4.13 ASSEMBLY PROCEDURE
4.14 FIXING THE CONDENSING UNIT
The condensing ELFO SHALL BE INSTALLED IN
POSITION ACCESSIBLE technician in safely, otherwise
the CAT (service centers) may refuse the intervention.
THE CONDENSING MUST NOT BE INSTALLED AS
OUTSIDE IN WINTER MAY CAUSE DAMAGE.
Depending on the installation requirements:
1.
Choose the installation path based on the structure of the
house.
2.
Secure the support of external units ON or OFF position
with expansion screws.
3.
Place the outdoor unit on the stand.
4.
Fix the holes in the feet of outdoor unit with bolts
at least three feet above the floor.
- Connect the unit and connecting pipes condensing unit
Inner.
- Connect the vacuum pump to the fitting (suction), set in
motion and make sure that the needle drops to - 0.1 MPa
(-76O mm. Hg). Before disconnecting the vacuum pump
check that the vacuum indicator remains stable for> 15
minutes.
- Close the service valve and disconnect the vacuum pump.
Notes:
- Take protective measures sufficient during the outdoor unit
installation.
- Make sure the media can withstand at least four times the
weight of the unit.
- The unit must be installed at least 10 cm from the floor to
install the drain pipe.
Do not bend the copper pipe with tight
radius after the tube has been isolated,
it may break.
INSTALLATION
4.15 CAUTION BEFORE CONNECTING THE PIPES
4.16 ISOLATION OF THE COOLING PIPE
4.17 INSULATION AND TAPING OF COMMON ENDS OF PIPES
1.
During transport and storage, prior to use, always keep the
tubes sealed with a cap or with tape to prevent the ingress of
water, dust and dirt.
2.
Always lubricate with freezing oil flange surfaces of the
nipples and union before connecting them. This facilitates
good sealing of the joint.
• The piping to the entire unit, including, the distribution
connector (purchased separately) must be applied thermal
insulation.
• For the gas pipes, the insulation material must be heat-
resistant to temperatures of 120 ° C or higher. For other
piping, it must be heat resistant to temperatures of 80 ° C
or higher.
• Wrap the pipe unions with insulating coprirubinetti or white
ribbon, then cover it with the insulation and seal with black
ribbon. Finally fix the insulator at both ends with plastic hose
clamps (after checking the system leak test).
• The refrigerant lines (and electrical wiring if allowed by local
laws) should be taped together using reinforced adhesive
tape. The drain tube must be left separate.
• Wrap the tape from the outside unit. to get to the top where
3.
Keep the flanged pipe, the nipples of the joint and well-
aligned union, then tighten the union by hand to achieve a
good contact between the flange and the pipe nipples.
• The thickness of the insulation must be suitable to ensure
minimum heat loss and prevent condensation and dripping.
• In the case where there are the conditions inside the false
ceiling that exceed 30 ° C in temperature and 70% relative
humidity, increasing the thickness of the insulation of an
increase of the gas pipe.
the pipe enters the wall. Overlap the tape for about half its
width.
• Attach the pipes to the wall with brackets arranged at 1
meter intervals.
