Introduction
Congratulations! When you chose the Jifon heat pump, you chose a heat pump system which
is a more energy-saving concept than traditional heat pumps. e system examines a list of
parameters to ensure that the operation always is machine-friendly and energy-effi cient.
How much heat a house needs, is dependent on many diff erent factors. During a part of the
year, the house gets enough energy from the sun, people and household appliances. e house
often needs more heat during autumn, winter and spring. How much more is necessary to
keep the house warm, depends on the insulation of the house, the type of domestic heating
system installed, the outdoor temperature, the weather conditions and losses through ventilation.
JiControlTM, the control panel of the system, handles this for you by fl oating condensation,
which is by only producing as much heat as the house needs to maintain an even indoor temperature.
Introduction
5AH-01
Always follow the safety instructions in this manual as well as on signs and markings on and
around the machine in order to prevent damage to person and machinery.
e heat pump may only be used in accordance with the instructions in this manual. All other
use is forbidden. Incorrect use caused by not following the instructions in this manual may
result in damage to property, and at worst in personal injury.
If problems arise with the AquaHeatTM heat pump, refer to the Troubleshooting chapter before
you contact Jifon. If you need a service engineer, only contact authorized service engineers. All
adjustments, other than room temperature are strictly forbidden.
All maintenance work must only be carried out by authorized personnel.

Introduction
Operation
Two copper pipes are connected to the evaporator. One pipe transfers fl uid to the AquaHeatTM.
e other pipe transfers energy fi lled gas to the heat pump module. Energy is transferred
to the buildings hydronic heating system by the heat pump module. e heated water is then
pumped around the building.
1. e heat gathering part - low pressure
is part of the heat pump is called the evaporator (AquaHeat
TM
). A refrigerant with a low
temperature fl ows through the evaporator. e
AquaHeatTM is heated by water, evaporating the
refrigerant.
2. e preassure rising part - High pressure
is part consists of a compressor. e heated
and evaporated refrigerant is compressed by the
compressor. e increase in pressure raises the
temperature and condensation point (the point
where gas returns to liquid form).
3. e heat emitting part - High pressure
is part of the heat pump transfers the heat to
the house and is called the condensor. e
refrigerant passes through the condensor at a
high temperature and condensation point. In the
condensor, the refrigerant is cooled down by the
heating system of the house (such as radiators
or fl oor heating), leading to the condensation of
the refrigerant (returning it to liquid form).
4. Pressure lowering part - Low pressure
is part consists of a throttling device. e
cooled refrigerant expands and both the temperature and the boiling point of the refrigerant
is signifi cantly lowered as a result of the lower
pressure.

Air Temperature Sensor
e control panel controls the heating system for the entire house and has one digital thermostats.
e digital thermostat MCX controls the temperature in the room where the air temperature
sensor is placed. e air temperature sensor is to be placed in a suitable location in the house.
Read more about the air temperature sensor below. It also controls the temperature of the hot
water from the heat exchanger safety. e control panel also controls the pressure in the compressor (high or low pressure).
e air temperature sensor measures the actual temperature of the room/house. e sensor
provides data for the heat pump control panel to work with.
It is important that the air temperature sensor is placed in a room (or in a location) in the
house where the highest average temperature is required. e air temperature sensor has to be
placed where it is changed by the Jifon heating system of the room/house such as fl oor heating
and radiators and not by local sources of heat such as lamps, stoves, and direct sunlight. e
air temperature sensor should not be placed on external walls.

