HP Series Installation Manual | 8
Pre-Installation
Prior to beginning installation of the HP HVAC system, the required tools should be obtained,
and all contractor-supplied parts (indicated as parts “By Others” throughout this manual) should
be gathered.
Required Tools
In order to assemble an HP HVAC system the following tools and supplies are required:
1 Hammer
2 Socket Set, common imperial and sizes
3 Box-end wrenches – various sizes
4 Pipe Bender
5 Screwdriver Set, including standard flathead and Phillips
6 Caulking
7 Caulking Gun
8 Metal Snips
9 Hacksaw
10 Plumbing Tape
Required Components
The following components must also be supplied to complete the installation:
Electrical Disconnect Switches
Disconnect switches must be supplied to isolate the humidifier for maintenance and in the case
of emergency. If the control panel and disconnect is to be located outdoors, NEMA rated
disconnect switches should be used per national and local codes.
Sizing High Pressure Stainless Steel Tubing
Stainless steel piping must be supplied for distances between the HP pump module and the HP
manifolds. These distances should be kept to a minimum to minimize pressure losses and
maximize system performance, however it is important to avoid over-sizing the lines. For most
installations a 1/2” line is appropriate. Stainless Steel Pipe Fittings
Stainless steel compression fittings are required for all high-pressure line connections. When
using swage type fittings to connect feed lines together, use fittings of the same material as the
feel lines. Never use a brass compression fitting on a stainless steel tube, as the brass will not
properly hold the harder stainless steel pipe.
Follow manufacturers instructions when installing fittings.
Recommended tube material: 304L stainless steel tube, ½” Outside Diameter, 0.049” Wall
thickness
Recommended fittings: 316 stainless steel, ½”, double ferrule compression connections.
