LOW AMBIENT COOLING OPTION

PATENT PENDING

The low ambient cooling kit makes it possible to provide 100%

cooling capacity at outdoor temperatures down to -10

F while still

allowing full airflow at higher ambient temperatures and full heating

capacity if the unit switches to that mode

The kits are designed for use with the PUHY, PURY and PUHY-

HP modular outdoor units. The hood, which includes

an electronically controlled damper assembly, will modulate

its position automatically and, combined with the INVERTER–

driven fans, will provide optimum airflow at lower temperatures.

The specially designed wind deflectors will block unwanted

wind that could impede operation and, at the same

time will allow full airflow when required at higher ambient

temperatures or in heating mode. Another benefit of the

assembly is a more efficient defrost cycle when the unit is

operating in heating mode.

Complete Low Ambient Kit requires hood with control damper

assembly and wind deflectors.

Additional features

• Hood and wind deﬂectors constructed of 20 gauge

Hot-dipped galvanized G-90 steel

• Heavy-duty polyester-based powder paint ﬁnish

• Designed to work with both 208/230 and

460 3-phase units

• NEMA 4X control box protects electrical components

from the elements

• Kit easily connects to outdoor unit with plug–in

electrical connections

• Wind deﬂectors easily install with existing

(wire guard) fasteners

Mitsubishi Electric is the first

and only VRF manufacturer to offer a

low ambient cooling solution

for its 6–30 ton air source

outdoor units.

General features

Allows system to operate at 100% COOLING capacity at

reduced outdoor temperatures:

• PUHY Y-Series Outdoor Units –

(Now down to -10o FDB Outdoor Temp.)

• PURY R2-Series Outdoor Units –

(Now down to -10oFDB Outdoor Temp.)

• PUHY-HP H2i Y-Series Outdoor Units –

(Now down to 0o FDB Outdoor Temp.)

Components required

per outdoor unit(s)

For outdoor units with multiple modules, a minimum 1-3/16"

separation between the modules is recommended. If modules

are placed farther apart, than 15" apart, more than one set

of SWD-1 side wind deflectors may be needed. For multiple

units or module sets placed in a row, only one side wind

deflector kit (SWD-1) is needed to cover the two outside

module coil surfaces.
