For Units With Space 
Limitations

In the event that a space limitation exists, we will 

permit the following clearances:
Single-Unit Applications: Clearances below 6" 

[15.2 cm] will reduce unit capacity and efficiency. 

Do not reduce the 60" [152.4 cm] discharge or the 

24" [61.0 cm] service clearances.
Multiple-Unit Applications: When multiple 

condenser grille sides are aligned, a 6" [15.2 

cm] clearance is recommended for 1.5 and 2 

ton models and 9" [22.9 cm] for 2.5 ton to 5 ton 

models. Two combined clearances below the 

minimum will reduce capacity and efficiency. Do 

not reduce the 60" [152.4 cm] discharge or 24" 

[61.0 cm] service clearances.

Customer Satisfaction Issues

•  The heat pump should be located away from the 

living, sleeping, and recreational spaces of the 

owner and those spaces on adjoining property.

•  To prevent noise transmission, the mounting pad 

for the outdoor unit should not be connected to 

the structure and should be located a sufficient 

distance above grade to prevent ground water 

from entering the unit.

Unit Mounting

WARNING:

Secure an elevated unit 

and its elevating stand in order to prevent tipping. 

Failure to do so may result in severe personal 

injury or death.

Elevation of Unit

If elevating the heat pump, either on a flat roof or 

on a slab, observe the following guidelines.

•  If elevating a unit on a flat roof, use 4" x 4" 

[10.2 cm x 10.2 cm] or equivalent stringers 

positioned to distribute unit weight evenly and 

prevent noise and vibration.

•  Where snowfall is anticipated, raise the unit 

above the base pad to prevent ice buildup and 

coil damage. Mount the unit high enough to be 

above the average accumulated area snowfall. 

See “Ground Snow Depth” chart on page 10 for 

representative snow depths.

NOTICE:

 Do not block drain openings on 

bottom of unit.
•  If unit must be elevated because of anticipated 

snowfall, secure unit and elevating stand such 

that unit and/or stand will not tip over or fall off. 

Keep in mind that someone may try to climb on 

unit.

Factory-Preferred Tie-Down 
Method for High Wind or 
Seismic Loads

IMPORTANT:

 The manufacturer-

approved/recommended method is a guide to 

securing equipment for wind and seismic loads. 

Other methods might provide the same result, but 

the manufacturer method is the only one endorsed 

by the manufacturer for securing equipment where 

wind or earthquake damage can occur. Additional 

information is available in the PTS (Product 

Technical Support) section of the manufacturer’s 

Web sites Rheemote.net, MyRheem.com, or 

MyRuud.com and can be found as a listing under 

each outdoor model. If you do not have access to 

this site, your distributor can offer assistance.
