Safety Information

Follow all safety codes. Wear safety glasses and work 

gloves. 

Use a quenching cloth for brazing operations.

 

Have a fire extinguisher available. Follow all warnings and 

cautions in these instructions and attached to the unit. Con-

sult applicable local building codes and National Electrical 

Codes (NEC) for special requirements.
Recognize safety information. When you see a safety 

symbol on the unit or in these instructions, be alert to the 

potential for personal injury. Understand the meanings of the 

words DANGER, WARNING, and CAUTION. DANGER 

identifies the most serious hazards that will result in death 

or severe personal injury; WARNING means the hazards 

can result in death or severe personal injury; CAUTION 

identifies unsafe practices that can result in personal injury 

or product and property damage.
Improper installation, adjustment, service, maintenance, or 

use can cause explosion, fire, electrical shock, or other con-

ditions which may result in personal injury or property dam-

age. This product must be installed only by personnel with 

the training, experience, skills, and applicable licensing that 

makes him/her “a qualified professional HVACR installer.”

 
 WARNING

  The installer must determine and follow all applicable codes 

and regulations. This equipment presents hazards of electric

-

ity, rotating parts, sharp edges, heat and weight. Failure to read 

and follow these instructions can result in property damage, 

severe personal injury or death. This equipment must be in

-

stalled by experienced, trained personnel only.

 
 DANGER

Hazardous Voltage!

Disconnect all electric power including remote 

disconnects  before  servicing.  Failure  to  discon

-

nect  power  before  servcing  can  cause  severe 

personal injury or death.

 CAUTION

  Use copper conductors only. Unit terminals are not designed to 

accept other types of conductors. Failure to do so can damage 

equipment.

Inspection

When the equipment is received all items should be care-

fully checked against the bill of lading to be sure all crates 

and cartons have been received. All units should be care-

fully inspected for damage when received. If any damage 

is noticed, the carrier should make the proper notation on 

the delivery receipt acknowledging the damage. The carrier 

should also fill out a carrier Inspection Report. The Daikin 

McQuay Traffic Department should then be contacted. The 

unit nameplate should be checked to make sure the voltage 

agrees with the power supply available. 
A complete unit consists of the following components, or-

dered and shipped separately.
1.  Heating/Cooling Chassis and Cabinet or Front Panel.
2.  Wall Sleeve.
3.  Outdoor Louver.
4.  Subbase – Optional for 208V and 230V units but 

mandatory for all 265V.

5.  Fixed heater with factory installed power cord.
6.  Electrical receptacle – Required for 208V and 230V units 

but mandatory for all 265V and Hydronic units.

7.  Plug cord cover – Optional for 208V and 230V units but 

mandatory for all 265V.

IMPORTANT

 

This  product  was  carefully  packed  and  thoroughly  inspected 

before leaving the factory. Responsibility for its safe delivery 

was assumed by the carrier upon acceptance of the shipment. 

Claims for loss or damage sustained in transit must therefore 
be made upon the carrier, as follows:

  VISIBLE LOSS OR DAMAGE

  Any  external  evidence  of  loss  or  damage  must  be  noted  on 

the freight bill or carrier’s receipt, and signed by the carrier’s 

agent. Failure to adequately describe such external evidence 

of loss or damage may result in the carrier’s refusal to honor 

a damage claim. The form required to file such a claim will be 

supplied by the carrier.

  CONCEALED LOSS OR DAMAGE

  Concealed loss or damage means loss or damage which does 

not  become  apparent  until  the  product  has  been  unpacked. 

The contents may be damaged in transit due to rough han-

dling even though the carton may not show external damages. 

When the damage is discovered upon unpacking, make a writ

-

ten request for inspection by the carrier’s agent within fifteen 

(15) days of the delivery date. File a claim with the carrier since 

such damage is the carrier’s responsibility.
