Never use ﬂ exible hoses smaller than 1" inside diameter

on the unit and limit hose length to 10 ft. per connection.

Check carefully for water leaks. Figure 3 shows a

manifold being used in an earth loop application. Flow

(pressure drop) and temperature measurements in the

conﬁ guration will represent the total ﬂ ow going through

both coaxes regardless of which refrigerant circuits are

active. Figure 4 illustrates a well system using individual

connections. Flow and temperature measurements will

represent each refrigerant circuit.

Condensate Drain

Each unit utilizes a condensate hose inside the cabinet as

a trapping loop, therefore an external trap is not necessary.

Figure 5 shows typical condensate connections.

Each unit must be installed with means to ﬂ ush or

blowout the condensate drain line. Do not install units

with a common trap and/or vent.

Install a vent in the condensate line of any application

which may allow dirt or air to collect in the line. Always

vent when the application requires a long, horizontal

run. When some sagging in the condensate line may be

anticipated (as in a long line of plastic pipe) or when

“double trapping” may occur. Also vent when large units

are working against higher external static pressure that

other units connected to the same condensate main since

this may cause poor drainage for all units on the line.

Figure 5. Typical drain connection

To make the connection to a ground loop system, mate

the brass loop connection against the rubber gasket in

the swivel connector, and thread the female locking

ring onto the pipe threads, while maintaining the brass

connector in the desired direction (see Figure 2). Tighten

the connectors by hand to provide a leak proof joint.

When connecting to an open loop (ground water) system,

thread any 1" MPT ﬁ tting (PVC or copper) into the swivel

connector and tighten in the same manner as noted above.

The open and closed loop piping system must include

pressure/temperature taps for serviceability.
