Unit installation

P11 OF 38
Find the cooling/heating load capacity of the space where the unit will be in service. Select matched WMMS units
for the space. Under sizing or over sizing equipment is NOT recommended.
Mini Split Wall Mount Systems come with three types: cooling only and heat pump and heat pump with electric
heater. These units can be easily wired. Either indoor unit or outdoor unit can be used with any matched
comparable outdoor unit or indoor unit as long as they have matched size and control. Must refer to electrician
before doing so.
* Indoor unit operates much quieter than air diffuser of central air conditioning system.
* Stylish design of indoor unit adds beauty to rooms.
* Connection pipe, refrigerant usage is much saved compared to installing up-flow condensing units on the
ground and long copper/wire lines needed between indoor and outdoor units.
* Contractor work is eased and time is saved.
* Efficiency and lifetime of system is increased.
IMPORTANT NOTES FOR UNIT OPERATION ABMIENT & SIZING
Since the outdoor units can be installed on a wall or balcony (close to the indoor unit) the following are some
benefits for contractors and customers:
Each system is thoroughly tested before leaving the factory. Each unit is acoustically, thermally and
systematically designed to give optimum quality and reliability.

UNIT ENGINEERING SUBMITTALS-MECHANIAL
Mini Split Wall Mount Systems are designed for high performance, easy installation and service. Each system
consists of one or several indoor units and one outdoor unit, which are connected by one set or several multiple
sets of interconnection refrigerant pipes and electric wires.
As shown in the following sample picture of outdoor unit, air is drawn through the coil from the rear side and then
discharged from the front side. In cooling mode, air passing through coil is heated; in heating mode, air passing
through coil is cooled.

Outdoor unit(s) provides the electrical and thermal power for the whole system. Electrical and thermal
components such as compressors and motors and heat exchange coils and others, are incorporated into the
cabinet in an optimized order. They can be either hung on the wall or installed on the ground. Once stacking or
bracket kit is used, some outdoor units can be stacked 2 or 3 units high, upon unit size and applications. Air is
discharged horizontally, quietly and smoothly. These units are perfect fit in locations where installation and
applications of general up-flow condensing units are limited, such as apartments, condos, lofts, multi-families and
high-rise buildings and others named or unnamed.
Indoor unit(s) delivers the thermal and acoustical comfort to the rooms. Air is drawn through the coil from the
front or topside and then discharged from the bottom. In cooling mode, air passing through coil is cooled; in
heating mode, air passing through coil is heated. Air is filtered or treated by the built in mechanism (washable or
enzyme equipped or electrostatic powered filter, varies from model to model), before being delivered into the
room, with more than enough comfort and care, at a wide angle (swing or not, varies from model to model).
NOTES: Since ductless system is not designed to incorporate or use with ducted return or discharge
tunnels, one single-zone unit SHALL NOT be used to take care of the cooling or heating load of more
than one-story room. Several single-zone ductless systems or multiple-zone ductless systems shall be
proper in this regard.
These units are designed for applications at:
* Residential
* Light commercial
* Commercial
* Hospital
* Institutional
* Industrial
Apartments
Hotels Homes
