dictated by the specific design of the system and the unit.
Flexible connectors are required on all duct connections to
minimize air leaks.
Closed loop and pond applications: require specialized
design knowledge. No attempt at these installations should
be made unless the dealer has received specialized training.
WARNING!
Always wear hand and eye
protection when handling,
installing, servicing or main-
taining equipment. Sharp or
pointed edges, moving parts
and flying debris may cause
personal injury.
Codes and 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 I, and C.S.A. Standard B52 Mechanical Refrigeration
Code and local Plumbing or Waste Water Codes.
WARNING!
It is the responsibility of the
installing contractor to com-
ply with codes, ordinances,
local and municipal building
laws and manufacturer’s
instructions. Personal injury
and/or equipment damage
may result if proper proced-
ures are not followed.
Handling
Be aware of what is contained in the equipment.
Dependent upon the optional accessories ordered this
equipment may contain fragile components and delicate
electronics. Although the unit is constructed of sturdy
materials, it is advised to avoid impacts and handling
methods that may damage internal apparatus and struc-
ture, or the exterior 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.
Location
It is recommended that the heat pump should be centrally
located in relation to the distribution system. It is recom-
mended that the unit is installed within the applicable
area. However, in areas where temperatures may reach
freezing point unit must not be exposed to ambient con-
ditions. If not, unit may have a severe freeze damage
which warranty does not cover. The unit must be installed
level and care should be taken to prevent damage to the
cabinet. Other installation provisions may be necessary
according to the job specifications.
Service and Installation Clearance
Before setting unit 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.
HPX water source heat pumps require a minimum of 20
inches of service clearance on the access panel’s side of
the unit in order to ensure enough room for removal,
replacement or service of coils and other components if
necessary.
Mounting and Suspension
An auxiliary (emergency) drain
pan is recommended for all
applications where there is a
risk of water damage to sur-
rounding structure or furnish-
ings. Refer to local codes.
