Rheem Heatpump Installation Manual
There are many kinds of water heaters, from electric heat pumps to hydronic heating systems. While each type has its own uses, these systems are required to meet a very unique set of criteria if they are going to perform effectively. For installers, it’s important they have access to correct information when they make the decision to invest in a water heater. Even within a single product class, different models have unique specifications that installers will need to consider prior to investing in a certain system. Why should you access Rheem’s product manuals? At Rheem Thermal, we are passionate about providing the full range of information that help you make educated decisions. In addition to a comprehensive warranty policy for all of the products we offer, we provide expert advice and support for our full range of water heaters.
To help, we’ve outlined the main issues that might prompt you to access our range of pool heating product manuals, across both new installations and existing products. Choosing a new water heater When installers first approach the task of installing a new water heater, they will need to know the product’s details in order to ensure it matches relevant specifications of a project.
When heating a commercial pool, for example, the heating unit will be just one part of a larger system designed to ensure the pool operates smoothly. Furthermore, installers will have to make specific considerations regarding the water heating units they choose.

There are a number of further factors that buyers will need to consider, from how heat is supplied to how much energy is consumed. These will all be affected by the existing scope of an initiative, and project managers will need access to this information before they pursue with particular models. Ongoing maintenance for a heating unit Once a unit has been installed, it is equally important those in charge of facility maintenance have access to in-depth information on unit performance. When the operator undertakes scheduled servicing, having access to this information will make it much easier to inspect a unit and assess its condition.
Likewise, if a facility undergoes an upgrade or installs new equipment that might affect an existing water heating unit, this library of information can ensure your existing machinery continues to perform.

Rheem Heat Pump Installation Instructions
If you have any problems with the registration process or your account login, please. My dad recently had a 3 ton rheem heat pump and air handler installation. This was a replacement for old equipment.
I was on site when the installation was done as my dad is getting up in his years and asked me to be there. The installer was a Certified Master HVAC contractor. The following are some things I noticed about the install and would like some feedback to address my questions. 1) A new (3/8' / 3/4') 35' line set was used for this R410A installation with only 30' of the line set being used. A new filter drier was installed on the liquid line about 5' from the outside units service port. Heat Pump IAQ thermostat was installed. The Rheem owner manual states the unit has a factory charge for a 15' line set.
The installer said the unit was operating properly and needed no additional freon charge? When the new line set was brazed at the unit and air handler the installer did not use a nitrogen purge flow while brazing. The owners manual states when brazing R410A line sets nitrogen should be used.
Thermostat is working but not in the auto mode to change form heat to air automatically. What I would like to know is what steps should be taken at this point. I look forward to hearing from someone.

Nothing wrong with that The Rheem owner manual states the unit has a factory charge for a 15' line set. The installer said the unit was operating properly and needed no additional freon charge? Hopefully he set the charge by using manufacture's charging chart When the new line set was brazed at the unit and air handler the installer did not use a nitrogen purge flow while brazing. The owners manual states when brazing R410A line sets nitrogen should be used. 99.9% of all equipment is installed without nitro purge. Thermostat is working but not in the auto mode to change form heat to air automatically. Nothing wrong with that.
Most high end tstats have many options. Look at the paper with pictures on it. Set it how you want it. What I would like to know is what steps should be taken at this point. I look forward to hearing from someone. Thanks,It would be nice if everyone would purge.
With nitrogen. But it's not going to happen. And my price is compared with theirs. Something that's really important to the operation of your equipment is airflow. I would make sure my return-air and duct work is sized right. Many thanks guys for replying back to my concerns.
The reason I mentioned the length of the line set was the unit only comes with a 15' line set charge of 410A from the factory. With the line set being an additional 18' longer being a total of 33' (.6 ounces x 18' = 10.8 ounces of freon charge that needs to be added for recommended operating level. This is information I found on the internet from multiple sources. I know that no additional freon was added because I asked the installer if he added any 410A to the system. (He said: My gauges show that the system pressure is correct and the refrigerant lines feel about right on temperature so no additional charge is needed.) From what I have read the proper refrigerant charge should be determined by Subcooling Charging Method for this equipment since it has an expansion valve. From other information I had gathered I was concerned about him not using the nitrogen purge, Since this appears to be the guideline for R410A. I do know that when R22 was the mainstream refrigerant nitrogen was always used during the manufacturing process for brazing.
I know this because I was a York International employee for many years. Brazing heat pumps, condensers and cased coils. 'Hope you guys have not found any leaks on the York equipment, lol.' I also know that many installers of R 22 units never used nitrogen while installing equipment.
So for R22 equipment it was not a big deal. Just had a concern on the R410A equipment.
As far as the thermostat goes it works well and the equipment is operating as it should. I thought something may not be wired correctly since the auto mode does not change form heat to air as it should concerning the thermostat. Since the install was to include any additional refrigerant if needed, I just want to be sure things are done properly.
No need in paying a service call in the future if it happens to need an additional charge of R410A. As far as the duct sizing goes I do notice an air whistling sound coming from the vents that I didn't notice on his old equipment. Many thanks for the replies. Thanks for answering me back Baldloonie. Thermostat auto changeover has been programmed into the IAQ and shows up on the display just does not perform the auto function. Just wondering if anyone on the forum here has ever looked on the inside of copper tubing brazed without nitrogen.
Being an old brazer from my manufacturing days I can assure you if cut open the copper line set after brazing without nitrogen you will see a significant difference of the ash type trash on the inside of the line set. As to whether it has an adverse effect on the R410A equipment in the long haul is another story. I do know it didn't have a major effect on R22 equipment. On the thermostat there is a 3° to 5° differential between Heating and cooling depending on how it was set up.
Thats to protect the compressor. If you have the stat set up correctly and it's going pass the set point and not initiating a system call, then you either have a defective stat or it was not set up correctly to start with. As far as the use of Nitrogen?? I already stated that this usually starts a argument. But the evaporator and the lineset both come with Nitrogen in them,( In a NEW SYSTEM) so if you open one end and work fast enough, there generally is no need to bleed Nitrogen into the lineset. Like I said, on humid days, I will bleed some through, but not to often and I have never had an issue. I do know of one contractor in New Jersey that installed a LOT of 'York, blue fin' coils, those things leak like a screen door on a submarine.

As far as I know, York is not giving him any support on changing them out ( No labor allowance) which sucks, so he stopped doing business with York and he use to do a LOT of business with them. He is changing them out on his own, but it's costing him a fortune. Quick Navigation. Site Areas. Forums.
