1.4 R410A Refrigerant
Danger!
Risk of injury due to incorrect work on the refrig-
a
R410A fl uorinated greenhouse gases are contained within
a fully sealed system (Kyoto Protocol PES 1975). Under
normal use and conditions, the refrigerant is not dangerous.
Degassing refrigerant fl uid into the atmosphere is prohibited,
except when necessary to ensure personal safety.
The refrigerant fl uid contains gases that, when released into
the atmosphere, may aff ect the environment, contributing
to the greenhouse eff ect and an increase in temperature.
The risk of leakage cannot be excluded for devices intended
to operate for many years and subject to the eff ects of the
environment.
erant circuit!
The appliance contains refrigerant fluid and must
be handled with caution. Any work on the refrigerant circuit must be performed by trained and
approved personnel.
• Only work on the refrigerant circuit if you are a
trained and approved specialist equipped with
appropriate protective equipment.
• Perform draining and filling operations in a
properly ventilated area.
• Avoid any contact with the skin or eyes.
0020154078_00 - 02/13 - Glow-worm
∙ Use only R410A refrigerant.
∙ The tools used for charging, for measuring pressure, for
creating a vacuum and for the recovery of the fl uid must be
compatible with and employed solely for R410A.
3
SAFETY
∙ Welding is to be carried out with nitrogen and the circuit’s
air-tightness is to be tested under pressure, with nitrogen.
∙ Refi lling must be done at the liquid phase.
∙ In case of leakage, do not add fl uid: drain the remaining
fl uid from the circuit and eliminate, in accordance with the
applicable regulations.
∙ Create a vacuum in the circuit with a maximum pressure of
10 mbar (10 x 102 Pa) (static pressure).
∙ Bleed the circuit before any welding work.
∙ Comply with the values given in chapter 10 when charging
with refrigerant.
1.5 Intended use

NOTES ON THE DOCUMENTATION
2 Notes on the documentation
∙ These instructions consist of, Installation, Servicing, Fault
Finding and Replacement of Parts. The instructions are an
integral part of the appliance and must be handed to the
user on completion of the installation.
2.1 Observe other applicable documents
- An anti-freezing protection device runs the heat pump
hydraulic pump when the hydraulic circuit temperature is
lower than 3°C. However, it is necessary to add anti-freeze
to the heat pump hydraulic circuit. Without the addition
of outside energy or in the case of a power cut, the circuit
water can drop below the freezing point.
3.2 Concept of operation
A heat pump (HP) is a thermodynamic machine which
transfers heat from one location to another. To do so, it
employs the characteristics of a refrigerant fl uid.
∙ Observe absolutely all operating and installation
instructions enclosed with the product, for the various
parts and components of the system.
2.2 Storing documents
∙ Pass these instructions and all other applicable documents
to the system user.
The system user should retain these instructions so that they
are available when required.
2.3 Validity of the instructions

- The appliance is designed to operate with an outside
temperature between -20°C and 35°C in heating mode and
between -20°C and 46°C for tank heating.
- A high pressure switch limits the operation of the
appliance when the refrigerant fl uid pressure exceeds
41.5 bar (gauge pressure) (41.5 x 105 Pa) (relative pressure).
- When the appliance is shut down, the compressor
crankcase heater is activated below 7°C at the compressor
outlet to prevent any damage when restarting.
- If the compressor outlet temperature is below 1°C, the
appliance will not allow the compressor to start.
- A temperature sensor at the compressor outlet limits
the operation of the heat pump when the temperature
measured by this sensor is higher than the maximum
limit. This value varies depending on the evaporation and
condensation temperatures.
- The appliance is equipped with a measuring device that
checks the water fl ow rate at start-up.
