BALTIC R410A-IOM-0708-E Page 4
All Baltic Units are compliant with the PED directive 97-23/CE
The following note must be followed carefully
All work on the unit must be carried out by a qualified and authorised employee.
Non-compliance with the following instructions may result in injury or serious accidents.
Work on the unit:
The unit shall be isolated from the electrical supply by disconnection and locking using the main isolating switch.
Workers shall wear the appropriate personal protective equipment (helmet, gloves, glasses, etc.).
Work on the electrical system:
Work on electric components shall be performed with the power off (see below) by employees having valid electrical
qualification and authorisation.
Work on the refrigerating circuit(s):
Monitoring of the pressures, draining and filling of the system under pressure shall be carried out using connections
provided for this purpose and suitable equipment.
To prevent the risk of explosion due to spraying of coolant and oil, the relevant circuit shall be drained and at zero pressure
before any disassembly or unbrazing of the refrigerating parts takes place.
There is a residual risk of pressure build-up by degassing the oil or by heating the exchangers after the circuit has been
drained. Zero pressure shall be maintained by venting the drain connection to the atmosphere on the low pressure side.
The brazing shall be carried out by a qualified brazier. The brazing shall comply with standard NF EN1044 (minimum 30%
silver).
Replacing components:
In order to maintain CE marking compliance, replacement of components shall be carried out using spare parts, or using
parts approved by Lennox.
Only the coolant shown on the manufacturer’s nameplate shall be used, to the exclusion of all other products (mix of
coolants, hydrocarbons, etc.).
CAUTION:
In the event of fire, refrigerating circuits can cause an explosion and spray coolant gas and oil.

TRANSPORT -HANDLING
BALTIC R410A-IOM-0708-E Page 11
DELIVERY CHECKS
On receipt of a new equipment please check the following
points. It is the customer’s responsibility to ensure that the
products are in good working order:
-The exterior has not been damaged in any way.
-The lifting and handling equipment are suitable for the
equipment and comply with the specifications of the
handling instructions enclosed here-in.
-Accessories ordered for on site installation have been
delivered and are in good working order.
-The equipment supplied corresponds to the order and
matches the delivery note.
If the product is damaged, exact details must be confirmed
in writing by registered post to the shipping company within
48 hours of delivery (working days). A copy of the letter
must be addressed to Lennox and the supplier or
distributor for information purposes. Failure to comply will
invalidate any claim against the shipping company.
RATING PLATE
The rating plate provides a complete reference for the
model and ensures that the unit corresponds to the model
ordered. It states the electrical power consumption of the
unit on start-up, its rated power and its supply voltage. The
supply voltage must not deviate beyond +10/-15 %. The
start-up power is the maximum value likely to be achieved
for the specified operational voltage. The customer must
have a suitable electrical supply. It is therefore important to
check whether the supply voltage stated on the unit's rating
plate is compatible with that of the mains electrical supply.
The rating plate also states the year of manufacture as well
as the type of refrigerant used and the required charge for
each compressor circuit.
Fig. 1
STORAGE
When units are delivered on site they are not always
required immediately and are sometimes put into storage.
In the event of medium to long-term storage, we
recommend the following procedures:
-Ensure that there is no water in the hydraulic systems.
- Keep the heat exchanger covers in position (AQUILUX cover).
-Keep protective plastic film in position.
-Ensure the electrical panels are closed.
-Keep all items and options supplied in a dry and clean
place for future assembly before using the equipment.
MAINTENANCE KEY
On delivery we recommend that you keep the key which is
attached to an eyebolt in a safe and accessible place. This
allows you to open the panels for maintenance and
installation work.
The locks are ¼ turn + then tighter (figure 2).
CONDENSATE DRAINS
The condensate drains are not assembled when delivered
and are stored
in the electrical panel with their clamping collars.
To assemble them, insert them on the condensate tray outlets
and use a screwdriver to tighten the collars (Figure 3).

INSTALLATION
BALTIC R410A-IOM-0708-E Page 17
FORKLIFT PROTECTIONS
REMOVE THE FORKLIFT PROTECTIONS BEFORE INSTALLATION
PRELIMINARY CHECKS
Before installing the equipment, the following points MUST
be checked:
-Have the forklift protections been removed?
-Is there sufficient space for the equipment?
-Is the surface on which the equipment is to be
installed sufficiently solid to withstand its weight? A
detailed study of the frame must be made beforehand.
-Do the supply and return ductwork openings
excessively weaken the structure?
-Are there any obstructing items which could hinder the
operation of the equipment?
-Does the electrical power available correspond to the
equipment's electrical specifications?
-Is drainage provided for the condensate?
-Is there sufficient access for maintenance?
-Installation of the equipment could require different
lifting methods which may vary with each installation
(helicopter or crane). Have these been evaluated?
-Ensure that the unit is installed in accordance with the
installation instructions and local applicable codes.
-Check to ensure that the refrigerant lines do not rub
against the cabinet or against other refrigerant lines.
In general, make sure no obstacles (walls, trees or roof
ledges) are obstructing the duct connections or hindering
assembly and maintenance access.
INSTALLATION REQUIREMENTS
The surface on which the equipment is to be installed must
be clean and free of any obstacles which could hinder the
flow of air to the condensers:
-Avoid uneven surfaces
-Avoid installing two units side by side or close to each
other as this may restrict the airflow to the condensers.
Before installing a packaged Rooftop unit it is important to
understand:
-The direction of prevailing winds
-The direction and position of air flows.
-The external dimensions of the unit and the
dimensions
of the supply and return air connections.
-The arrangement of the doors and the space required
to open them to access the various components.
CONNECTIONS
-Ensure that all the pipe-work crossing walls or roofs
are secured, sealed and insulated.
-To avoid condensation problems, make sure that all
pipes are insulated according to the temperatures of
fluids and type of rooms.
NOTE: The AQUILUX protection sheets fitted to the finned
surfaces must be removed prior to start up.

POSITIONING ROOFCURBS
As levels are adjustable, observe the following
recommendations when installing the equipment.
Above all, ensure that all the adjustable returns are facing
outward (“1” figure 17). They are usually turned inside-out
for transport.
Place the roof mounting frame on the trimmer beam by first
lining up the inlet and the outlet opening. (“2”-figure 18)
After levelling the frame, secure the adjustable returns on
the trimmer.
It is important to centre the unit on the roof frame.
