Installation Guidelines and Procedures
Please carefully read the following procedures and guidelines for your system. Implementing these procedures and
guidelines will prepare your TowerGuard Filter System for operation
Installation and Anchoring
1. The
TowerGuard
Series filter system has been designed to easily lifted from the underneath the frame. If lifting
straps are used, place them underneath the frame so they do not come in contact with any of the filter
components. NEVER lift the system via any of the filter components.
2. The
TowerGuard
Series filter is designed for side-stream use only. The inlet to the system should draw from a
non-pressurized location, such as a cooling tower sump. This system should NEVER be installed in a
pressurized and/or full-flow application.
3. Each
TowerGuard
contains four anchor points. The system should be placed on a firm, supporting level surface
and securely anchored. Miller-Leaman recommends that a concrete pad be poured for the filter frame to rest on.
Piping and Connections
1. The TGSS-20, TGSS-24 and TGSS-30
TowerGuards
suction pipe size should be one commercial pipe size larg-
er the opening of pump inlet. Reducing the piping size may result in loss of flow. Make sure to support all piping
to and from the filter to eliminate stress on the filter components.
2. Manual valves should be installed in each line to allow the system to be isolated for maintenance. However, the
user must make sure that all valves are open prior to running the system. It is also recommended that unions be
installed on each connection to allow for easier maintenance should the system ever have to be disconnected
completely.
3. Connect the influent line from the sump to the pump. If the water level is below the pump inlet, a check valve or
foot valve should be installed. The water inlet line should NOT exceed 10 PSI.
4. Connect the effluent line from the system outlet back to the cooling tower sump (or to sweeper piping).
This line should not connect into a pressurized line.
5. Connect the backflush line from the port labeled “Backflush” to a drain. Do not place any valve or restriction in
this line and make sure this line drains to a non-pressurized location. Be sure the drain is capable of handling
the backflush flow rate. If not, a reservoir tank may be installed to collect the backflush water and allow it to
slowly drain out.
Make sure the dirty backflush water is properly disposed and meets all local code requirements.
6. Make sure the City backflush water supply line does NOT exceed 30 PSI. The end user is responsible for the
addition of a pressure controlling device in the municipal water supply line to limit the inlet line pressure to 30
PSI maximum.
