Installation
• Make provisions for disconnecting and cleaning of the
primary drain line should it become necessary. Install
condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection
as shown in Figure 7. Design the depth of the trap
(water-seal) based upon the amount of ESP capability
of the blower (where 2 inches [51mm] of ESP capability
requires 2 inches [51mm] of trap depth). As a general
rule, 1-1/2 inch [38mm] trap depth is the minimum.
• Always vent the condensate line when dirt or air
can collect in the line or a long horizontal drain line
is required. Also vent when large units are working
against higher external static pressure than other units
connected to the same condensate main since this may
cause poor drainage for all units on the line. WHEN A
VENT IS INSTALLED IN THE DRAIN LINE, IT MUST
BE LOCATED AFTER THE TRAP IN THE DIRECTION
OF THE CONDENSATE FLOW.
• Auxiliary drain line should be run to a place where it will
be noticeable if it becomes operational. Occupant should
be warned that a problem exists if water should begin
running from the auxiliary drain line.
• Plug the unused drain connection with the plugs
provided in the parts bag, using a thin layer of Teflon
paste, silicone or Teflon tape to form a water tight seal.
• Test condensate drain pan and drain line after installation
is complete. Pour water into drain pan, enough to fill
drain trap and line. Check to make sure drain pan is
draining completely, no leaks are found in drain line
fittings, and water is draining from the termination of the
primary drain line.
Charging the System
See Compressor Section IOM for charging information.

CAUTION!
�
CAUTION!
It is recommended that an auxiliary/secondary
drain pan be installed under units containing evaporator
coils that are located in any area of a structure where
damage to the building or building contents may occur as
a result of an overflow of the coil drain pan or a stoppage
in the primary condensate drain piping.
