Tank Replacement
The contents of this canister must
be reclaimed at a Trane authorized
facility. Disposal of the canister or
the contents in any other way may
be a violation of Federal CFC/
HCFC Venting Regulations.
Warning!
!
The saturation level of the activated carbon in the canister is directly related
to the accumulated pump out time on the Purifier Purge. When the pump out
time on the Purifier Purge timer reaches the value listed in line “A” or the
date on line “B” of the Change Purifier Plus™ Canister label (Figure 4) the
carbon is saturated and the canister needs to be replaced.
The most accurate way to determine if a canister needs replacement is to
weigh the cylinder. The tare weight of the carbon tank and carbon is con-
tained on a sticker on the bottom of the carbon tank (sometimes located
elsewhere on the tank). The weight is listed as pounds-ounces. For example
42-10 means 42 lbs. 10 ounces.
The amount of refrigerant that can be held within a given quantity of acti-
vated carbon depends on many variables including the carbon type, refriger-
ant type, as well as the temperature and pressure of the carbon. At typical
equipment room temperatures the Purifier Plus canister will hold approxi-
mately 12 lbs of refrigerant.
If the current tank weight is any more than 6 lbs. over the tare weight listed
on the label, it is time to exchange the tank. In the above example, any
weight over 48 lbs 10 ounces (42 lbs. 10 6 pounds = 48 lbs. 10
ounces) should be exchanged. There is no problem in exchanging a tank at
a weight between 0 and 6 lbs. over the tare weight, however.
Removing the Old Canister
The refrigerant vapor in the purge exhaust line can be pumped into the can-
ister before removing the copper lines by:
1. Disconnect and plug the ¼” line entering the pump out compressor.
2. Remove the bypass cap from the pump out compressor inlet tee and turn
on the pump out system using the purge service switch for ten to fifteen
seconds. This will pull room air into the pump out compressor and force
purge exhaust into the Purifier Plus canister.
3. Disconnect the copper lines from the full canister and cap the inlet and
outlet ports of the canister.
4. Install replacement tank and update all label information per steps 4 and
5 of the “Installation” section of this manual.
5. Reconnect the tubing and replace the cap removed in Steps 1 and 2 of
this section.
