Prior to mounting the vacuum pump, ensure the building structure and support brackets have adequate

load characteristics to support the pump. Refer to Chart 3.1 below.

NOTE: The average sound level of PB Series vacuum pumps is between 60 and 63 DBA. If the

application requires a lower decibel level, relocation of the pump or a sound-deadening enclosure may

be necessary. Contact factory.

Following an engineered design layout:

Install vacuum pump as shown on plans. Ensure the pump is properly aligned with the system.

Allow an 8-in. to 12-in. space between the primary damper and the vacuum pump inlet adapter for

the isolation boot.

Using self-tapping sheet metal screws, mount the inlet and outlet adapters to the vacuum pump and

seal the joints with a high temperature sealant. NOTE: The NC-7 pump does not require an inlet

adapter or isolation boots).

Install both isolation boots and secure with the hose clamps provided (Figure 3.2).

WARNING

Improper suspension of the heating system may result in collapse and being crushed.

Always suspend from a permanent part of the building structure that can evenly support

the total force and weight of the heater.
