NOTES ON INSTALLING CENTRAL DRAIN PAN
Make sure to design and install drain pan to cover the all drain hole on base completely.
The gap between drain pan and base should be less than 1/16in. (2mm).
Be careful of the foot place during the working or design process.
If the foundation or foot place makes working difcult, the metal ttings should be used as
shown below.
Keep in mind that a drain pan not having the recommended outside dimensions can cause a
water leakage or cannot be installed.
Gaps other than the drain holes cause a water leakage. Completely close all the gaps in the
bottom and sides by welding.
