Air Handler Installation Instructions
Electric and Hydronic
PIPING:
HOT WATER PIPING:
If a residential water heater is used for space heating water,
do not exceed a distance of 70’ between the air handler and
the water heater. The water heater should be the quick
recovery type. Air handler and water heater must be
located indoors and not subject to freezing temperatures.
WARNING:
Air handler must be located so that if any connections
should leak, water will not cause damage to the adjacent
area. When such locations can’t be avoided, a suitable
drain pan should be installed under the air handler, not
over 1-1/2” deep, with minimum length and width at least
2” greater than the air handler dimensions and
connected to an adequate drain. Under no circumstances
is the manufacturer to be held libel for any water damage
in connection with this air handler.
Total piping should not exceed 140’. All piping should be
¾” copper or approved PVC. It is recommended that the
water shut-off valve for the water heater be located close
to the water heater. Isolation valves are also
recommended.
It is recommended that any devices installed, which could
create a closed system, have a by-pass and/or the system
have an expansion tank to relieve the pr
essure built up by
thermal expansion in the water system.
WARNING:
Toxic chemicals such as used for treatment of boilers or
non-potable water heating appliances shall never be
introduced into a potable water space heating system.
WARNING:
When the system required water at temperatures higher
than required for other uses, a means such as a mixing
valve shall be installed to temper the water for those uses
in order to reduce the scald hazard potential.
After piping has been installed, allow the system to fill
with water and check connections for leaks. To insure
complete filling of the system, follow start-up procedure.
CONDENSATE DRAIN PIPING:
The air handler “
A” coil drain pan has two ¾” NPT
female primary and two secondary connections (left or
right hand). Horizontal pan has two ¾” NPT female, one
primary and one secondary. Piping from each fitting used
is to have 1-1/2 minimum trap and each run in such a
manner as to provide enough slope for adequate drainage
to a visible area. Do not pipe these two fittings together
into a common drain. Cap unused connection.
