Mounting Bolt Location /

foundation for Installation

Securely attach the Space II unit as shown
in Figure 12, using pad, base rails, or other
mounting platform that is securely anchored
to the ground or building structure. Refer to
the dimensional drawing in the "Product Data"
section, and follow the applicable local code
for clearance, mounting, anchor, and vibration
attenuation requirements.
The underlying structure or foundation must
be designed to support the weight of the unit.
Avoid placing the unit in a low lying area where
water may accumulate.
Any installation deficiency may cause unit to
fall down, resulting in a personal injury.
A: Corners must be firmly attached, otherwise, the support will bend.
B: Use a 3/8 inch anchor bolt.
D: Insert cushion pad between Space II unit and base support to ensure sufficient anti-vibration coverage.
E: Pipe and wiring space.
F: H-beam support.
G: Concrete base support.
• When deciding on a location to place the Space II unit, choose an area where run-off from defrost mode will not accumulate and freeze
on sidewalks and driveways.
• Do not install a tube or pipe for the water in the base pan. Follow the drain path to properly remove condensation.
• Do not install the suction hole and the discharge hole of the unit so that either directly faces seasonal winds as this can cause freezing.