Temperature Regulation
e regulation of the temperature in the house is done with the digital MCX control. e
factory default setting air temperature setpoint is 21°C.
When the air temperature sensor measures a temperature that is 0.1°C below the control panel
value the compressor is started with a delay of 500 seconds. If the measured temperature is
0.5°C below the control panel value the boost is started, this also occurs with a delay of 500
seconds. If fl oor heating is used the boost should be set to not start until the measured temperature is 1.0°C below the control panel value, see Installer Manual.
When there is no temperature diff erence between the air temperature sensor value and the
control panel value the compressor and the additional heating is turned off .
e heat pump has a default setpoint setting of 21°C. To change the air temperature setpoint
use the Up/Down button.

e factory setting is 50°C and must only be changed by Jifon AB or authorized personnel.
e compressor is automatically shut off at the setpoint value (50°C) to protect the compressor and it starts again when the water temperature is 5°C below the setpoint value.
Additional heating should be installed if it is not already installed.
During the coldest months of the year the heat pump might need additional heating to keep
a constant temperature within the building. If the heat pump is forced to maintain an indoor
temperature that is higher than its performance capacity and no additional heating is available
it has to work continuously, thus not giving the heat pump the off times it needs. is can
result in the evaporator freezing up to a point when its effi ciency is lowered.
e diff erent heat pump modules can be connected to all hydronic heating systems such as district heating, electric element, oil- , gas-, or pellet boiler.
This value must only be
changed by Jifon AB or
authorized personnel.
NOTE!
All radiators must have
open valves in the rooms
that are to be heated.

Compressor Startup (only three phase unit)
Refilling and Deareating
e compressor is a three-phase unit that is sensitive to the rotation direction and can be damaged
if in operation with a faulty rotation direction during longer periods of time. To change the rotation direction, switch two incoming phases. Check the compressor drive at operation start-up.
During normal operation:
e peak pressure increases rapidly1.
e suction pressure decreases rapidly2.
e hot gas pipe is warm within 5-10 seconds after start-up3.
During faulty rotation direction:
e compressor is loud1.
e peak pressure does not changed2.
e suction pressure does not changed3.
After operation start-up of the heat pump the following is to be checked:
e water pressure1.
at there is no air in the radiator circuit or in the circulation pump2.
Operation Start-up
After a pressure test and a vacuum drive are performed on the heat pump, refrigerant can be added.•
Connect a manometer to the valves of the low- and high pressure pipes.•
Add refrigerant until the high pressure warning is turned off .•
e compressor can now be started, letting it draw additional refrigerant from the low pressure pipe.•
If the condensation is exceptionally high this might be because there is to much refrigerant in the •
system or it might be due to bad circulation.
Bad circulation is usually caused by:
e circulation pump•
Air in the system•
Closed valves•
e water fl ow has been wrongly connected through the heat pump•
To be able to quickly start the compressor, the setting on the
control panel displays must be changed (see Delay Setting on
page 25). In operation mode this is set to 500 seconds but can
be set to 10 seconds during operation start-up or service.

as fl oor heating and radiators, and not by any local heat source such as lamps, stoves or direct
sunlight. e air temperature sensor should not be placed on external walls.

Planning Manual
Additional heating should be installed if not already installed.
e heat pump might need som assistance from additional heating during the coldest months
to maintain a steady temperature. If the heat pump is pressured to keep a indoor temperature
higher that its performance and if there are no additional heating, the AquaHeat will have to
work continuously and by doing so, not allowing it to have the breaks it need. is can result
in lowering its eff ect.
e diff erent heat pump modules can be connected to all hydronic heating systems (that acts
as additional heating) such as district heating, electric element, oil- , gas-, or pellet boiler.
Additional Heating and Water Heating
Constant circulation is needed if
pre-heating should work. To achive
constant circulation all radiators need
to have open valves.
NOTE!
Domestic Hot-water for Households
Jifon recommends installing pre-heating when heating domestic hot-water.
Within the Jifon solution, pre-heating of domestic hot-water is preferred. A single-jacket and
insulated water heater is installed in the house. e water entering the heater and its mixing
valve have already been heated by the hydronic heating system of the house. is is best done
with a plate heat exchanger. With this solution the heat pump stands for the largest contribution during the winter. During the summer, almost half of the energy is drawn from the house,
acting as a large solar collector.
e benefi ts of pre-heating are drastically lowered domestic hot-water costs for a small investment together with disburdening the heat pump from the high load required when producing
domestic hot-water.
