3.2 - Check unit
Upon receipt of shipment at the jobsite, carefully check the ship-
ment against the bill of lading. Make sure all units have been
received. Inspect the carton or crating of each unit, and inspect
each unit for damage. Ensure the shipping company makes
proper notation of any shortages or damage on all copies of the
freight bill. Concealed damage not discovered during unloading
must be reported to the shipping company within 15 days of
receipt of shipment.
NOTE: It is the responsibility of the purchaser to file all
necessary claims with the shipping company.
3.2.1 - Storage
CAUTION: DO NOT store or install console units in corrosive
environments or in locations subject to temperature or humidity
extremes (e.g., attics, garages, rooftops, etc.). Corrosive
conditions and high temperature or humidity can significantly
reduce performance, reliability and service life. Always move
units in an upright position. Tilting units on their sides may
cause equipment damage.
Upon the arrival of equipment at the jobsite, immediately store
units in their shipping cartons in a clean, dry area. Store units in
an upright position at all times. Stack units a maximum of three
units high. Use pallets to separate each layer of units. DO NOT
remove equipment from shipping cartons until equipment is
required for installation.
3.2.2 - Unit protection
Cover console units on the jobsite with either shipping cartons,
vinyl film, or an equivalent protective covering. Cap the open
ends of pipes stored on the jobsite. In areas where painting,
plastering or the spraying of fireproof material has not been
completed, all due precautions must be taken to avoid physical
damage to the units and contamination by foreign material.
Physical damage and contamination may prevent proper start-
up and may result in costly equipment clean-up.
Examine all pipes, fittings and valves before installing any of the
system components. Remove any dirt found on these components.
3.3 - Mounting the unit
1.
Unpack the unit from the shipping carton. Remove the
front cabinet by lifting up and away from the backplate.
Protect the cabinet from damage during installation by
returning it to its original vinyl pack until required.
2.
Remove compressor isolation plate shipping screws (4), as
shown in Fig. 7.
3.
Using a carpenter’s square and a level, ensure the unit is
level. Shim the unit if necessary to assure proper installation.
Poor or inadequate installation may result in noisy unit
operation or unattractive appearance.
4.
Select the proper fasteners to connect the backplate
securely to the wall.
5.
Fasten the backplate onto the wall through the screw holes
located in the back flange. Secure the subbase in place.

3.4 - Electrical wiring
WARNING: To avoid possible injury or death due to electrical
shock, open the power supply disconnect switch and secure it
in an open position during installation.
CAUTION: Use only copper conductors for field-installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
All field-installed wiring, including the electrical ground,
MUST comply with applicable local, national and regional
codes.
Consult the unit wiring diagram located on the inside of the
compressor access panel to ensure proper electrical hookup. The
installing (or electrical) contractor must make the field connec-
tions shown in Fig. 8 when using field-supplied disconnect.
Operating voltage must be the same voltage and phase as shown
in electrical data shown in Table 2.
Make all final electrical connections with a length of flexible
conduit to minimise vibration and sound transmission to the
building.
3.4.1 - Supply voltage
Operating voltage to unit must be within voltage range indicated
on unit nameplate.
