(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

According to the manual: Float-type low water cutoff (when provided by others) 1. Install low water cutoff as shown in Figure 16, below. See Table 4 and Figure 3 on page 7 for actual tapping location. 2. Install blowdown line in bottom of cutoff. See control manufacturer’s instructions for details. Pipe blowdown line near floor close to floor drain to eliminate potential of severe burns. Do not plug, valve or place any obstruction in blowdown line. 3. Water feeders are not recommended for primary control. A low water cutoff with pump controller is recommended with a condensate receiver and feed pump. The manual does mention draining but not if and/or when it had to be done. Below is a link to the manual which you can also view/down load from the Resources and Downloads section for the item on our site. http://static.appliancesconnection.com/attachments/D576c1e560005e.pdf If you require more information you can contact the manufacturer directly.
