Removing Existing Condensing Unit
1.
To pump down condensing unit. Close the liquid line
service valve of existing condensing unit and start
compressor to pump refrigerant back into compres-
sor section. Then close suction service valve while
compressor is still running to trap refrigerant in
outdoor section. Immediately kill power to the
condensing unit.
2.
Remove old condensing unit. Disconnect power and
low voltage. Cut or unbraze line set from unit.
Remove condensing unit.
3.
If condensing unit is not operational or will not
pump down, refrigerant should be recovered using
appropriate equipment.
Air Handler Installation
Although the air handler section of this manual does not
contain a comprehensive installation instruction it does
provide many useful diagrams and tables specific to the
GT-S and Air Handler combined system. The airhandler
mounting should be installed according to the instruc-
tions provided with the air handler itself.
GT-S Location
Locate the unit in an outdoor area that allows easy loop
and lineset access and also has enough space for service
personnel to perform typical maintenance or repairs. GT-
S units are usually installed on a condensor pad directly
outside the lineset access into the building. The service
valve side can be located toward the building keeping the
loop access end away from the building. Conform to the
following guidelines when selecting unit location:
1.
Provide adequate access for loop trench excavation.
2.
Locate directly outside lineset penetration as
possible. Utilize existing condensor pad where
possible.
3.
Provide access for servicing and maintenance.
GT-S Mounting
GT-S unit may be mounted on an ASP2436P air pad with
loop access hole as shown in Figure 1. When mounting
on an existing concrete condenser pad 3" holes can be
bored through to accomodate the pipe (1-1/4") and 1/2"
insulation. Figure 2 illustrates the dimensions of the
holes required.
