5 Installation information for coil tanks
The tank must be placed on a firm base and adjusted in using the position
screws at the bottom of the tank. Those models without positioning
screws can be adjusted in with a liner. This must be done before the tank
is connected to the pipes and before it is filled with water. Connections
which are not used must be suitably plugged. Condensation may form on
the outside of the tank while it is being filled, which may be indicated by
an accumulation of water on the floor beneath the tank. This
condensation will stop once the tank heats up. There must be a floor
drain in the same room.
