Condensate And Water Connection - ClimateMaster Trilogy Q-Mode (QE) Series Manual

Condensate Piping
Pitch the unit toward the drain to improve the condensate
drainage.
Install condensate trap at each unit with the top of the trap
positioned below the unit condensate drain connection as
shown in Figure 9. Design the depth of the trap (water-
seal) based upon the amount of External Static Pressure
(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.
Each unit must be installed with its own individual trap and
connection to the condensate line (main) or riser. Provide
a means to flush or blow out the condensate line. DO NOT
install units with a common trap and/or vent.
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.

Condensate and Water Connection

Water Connections-Residential (Distributor) Models
Residential models utilize swivel piping fittings for water
connections that are rated for 450 psi (3101 kPa) operating
pressure. (Note that units with an internal variable-speed
pump and flow meter have a maximum pressure rating of
100 PSI [689 kPa]). Pressure in excess of 100 PSI (689
kPa) will damage the unit. The connections have a rubber
gasket seal similar to a garden hose gasket, which when
mated to the flush end of most 1" threaded male pipe fittings
provides a leak-free seal without the need for thread sealing
tape or joint compound. Check for burrs and ensure that the
rubber seal is in the swivel connector prior to attempting any
connection (rubber seals are shipped attached to the swivel
connector). DO NOT OVER TIGHTEN or leaks may occur.
The female locking ring is threaded onto the pipe threads
which holds the male pipe end against the rubber gasket,
and seals the joint. HAND TIGHTEN ONLY! DO NOT
OVERTIGHTEN!

WARNING! Polyolester Oil, commonly known as POE oil, is
a synthetic oil used in many refrigeration systems including
⚠ those with HFC-410A refrigerant. POE oil, if it ever comes
in contact with PVC or CPVC piping, may cause failure of
the PVC/CPVC. PVC/CPVC piping should never be used
as supply or return water piping with water source heat
pump products containing HFC-410A as system failures and
property damage may result.
