outdoor one as evaporator.
2) If the fan operating mode in the ambient thermostat is in
the CONTINUOUS position, the contactor is activated
and the fan functions continuously.
3) With the logic module timing, the unit will start up after 5
minutes.
4) When the first stage of the thermostat connects, it
activates the contactor and starts the compressor. If the
fan operating mode is set to «AUTO», the fan starts
simultaneously with the compressor.
5) The unit will function intermittently in response to the
appropriate signals from the ambient thermostat to
satisfy the demand for heating.
6) If the unit stops, after an operating cycle, or through a
power failure, the logic module will not allow it to start up
again until 5 minutes have elapsed.
This is to protect the compressor by allowing the
operating voltages to even up.
7) If the discharge pressure exceeds 28 kg/cm2, or the
discharge pressure is over 130°C, the logic module will
stop the unit, leaving the system in lockout.
8) To reset after a lock-out, turn the power supply to the unit
off, or set «OFF» on the thermostat and then reset
«HEAT» or «COOL».
The systen will re-set and the unit start up after 5 minutes.
9) The auxiliary heater is activated when the auxiliary
heating stage of the thermostat is connected. The logic
module allows the indoor auxiliary heater to function if the
outdoor temperature is below the balance point. If the
outdoor temperature is above that set as the balance
point, the indoor heater does not function.
10) The emergency heater (complementary) is connected
when the outdoor temperature is lower than that
preselected as the operating limit (-15°C, logic module),
and the ambient thermostat demands the second heating
stage.

Defrost cycle (timed)
The ice which is produced on the outdoor coil during the
heating cycle must be eliminated when it begins to block the
coil.
The defrost cycle begins after a period selected between 30,
60 & 90 minutes from the start-up or the last defrosting, and
when the evaporation temperature drops to -5 °C or less.
The logic module activates the defrost relay, which:
- Activates the 4-way valve to go into the cooling cycle.
- Switches off the outdoor fan.
The defrost cycle finishes when the liquid temperature is
sufficiently high, measured by a thermistor 13 °C, or when, if
it does not heat up, it reaches a minimum of 7 °C for a 1 minute
period; also after 12 minutes from its beginning.
When the defrost cycle finishes, the logic module
disconnects the defrost relay, reestablishing normal
operating conditions of the heating cycle.
If the unit triess to go into another defrost cycle in less than 5
minutes, the logic module switches it off, leaving the system
in lock-out.
Operating at -15°C (optionally -5, -10, -20)
When the outdoor temperature is less than -15°C there is no
justification for running the compressor with the limited
amount of heat it generates.
If the logic module detects, through a thermitor in the exterior
air entry, a temperature lower than -15°C, it acts as follows:
- It disconnects the compressor.
- It switches on the emergency heater (if there is one
installed) controlled by the thermostat's second stage. (The
auxiliary heater will also continue to function, governed by
the thermostat's second stage).
- It leaves the indoor fan functioning under the first heating
stage of the thermostat.
Operation on emergency heat
When the thermostat operation mode is in the emergency
heat position.
- Compressor will be in lockout.
- The supplementary and emergency electric heaters, if
installed, will be controlled by the first stage of the thermostat.
Other safety features of the electric circuit
- The compressor is protected against overheating and the
failure of a phase by a solid state protector with three
sensors embedded in the windings.
- The control circuit is protected by a fuse.
- In general all the casing and components are protected by
an earth circuit.
Compressor crankcase oil heater
The compressor is equipped with an electric heater in the
crankcase, which heats the oil to prevent an excessive
concentration of refrigerant in it during the periods when it
does not operate.
If the main disconnect switch has been off for some time,
before heat pump is started switch should have been on for
at least 8 hours.
This is necessary to drive out any refrigerant that may be
accumulated inside the compressor.
Before finalising the installation
Verify that:
- The voltage is always between 198254 V or 342-436 V.
- The gauge of the supply cable is at
least that which is recommended in
the corresponding electrical diagrams.
- Instructions have been given to the
users on how to operate the system.
- The condensation drainage is
perfectly assembled and their are no
leaks in the water circuit.
- The need to clean the air filter has
been communicated.
- The guarantee split has been filled
in.
- Maintenance instructions have been
given or a contract has been made
for periodic servicing.

Operating instructions
General introduction
Start up and automatic temperature regulation are implemented by the ambient thermostat.
Locate the thermostat approximately 1.5 m. above floor level,
where no object prevents it from registering the true temperature of the room.
Do not place it on a wall where it will be exposed to direct
sunlight, or next to windows, air vents, etc. Before start up
connect the mains switch in order to eliminate the electrical
resistance of the compressor sump.
The compressor must not be started up until at least
eight hours have passed.
DSL ambient thermostat for 610 heat pump
This thermostat has been designed to proportion a precise
control of the ambient temperature and to give graphic
information of the mode in which the heat pump is operating.
It is a control with a Proportional-Differential-Integral response which, in relation to the difference between the
programmed and the ambient temperatures, varies the on/off
cycles between 3 and 7.5 cycles per hour.
The liquid crytal display (LCD) normally indicates the ambient
temperature, mode of operation, and whether the heating or
cooling system is connected.
It allows for the selection of different set points for heating and
cooling, as well as the choice of °C or °F.
The operation of the fan can be set in continuous mode, or
automatic, switching off and operating in unison with the
compressor.
The controls are located underneath a cover which prevents
their manipulation by unauthorised personnel.
Operation and start up
Start up is implemented by the controls located on the
thermostat.
1.- MODE
The operational mode of the heat pump is selected by
pressing this button. When the button is pressed the following
1.- Operational mode selection.
2.- Fan speed selection.

Maintenance
Cleaning of filters
Keep coil's air filters in good condition. Check them at least
every 15 days.
Cleaning outdoor coil
Dirt accumulation on outdoor coil should not be allowed. Coil
In cases of unrestricted discharge installations for an indoor unit
intended for ducting, the outlet must be protected with a grill.
Failure to fit this protection could result in damages being caused by the
fan turbine.
Priming the dreinage siphon
To avoid problems with water from condensation we
recommend that the drainage siphon be primed when
starting up and before the beginning of each season so as to
avoid, from the very beginning, the intake of air into this pipe.
Indoor unit discharge ducts
The indoor unit discharge, intended for ducts, is supplied
without a protective grill. When maintenance work is being
done this must be taken into account.
Check the outdoor unit periodically to see whether either the outlet or
the inlet are blocked up with dirt or leaves, etc.
The internal coil and other components of the outdoor unit must also be
periodically cleaned. Contact your concessionary or maintenance
service.
For safety reasons make sure you swich off the air-conditioner, and
disconnect it from the mains before cleaning.

Due to the shape of the filter rack the access cover to the filter
can be placed on any of the four sides of the rack or duct.
When designing the air ducts consideration should be given
to the fact that the use of this accessory, always implies a
90° rotation of the dimensions of the unit's air inlet port,
as shown in the diagram below.
Positions and general dimensions mm
Filter rack with filter
