Condensate Drain Connections

Each S_HF unit is provided with two or six 1" evaporator condensate drain connections (one on each side of the unit). Each S_HG unit is provided with two or six 1-1/4" evaporator drain connections (one on each side of the unit.)

Due to the size of these units, all condensate drain connec- tion must be connected to the evaporator drain connec- tions. Refer to the appropriate illustration in Figure 3-2 for the location of these drain connections.

A condensate trap must be installed due to the drain con- nection being on the "negative pressure" side of the fan. In- stall the P-Traps at the unit using the guidelines in Figure 3- 6.

Pitch the drain lines at least 1/2 inch for every 10 feet of horizontal run to assure proper condensate flow. Do not al- low the horizontal run to sag causing a possible double-trap condition which could result in condensate backup due to "air lock".

Units with Gas Furnace

Units equipped with a gas furnace have a 3/4" CPVC drain connection stubbed out through the vertical support in the gas heat section. It is extremely important that the conden- sate be piped to a proper drain. Refer to the appropriate il- lustration in Figure 3-2 for the location of the drain connec- tion.

Note: Units equipped with an optional modulating gas furnace will likely operate in a condensing mode part of the time.

An additional 1-1/4" non-connectable water drain is located in the base rail within the heating section.

Ensure that all condensate drain line installations comply with applicable building and waste disposal codes.

Removing Compressor Assembly Shipping Hardware (20 through 60 Ton)

Each manifolded compressor assembly is rigidly bolted to a mounting rail assembly. The rail assembly sets on four (4) rubber isolators. The assembly is held in place by two ship- ping braces that secure each compressor rail assembly to

the unit's base rail. To locate and remove the shipping hard- ware, refer to Figure 3-7 and the following procedure.

1.Remove the four anchor bolts (2 front and 2 rear), used to secure the shipping brace to the unit's base rail (two assemblies on 40 through 60 Ton units).

2.Remove the three self-tapping screws that secure each shipping brace to the compressor mounting rails.

3.Remove and discard the two 30-1/2" long shipping braces for each assembly.

4.Do not remove the shipping bracket located on top of the compressors.

5.Ensure that the compressor rail assembly is free to move on the rubber isolators.

Removing Compressor Assembly Shipping Hardware (70 & 105 Ton)

Each manifolded compressor assembly is rigidly bolted to a mounting rail assembly. The rail assembly sets on six (6) rubber isolators. The assembly is held in place by four (4) shipping "Tiedown" bolts. To remove the shipping hardware, follow the procedures below:

1.At each "Tiedown" location (2 front and 2 rear), remove and discard the tiedown bolt and the slotted shipping spacer located between the compressor rails and the unit base rail illustrated in Figure 3-7B, "Tiedown Bolt" detail.

2.Remove the bolt in each rubber isolator and the slotted shipping spacer located between the compressor rails and the unit base rail illustrated in Figure 3-7B, "Isolator Bolt" detail. Reinstall the bolts at the same location by screwing them into the base rail two to three turns only.

3.Ensure that the compressor rail assembly is free to move on the rubber isolators.

Removing Compressor Assembly Shipping Hardware (115 and 130 Ton)

Each manifolded compressor assembly is rigidly bolted to a mounting rail assembly. The rail assembly sets on eight (8) rubber isolators. The assembly is held in place by six (6)

"Tiedown Bolts". To remove the shipping hardware, follow the procedure below:

1.At each "Tiedown" location (6), remove and discard the tiedown bolt and the slotted shipping spacer located be- tween the compressor rails and the unit base rail illus- trated in Figure 3-7C, "Tiedown Bolt" detail.

2.Remove the bolt in each rubber isolator and the slotted shipping spacer located between the compressor rails and the unit base rail illustrated in Figure 3-7C, "Isolator Bolt" detail. Reinstall the bolts at the same location by screwing them into the base rail two to three turns only.

3.Ensure that the compressor rail assembly is free to move on the rubber isolators.
