INSTALLATION
UNPACKING -
Move unit to final location. Remove plastics wrap
from unit being careful not to damage or cause scratch to the unit.
Check the shipment against shipping list and remove unit protective
covering. If the unit has been damaged, file claim with transportation

PRIOR TO INSTALLATION OF THE 07KHP
UNITS, REVIEW THE FOLLOWING IMPORTANT
POINTS
CEILING MOUNTED INSTALLATION
Select a suitable location for the unit. For example, use
Kitchen or Bathroom ceiling spaces.
Make sure that there is enough ceiling clearance between unit
and slab. Check unit's dimensional drawing. Clearance should
also be allowed for ceiling acoustic treatment and piping.
To design steel frame for unit's base, do not place unit directly
on the ceiling. Use a strong hanging suspension when
installing the steel frame to slab.
Ensure there is sufficient clearance between hanging rods
and cabinet access panels, so that service work can be
carried easily. See the back page drawing for details.
Place the unit onto the steel frame and make sure that the
unit is leveled. Use vibration isolators between unit and steel
frame. Do not use rubber blocks as isolators.
Vibration isolators are also required for water pipe and
refrigerant tube connections. Care should be taken with
refrigerant piping to avoid any transmission of noise and
vibration to the ceiling or walls. Provide enough pipe flexibility
before fixing unit to the structure.
Provide access panel in ceiling. Make sure the panel is
located near the unit for easy maintenance and servicing.
After the unit is installed and pipe work are completed, be
sure to insulate the unit's surroundings with acoustic
treatment. An acoustic type insulation can be used for
additional sound reduction.

Make sure that enough space clearance for unit. Check unit's
dimensional drawing. Clearance should be also allowed for
acoustic treatment and piping.
To design a compartment complete with access panel or door
for maintenance and servicing the unit.
Use vibration isolators between the unit and floor. Do not
place the unit directly onto the floor.
After the unit is installed and pipe works are completed, be
sure to insulate the unit's internal compartment with acoustic
