3. Installation
General
H2/V2 air handling units are designed as a self-
contained heating, cooling, or combination unit for
indoor installation only. The use of refrigerant, chilled
water, electric resistance, steam, or hot water as
operating mediums will be dictated by design of the
heating and cooling coils installed in the unit. Flexible
connectors are required on all duct connections and
installed to minimize air leaks.
Certification
Cooling Models
a) Certified for use with a commercial
condensing or chilled water remote unit (with
or without compressor(s))
b) Certified for indoor installation only.
Steam or Hot Water Heat Models
a) Certified for indoor installation only.
Electric Heat Models
a) Certified as an electric warm air furnace with
or without cooling coil.
b) Certified for indoor installation only.
Codes & Ordinances
System should be sized in accordance with National
Warm Air Heating and Air Conditioning Association
Literature, or the Guide of American Society of
Heating, Refrigeration and Air Conditioning Engineers.
The installation must conform with local building
codes, or in the absence of local codes, with (United
States) “ANSI / UL 1995”, (Canada) current, C.S.A.
Standard C22.2, No. 236, Canadian Electrical Code
Part 1, and C.S.A. Standard B52 Mechanical
Refrigeration Code, and Local Plumbing or Waste
Water Codes.
Handling
Be aware of what is contained in the equipment!
Dependent upon the optional accessories that were
ordered, this equipment may contain fragile
components and delicate electronics. Although the
unit is constructed of sturdy materials, avoid impacts
and handling methods that may damage internal
apparatus and structure, or the exterior painted
surfaces of the unit. Take care not to apply destructive
force to coils, coil and drain stub-outs, or other parts
protruding beyond the extents of the unit casing.
Always handle the unit by its exterior casing, and
never by any of the protruding parts.
Keep equipment free from debris, and construction
waste during installation. Foreign materials may
adversely affect unit operation resulting in premature
failures that will not be covered by the manufacturer’s
warranty. Attach all service panels, and cover all
exposed equipment when work is not being performed.
Leave unit protected from other construction until start-
up is to occur.
Service & Installation Clearance
Before setting the air handler into place, caution must
be taken to provide clearance for unit panels/doors
that must be accessible for periodic service. These
areas contain the controls, safety devices, refrigerant
or water piping, shut-off valves and filter access.
H2/V2 air handlers require a minimum of 36 inches of
service clearance on the access panel side of the
unit in order to ensure room for removal, replacement,
or service of coils and other components if necessary.

It is the responsibility of the installing contractor to
comply with codes, ordinances, local and
municipal building laws, and manufacturer’s
instructions. Personal injury and/or equipment
damage may result if proper procedures are not
followed.
