IF YOU WILL INSTALL THE UNIT ON THE
GROUND OR ON A CONCRETE MOUNTING
PLATFORM, DO THE FOLLOWING:
• Mark the positions for four expansion bolts based
on dimensions in the Unit Mounting Dimensions chart.
• Pre-drill holes for expansion bolts.
• Clean concrete dust away from holes.
• Place a nut on the end of each expansion bolt.
• Hammer expansion bolts into the pre-drilled holes.
• Remove the nuts from expansion bolts, and place
outdoor unit on bolts.
• Put washer on each expansion bolt, then replace
the nuts.
• Using a wrench, tighten each nut until snug.
• Ensure the unit is level.
STEP 4: CONNECT SIGNAL AND POWER
CABLES
The outside unit’s terminal block is protected by
an electrical wiring cover on the side of the unit.
A comprehensive wiring diagram is printed on
the inside of the wiring cover.
BEFORE PERFORMING ELECTRICAL
WORK, READ THESE REGULATIONS
• All wiring must comply with local and national
electrical codes, and must be installed by a licensed
electrician.
• All electrical connections must be made according
to the Electrical Connection Diagram located on the
side panels of the indoor and outdoor units.
• If there is a serious safety issue with the power
supply, stop work immediately. Explain your reasoning
to the client, and refuse to install the unit until the
safety issue is properly resolved.
• Power voltage should be within 90-100% of rated
voltage. Insufficient power supply can cause
electrical shock or fire.
• If connecting power to fixed wiring, install a surge
protector (Ideal-Air
TM
700522) and main power
switch with a capacity of 1.5 times the maximum
current of the unit.
• If connecting power to fixed wiring, a switch or
circuit breaker that disconnects all poles and has a
contact separation of at least 3mm/.125" must be
incorporated in the fixed wiring. The qualified technician
must use an approved circuit breaker or switch.
• Only connect the unit to an individual branch
circuit outlet.
DO NOT
connect another appliance
to that outlet.
• Make sure to properly ground the air conditioner.
• Every wire must be firmly connected. Loose wiring
can cause the terminal to overheat, resulting in
product malfunction and possible fire.
•
DO NOT
let wires touch or rest against refrigerant
tubing, the compressor, or any moving parts within
the unit.
Before installing a wall-mounted unit, make sure that
the wall is made of solid brick, concrete, or of similarly
strong material.
The wall must be able to support
at least four times the weight of the unit.
• Mark the position of bracket holes based on
dimensions in the Unit Mounting Dimensions chart.
• Pre-drill the holes for the expansion bolts.
• Clean dust and debris away from holes.
• Place a washer and nut on the end of each
expansion bolt.
• Thread expansion bolts through holes in mounting
brackets, put mounting brackets in position, and
hammer expansion bolts into the wall.
• Check that the mounting brackets are level.
• Carefully lift unit and place its mounting feet
on brackets.
• Bolt the unit firmly to the brackets.
TO REDUCE VIBRATIONS OF
WALL MOUNTED UNIT
If allowed, you can install the wall-mounted unit with
rubber gaskets to reduce vibrations and noise.
WHEN DRILLING INTO CONCRETE, EYE
PROTECTION IS RECOMMENDED AT ALL
TIMES.
