What precautions should be taken with flood damaged HVAC equipment?

IN THE INTEREST OF PUBLIC SAFETY, ECR INTERNATIONAL, INC. SUPPORTS WARNINGS ISSUED BY THE AIR CONDITIONING, HEATING AND REFRIGERATION INSTITUTE (AHRI) THAT RECOMMEND THE REPLACEMENT OF ALL FLOOD DAMAGED HVAC EQUIPMENT REGARDLESS OF ITS AGE. 

Replacing only the operating controls of flood damaged HVAC equipment may not be sufficient if other parts of the equipment like piping, venting, burners, insulation, etc., have been effected by the flood waters. 

IT IS ALWAYS SAFER TO REPLACE RATHER THAN REPAIR 

What types of products does RetroAire manufacture?

RetroAire manufactures replacement PTAC/PTHP chassis for almost any non 16 x 42 unit, found in a wide variety of properties. RetroAire also produces water source console units. 

What is a retrofit PTAC/PTHP?

A retrofit PTAC/PTHP is a replacement of an older model PTAC/PTHP using the existing wall box and replacing the chassis, resulting in only minor installation costs.

What information is needed to identify a replacement for an older model PTAC/PTHP?

The dimensions of the old chassis, length, width and height; model model number, voltage, amps, control box location, and capacity of the unit to be replaced need to be identified to ensure the correct replacement is selected.

Can RetroAire supply PTACs other than those in the selection guide?

RetroAire will be more than happy to look at producing replacement PTACs/PTHPs that may not be in our listing, if there are sufficient quantities to warrant the development of the product. Contact our Sales Department to discuss your replacement requirements.

Where is the transformer located in an EMI system?

In an EMI system, the 24-volt transformer is usually located in the outdoor condensing unit. If you are using an EMI evaporator with anything other than an EMI condensing unit, you MUST add a 40VA transformer.  Effective December 1, 2004 all America Series products will be manufactured with the 24 volt transformer mounted in the air handler. Please see Product Bulletin 04001 for more details.

What length line sets are allowed for your units?

You can run up to 100 ft. (30.5 M) maximum length, to include up to 35 ft (10.6 M) in vertical rise. Consult the IOM or Tech Guide for P-trapping requirements within the run.

Consult the Installation and Operation Manual (IOM) of the outdoor condensing unit or the Service and Technical Guide (STG) for P-Trap requirements for the refrigerant piping run. These documents can be obtained from our website under the Documents heading.

What are the criteria for selecting the low ambient option?

If the system will be operating for extended periods of time at 60 degrees F or below, the low ambient option should be added.

Once I have a Return Authorization from you, how long do I have to return the parts to the factory?

90 days.

Metering devices vary, so what type of meter is used in EMI evaporators?

Depending on the unit, EMI uses a piston device (chatleff assembly with a fixed orifice) or TXV.
