The standard design for the bohn Low Profile Evaporator incorporates a hot gas loop in the drain pan. Utilizing a hot gas  
loop is ideal for hot gas defrost applications where high temperature gas can be maintained to defrost both the evaporator  
drain pan and coil.  
For applications where cooler (lower) temperature hot gas is used for defrosting, bohn offers optional electric heater  
elements in the drain pan to ensure quick and efficient defrost of the drain pan allowing condensate to drain quickly, saving  
the hot gas for efficient evaporator coil defrost.  
If the optional electric heating element drain pan is preferred, please specify when ordering, there is no additional charge.

Recommendation is that both check valve kits are ordered: (For hot gas models with the hot gas loop drain  
pan ONLY)  
NOTE: The drain pan check valve kit can be ordered as an independent item. But the suction line check valve kit  
must be ordered with the drain pan check valve kit in order to complete the piping.  
NOTE: When using the hot gas units with a hot gas loop drain pan on 0°F applications and below, an insulated  
drain pan is required.  
The hot gas unit coolers can be used in reverse cycle hot gas defrost systems using multiple evaporators connected to one  
condensing unit. Generally, not more than one-third of the system defrosts at one time.  
During the reverse cycle defrost, the reversing valve;  
located in the compressor discharge line, diverts hot  
gas through the suction line to the evaporator. See  
piping view in Figure 1. The suction line check valve  
directs the hot gas through the drain pan loop which  
prevents condensate in the pan from freezing. The  
hot gas exits the loop at the pan loop outlet header  
and enters the evaporator through the check valve  
assembly. As the hot gas defrosts the coil, heat is  
removed from the hot gas and eventually it condenses  
into a liquid and exits the coil at the distributor  
sideport. The liquid then flows through the check  
valve of the thermostatic expansion valve bypass  
assembly, around the thermostatic expansion valve,  
and into the system liquid line. The liquid refrigerant  
then feeds other evaporators on the cooling cycle,  
evaporates, and returns to the compressor through  
their suction lines.

Hot Gas Reverse Cycle Kits (cont.)  
In the refrigeration cycle, the thermostatic expansion  
valve bypass assembly check valve only allows refrigerant  
flow through the thermostatic expansion valve and into the  
evaporator coil. As the refrigerant vapor exits the coil at the  
suction line, the check valve of the drain pan loop check valve  
assembly prevents the refrigerant vapor flow through the drain  
pan loop.  
Factory engineered assemblies (kits) are available for both  
shipped-loose and factory-installed at an additional cost to  
complete the reverse cycle piping and components. The suction  
line check valve assembly includes the suction line check valve  
and the piping for both the suction line and the connection  
to the drain pan loop inlet header. In order for the suction line  
check valve assembly to be mounted, the drain pan loop check  
valve assembly must be used. The drain pan loop check valve  
assembly includes the check valve, suction line tee and a bent  
pipe. The thermostatic expansion valve bypass assembly option  
includes the check valve, tee and necessary piping. In order for  
the thermostatic expansion valve bypass assembly option to  
be complete, a thermostatic expansion valve must be selected  
by the sales engineer. The thermostatic expansion valve  
bypass assembly option is dependent on the body style of the  
thermostatic expansion valves which includes the Sporlan SQE,  
SbF, EG and the Alco HFESC body styles. The factory-installed  
thermostatic expansion valve bypass assembly option must  
have the thermostatic expansion valve selection included on  
the order for the hot gas unit cooler.  
To increase the efficiency, higher performance and greater system protection, a heat exchanger may be beneficial to the  
system. In order to use a heat exchanger, the thermostatic expansion valve bypass assembly option must be modified. See  
the piping view in Figure 2. The modification includes rerouting the pipe from the thermostatic expansion valve bypass  
check valve to the inlet connection of the liquid line to the heat exchanger. A pipe needs to be routed from the liquid line  
outlet connection of the heat exchanger to the inlet connection of the thermostatic expansion valve.  
The electrical control option includes an adjustable defrost termination and fan delay control (DTFD) which is standard.  
For an additional cost, an optional (2) control electrical system is available with one adjustable control for defrost  
termination (DT) and one fixed control for the fan delay (FD). For both the DTFD and DT adjustable controls, the remote  
bulb position is with the bulb strapped to the piping of the thermostatic expansion valve bypass assembly option between  
the distributor sideport and the check valve. When the thermostatic expansion valve bypass assembly is shipped-loose, the  
installer will need to position the remote bulb. When the thermostatic expansion valve bypass assembly is factory-installed,  
the remote bulb should already be properly installed.

3-Pipe Hot Gas Defrost  
The hot gas defrost unit coolers conforms to  
the standard 3-pipe hot gas system using a check  
valve assembly, an electrical control to terminate  
the defrost, and a hot gas solenoid valve. The  
check valve assembly transports the hot gas  
between the drain pan loop and the sideport  
distributor of the coil. The check valve assembly kit  
is available for shipped-loose or factory-installed  
for an additional cost.  
The electrical control option includes an  
adjustable defrost termination and fan delay  
control (DTFD) which is standard. An optional  
(2) control electrical system is available with one  
adjustable control for defrost termination (DT)  
and one fixed control for the fan delay (FD) for  
an additional cost. For both the DTFD and DT  
adjustable controls, the remote bulb position is  
with the bulb strapped to the suction line to insure  
a complete defrost. The remote bulb is positioned  
by the installer. The hot gas solenoid valve must be  
ordered separately and will be shipped-loose. The thermostatic expansion valve could be ordered separately and shipped-  
loose or the thermostatic expansion valve could be factory-installed with a liquid line for an additional cost.  
The liquid line is designed for the body styles of the Sporlan SQE, SbF, EG and the Alco HFESC thermostatic expansion  
valves. The thermostatic expansion valve needs to be selected by the sales engineer. In a typical 3-pipe, multiple evaporator  
system, the compressor discharge defrosts the evaporator. The liquid/vapor mixture of refrigerant after defrost, however,  
returns to the common suction line of the system. In order to provide sufficient re-evaporation of the liquid vapor mixture  
and sufficient heat for defrost, no more than one-third of the system should be defrosted at one time. Some means of  
control in the 3-pipe hot gas system should be supplied to regulate the large amount of liquid returning to the compressor,  
refrigerant slugging can otherwise damage the compressor.
