CODES AND REGULATIONS

General

The GPHM5 SEER2 M-Series heat pumps are designed 

for OUTDOOR USE ONLY. The GPHM5 SEER2 M-Series 

is available in cooling capacities of 2, 2.5 3, 3.5 and 4 

nominal tons of cooling. Optional field installed heat kits 

are available in 5, 8, 10, 15 and 20 kW. The units can be 

easily installed in manufactured or modular homes with 

existing high-static duct work. The units can also be easily 

converted to accommodate a plenum for normal or low-

static applications. The GPHM5 SEER2 M-Series are 

self contained packaged units so the only connections 

needed for installation are the supply and return ducts, the 

line and low voltage wiring and drain connection. Rated 

performance is achieved after 20 hours of operation. 

Rated performance is delivered at the specified airflow. 

See product specification sheet for packaged models.
