INSTALLATION & OPERATING INSTRUCTIONS
Therma-Flo
Series Pumps
MOUNTING PREPARATION
1. Find a suitable indoors mounting location where the pump is close to
the spa bath, as safely as possible, but remains inaccessible to the
person in the spa bath.
a. The pump’s suction port (inlet) must be lower than the normal
operating bath water level to ensure proper pump priming, but
higher than the spa bath suction to ensure correct draining.
When emptied, the water must drain back into the spa bath as
required by Health Department Regulations.
b. The discharge port (outlet) should be lower than the water level
and the plumbing should be horizontal or rise slightly to
prevent airlocks. Airlocks will prevent the pump from properly
priming.
2. This pump is intended for permanent installation only and must not be
used in portable service application. The mounting surface must be
constructed from durable material and supported securely in a
horizontal position.
3. A clearance of at least 7.5 cm (3”) on all sides (top, sides, front, and
back) is required for ease of installation and air circulation. Enclosures
must be adequately ventilated to promote free flow of air and prevent
condensation.
4. Provision for securing the plumbing leading to the pump must be
considered to avoid undue stress to the pump’s connections.
5. The pump requires 220-240 Volts A.C., 10 amperes minimum, 50 Hz,
single-phase power supply supplied through a Residual Current Device
(RCD) with a rated tripping current not exceeding 30 mA.
Above are the minimum requirements required for installing this pump.
Additional requirements, standards, and codes, mandated by government
agencies on specific areas where the pump will be installed, must be followed.
