Description
The MRCOOL UAH18060-O is the 5-ton multi-position air handler for the Universal Series heat pump systems. It is designed for R-454B and pairs with the UHP18060-O outdoor unit.
The matching UAH air handler installs upflow, downflow, horizontal left or horizontal right, and its narrow cabinet matches the width of most furnaces, which makes furnace-to-heat-pump swaps easier. It runs on 115V or 208/230V with automatic voltage identification, uses an M-shaped all-aluminum coil, a constant-airflow ECM blower and an electronic expansion valve, and it has a built-in refrigerant leak sensor for R-454B. It works with any standard 24V thermostat.
Airflow, electrical and size
Rated airflow is 1801.1/1648.1/1500.9/1236.1/N/A (Turbo/H/M/L/Si). Without electric heat the air handler draws 14.5/10 A (115V / 208-230V; without heat kit) minimum circuit ampacity with 15 A (without heat kit) maximum overcurrent protection. It takes a 20 x 20 x 1 in filter, uses 3/8 in liquid and 3/4 in suction connections, measures 21.50 x 21.50 x 55.94 in and weighs 188.05 lbs.
Electric heat
Supplemental and emergency heat is added with an MRCOOL UHK heat kit, sold separately. This size accepts the 10 kW, 15 kW, 20 kW kits, which slide into the cabinet and bring their own circuit breakers.
Key Features
- Multi-position: Upflow, downflow, horizontal left or right

Frequently Asked Questions
Which outdoor units does this air handler work with?
UHP18060-O. Those are the AHRI-matched pairings for this size.
Which heat kits fit?
The 10 kW, 15 kW, 20 kW MRCOOL UHK kits are approved for this cabinet.
What filter size does it take?
20 x 20 x 1 in.
Can it run on 115V?
Yes. It runs on 115V or 208/230V single phase and identifies the supply voltage automatically. Any heat kit needs its own 208/230V supply circuit.
